Ultimate Guide To Understanding Solar Cell Functionality

Ultimate Guide To Understanding Solar Cell Functionality

Utilizing the sun’s power has been humanity’s dream for centuries. With the development of solar cells, this dream is now a reality. But how do these incredible devices work? This ultimate guide will delve into the fascinating world of solar cell functionality.  

And while the people of Australia are enjoying the utmost solar production, some are still curious about its functionality. Thus, this ultimate guide to understanding solar cell functionality will erase all the confusion. 

So What is A Solar Cell?

A solar cell is also known as a photovoltaic cell. This device directly transforms light energy into electrical energy via the photovoltaic effect. Most solar cells are made from silicon. These silicon-based solar cells increase efficiency and decrease cost.   

The materials vary from non-crystalline, polycrystalline, and crystalline (single crystal) silicon forms.  

Unlike batteries or fuel cells, solar cells do not rely on chemical reactions or fuel to generate electricity and do not have moving parts like electric generators. 

A solar cell is a crucial component that transforms light energy into electrical energy in photovoltaic energy conversion. Typically, semiconductors serve as the material for solar cells.  

The conversion process involves absorbing light (photon) energy, which generates electron-hole pairs in a semiconductor, followed by charge carrier separation. A p-n junction is commonly employed for this charge carrier separation.  

Understanding the fundamental properties of semiconductors and the principles of traditional p-n junction solar cells is essential for grasping the workings of conventional solar cells and newer types of solar cells.  

A thorough understanding of the p-n junction solar cell can provide insights into enhancing solar cells in terms of efficiency, production cost, energy consumption during fabrication, and more.

functions of solar cells

The fundamental physics of semiconductors is crucial for understanding the operation of p-n junction solar cells. It outlines the basic principles of p-n junction solar cells. It concludes with the concept of solar cells using nanocrystalline materials.  

The fundamental phenomena are revisited because solar cells based on nanocrystalline materials are more complex than conventional p-n junction solar cells. 

Understanding Solar Cells

Solar cells are the building blocks of solar panels. They convert sunlight directly into electricity. This process is based on the principles of the photovoltaic effect, discovered by French physicist Edmond Becquerel in 1839. 

Solar cells can be grouped into large assemblies known as arrays. These arrays of thousands of individual cells can serve as central electric power stations. These arrays can convert sunlight into electrical energy for distribution to industrial, commercial, and residential users. 

Smaller configurations of solar cells are often called solar cell panels or simply solar panels. And are installed by homeowners on their rooftops to replace their traditional electric supply.  

Solar cell panels also provide electricity in many remote locations where conventional electric power sources are unavailable or too expensive to install. Check out our off-grid technology for a better understanding.  

Solar cells are the power source for most space installations, from communication and weather satellites to space stations.  

However, solar power is insufficient for space probes sent to the solar system’s outer planets or into interstellar space due to the diffusion of radiant energy with distance from the Sun.  

Solar cells have also been incorporated into consumer products, such as electronic toys, handheld calculators, and portable radios. Solar cells in these devices can also utilize artificial light and sunlight. 

While the total production of photovoltaic energy is currently small, it is expected to increase as fossil fuel resource decreases.  

Projections based on the world’s anticipated energy consumption by 2030 suggest that solar panels operating at 20 percent efficiency could meet global energy demands and cover only about 496,805 square km of Earth’s surface.  

The material requirements would be significant but achievable, as silicon is the second most abundant element in Earth’s crust. These factors have led proponents of solar energy to envision a future “solar economy” where virtually all of humanity’s energy needs are met by inexpensive, clean, renewable sunlight.

Components of a Solar Cell

A solar cell is constructed from two semiconductors types: p-type and n-type silicon. P-type silicon is created by combining atoms with one fewer electron in their outer energy level than silicon, such as boron or gallium.   

An electron vacancy or “hole” is formed because boron has one fewer electron than is required to form bonds with the surrounding silicon atoms. 

N-type silicon is created by combining atoms with one more electron in their outer level than silicon, such as phosphorus. Phosphorus has five electrons rather than four in its outer energy level.  

It bonds with the silicon atoms next to it, but one electron is not involved in the bonding. It is instead free to move within the silicon structure. 

A typical solar comprises a semiconductor material, usually silicon, sandwiched between two metallic contacts. The silicon is mixed to create two layers: the n-type (negative) layer, which has extra electrons, and the p-type (positive) layer, which lacks electrons. 

The Structure and Functioning of Solar Cells

How Solar Cells Are Made

When sunlight hits the solar cell, the energy of the absorbed photons is transferred to the electrons in the silicon. This energy heats the electrons, enabling them to overcome the barrier between the n-type and p-type layers, creating an electric current. 

Regardless of their application, be it in a central power station, a satellite, or a calculator. Solar cells share a common structure. Light penetrates the device through an optical coating or anti-reflection layer, which minimizes light loss due to reflection.  

This layer effectively captures the light hitting the solar cell by facilitating its transmission to the energy-conversion layers beneath. The anti-reflection layer is usually a silicon, tantalum, or titanium oxide applied to the cell surface through spin-coating or vacuum deposition. 

Beneath the anti-reflection layer are three energy-conversion layers: the top junction layer, the absorber layer (the device’s core), and the back junction layer.  

Two additional electrical contact layers are required to transport the electric current to an external load and back into the cell, completing an electric circuit.  

The electrical contact layer on the light-entering face of the cell is typically in a grid pattern and made of a good conductor like metal.  

As metal obstructs light, the grid lines are as thin and widely spaced as possible without compromising the collection of the cell-produced current. 

The back electrical contact layer, which only needs to function as an electrical contact, covers the entire rear surface of the cell structure. Since this layer also needs to be a good electrical conductor, it is always made of metal. 

Given that most of the energy in sunlight and artificial light is in the visible range of electromagnetic radiation, a solar cell absorber should efficiently absorb radiation at these wavelengths.  

Materials that absorb visible radiation well are known as semiconductors. Semiconductors, even in thicknesses of about one-hundredth of a centimetre or less, can absorb all incident visible light.  

Since the junction-forming and contact layers are much thinner, the thickness of a solar cell is essentially that of the absorber. Examples of semiconductor materials used in solar cells include silicon, gallium arsenide, indium phosphide, and copper indium selenide. 

When light hits a solar cell, electrons in the absorber layer are excited from a lower-energy “ground state” to a higher “excited state,” allowing them to move through the solid.  

Without the junction-forming layers, these “free” electrons move randomly, preventing any oriented direct current. However, the addition of junction-forming layers creates a built-in electric field that generates the photovoltaic effect.  

Essentially, the electric field directs the electrons to flow past the electrical contact layers into an external circuit where they can perform useful work. 

The materials used for the two junction-forming layers must differ from the absorber to create the built-in electric field and carry the electric current.  

Therefore, these could be different semiconductors or a metal and a semiconductor. The materials used to build the various layers of solar cells are similar to those used to produce diodes and transistors in solid-state electronics and microelectronics.  

Solar cells and microelectronic devices share the same basic technology. However, in solar cell fabrication, the aim is to build a large-area device because the power produced is proportional to the illuminated area.  

In contrast, microelectronics aims to construct ever-smaller electronic components to increase their density and operating speed within semiconductor chips or integrated circuits.

How Solar Cells Are Made

Silicon is the material that similarly makes transistors in microchips and solar cells. A semiconductor is a material made of silicon.  

Some materials, particularly metals, allow electricity to flow easily through them, known as conductors.  

Other materials, such as plastics and wood, do not allow electricity to pass through them; they are insulators.  

Semiconductors, such as silicon, are neither conductors nor insulators: they do not normally conduct electricity, but we can make them do so under certain conditions. 

A solar cell is a sandwich of two layers of silicon that have been specially treated to allow electricity to flow through them in a specific manner.

The Photovoltaic Effect

The photovoltaic effect is the phenomenon that occurs when light, in the form of photons, hits a material and generates an electric current. This is the fundamental principle behind the operation of solar cells. 

If we connect this silicon sandwich to a torch, no current flows, and the bulb does not light up. But when we shine a light on the sandwich, something amazing happens. Light can be considered a stream of energetic “light particles” known as photons.  

When photons enter, they give up their energy to the silicon atoms. The incoming energy knocks electrons out of the lower, p-type layer, causing them to jump across the barrier to the upper, n-type layer and flow around the circuit.  

The more light there is, the more electrons jump to the surface, and the more current flows. This is what we mean by photovoltaic light – producing voltage—and it is one type of what scientists call the photoelectric effect.

The efficiency of Solar Cells

The efficiency of a solar cell is determined by how much of the sunlight’s energy it can convert into electricity. Factors affecting efficiency include the quality of the semiconductor material, the amount of sun the cell receives, and the cell’s temperature.

Advancements in Solar Cell Technology

Technological advancements are continually improving the efficiency and affordability of solar cells. From the development of thin-film solar cells to the exploration of perovskite materials, the future of solar energy is bright. 

Understanding the functionality of solar cells is key to appreciating the potential of solar energy. Solar power promises to play an increasingly significant role in our sustainable energy future as we continue to innovate and improve upon this technology.

How To Go Solar In Australian Apartments?

How To Go Solar In Australian Apartments

Do you live in an apartment and want to know if you can install solar panels on your building? Then you have come to the right place. The short answer is yes! But there’s much to know before installing solar panels while living in an apartment building.  

So how to go solar in Australian apartments?  

Apartment residents who want to take advantage of the benefits of solar energy have different options. Here, we’ll look at how to go solar in Australian apartments. And what you should know before making the switch. 

Understanding Solar Power

Solar energy has emerged as a leading solution in Australia as the most effective sustainable energy. For Australian apartments, the transition to solar energy might seem confusing.  

However, with the right information and guidance, it’s entirely achievable. This blog will guide you through going solar in your Australian apartment, covering everything from understanding solar power to installation and benefits. 

Navigating Corporate Body

Getting corporate body approval is a crucial step in the solar installation process. It’s essential to present a well-researched proposal highlighting the benefits of solar power, the cost and return on investment, and the installation process.

Government Incentives

The Australian government offers incentives to encourage the use of solar power. The Small-scale Renewable Energy Scheme (SRES) allows you to earn small-scale technology certificates (STCs) for every megawatt-hour of power your solar system generates. It can be sold to recoup some installation costs. 

The STC program also applies to apartment buildings. The rebate is currently worth around $600 per kW of solar panels installed and is averaged across the country.  

Our Solar Installation Partners will apply for the STC on your behalf and include this discount in your quote. That figure is decreasing yearly until it reaches zero in 2031, so the sooner you buy, the more money you’ll save! 

Other rebates are available, but they vary depending on where you live. We strongly advise you to investigate whether grants or funding are available in your area.

The Benefits of Going Solar

Going solar in Australian apartments is not only feasible but also highly beneficial. With the right approach and resources, you can overcome the challenges and enjoy the numerous benefits of solar power.  

  1. Cost Savings: Solar power can significantly reduce your electricity bills. Over time, the savings can offset the initial installation costs.
  2. Environmental Impact: Solar power is a clean, renewable energy source that reduces your carbon footprint.
  3. Increased Property Value: Apartments with solar power systems are often more attractive to potential buyers, enhancing the property’s value.

Solar Energy Is A Wise Investment for Landlords and Tenants

solar panels in apartments

For some landlords, the environmental benefits of solar power are sufficient to persuade them to invest in solar.  

Installing solar power on your rental property can improve its appeal to tenants, increase its value, and help it stand out in the rental market. This may allow you to raise your rental price to cover solar power installation costs. 

There are also solar companies that act as a middleman between the landlord and the tenant. The tenant will pay for the solar electricity at a lower rate than grid power. A portion of this money is then transferred to the landlord. 

The Challenges

Unlike standalone houses, apartments present unique challenges for solar installation. Some hurdles include shared rooftops, corporate body rules, and distributed generated power among residents.  

However, these challenges are manageable, and many Australian apartments have successfully transitioned to solar power. 

Is Your Apartment Building Eligible for Solar Energy?

A solar firm with a track record in apartment installations or an independent advisory service can offer expert guidance on the optimal choices for your building. For instance, you can still power the communal areas with a solar system if there’s limited roof space.  

Initially, examine your roof or online aerial images to identify existing structures like collaborative rooftop spaces or infrastructure. 

While some solar solutions for apartments may take several months to a year to put into action, the potential savings on bills and environmental advantages make it a worthwhile endeavour.

Solar Steps for Your Apartment Building

best solar options
  • Talk to your fellow owners and the owners’ corporation. 
  • Obtain estimated quotes, consult with a solar expert and examine different prices. 
  • Think about energy efficiency as well. 
  • Choose the best option according to your building structure. 
  • After all that, the owners’ association approves, and solar panels can be installed.  Initiate a conversation about solar energy with fellow apartment owners and your owners’ association. 

Solar Solutions for Apartments

Some common solar solutions are mentioned below. These solutions will help you enjoy the benefits of solar in your apartment. 

Solar in Public Places

Solar panels are installed on the shared roof, and the electricity generated is used to power common areas. This is frequently the simplest solution because only one electricity meter and account are involved. 

It can also be a good option if roof space is limited or if numerous common areas consume a lot of energy, such as lifts, a gym, a pool, or large air-conditioned common areas. 

It is simple to distribute the benefit equally by lowering strata fees for common areas. Because this option is limited to powering the common areas, no owner or tenant’s electricity bill is reduced.

Individual Solar Panels

Another option is installing systems linked to individual units’ electricity meters. This works well for three or fewer stories of low-rise buildings, as roof space can be allocated for each apartment’s solar system. 

Even if only some are involved, this can be a simple way for one or more residents to get solar. You may also be eligible for a rebate from Solar Victoria. You will almost certainly need the approval of your owners’ corporation.  

Consider asking your neighbours if they’re interested in going solar with you. It can benefit you with a lower price for having a shared system. You can negotiate a lower price if you install multiple systems through the same solar company.  

Once installed, this option works exactly like solar on a freestanding home, with no additional metering or monitoring equipment required and no interaction between your solar system and the systems of your neighbours.

Solar Sharing Between Neighbours

New technology distributes solar energy equally among apartments and businesses in the same building. And this option allows residents to opt-in to solar. This technology maximises the amount of solar energy used within the building.  

It can also be a good option where roof space is limited compared to the number of apartments. As new technologies emerge, more providers are expected to launch similar offers or other apartment solutions.  

If this type of solution seems appropriate for your building, research the most recent available options. Savings on individual residents’ energy bills may be worth the extra cost of enabling technology.

Agreement of Power Purchase

Your building’s owners’ corporation agreed to buy energy from a renewable source, like an on-site or off-site solar installation. A PPA leverages your collective purchasing power to secure lower renewable energy costs. 

It does not may or may not have any changes to metering or wiring. Still, it implies that participating apartments will receive two bills: one from your regular electricity provider and one from the PPA for your portion of energy.  

The sum of the two new bills will be less than your previous energy bill, resulting in savings.

Embedded Networks

All apartments in an embedded network are connected to the grid via a single meter and purchase electricity from the same retailer. These are more common in higher-density, larger apartments.  

Better electricity rates can be negotiated by pooling the purchasing power of the entire building. Being a part of an embedded network necessitates the participation of all apartments.  

And it is usually difficult or expensive for individuals who want to opt-out to change energy retailers. If you are already a member of an embedded network, you can install solar owned by the Embedded Network Operator and sell them to apartments in your building at a lower cost.  

It can be a good option for buildings with an embedded network and want all apartment owners to participate. For more information on embedded networks, go to the Australian Energy Regulator. 

New and Advanced Options

There are several new ways to purchase renewable energy that are becoming available. These include virtual power plants, microgrids, solar gardens, other ‘offsite solar’ solutions. These software platforms allow for energy trading and sharing.  

If solar is wrong for your apartment, or if you have solar on your building but want to do more, keep an eye on this space. Many of these solutions are currently in trial or pilot phases or are only available in limited quantities.

Other factors to consider

Complex solar installations, such as those on apartment buildings, incur additional costs. Find out if these will apply to your facility by speaking with a reputable solar retailer or an independent advisory service. Some of the most common extra charges are:
  • Additional metering and monitoring costs for equipment allow solar to be shared equitably among residents. Each apartment typically has its own electricity meter and account. But an apartment building’s rooftop solar system may be shared.  
  • Additional installation costs for tilt frames, longer cabling, and other hardware required to install solar on a flat roof, a concrete roof, or a tall building, for example. 
  • Additional installation costs for equipment, labour, and permits are needed. Tall buildings may require solar installers’ equipment and machinery.  
  • Costs are incurred during the planning and approvals stages. For a complicated installation, seek a solar feasibility study from a professional. There may be additional costs for legal advice or regulatory fees for some solutions. 
The majority of apartments have a mix of renters and owners. There are also ways to include tenants and landlords so everyone benefits. See our rental property guidance for more information.

5 Energy-Saving Tips with Solar During Winter in Australia

5 Energy Saving Tips With Solar During Winter In Australia

Winter brings with it the desire to stay warm, which can increase energy consumption. These five tips will help you stay warm and comfortable without emptying your pockets with high energy bills.  

So, what are the 5 energy-saving tips with solar during winter in Australia? You can also check out 10 energy-saving tips in Australia. It will provide a review of how you can save energy all year round.    

But first, let’s understand your energy usage before we get into the tips. An average Australian household spends 40% of its energy budget on heating and cooling. 

Get a smart monitor to have a better understanding of your usage habits. You can track your usage over time. It allows you to see how the seasons affect how you use energy.  

With a smart monitor/meter, you can view a daily breakdown of your usage. You can also get the weather forecast properly.  

Electricity and gas bills are out of control in Australia right now. And it gets unmanageable in winter because of the extra heating and hot water usage. However, simple changes in your daily habits can reduce your energy bills and save energy.  

Use our energy-saving guide to immediately lower your electricity bills and save money on operating costs. Running your air conditioner, washing machine, and dryer can significantly increase your energy bill.  

As winter approaches and the days become shorter, it’s an excellent time to consider your home’s energy efficiency. Since most of us spend more time at home, energy consumption increases in the daytime.  

As a result, our electricity bills may be high. Consequently, it’s essential to consider your energy consumption and the possibility of lowering your power costs. Even minor changes can result in significant savings.  

So here are 5 energy-saving tips with solar during winter for lowering your winter energy bill. 

Install Solar Panels on Your Rooftop

Covering your roof with as many solar panels as possible is a step towards energy saving. You can save more money with more solar panels! 

For starters, the demand for solar panels is growing year after year. In 2013, the average household solar panel installation was 4kW. That figure has recently risen to more than 8kW! It has more than doubled and continues to increase every year!  

The average household has doubled to 8kW in just six years. If you haven’t upgraded, your system may need to be improved for electric vehicles and other electrical appliances.  

And if your goal is to have a near-zero electricity bill, you can base it on average electricity usage. You must consider the cold winter months when solar production is the lowest and energy consumption is the highest.  

A large system allows you to compensate for more significant energy fluctuations. 

What happens if you buy an EV, batteries, and electricity for your household? Are your panels going to be ready for these extra appliances?  

Data shows that Australia’s solar output will double in five years as more solar panels are installed.  

Invest in solar today to reduce your electricity bill and carbon footprint.

Make Full Use of Your Solar Panels

renewable energy

Only installing solar panels in your home is not enough. You will need to benefit from the panels as much as possible.  

Keep these things in mind to get the best results from your solar in winter-

  • Running appliances during daylight hours is best because of the sunlight. 
  • High-energy appliances, such as your dishwasher and washing machine, should be run at different times. Again, daytime is always preferable but at another time. 
  • Charge your electrical devices during the day, when energy generation is at its peak. 
  • Turn off inactive appliances or devices and replace older appliances with energy-efficient models. 

Invest In a Solar Battery

Purchasing a solar battery is a huge investment, but it takes time to get the value back. Even if you don’t have a lot of extra energy to store, it might be worth investing in a battery anyway. It’s an investment that will profit you for a long time.  

The most common reason for purchasing a battery is that you have an electric-powered device that needs to be used after sundown or on stormy days. Some examples are using hot water, pool pumps, or charging electric vehicles.  

During blackouts, you can also use the battery as backup power.  

If you’re still heavily reliant on grid energy, this is one step closer to energy independence! With a battery, you can be optimistic that electricity will always be available without needing generators. Isn’t it wonderful to be the house with power when there’s a power outage?  

So, how much will you save by installing a battery? The simple answer is $1,000 per year. Ten years later. You’ll start saving money a decade after you install the battery. Allow us to explain. 

The most common household battery size ranges between 10kWh and 14kWh. Batteries cost $1,000 per kWh on average, so households typically invest $10,000 to $14,000 in one. A 10kWh battery system saves the average home around $1,000 per year. 

As a result, even if you save $1,000 per year, it will take approximately ten years to recoup your battery investment. And now, with Tesla Powerwalls, you can save extra!

Reduce Your Energy Consumption

During the winter, solar panels can still capture sunlight and generate energy for your home. However, because there are fewer daylight hours, your solar panels will produce less power than in the summer.  

That’s why you may need to decrease your energy usage or expect a higher electricity bill. And there are many ways to reduce your energy consumption, including:

  • Change to energy-saving light bulbs. They are more durable and perform better. A 60-watt traditional light bulb can typically be replaced with a 15-watt energy-efficient bulb. 
  • Please turn off all appliances when they are not in use. While most know that leaving these things on wastes energy, we often overlook that it impacts our wallets. 
  • Small appliances should be unplugged. Even when not in use, they can consume a small amount of electricity, increasing your energy bill. 
  • Reduce the temperature on your thermostat. You can save money by lowering your home’s temperature by a few degrees. Layer your clothing to increase your comfort. 
  • Examine the insulation in your home. If your home is poorly insulated, more heat will escape, costing you money. 

Get a Smart And Improved Heat Pump

Your heat pump works best between 18°C and 20°C. Blasts of high temperature may appear to be the most efficient way to heat a cold room. But using your heat pump will not heat your room any faster. On the other hand, it will significantly increase your energy consumption.  

Use the timer function on your heat pump to pre-heat your space for 15 minutes before you want to occupy a room. And then set it off automatically when it’s no longer needed for the most cost-effective results. 

Let’s assume you have applied all the tips to save energy in winter. But getting the most out of your solar panels requires an improved maintenance system.

So How To Maintain Your Solar Panels During Winter?

solar panels in winter

Solar panels are most known for producing energy on bright, sunny days, but they also work well in the winter. Cold temperatures will help solar panels work more efficiently.  

But cloudier days and snow will almost certainly cause solar panels to produce less energy because of less sunlight.  

Solar panels require a little more maintenance in winter to get the maximum output. And none of the tips below are mandatory. But you can generate more electricity even when the sun is down. 

Adjust The Angle Of Your Panels

The sun’s angle in the winter differs from summer. As a result, adjust the angle of your solar panels during the winter to make the most of them. But most people will only be able to do it if solar panels are not mounted on fixed. 

For those who can, adjusting the angle can help direct more sunlight to your panels.

Wipe The Snow From Your Panels

It’s natural for snow to fall in a snowy area. Automatically snow will fall onto your panels too. However, that is okay. Light snowfall will most likely melt quickly. Snow on your solar panels may be beneficial because it cleans your panels as they fall off.

Insulate Your Batteries Properly

It’s best to take a few extra measures to care for your solar batteries during the winter to ensure they function correctly. It is critical to keep your batteries at the proper temperature.  

Batteries are not designed to operate in the cold that some areas experience. Consequently, your batteries should be stored indoors or in well-insulated containers.  

If you store your batteries outside, monitor the temperature to ensure it’s within the ideal range. 

Monitor Your Battery's Discharge

It’s also critical to monitor your battery’s discharge levels. It is not advisable to completely discharge your solar batteries. While some batteries may be suitable for discharge levels ranging from 70% to 80%, the recommended discharge level is 50%. Keep an eye on your battery discharge on high usage days, likely in the winter, and consider investing in a backup generator.

Living Off-Grid Possible For Average Australian Households?

With many Australian households facing skyrocketing power bills, living off-grid does have a lot of appeal. But what exactly does it entail, and would it work for you? More specifically, is living off-grid possible for average Australian households?

As electricity prices continue to rise and renewable energy technologies become more accessible. Living off-grid, like how you currently connect to the network, has never been easier, thanks to technological advancements!

And many average Australian households are considering going “off the grid.” Meaning people are living off the grid in Australia.

Right now, off-grid power is less expensive and financially viable. There are no restrictions today like before. Living off-grid, you can have A/C, a pool, electric cooking, and even underfloor heating.

Off-Grid systems are getting popular among those seeking to be self-sufficient and less reliant on the energy grid. However, before going off-grid, we need to consider many factors.

We have done the hard part by examining the benefits and drawbacks of off-grid. So that you can easily make your choice.

Living off the grid no longer requires a tent in the woods and water dipping from a stream. Whether you want to become entirely self-sufficient or reduce your power bills, there is a solution. Let’s look at some key things to think about.

Recent advances in small-scale solar and storage technologies have enabled households to self-generate a significant portion of their energy consumption. And it’s easy to see why solar might be an appealing option.

Solar Energy

off-grid solar system

Solar panels are becoming more efficient. It means you don’t need as much roof space to power an entire household from the sun as you once did.

If your budget or space is severely limited, consider purchasing just a few panels for a solar solution that provides free hot water.

Using solar requires a few changes to your household routines according to daylight hours. Such as running appliances during the day rather than overnight.

Another option is investing in solar batteries. It lets you go completely off-grid or protect you from lengthy power outages.

Can You Use Solar Panels To Go Off-Grid?

To answer your question, yes! You can use solar panels to go off the grid. An off-grid solar system is an autonomous system. The system utilizes solar panels to produce energy and stores excess energy.

This type of system is usually for people living in remote areas. It is for people who don’t have access to the power grid.

While off-grid solar systems are self-sufficient, they can power your home or business. These off-grid systems don’t need any connection to the grid.

How Many Panels Do You Need For An Off-Grid House?

The exact number of panels you require to power an off-grid house is determined by several factors, including:

  • The average daily consumption of electricity.
  • The solar panel type and efficiency.
  • The house’s geographical location and the amount of available sunlight.

How many panels you require will depend on your household’s energy requirements. We recommend consulting a professional solar installer like Solar Emporium who can thoroughly assess your energy requirements. Solar Emporium can provide you with a solution tailored to your needs.

Notably, the number of panels required is only one factor to consider. You’ll also need to ensure to have enough battery storage. Not only will you need to generate enough solar energy to meet your needs, but you’ll also need to have enough energy for when the sun isn’t shining.

Backup energy storage will get through extended periods of low solar, such as winter and cloudy days.

It is also critical to perform regular maintenance on your batteries and panels. You must ensure your setup works properly and optimally to store enough energy to meet your needs.

The Fundamentals Of An Off-Grid Solar System:

components for living off-grid

  • Panels for solar energy
  • Solar Charge Manager
  • Solar Storage\batteries
  • AC Inverter
  • A Backup generator

What Exactly Is An Electricity Grid?

A large and complicated electricity transmission and distribution system is called the grid. Australia has four major power grids, and nearly everyone is connected to one.

  • The National Electricity Market (NEM) operates in Victoria, New South Wales, Queensland, Tasmania, South Australia, and the ACT.
  • SWIS (South West Interconnected System): A system that operates in Western Australia.
  • The North West Interconnected System (NWIS) is a system that operates in Western Australia.
  • The Darwin-Katherine Electricity Network is operational in the Northern Territory.

Electricity distribution companies manage and maintain these grids. Maintaining and upgrading these grids cost more than half of your electricity bill. Falling grid energy demand makes it more expensive for network operators to keep their systems, potentially raising electricity prices.

How Can You Reduce Your Dependence On Power Grid?

You don’t have to go off-grid to reduce your dependence on the grid. Installing a solar battery without disconnecting from the grid is an excellent middle ground. It allows you to store excess energy generated by your solar panels when the sun isn’t shining.

You can also be less stressed knowing you have a reliable energy source. It can even provide you power when the grid is down.

And, if you have a battery, connecting it to Solar Emporium’s Off-grid system allows you to increase your energy independence while earning rewards. Households that connect their home battery to our storage system can receive a monthly credit on their electricity bill.

What are The Differences Between Off-Grid And Grid-connected Solar?

  • Off-grid solar system is when solar panels don’t connect to the grid. It generates and stores electricity independently. As mentioned before, these systems are usually for remote areas. It’s for individuals who don’t want access to an electrical grid or rely on the grid.
  • In contrast, grid solar refers to a system with solar panels linked to the electrical grid. This system generates electricity and feeds any excess power back into the grid. It allows the homeowner to receive bill credits or payments for the extra power they generate.
  • It is typically used by households with electrical grids who want to reduce their energy bills using solar energy.
  • The main distinction between off-grid and grid-connected solar is the degree of dependence on the electrical grid. Grid-connected systems are linked and interact with the grid, whereas off-grid systems operate independently.
  • Off-grid systems also demand more initial investment. But with many rebates, these should be within reach for average households. Cutting the power comes with its challenges. And the most significant one comes with the possibility of going without power for long periods.

What Does It Cost To Live Off-Grid?

A dependable solar battery, a large off-grid solar system, and a backup generator are required to live off the grid. Even after government rebates and incentives, living entirely off-grid will cost at least $20,000-$25,000.

The average Australian household consumes between 12 and 16 kWh of electricity daily. Generally, a 1kW solar power system will produce approximately 4kWh of electricity under ideal conditions.

Consequently, a 3kW – 4kW solar system would be required to cover your daily energy consumption. You would need a 5kW – 6kW solar system to be entirely off the grid.

However, it’s recommended by us to opt for a larger 5kW system. A 5kW solar system will cost around $4,500 – $8,000. Customers eligible for a government rebate could get a price reduction.

The main disadvantage of solar is that it only works when the sun shines. As a result, you’ll need to install a solar storage battery if you want to have power at night.

You may require a storage system of at least 10kW – this entirely depends on your energy consumption. Prices for a solar system of this size, including installation, can range between $8,000 and $12,000.

If you add up the solar system installation costs with disconnection and council permission fees, an off-grid solar system can cost around $20,000.

The cost of solar systems and storage batteries will soon be cheaper. If you cannot spend the money now, it may be worthwhile to invest in it soon.

Also, remember that you must maintain your solar system. And it might come with additional repair and replacement costs.

Will Living Off-Grid Save Money?

The short answer for the majority of you reading this is yes. But as appealing as it sounds, the initial investment might be a lot for average Australian households. However, with Solar Emporium’s solar packages and off-grid system, you can stop worrying.

Our packages and off-grid system bring inexpensive solutions to your doorsteps within a budget.

Should You Live Off-Grid?

Off-grid Living

Whether you should disconnect from the power grid depends entirely on your location and personal circumstances. You may get some fantastic deals on your solar installation. But it can take a long time to see a good ROI.

But grid electricity being costly, living off-grid may be a better option for average Australian households. Solar systems have grown in popularity in Australia over the last decade. An increase in solar ownership will decrease the cost of renewable energy.

Renewable energy sources are widely accepted as the way of the future. And as solar technologies improve, the capacity and efficiency of solar systems should improve while prices continue to fall.

Therefore, it will get more feasible for an average Australian household to live off-grid. It’s no surprise that many people in Australia are considering becoming more self-sufficient. And installing an off-grid solar system is the perfect way to do that.

Why Living Off-Grid Maybe Your Only Option?

  • If you live in a rural area of Australia without an electricity grid. You might be forced to create your electric systems. Hence, living off-grid may be your only option.
  • If you’re experiencing frequent blackouts, it may force you to disconnect from the grid.
  • The nearest grid connection point from your home is far away. And the electricity network wants to charge you an exorbitant fee to connect you to it.
  • Interested in self-sufficient energy without reliance on a grid or fossil fuels.

But Is Living Off-Grid Actually Possible?

Once off the grid, you can use a combination of storage solutions and technology. The best solution would be to reduce our reliance on the grid.

Solar PV technology makes the most sense because it has the quickest payback, especially if you can get a good deal on the panels.

We can all afford to reduce our dependence on the grid by simply using less energy. Our current energy use is highly inefficient, and we can change a few habits right now to make off-grid living more feasible and reduce our energy bill.

Living off-grid is the cheapest option for average Australian households. And as the fossil fuel industry faces the most dramatic change, off-grid living, and renewables are getting more feasible.

Step-By-Step Guide To Buying Quality Solar Panels In 2023

Step-By-Step Guide To Buying Quality Solar Panels In 2023

Have you decided to buy quality solar panels for your home to generate electricity? Then continue reading. Before purchasing, you should figure out how to choose the best solar panels specifically for your home.  

Our step-by-step guide to buying quality solar panels will give you every key point you need to know before going solar. This article also contains all the new updates of 2023! So look no further and review our article to get the best solar panels. 

Examine Your Electric Bill

Analyse your electricity bill before beginning the solar panel buying and installation process. You should get a consumption monitor for better results. It helps you determine your monthly energy consumption in kWh.  

In addition, it can assist you in selecting the solar system size that you need. To get an accurate estimate, look at the average monthly energy consumption over the last 12 months. 

Do A Technical And Feasibility Analysis

Conduct a study before installing your system. It can help you assess the structure of your building and determine the best products based on your energy consumption.  

The study will also assess the solar radiation patterns at your installation site. That will vary depending on your geographic location. Based on the study’s findings, technical experts can recommend the best equipment for your budget and energy goals. 

Because only buying quality solar panels is not feasible. The panels and mounting system have to comply with your house.  

Perform A Roof/site Inspection

Inspecting the installation site is critical to properly installing your solar panels. Look for a location correctly aligned with the sun. Because the best angle for solar panels will provide you with the ultimate solar energy. 

More importantly, look for a reasonable height and flat terrain.  

Examine for Compatibility

First, you must ensure your home is ready to receive a solar energy system. Determine whether your roof is large enough or has enough space to install the ground-level panels.  

Sometimes trees and branches are removed or trimmed. Your electrical panel may also require an upgrade. Verify if your roof is in good condition. 

Solar price varies

Choose a Size

Once you know your home is compatible, decide what services you want your system to provide. You can use the energy to power lighting or a few appliances. You can also choose a plan to generate energy for your entire house.  

You can even sell some power back to the grid through feed-in tariffs. 

Check For Permits

Apply for a building permit in your area. A separate electrical permit may also be required in some areas. Waiting for permits to be approved and scheduling subsequent inspections are frequently the most time-consuming aspects of a project. 

Apply for Incentive Programs

Take advantage of your solar investment. At the state and local levels, incentive programs differ. Federal incentives and schemes can also change from time to time.  

You may be entitled for tax credits, rebates, or grants from multiple sources to offset costs. Apply for these benefits before beginning the installation process. To finance the project, you could apply for a particular solar loan. 

Solar Price

So how much do solar panels cost? When comparing solar panels, this is the first-factor people consider. Several factors determine the cost of a solar panel. It includes the size, brand, quality, durability, and any certifications the solar panel may have. 

Price is an important factor when you are deciding on a solar panel. However, it should be one of many factors to consider because the cheapest panel may not be the most efficient. And in the long run, it may not be the best option.  

Solar panel selection can be challenging, but ensuring a quality solar panel system is more significant than going for the cheapest option.  

Check Solar Emporium’s Solar Packages for cheapest and the best panels 

Make a budget for yourself

Calculate the average cost of your solar energy system based on your monthly energy consumption. Also, get an estimation of the solar panel installation process costs. Consider warranties, maintenance costs, and the number of panels needed for installation. 

Quality of Solar Panels

This considers how the panel is manufactured and the quality of the materials used to construct the solar panel. Various manufacturers produce panels that vary in quality, price, and efficiency.  

Vertically integrated solar panel manufacturers control every stage of the manufacturing process.  

Many place a premium on quality and invest heavily in research and development (R&D). Other manufacturers assemble panels and usually do not manufacture their cells or support R&D. 

Energy Efficiency

The efficiency of a solar panel refers to how much the panel receives and converts into energy. And that’s you can determine the amount of power your system will generate.  

Sometimes the best option is to purchase the largest and most efficient solar panel. It may cost more but will save you money in the long run.  

Temperature Coefficient

It refers to the effect of heat on the operational efficiency of a solar panel. Because overheating of solar panels decreases their efficiency.

Durability

A 25-year warranty typically covers solar panels. If the manufacturer does not provide a long warranty period, you may suspect their product is subpar. Avoid being misled by an attractive price, as you may regret it in the long run. 

Of course, proper maintenance of your solar panels is essential to extend their lifespan. Fortunately, we have solar packages for brands that require less maintenance. 

Reduces Electricity bill

Where To Find The Best Solar Panel In Australia?

Prices vary significantly between companies. Therefore, finding the best solar supplier and installer may require requesting multiple quotes. Ultimately, the actual solar panel cost will depend on various factors. It includes-  
  • The solar panel’s type – monocrystalline, polycrystalline, or thin film 
  • How many solar panels do you require according to your house’s size 
  • The reputation of solar suppliers and installation companies  
  • Are the companies certified? What warranties do they offer? 
  • Each solar panel’s inverter type 

All the information and the renewable products should be available from the solar company you select to do business with. Remember, your solar installer should consider products based on your particular circumstances. They should provide the price quote accordingly.  

In addition, you should request to see any relevant industry-approved certification on solar panels and battery storage systems. You can trust Solar Emporium’s certificate and professionality without worrying.  

Installers of Solar Panels in Australia

With so many Clean Energy Council Approved Solar Retailers in Australia, finding the right solar panel installer should be simple. Visit the Clean Energy Council website to see a list of accredited retailers in your state. 

However, before signing agreements, confirm the Clean Energy Council website accreditation. It will definitely help you find which solar panels are best for you.  

Explore Your Specific Requirements

When buying quality solar panels in Australia, what you want and need are two different things. 

If you have a large family with many household appliances, a small solar PV system would not suffice. On the other hand, let’s assume you live alone in a small flat. Then there’s no point in going overboard with the panels. 

You must find your specific needs, and the system will work perfectly. And it will ultimately give you all the power you require while saving you money. 

You can see why doing your research is essential. Making an informed decision about your selected system will help you understand what will suit your needs.

Number Of Solar Panels And Batteries Needed For Aussie Homes

Number Of Solar Panels And Batteries Needed For Aussie Homes

When it comes to solar, there is no one solution. It is exactly like shopping for other necessary products that you need. Every person has different solar needs depending on many factors.  

So what is the number of solar panels and batteries needed for Aussie homes? To understand everything go through this Aussie batteries and solar review. 

For example, a 5kW solar system typically comes with 15-20 solar panels. It is usually sufficient for an average Australian home. Still, putting as many solar panels on your roof never hurts.  

However, the size of your solar system is determined by electricity usage, how much (unshaded) roof space you have, your budget, and a few other objectives. 

Getting solar panels is only worthwhile if you install enough to cover your electricity requirement. Similarly, you want to save money on a manageable solar system. 

How do you determine the number of solar panels and batteries you’ll need to power your home? 

How Much Power Do You Consume?

The goal is to match your household’s electricity consumption with solar energy. If not, then it may exceed a bit. Ideally, your solar system should produce enough electricity to meet your needs.  

Thinking ahead is critical. Ask yourself the hard questions. Will your family grow in the coming years? Are you considering purchasing an electric vehicle?  

How Much Roof Space Do You Have?

We can only fit as many solar panels as possible in the space on your roof. Solar panels are typically 1.7m × 1m in size. 

It is critical to consider shading when calculating the size of your roof. Tree or power lines can cast shade on a portion of your roof. In that case, we’ll need to adjust your solar system or avoid these areas entirely.

How Much Money Do You Want To Spend?

The larger the solar system, the higher the cost. As a result, the size of your solar system will be determined by your budget.  

Like any other product, budget solar panels are less expensive than tier 1 panels. However, it is never worth sacrificing quality for lower-cost solar panels.  

A solar system is a 25-year or more long-term investment. Purchasing quality solar panels that will last for a long time should not be negotiable. 

Find more information about the payback period for a solar system here. 

What is Your Primary Goal in Installing Solar Panels?

Solar energy abstract concept vector illustration.

Some people purchase solar panels primarily to save money. Others are motivated by the wish to become more energy independent or by environmental concerns.  

Your motivation for going solar may influence the number of panels you require. For example, invest in a more extensive solar system to be self-sufficient. And you’ll also need a battery to use solar power all day and night.

Compare Panel Efficiency and Types

Solar PV is classified into monocrystalline, polycrystalline, and thin film. Each has a different efficiency rating as well as a different price point. You need to consider which solar panel system has high efficiency. 

Monocrystalline cells are the most efficient because they are made from large silicon crystals. They are also more expensive. 

Polycrystalline cells are made using silicone moulds. Therefore, it is less expensive. But also slightly less effective than monocrystalline cells.  

Thin film panels are inexpensive but much less efficient than other types. 

Before purchasing a solar power system, inquire with your installer about the solar panels’ life cycle and efficiency. Check the warranty to ensure a plan that will last many years. 

Understand Your Battery Storage Options

Solar PV systems generate the most amount of energy during the day. Consider solar battery storage if you spend most of your day at work. Solar batteries enable you to store energy generated during the day when the sun isn’t shining. 

The battery capacity is measured in kilowatt-hours (kWh). If 60% of your energy consumption occurs at night, you may want a battery to store that amount. 

However, solar battery storage can be costly, so consider a feed-in tariff system to get the money back.  

Lifestyle changes can help reduce your nighttime energy usage. For inspiration, check out our guide on how to get the most out of solar. 

How Many Batteries Will You Require?

This is an interesting question. Solar batteries for homes actually depend on your goals for your solar batteries. Most people set out to reduce their grid electricity imports to zero.  

As you’ll see, most households have big energy storage goals with more expenses. But how many solar panels run a house? “What size solar battery do I need” is a natural question you ask yourself.  

Let’s go over how much energy storage an average Australian household will require. 

The average Australian home consumes approximately 16kWh of electricity per day. Please read this if you need clarification on the difference between a kW and a kWh – it is critical). 

Most Australians work 9 to 5 jobs and are not at home during the day. They will probably only use about 30% of their electricity when the sun shines.  

That means they must buy the remaining 70% from the grid. How many solar batteries will be required to cover that 70%? 

Solar Battery System Sizing

Regarding system sizing, battery sizes are measured in kilowatt-hours, or kWh. 

As mentioned before, an average home consumes 16kWh of energy. And 30% of the energy is consumed in the daytime and 70% at night. That mounts up to approximately 5kWh consumed during the day and 11kWh consumed at night. 

Based on simple maths, the average Australian would require approximately 11kWh of solar battery storage to offset all their night usage. 

As of February 2023, the Tesla Powerwall 2 has a capacity of 13.5kWh, costing around $16,600 fully installed.  

Remember that you do not need batteries to offset your nighttime electricity consumption. If you run the numbers, the first kWh of energy storage has the best payback because it works the hardest. As of the next kWh, the payback becomes longer.  

However, the most important consideration when sizing and comparing solar batteries is that it is only possible when you thoroughly understand your energy usage profile. First, you’ll need a good energy monitor in your home with accurate data. 

Then, a good installer will use their software to show you the optimal number of batteries and solar panels for your situation and the payback period. After that, instead of leaping into the unknown, you’ll go into your solar battery investment with your eyes wide open.

What If Every House In Australia Has Solar Panels?

What If Every House In Australia Has Solar Panels?

Every day, the sun emits far more energy to run the planet. Solar panels convert the power of the sun into electricity. It is essential to decarbonise our society. Solar power is a renewable energy that doesn’t create any co2 emissions. Every day solar panels for house usage are getting popular.  

Rooftop solar power is on its way to becoming Australia’s leading source of power generation capacity. So what if every house in Australia has solar panels? What would be the scenario? How would it benefit the country’s population?  

Rooftop solar panels generate approximately 20 gigatonnes (GW) of power in Australia. And over 3.3 million households have solar PV installed on their rooftops.  

Because of Australia’s land and sunny weather, it would be a significant benefit if every house had solar panels. Household battery storage will become more valuable than grid power.  

How Can Solar Benefit Every Household In Australia?

Almost 40% of the roof space is already eligible for a solar system. According to data, solar power station conversion is possible on most rooftops. And approximately 134% of the country’s residential electricity needs should meet this number.  

These massive levels of solar installation would benefit jobs. But it is also financially feasible because Solar has never been more affordable. New financing plans, such as “Energy Matters and Save as You Go Solar,” make owning a PV system very affordable.   

One of these new offers is a no-deposit payment plan. It will help with your electricity bill to pay off your solar loan. 

On a sunny day, baseload power stations could be considered redundant. That allows Australia to shut down most of its coal-fired power plants overnight. Simply closing coal power plants can progress towards our emissions targets almost immediately. 

The overarching concept is for eligible homes to generate more electricity than required. The excess supply is fed back into the grid to meet Australia’s residential and non-residential power needs. And with feed-in tariffs, solar panel users can earn their money back.  

Above all, Solar is a viable solution to Australia’s energy challenges. And it would permanently reduce the country’s dependence on expensive fossil fuels to generate electricity. 

But How Is the Progress?

solar panels will cover every roof

Border closures and supply chain disruptions caused by COVID-19 did not slow Australia’s massive uptake of rooftop solar. Installation reached record amounts last year.  

According to the Clean Energy Regulator (CER), over 3,000MW of small-scale solar was added to grids on December 31. It surpassed the previous high of 2,964MW in 2020. 

South Australia has led the country in rooftop solar power for a long time. However, Queensland has surpassed it, with 82% of roofs deemed suitable for solar PV. South Australia has a figure of 78%, so the state can reclaim the lead. Solar PV in New South Wales and Victoria has reached 51% and 43%, respectively.  

The numbers speak for themselves. Australia’s solar capacity was increased by 20% in 2022. Many projects toward renewable energy and the Russia-Ukraine crisis have made Australia more proactive.  

Even though the residential PV market had drawbacks in 2022, the large-scale solar market had a record year. Installations increased compared to 2021 installations.  

Another 10 GW is expected to be installed within the next three years. Rooftop solar PV alone will soon outnumber coal power capacity. And soon, the government may decommission many coal power plants.    

Can Solar Alone Help You With Consumption & Distribution?

Your PV system is made up of various components. Depending on your chosen system, several panels will be mounted on your roof. Your expert installer should install mounting equipment and an inverter too.  

More advanced systems include performance monitoring equipment and a rechargeable battery if you have a solar-plus-storage system. Solar-plus-storage systems include a solar battery to store any excess energy. And later, it can provide you with stored energy. 

Do you want to learn more about solar and batteries? And solar system for house usage? Then contact us or request a free quote. We’d be delighted to discuss the best solar power and battery options for you.  

Most of the work is done by your solar panels. It absorbs photons from the sun’s rays and converts them to DC, or Direct Current energy. An inverter converts your panels’ direct current (DC) energy into alternating current (AC) that household appliances can use. 

Performance monitoring equipment can help you track how much energy your system produces. And identify any faults to ensure your system is operating at peak efficiency. This advanced system can even feed data to a program accessible via the Internet or a mobile app. 

Solar panels generate the majority of their energy during the day when we are away from home to use them. When your system generates more energy than it consumes, the excess energy is returned to the grid. And to charge your battery. 

Any excess energy generated will be fed back into the grid when your battery is fully charged. The majority of solar-powered homes are net-metered. Any energy you send back to the grid will earn you a ‘feed-in-tariff. That can be applied to the cost of any grid energy you use. 

What Should You Do Before Getting Solar?

  • Consider your current electricity consumption. You can use a recent energy bill to check your energy usage. It can estimate your electricity usage based on your area and household size. 
  • Select the appropriate system size for your needs. Consider every future requirement. Your energy retailer may assist you with the information. 
  • Understand the numbers. Determine whether you are eligible for any incentives or rebates. Calculate the payback period, and discuss the tariff and small-scale technology certificates (STCs) with your retailer. And most importantly, consider how solar energy will affect your current electricity rate. 
  • Check to see if your solar company is an Approved Solar Retailer. Choose Retailers approved by the Clean Energy Council’s Solar Retailer Code of Conduct. This code mandates that they provide you with clear, accurate information and service. 
  • Check that your solar retailer can provide evidence that your new solar panels are genuine. Meet Australian Standards, and have a warranty you can rely on. 
  • The Clean Energy Council’s Buying Solar guide provides technical information to help you decide on the best solar system.  

Many countries were reluctant to the concept of a green future. But we are already here. Independence from the grid allows people to go entirely off-grid. 

Solar Emporium’s job is to make your path toward renewable energy stronger. And our exclusive solar packages will surely excite you to go solar. Solar power in Australia has become more common so being a part of this revolution will only benefit you.

Common Problems With Solar Panels In Australia

Common Problems With Solar Panels In Australia

Solar panels are among the best investments to create a sustainable environment and empower positive change. Solar panels require little maintenance and save money on energy bills. 

But problems with any product can arise anytime. Thus, to make everyone aware, we’ve compiled this helpful guide that shows you common issues with solar panels in Australia and how to fix them. 

Australia receives the most solar energy in the world. And it is an ideal location for developing solar energy infrastructure. As a result, more people are getting with the times and doing their part to save the world by installing solar panels in their homes. 

As a result, more people are installing solar panels to participate in the renewable energy revolution. But like all technology, solar has some flaws too. While you can resolve some of those issues on your own, others may require the services of a solar repair company. 

The key is identifying your issue and deciding how to fix it. Here is a guide to Australia’s most common solar panel problems. And don’t worry. We’ll definitely provide information to help you resolve the issues. 

Grime And Dirt

A buildup of dirt or grime is one of the most common reasons your solar panels aren’t performing as well as they should. Solar panels are vulnerable to dust, dirt, and other debris like other products.  

Mainly flat roof-mounted panels are more susceptible. Since they are flat, they naturally collect more grime, which can reduce system output. This can have an impact on the efficiency of your panels. 

Dust, bird droppings, leaves, and ash from nearby fires are all common problems.  

Birds

Birds can actually create issues for solar panels. They can build nests beneath solar panels that are mounted on the roof. If they become frequent to your panels, they will probably scratch or damage the wiring. 

Potential Induced Degradation

If you’ve noticed a significant drop in the electricity produced by your solar panels, it could be due to the PID effect or Potential Induced Degradation. 

This indicates a voltage difference between the solar panel and the earthing, which causes a partial voltage discharge. Essentially, you’re losing voltage and potentially jeopardising the long-term effectiveness of your panels. 

Problems With Your Inverter

Better inverter for better outout

Solar inverters are critical in converting direct current (DC) energy from your solar panels to alternating current (AC) energy used by your home. As a crucial system component, you will undoubtedly detect any problems. 

Although inverter technology has advanced, inverters typically only last for a short time as your panels. And if you don’t replace the inverter in 15 years and wait for 25 years, it will compromise the productivity of your solar panels.  

Snail Trails

Another common issue with solar panels is called snail trail contamination. The name derived from the brown lines on your panels and gives the impression that snails have walked on the surface. 

Snail trails usually appear after a few years and are caused by various factors, including faulty silver paste. Microscopic cracks in the PV system can also cause snail trail contamination. The issue reduces the solar system’s performance and causes it to fail prematurely. 

Micro-cracks

Traditional solar cells are incredibly fragile. Micro-cracks are small cracks that can appear on panels and are challenging to see with the naked eye. However, these cracks can enlarge and become more visible with time and significant weather changes.  

When these cracks grow larger, they can disrupt the flow of energy in your panel and reduce the energy output of your system.   

They can occur during conventional PV module production but can also be caused by careless handling during shipping or installation. Sometimes weather conditions can cause micro-cracks too.  

Solar Panel Electrical Wiring Issues

Faulty or even old electrical wiring on your roof will prevent your solar panels from performing efficiently because it will interfere with electricity production.  

It’s natural for your roof’s electrical wiring to deteriorate over time due to loose connections, corrosion, and oxidation.  

Furthermore, rats can cause damage by chewing on the wiring. If left unattended, these electrical issues can cause problems with your roof. In the worst-case scenario, they can even set fire to your roof.  

Corrosion

Your panels are exposed to harsh Australian conditions. It includes heat and heavy rain. Moisture may leak into your panels over time. As a result, it will trigger a corrosion process.  

If the panels corrode inside the bus bars, it’ll cause the system to shut down due to isolation. Unfortunately, the panels will be beyond repair.  

Solar Panels With Hot Spots

When the panel’s energy cannot flow through to your inverter, it becomes overloaded and radiates excess heat, so they get hot. It is one of the most common issues with solar panels worldwide.  

Hot spots can reduce the performance and lifespan of your solar panels. They are caused by various factors, such as dirt or bird-dropping accumulation, partial shading, and even structural defects. 

Roof Defects

The installation of solar panels should not cause significant damage to the roof beneath. Instead, they occasionally provide some protection for the materials beneath. However, sometimes it can loosen or damage tiles. 

How to Know Your Solar Panels Aren't Functioning Properly?

There are some questions to check to know whether your solar panels are performing well. 
  • Is your electric bill higher than usual? 
  • Are your panels visibly dirty or in direct sunlight? 
  • Are there any error codes on your inverter? 
  • Is there any unusual data in your system’s analytical tools? 
  • Is your average daily kilowatt-hours metric on the decline?

  • Ensure that any professional you contact is registered on the Clean Energy Council’s installer list. It guarantees that they have agreed to uphold high standards. And they are obliged to serve you if something goes wrong.  
  • Clean your panels at least once every 12 months. Rain may do a lot of the work for you. But cleaning the panels will prevent dirt or grime from piling up.   
  • If the solar panels are accessible, simply clean them with warm, soapy water free of harsh chemicals.  
  • You can also take precautions by installing mesh wire or other bird deterrents during installation. There are ways to keep birds from nesting beneath our solar panels without harming them. 
  • Most modern inverters have displays that show any occurring errors. Always compare the error messages to your user manual. It should be pretty simple to figure out what’s wrong.  
  • Always check for any blackout, as it is one of the most common inverter problems. The breaker may have been automatically turned off.  
  • When installing solar panels on your roofs, you must always buy from a reputed company with the highest quality and testing standards.   
  • Checking on your roof occasionally can mitigate the risks of any wiring issue. Contacting your PV system installers is the best option if you find any problems. 
  • Maintain the perfect shading system.  
  • Some problems aren’t visible to the naked eye. So if you suspect any situation, you must contact your trusted solar professionals to inspect it. 
  • Contact a pest control professional if you notice nests or birds dropping on your panels.

Can Solar Help Cut The Living Cost In Australia In 2023?

Can Solar Help Cut The Living Cost In Australia In 2023

Unsurprisingly, electricity prices are Australia’s top cost of living concern. Our power bills are among the highest in the world! Most Australians believe energy costs are their primary source of stress.  

So the big question is, Can solar help cut the living cost in Australia in 2023? And can solar energy help Australians relieve energy bill stress? 

Every day more and more Australian households are struggling to pay their electricity bills. Some reports indicate that families even choose to move houses! They are also discarding their belongings and appliances. Some even start living off the grid to reduce the cost.  

Despite the abundance of solar energy available in Australia, the current rate of solar energy distribution needs to be improved. The Australian government launched several renewable energy policies to encourage the country’s accelerated adoption of solar energy.  

Their goal is to develop the national renewable energy target. These solar-related policies can eventually cut the living cost in 2023. The primary policies are (i) state feed-in tariffs (FITs); (ii) solar rebates and incentives; and (iii) Renewable Energy Certificates. (RECs). 

Feed-in-Tariffs

The Feed-in Tariff is another Australian subsidy for solar-powered households. Anyone with a grid-connected solar installation can benefit from these cost savings. 

The majority of household solar systems will be linked to the power grid. Unless you live off-grid, any excess solar power generated by your solar panels is fed back into the grid. 

That means power companies will pay you for the solar electricity your system exports to the grid. 

Using a solar calculator, you can estimate how much power your house consumes and how much excess energy can go back into the grid. 

The solar feed-in tariff, or the “buyback rate,” is the amount paid per kilowatt-hour of solar electricity exported to the grid from your solar system. Most Australian electricity retailers will now offer competitive feed-in tariffs within their standard product range. 

The program is also separate from the STC program. The STC program and state incentives typically assist homeowners with only the initial installation costs of solar installations. It can provide financial benefits for the life of your PV system. 

Rebates and Incentives

Renewable energy target with solar

The Australian Federal Government provides federal financial incentives in most parts of the nation. These tax breaks encourage the installation of small-scale renewable energy devices. Solar, wind, and hydro are examples of small-scale renewable energy sources.  

And solar photovoltaic (PV) panels are the simplest and most accessible choice for the average homeowner to install in their home. 

Homeowners or small business owners can qualify for financial assistance through the Small-scale Renewable Energy Scheme (SRES). 

After that, you will get the small-scale Technology Certificates (STCs). These STCs have a monetary value that can be redeemed when sold or assigned. More STCS may be granted to some installations. Two factors determine your chances of getting STCs-  

  • How much electricity is your system produces.  
  • And the weather of the area you installed your system. 

The STC program is a government-run scheme. It compels others to purchase your STC certificates.  

The Australian Federal Government scheme will subsidize solar systems starting in May 2021 at around $525 per kW installed. This subsidy will save you approximately $3,465 on a typical 6.6kW solar power system. 

Rebates are typically applied at the point of sale when you purchase a system. As a result, advertised solar panels and kits prices will likely include the solar rebate. 

Solar energy can benefit every Australian. Subsidies and other forms of assistance should tailor to individual needs. Hence, the Austral Federal Government also has some incentive programs across states.  

The New South Wales Government has a solar power incentive called the Empowering Homes program. The Victorian government also provides incentives for homeowners, known as the Solar Homes program. 

These schemes provide a financial incentive for ordinary Australians to install small-scale solar systems, solar water heaters, and heat pumps. Many other renewable energy schemes and incentives are available in different states.  

Renewable Energy Certificates

Both large-scale power plants and small-scale system owners can apply for Renewable Energy Certificates.  

Retailers should submit the certificate to Clean Energy Regulator to meet their legal responsibility under the Renewable Energy Target. It also creates an opportunity for system owners to receive financial incentives. 

Energy certificates can provide customers with fair prices for installation and energy bills.  

But What About Solar Equity?

Solar will relieve from energy bill stress

Renewable energy is critical for lowering energy bills, mitigating climate change, and promoting sustainable development. However, access to solar power is only equitable for some Australians. 

Due to the high upfront costs, many people need help installing energy-saving options such as solar panels or insulation. A large majority of those who are financially stressed earn less than A$50,000.  

And people between 18 and 34 do not intend to install energy-saving options for lack of funds. 

What policies Can Help Increase Solar Equity?

Among existing policies, some other steps can help improve equity in rooftop solar access-  

  • Direct financial assistance for low-income households  
  • Variety of other financial incentives and solar rebates  
  • Community solar programs with households to share the benefits. 

Some programs are already in place to assist low-income homeowners in installing solar systems. New South Wales has a “Solar for low-income households” program.  

Individuals who qualify can receive a free 3-kilowatt solar system for the previous Low-Income Household Rebate for ten years.  

Enjoy the Power of the Sun With Less Energy Bills

The Renewable Energy Target in Australia has implemented energy schemes to ensure solar equity to cut living costs for consumers of Australia. And as solar panel prices are slowly dropping, the perfect time to invest in solar energy.  

Be a part of the solution and join the thousands of Australians who benefit from solar energy. 

  • Decrease your electricity bills dramatically so that you can focus on more important things.  
  • Reduce your carbon footprint and contribute to renewable energy targets.  
  • Generate clean power for your home or business without blowing up your savings.  
  • Increase the value of your home or business.  

Because of the increasing global attention to greenhouse gases, it is inevitable to transition to renewable energy sources such as solar. 

Australia is one of the world’s largest energy consumers and has favorable environmental conditions for solar technology distribution. Get a free quote from Solar Emporium for solar panels to avail these benefits.

Do Aesthetics Matter For Solar Panels?

Do Aesthetics Matter For Solar Panels

According to the majority of Australians, the aesthetics of solar panels have previously discouraged them from going solar.  

Homeowners are often well aware of the environmental benefits of solar photovoltaic (PV) panels. Still, the decision to go solar is frequently interrupted by the fear of ruining the aesthetics of a home.  

So do aesthetics matter for solar panels? Do customers actually care about the appearance of their solar panels? 

Well, solar panels’ aesthetics are essential because they are very evident and noticeable to the owners. These are usually mounted in prominent locations where people can see the displayed panels. 

In a recent study, many respondents were shown various panel images. They were shown the panels alone and panels on roofs. The findings showed consumers prefer black panels with rounded corners and even-surfaced cells. They are also willing to pay more for a more aesthetically pleasing system.  

The results were even more impressive when respondents saw panels on a roof, rather than just pictures of the panels. Contextualized images made the difference. 

Appearance is important to homeowners. So much so, that they are willing to forgo performance for a better-looking solution. This is the most significant takeaway from this study. These findings believe that aesthetics are a crucial selling point for homeowners.  

Another critical takeaway for installers is the significance of visuals. In fact, the visual presentation can influence a homeowner’s opinion of solar in general. 

Today’s markets offer many options to maintain the look of solar panels and the buildings they are mounted on. Additionally, future markets will offer similar options.  

Performance, rather than aesthetics, has traditionally influenced PV system design. But as the desire for appealing solar panels are growing. And many creative solar companies and architects are designing systems to complement the building.  

Some technology includes making panels totally invisible! There are mainly two ways of making the panels discreet. a) placing them on the rear end of the roof and b) combining them as an architectural structure.  

The PV panels can be integrated into the building, providing views through the panels, shade, and rain protection. Conventional building materials, such as roof skylights, can be incorporated with solar cells, lowering the cost of going solar.  

And the initial cost can be balanced by reducing the amount spent on building materials and labor to construct. This also allows the designer to be creative and fully integrate the PV system into the building’s architecture and construction. 

Other options may include thin black film panels with black anodized mounting systems or powder-coated after production. All black designs are more eye-catching than blue ones. And these almost look like the roof, making them more aesthetically pleasing. 

PV panels will become not only more efficient but also more aesthetically pleasing in the future. Meanwhile, several strategies are already in process to increase the appearance of solar panels. 

Solar Panel Mounting Systems

Panels' mounting system is very important for aesthetic looks

Solar panels’ aesthetic doesn’t just depend on the solar panel type. How installers mount your solar panels can also determine the aesthetical look of your house. This part of the article will explore how solar panel mounting systems can be aesthetically different. We will look at the following: 

  • On-roof mounting system – This is the standard and most common mounting system. The solar panels are mounted on a frame fixed slightly above the roof’s surface with the on-roof mounting method. It is a cheaper and faster system to integrate solar panels on an existing rooftop.  
  • In-roof mounting system – This is also known as a roof-integrated or semi-integrated mounting system. In-roof mounting systems use solar panels and a frame system to create a watertight roof covering. This means the solar panels are much lower on the roof and appear more discreet. This looks especially pleasing with an all-black solar panel. 
  • Freestanding mounting systems – Freestanding solar panel systems are not attached to a pitched roof structure like other systems. Solar panels are commonly used on flat roofs or in ground-mount systems. The angle of the solar panels is adjusted to maximize the amount of solar energy they produce. Depending on how you position the panels, the aesthetic value increases. 

Solar Panel System Aesthetics Types

Different type of solar panel indicates different level of aesthetics. There are five types of aesthetics available for home solar arrays:
Silver Frame – When homeowners express dissatisfaction with the appearance of panels, they may recall the traditional solar panels. This design isn’t going away anytime soon because it’s the most cost-effective configuration. They also have a sizable market among utility providers and other commercial customers. Lower price points and higher efficiency due to better heat regulation from contrasting colors make these panels desirable. 
Black panels are sleeker and smoother
Black Frame – The silver aluminum frame replaced with a sleeker, fitted frame. The white backing and lifted racking keep the system cool and efficient. It is definitely more appealing but generally comes with a slight price increase.  
Black on White panels are very popular
Black on White Frame – Adding a hidden wire component to this sleeker design makes this panel’s style more versatile. It can close the gap between the surface and the panel. Less expansion out of the roof could result in less infrastructure on your rooftop. That will potentially lower installation costs while adding aesthetic value. 
Black on Black – This design is the first actual all-black panel. It completely conceals the white backing. But because of increased heat absorption, these panels are less efficient. But this sleek design fully encompasses a modern look from a distance. 
Advanced Black on Black panels are efficient and sleek
Advanced Black on Black – SunPower has enabled this technology with a tinted window appearance while maintaining industry-standard efficiency. This high-performance black panel combines design and utility by incorporating long-lasting, non-toxic materials.
BIPVs are an architectural advanced technology

Building Integrated Photovoltaics (BIPV)– It is a type of solar technology. It replaces traditional building materials such as glass or external cladding. Using BIPV to design buildings makes the solar element more subtle. Because BIPV projects are much more customized than standard solar panel installations, the design phase is much more critical. 

Solar Tiles – Solar tiles are roof tiles that incorporate solar photovoltaic cells. The tiles are strung together to create a solar array like standard solar panels. The aesthetics of solar tiles over traditional solar panels are their primary advantage. These can be very discrete and blend into the building and surrounding environment.
