6 Ways Solar Panels Help Save Water

6 Ways solar Panels Help Save Water

As corporations and individuals increasingly prioritise environmental responsibility and seek innovative ways to conserve energy, solar power is gaining widespread popularity for various reasons.  

Beyond the cost savings on electricity, it proves to be both more efficient and environmentally friendly. And we have found 6 ways solar panels help save water.  

Unlike traditional power sources such as coal, natural gas, or nuclear energy, solar panels directly harness electricity from sunlight. It eliminates the need for water in the generation process.  

In contrast to power plants that rely on significant water consumption for cooling and steam production.  

So what are the 6 ways solar panels help save water? Let’s find out.

Water Reservation

Solar energy contributes to water conservation by fundamentally minimising its water requirements. Compared to coal mining and gas extraction, solar energy operations are notably less water-dependent.  

Traditional methods, such as coal mining plants and hydraulic fracking operations, consume staggering amounts of water daily during production. Millions of gallons of water are utilised in these processes, leading to significant environmental concerns. 

The distinctive advantage of solar panels lies in their ability to generate energy without any need for water.  

Unlike their counterparts, solar energy systems bypass the consumption of water during electricity generation. This contrast makes the substantial volume of water used in coal mining and fracking operations appear disproportionately excessive.  

Moreover, the water utilised in these traditional processes often becomes contaminated, exacerbating environmental challenges. 

In essence, solar energy provides a sustainable and clean source of power but also plays a crucial role in conserving water resources.  

By eliminating the substantial water demands associated with conventional energy production methods, solar energy contributes to a more environmentally responsible and water-efficient energy landscape.

Solar Panels Require No water to Generate Electricity

Solar panels require zero water for power generation, a stark contrast to conventional electric power plants that heavily rely on substantial water quantities for their cooling processes.  

Power plants account for 45 per cent of total water withdrawals, 38 per cent of total freshwater withdrawals, and 51 per cent of fresh surface-water withdrawals across all applications. 

In contrast, solar panels operate without the need for cooling mechanisms and, consequently, without water needs.  

A report from the International Renewable Energy Agency (IRENA) highlights that the water consumption for producing a unit of electricity using solar panels is as minimal as 1/200th of that used by a typical power plant.  

Illustrating the significant impact of solar energy on water conservation, Solar Emporium’s solar panel systems were proven successful in a short period.

Solar Panel Production Takes Less Water

Although the production of solar panels involves some water usage, ongoing advancements in efficiency and recycling are progressively reducing their water intensity.  

Like any industrial process, the manufacturing of solar panels incorporates water, but employing intelligent methods in industrial production—such as enhanced efficiency and recycling practices—can significantly mitigate the water footprint and environmental effects.  

For instance, Solar Emporium anticipates that many newly established solar panel manufacturing facilities will achieve a 70% water recycling rate once fully operational. Notably, water recycling and efficiency measures have contributed to a remarkable 43% reduction in water consumption over four years.  

Both wind and solar panel technologies exhibit remarkably low water usage. These panels operate without any water consumption throughout their operational lifespan.

Charging Electric Vehicles Uses Less Water

electric cars

Utilising solar panels to power an electric vehicle results in lower water consumption compared to fuelling a car with petrol or biofuels. Opting for solar power minimises your water footprint and also extends these water-saving benefits to your journeys on the road.  

Solar power generation possesses a relatively modest lifecycle water footprint, making the operation of an electric car powered by solar panels notably water-efficient, especially when contrasted with petrol—an oil-derived fuel predominant in contemporary vehicles. 

Similar to coal and natural gas, the extraction, and processing of oil demand substantial water resources.  

Liquid biofuels, such as ethanol, also contribute to significant water usage in the cultivation and processing of energy crops. Our calculations indicate that producing a single gallon of corn-based ethanol may entail over two hundred gallons of water consumption. 

For individuals conscious of water conservation, opting for a solar-powered electric vehicle emerges as a prudent choice in promoting water savings.

Floating Solar Panel Saving More Water Than We Think

The adoption of floating solar panels, also known as “floatovoltaics,” is gaining popularity globally, extending from Napa to Japan.  

These innovative solar farms strategically placed on reservoirs and large water bodies contribute to the generation of clean power and also offer an additional environmental benefit by curbing evaporation.  

This approach has been demonstrated effectively in various locations, such as a vineyard in Napa that installed floating panels on an irrigation reservoir.  

Beyond providing power to the vineyard, this initiative remarkably reduced evaporation by an impressive 70%. 

The significance of this water-saving aspect becomes apparent when considering the potential impact of uncontrolled evaporation on bodies of freshwater.  

By partially covering water surfaces with floating solar panels, not only is clean energy generation increased, but the reduction in evaporation also helps in mitigating the losses of freshwater resources.  

This dual benefit underscores the potential of floatovoltaics as an innovative and environmentally sustainable solution to both energy generation and water conservation challenges.

Water Management and Maintenance Through Solar Panels

Solar panels play a crucial role in enhancing water management and efficiency for local water districts. A significant portion of the operating budget for water utilities, particularly those involved in treating drinking water, is allocated to energy expenses.  

It not only aids in reducing energy costs but also contributes to the preservation and enhancement of water resources in several ways. 

Firstly, water facilities powered by solar energy alleviate the reliance on electricity from water-intensive power plants, thus reducing the overall demand for water resources for energy production. 

Secondly, by cutting down on energy expenses through solar energy adoption, water utilities can redirect resources towards endeavours that enhance water efficiency and incorporate advanced water technology.  

This positive development benefits all water consumers, as it enables the implementation of measures geared towards improved water management and the integration of state-of-the-art technologies in water treatment facilities.

How Do Solar Eclipses Affect Solar Energy

How Solar Eclipses Affect Solar Energy

On April 20, 2023, Australia and parts of Southeast Asia experienced an extraordinary solar eclipse that has captivated the interest of both solar and weather enthusiasts.  

This occurrence is a unique hybrid solar eclipse. It is a rare celestial event that alternates between an annular and a total solar eclipse along its trajectory.  

So, what are eclipses? And how do solar eclipses affect solar energy?  

In specific regions, observers witnessed a total solar eclipse. In contrast, others observed an annular solar eclipse characterised by the Moon partially concealing the Sun and creating a visible “ring of fire.” 

Here at Solar Emporium, we are enthusiastic about this rare celestial phenomenon. Not only does it provide a spectacular demonstration of the vastness of celestial bodies, but it also has implications for the irradiance levels throughout the day.  

This blog post will explore the scientific aspects of hybrid solar eclipses. We will elaborate on how solar eclipses impact solar energy. And discuss solar irradiance and the potential ramifications for the power grid in Australia.

What is A Solar Eclipse, and How Often Do They Happen?

A solar eclipse happens when a new moon lines up perfectly between the Earth and the sun, creating a shadow on our planet called an umbra.  

The moon’s size and distance from Earth make it big enough to cover the sun’s disk, partially or entirely, depending on the distance between these three celestial bodies. 

On average, a total eclipse, where the moon completely blocks the sun, occurs approximately every one or two years.  

Partial solar eclipses happen more frequently when the moon covers only part of the sun. 

There are other eclipses, such as annual eclipses. It’s an eclipse with a circle of light around the moon. And there are rare hybrid eclipses, where an eclipse changes from annular to total. Annual eclipses happen because the moon’s orbit around the Earth is not a perfect circle, so its distance varies with each orbital cycle.

Understanding Solar Energy

solar energy

Solar energy is a power source that comes from the Sun. Typically, the Sun’s light reaches the Earth, and we use that light to generate electricity through solar panels.  

However, during a solar eclipse, the Moon moves between the Earth and the Sun, blocking some sunlight for a little while. 

This temporary blockage affects solar power generation. When the Moon covers part of the Sun, less sunlight reaches solar panels on Earth.  

It means they produce less electricity during the eclipse. It’s like a brief dimming of the Sun’s power. 

In places where solar power is a big part of the energy supply, like in Australia, this reduction in sunlight during an eclipse can impact the amount of electricity generated.  

However, experts usually plan for this and have ways to manage it. They might use other power sources or have backup plans to ensure enough electricity for everyone. 

A solar eclipse is like an interruption in the usual flow of solar energy, but it’s something that energy experts can handle to keep our power supply stable.

How Solar Eclipses Affect Irradiance

Solar eclipses occur when the Moon comes between the Earth and the Sun. It temporarily blocks a portion of the Sun’s light.  

When there’s an eclipse, the sunlight from space, called extraterrestrial irradiance, gets less because the Moon covers part of the Sun.  

This reduced sunlight goes through the air and clouds, making even less sunlight reach the Earth’s surface during the eclipse. So, there’s not as much solar energy during that time. 

The connection between solar eclipses and irradiance appears straightforward until atmospheric conditions and calculations are considered.

How Do We Figure Out the Impact on Solar Power When Solar Eclipses Occur?

To understand how a solar eclipse affects sunlight, we must predict which part of the Sun will be covered. We do this by observing where the Sun and Moon are in the sky from a specific location.  

We then figure out how much they overlap. Checking the area of the Sun and Moon for every single question would take a lot of computing power.  

So, we focus on the time and places impacted by the eclipse. This way, we can quickly answer questions for all our users. 

This approach needs a model that can calculate where the Sun and Moon are based on a person’s latitude and longitude. The model uses algorithms that consider the tilt of the Earth’s orbit, the shape of its path, and how its axis moves over time.

How Did the Eclipse Affect the Power Grid?

When there’s a solar eclipse, it reduces the amount of sunlight. This year’s eclipse also affected solar energy generation, especially in Western Australia.  

Since solar energy decreases during the eclipse, the grid must compensate for this temporary loss.  

Knowing and predicting how much this will impact the power grid is essential for energy providers and operators to keep the power supply stable and reliable.  

Because there’s less solar power during the eclipse, grid operators and energy providers should prepare for extra strain on regular power plants or energy storage systems.  

Making accurate predictions about how the eclipse will affect solar power helps these companies plan how to manage energy and avoid any problems with the power supply. 

This temporary drop in solar power shows why having different types of energy and sound energy storage is essential.  

Using various renewable energy sources, like wind, hydropower, and good solar batteries, grid operators can ensure the power supply stays reliable and steady during events like solar eclipses.  

Having accurate forecasts about drops in sunlight, whether because of the weather or events in space like an eclipse, is crucial for operators of solar battery storage systems.  

It helps them understand how much energy to expect from renewable energy sources.

Solar Battery Storage Plays an Important Role During a Solar Eclipse

Battery storage plays a crucial role when a solar eclipse occurs. During a solar eclipse, the Moon moves between the Earth and the Sun, temporarily reducing or blocking sunlight.  

This reduction in sunlight affects solar power generation, decreasing electricity production from solar panels.  

Battery storage systems become particularly important to maintain a stable power supply during this period. 

Here’s how battery storage helps during a solar eclipse:

1. Energy Storage:

Batteries store excess energy generated by solar panels when the sun is shining. Leading up to a solar eclipse, battery energy can be kept to ensure a continuous power supply when solar production is temporarily reduced.

2. Grid Stability:

Battery storage systems stabilise the grid by releasing stored energy when solar power decreases. This helps balance the electricity demand and supply, preventing disruptions in the power grid during the eclipse.

3. Smooth Transition:

As the eclipse progresses and solar energy decreases, battery storage can seamlessly take over, providing a consistent power output. This prevents sudden drops in electricity supply, maintaining reliability for consumers.

4. Backup Power:

Battery storage is a backup power source during the eclipse for areas heavily reliant on solar energy. It ensures that essential services and critical infrastructure continue to receive power, even when solar generation is limited. 

5. Load Management:

Solar battery systems can strategically manage energy loads during the eclipse. By releasing stored energy during peak demand periods, they contribute to grid stability and help meet electricity needs. 

In summary, battery storage is crucial to the overall energy infrastructure during a solar eclipse. It helps bridge the gap between fluctuating solar power production and consistent electricity demand, ensuring a reliable and uninterrupted power supply for consumers.

Australian Government Policies for Rooftop Solar Installation

Australian government policies regarding rooftop solar panel installation are in place.  

Here are some general aspects of Australian government policies related to rooftop solar:

1. Solar Rebates and Incentives:

The Australian government and some state and territory governments have offered various rebates and incentives to encourage the installation of rooftop solar panels.  

These incentives may include Small-scale Technology Certificates (STCs) or Solar Credits, which can significantly reduce the upfront cost of installing solar systems.

2. Feed-in Tariffs (FiTs):

Many states and territories in Australia offer feed-in tariffs, compensating homeowners for excess electricity generated by their solar panels and fed back into the grid. The rates and structures of these tariffs can vary by region. 

3. Renewable Energy Targets:

Australia has set a renewable energy target to increase the share of renewable energy in its overall energy mix. These targets may influence policies that support the installation of rooftop solar panels. 

4. Solar Homes Programs:

Some states have introduced Solar Homes programs, offering additional incentives and support for households to install solar panels. These programs may include grants, low-interest loans, or additional rebates. 

5. Regulations and Standards:

There are regulations and standards to ensure the safety and quality of rooftop solar installations. Installations typically need to comply with standards set by the Clean Energy Council, and installers may need to be accredited by the relevant authorities. 

6. Solar and Battery Storage:

Some government policies may extend to support the integration of solar panels with energy storage systems, such as home battery storage. This is seen as a way to enhance the reliability and stability of the power grid. 

The Clean Energy Council and the Australian government’s official websites have the most up-to-date and accurate information on rooftop solar policies.  

Additionally, specific guidelines can vary by state and territory, so it’s important to consider regional regulations and incentives. Read about this on our detailed blog, the best solar rebate and incentive guide for Australia

What’s The Optimal Temperature Of Solar Panels In Australia?

Whats The Optimal Temperature Of Solar Panels In Australia

As we’re well aware, Australian summers can become quite intense. At times, heat can leave you with barely enough energy to make a quick trip to the pool and back.  

Solar panels perform optimally under specific temperature conditions like the human body. When solar panels become excessively hot, the risk of overheating starts.  

In such instances, the efficiency of solar panels significantly declines, impacting their ability to capture energy from the sun. But what’s the optimal temperature of solar panels in Australia? 

Let’s delve into the ideal weather conditions for solar panels without delay. It will show how temperature affects solar panels and the advantages of harnessing the optimal temperature for these energy systems.

Best Temperature for Solar Panels in Australia

Okay, let’s talk about the best temperature for solar panels in simple words. Most solar panels have a number called a coefficient, which is usually between -0.20 and -0.50 per cent for each degree Celsius.  

The closer this number is to zero, the less the solar panel is impacted by getting hotter. 

Imagine this number is -0.50 per cent. It means that the solar panel’s efficiency decreases by 0.50 per cent for every degree above the best temperature for solar panels, which is 25 degrees Celsius (77 Fahrenheit). 

For instance, if it’s now 32 degrees Celsius, that’s 7 degrees more than the best temperature of 25 degrees Celsius. To figure out how much less power your solar panel will make, you multiply the temperature difference by the temperature coefficient: 

7 x -0.50 = -3.5. 

So, when your solar panel’s temperature is 32 degrees Celsius, its power decreases by 3.5 per cent.

How Hot Do Solar Panels Get in Australia

solar energy

You might have wondered, “Do solar panels get hot?” The answer is yes. They can get hot depending on the type, maintenance, and making.  

When solar panels overheat, they don’t work as well. Even though many solar panels can handle harsh weather, the ideal temperature for them can vary based on where you are, the material of your roof, how much sunlight they get, and more.  

So, it’s tricky to say exactly how hot they can get. Also, black solar panels, while they look nice, can absorb a lot of heat, making them not the best choice in hot weather.  

Solar panels, made with dark silicon cells and metal, are good at conducting heat, but this can affect how well they work in warmer places, even if manufacturers try to prevent overheating. 

In Australia, solar panels can reach high temperatures during the summer months, often exceeding 65 degrees Celsius (149 degrees Fahrenheit) on scorching days.  

The intense sunlight and ambient heat contribute to the elevated temperatures of solar panels. These high temperatures can impact the efficiency of solar panels, as their performance tends to decrease with rising temperatures.  

It’s essential to consider strategies such as proper ventilation, tilt, and installation techniques to mitigate overheating and optimise the overall effectiveness of solar energy systems in the Australian climate.

How Does Temperature Impact Solar Panel Efficiency?

The sun has the potential to generate an enormous amount of power, far exceeding what is needed to meet the global electricity demand. Solar panel systems, using photovoltaic (PV) technology, convert sunlight into usable electricity, offering an abundant renewable energy source.  

While many might assume that stronger sunlight produces more electricity from solar panels, the reality is different. Excessive heat can lead to declining performance and energy output from solar panels.  

As the temperature of a solar panel rises, its energy output decreases, negatively affecting overall power generation. It happens because solar panels rely on photons to excite electrons in the semiconductor.  

If a solar panel is already warm, most electrons in the semiconductor are already excited, causing a drop in the overall voltage the panel can generate.  

Additionally, the silicon commonly used in solar panels accelerates heat build-up on hot days, compounding the issue. The solar panel’s temperature coefficient provides a helpful measure to quantify the performance loss due to heat.

Optimising Solar Panel Temperature/Understanding the Temperature Coefficient

solar panels

The temperature coefficient indicates how much your solar panel’s performance decreases for each degree Celsius above the optimal temperature.  

The optimal temperature for solar panels is 25 degrees Celsius, and any above temperature impacts their performance negatively. 

All solar panels in Australia undergo testing at 25 degrees Celsius, but the temperature impact can vary among manufacturers.  

Therefore, each manufacturer must provide the temperature coefficient specific to their solar panel.  

Some manufacturers intentionally design their panels to perform better in Australian conditions, operating efficiently at higher temperatures with a lower overall temperature coefficient.

How to Keep Solar Panels Cool in the Heat

Now that you know the best temperature for solar panels is 25 degrees Celsius, what can you do to prevent them from getting too hot? 

Luckily, most certified solar panel installers take steps to help solar systems cool naturally. They use tricks to enhance the abilities of solar panels in harsh conditions.  

One common trick is leaving about six inches of space between the rooftop and the solar panels. It allows air to circulate and cool down the panels.  

However, be careful about the surroundings—consider the shape and size of your building and how much shade and wind it gets.  

Leaving a big gap might expose your panels to damage during strong winds or from tree debris. Another option is using a ventilation fan for airflow without the risk of damage. 

As mentioned earlier, light-coloured roofing or solar panels can be a good choice in warmer conditions because they reflect more sunlight. Some solar panels now have water cooling systems, but these are more common in big solar power farms than for individual use.  

These systems have pipes along the panel’s top that spray water on the glass surface. There’s also ongoing research to make solar panels able to pull water from the air to cool down, similar to how humans sweat.

Solar Panel Efficiency in Colder Condition

People often think that solar power only works well in colder countries. However, solar panels can work great if sunlight and cold temperatures don’t harm their overall performance.  

The key is to have certain conditions in place for the best results. What’s most harmful to solar panels is shade, as it blocks them from absorbing sunlight.  

Even on a day with perfect conditions for maximum output, shade can cancel out all the solar performance. When installing solar panels, it’s crucial to ensure shade won’t cover the panels’ surface to get the best solar output.

Most efficient Solar Panels of Australia in this Temperature

Are Solar Batteries Worth It In 2024?

Are Solar Batteries Worth It In 2024

Back in 2010, Australia saw a surge in solar battery installations all around the country. Since then, about 3 million homes have enjoyed the perks of rooftop solar, including lower electricity bills than those with just a grid connection.   

To paint a clearer picture, it is estimated that in NSW, per kilowatt of energy generated by solar panels saves you about $400 annually. You have a standard 6.6kW solar system on your rooftop, and your savings for the said year will be about $2640, which is $660 in a quarter!    

There is a way in which you could get even more out of your solar panel system; what might that be? Adding a solar battery system is the answer.  

However, batteries for solar systems are by no means a small investment, so the question remains: are solar batteries worth it in 2024 as a homeowner? We will find out soon enough. But first, let’s get to know some basics about solar batteries. 

Types of Solar Batteries

Solar batteries, also called solar energy storage systems, play a crucial role in solar power setups by storing surplus energy generated during sunny periods for later use, such as during nights or overcast days.  

These batteries come in various types, each with distinct characteristics and advantages.  

Lead-acid batteries, including Flooded Lead-Acid (FLA) and Valve-Regulated Lead-Acid (VRLA) options, offer durability and cost-effectiveness, with VRLA batteries like Absorbent Glass Mat (AGM) and Gel batteries being maintenance-free.  

Lithium-ion batteries, such as Lithium Iron Phosphate (LiFePO4), Lithium Nickel Cobalt Manganese Oxide (NMC), and Lithium Nickel Cobalt Aluminium Oxide (NCA), provide high energy density, extended lifespan, and enhanced safety.  

Flow Batteries, represented by Vanadium Flow Batteries, offer a liquid electrolyte and are known for their extended cycle life and scalable capacity.  

Saltwater Batteries, specifically Sodium-Ion Batteries, are environmentally friendly and potentially cost-effective. Nickel-iron or Edison batteries are durable but have lower energy density. Hybrid Batteries combine different technologies for optimised performance.  

Choosing the correct solar battery involves cost, space, maintenance, and intended application, while ongoing advancements in battery technology may introduce newer options. 

Reasons Why You Should Get Solar Batteries

Solar battery prices are not low, but the payback period goes down with the price hike of energy in Australia every day, and due to the current economic environment, I can only see energy prices rise.  

According to the Australian Energy Market Operator (AEMO), the wholesale cost of power in the National Electricity Market (NEM) jumped by 141 per cent in the first three months of 2022 compared to the same quarter last year.  

That said, storing the surplus of energy generated by your solar panels sounds like a sound investment, doesn’t it?   

Here are some more reasons-    

End of Net Metering in Australia

Net metering is a system that allows you to send the excess power generated by your solar panels to the grid and get a portion of the exact amount back on demand.  

People were utilising the grid practically as a storage facility when the net metering system was still in place, but that luxury is no longer available.  

Net metering was available until April 2020 in the Northern Territory; however, the benefit is no longer at one’s disposal for solar systems constructed after that date.  

Essentially, with the end of net metering, you no longer have the freedom to get a one-to-one net metering service (a kW received per kW given).   

That doesn’t mean you don’t have other means to store the energy in the grid; you do; however, that is not as beneficial as net metering and not certainly as profitable as having your solar battery.   

Solar panels can generate a different amount of energy all day, as the sun doesn’t shine as bright from sunrise to sunset.  

The maximum amount of electricity generated by the solar panels is between 12 and 3 pm. An average Australian household only consumes a little electricity during that time since they are the majority at work.    

Studies have shown that, with the surge of electric prices off the grid, it needs to make more financial sense to store the excess energy in the grid; instead, having your solar battery and using it on demand will be much more profitable in 2023.   

Electricity Prices are Higher at Night

As a storage unit does require significant investment, you decided to export the surplus of electricity to the grid.  

But, keeping in mind that an average household requires more energy at night than in the day, you will be paying more to buy back that amount of electricity you exported at night.   

So, it’s evident that storing the surplus in a solar battery makes more sense than repurchasing it at a higher electricity cost. 

Grid Outages

There are occasions in which people suffer from grid outages. It can be during a scheduled check-up of the grid, a devastating storm, or just about any other reason. It’s more common than you would think. In those cases, a solar battery can be your resolve.   

We are positive you would prefer to avoid coming home to a fridge full of rotten food. To have an uninterrupted supply of energy that you have all the control over, having a battery storage unit makes perfect sense.   

Yes, of course, you could opt for a backup generator, but they are noisy, and it defeats the purpose of having installed solar on your rooftop in the first place. It runs on diesel, a non-renewable energy source contributing to carbon emissions.    

Are Solar Batteries Worth It?

It makes sense for a large energy user to opt for solar batteries. They are worth the price, and here is why-   

Solar battery cost is significantly coming down as we speak. For instance, back in 2020, a 6kw solar battery cost about $10,000, which now is about $7,700  

It is the only way to go for those who live off the grid   

Without the benefit of Fit, having one’s storage system saves on power bills even more   

Complete control over your energy consumption   

Power backup for days in the event of a power outage, and with the addition of solar panels, you can forget the grid.     

Solar and Battery Package Price in Australia: How Much Do Solar Batteries Cost?

It’s tough to figure out the actual price of solar batteries because it depends on many variables. For example, it will depend on your power needs, whether you have any power-hungry appliances, household size, geographic location, etc.  

Depending on these variables, you can determine how much of a storage unit you require. Thus, That’s how the cost of solar batteries is estimated.   

But to give you a rough idea, the price of a kWh of residential solar battery storage can hover over the $1000 mark.  

These include the cost of installation and GST. Remember that the battery brand and all the other factors mentioned matter in the end, and prices vary depending on those factors. 

10kw Solar Battery Price

As of October 2023 in Sydney, NSW, the current cost of a 10kW solar battery paired with a 6.6kW solar panel system is $12,888. This price includes two 5.1 kWh modules integrated with a 6.6 kW solar system. The potential payback time for this system can be less than 4 years.  

The Tesla Powerwall, which has a storage capacity of 13.5 kWh, costs approximately $1,150 per kilowatt-hour.  

When considering the broader market, solar batteries without the solar component typically fall from $900 to $1,200 per kilowatt-hour. The specific pricing varies based on the brand and model. 

6kw Solar Battery Cost

The solar battery storage cost is how much you pay for each unit of electricity it can store, and it’s usually measured in dollars per kilowatt hour ($/kWh).  

Typically, these batteries cost between $900 and $2,000 per kilowatt-hour. If you want a solar setup with a 10.2-kilowatt-hour battery and a 6.64-kilowatt solar system, it might cost you around $12,888. 

If you just want the battery alone, without the solar system, a solar battery alone can cost $990 per kilowatt-hour. It includes a particular device called a hybrid inverter that connects the battery to the solar system. 

For a specific type of battery called the Tesla Powerwall, which has a 13.5 kilowatt-hour capacity and comes with its inverter, the price is $1200 per kilowatt-hour. 

Another type of battery, the Sungrow 9.6 kilowatt-hour solar battery, is priced at $1227 per kilowatt-hour. This cost includes a 5-kilowatt hybrid inverter. 

If you’re looking at a solar panel system with a 6-kilowatt capacity, and it includes a battery with a capacity of 16.6 kilowatt-hours, the total cost for installing this combined system can range from about $19,935 to an average of $25,235.  

The exact price depends on the type and quality of your chosen system. For more details, check out how much a 6kW solar battery costs in Australia. 

Solar battery ROI

The return on investment (ROI) for solar batteries in Australia is influenced by various factors, such as the system’s initial cost, local electricity rates, solar generation capacity, and available government incentives or rebates.  

Key considerations include the upfront expenses encompassing the battery, inverters, installation, and related components.  

The cost of grid electricity in your area is pivotal, with higher rates potentially leading to faster returns, as stored solar energy use during peak periods saves on electricity bills.  

Solar panel efficiency, battery performance, and lifespan also impact long-term returns. Government incentives, rebates, and electricity consumption patterns, especially during high-demand periods, contribute to overall ROI.  

Monitoring technological advancements is crucial for assessing the economic viability of solar battery systems over time.  

Seeking professional analysis and staying informed about industry trends and policy changes are advisable for making well-informed investment decisions in Australia.  

How To Choose Solar Batteries?

solar storage

To choose solar batteries in Australia, consider your energy needs, capacity and performance, compatibility with your solar system, warranty, and cost. Assess the battery’s kilowatt-hours (kWh) storage capacity to match your daily usage.  

Look for reliable brands and models with proven performance and longer lifespans. Ensure compatibility with your existing solar system, and check for government incentives or rebates. Compare the cost per kilowatt-hour and warranty terms.  

Consider factors like installation requirements and whether the battery supports backup power. Seek professional advice to tailor your choice to specific needs and conditions.  

State Rebates for Solar Batteries

State rebates for solar batteries vary across Australia. States like South Australia, Victoria, and Queensland offer specific incentives and rebates for solar batteries.  

However, rebate programs and amounts can change, so it’s crucial to check the latest information from your state government or relevant authorities for the most up-to-date details on solar battery rebates.  

Solar Battery FAQs

What Size Solar Battery Do I Need to Power a House?

The size of the solar battery needed to power a house in Australia depends on various factors, including your energy consumption, the size of your solar panel system, and your specific energy needs.  

On average, a medium-sized household might require a solar battery with a capacity ranging from 5 kWh to 20 kWh.

Solar Energy Rebates That are Affecting Homeowners and Renters

Solar and Battery Rebate in Australia

Solar energy incentives: Several states have implemented measures impacting homeowners and renters to promote the adoption of clean energy.  

Recognising the significance of transitioning to sustainable energy sources, the governments of New South Wales (NSW), the Australian Capital Territory (ACT), and Western Australia (WA) have introduced various changes to solar rebates, incentives, and subsidies. 

In NSW, the Solar for Low-Income Households Program seeks to enhance accessibility to solar energy for low-income households, thereby reducing power bills and promoting sustainable energy use in economically disadvantaged communities. 

Effective July 1, 2023, the ACT Sustainable Household Scheme has introduced new eligibility criteria. Stand-alone homes (non-unit titled properties) with an unimproved value (UV) of $750,000 or less in 2022 are eligible for all scheme products except solar.  

To qualify for solar under the scheme, the property’s UV 2022 must be $450,000 or less. Meanwhile, unit-titled properties are eligible for all program products if their unimproved value is $300,000 or less in 2022. 

For Western Australian solar households in Perth and the southwest, Synergy is the power provider, offering a solar feed-in tariff (FiT) under the Distributed Energy Buyback Scheme (DEBS).  

As of July 1, 2023, DEBS rates for Synergy customers include peak rates of 10 cents per kilowatt-hour (kWh) for electricity exported between 3 pm and 9 pm and off-peak rates of 2.25 cents per kWh for electricity exported between 9 pm and 3 pm. 

Comparatively, in the 2021-2022 period, peak rates were set at 10 cents per kWh for electricity exported between 3 pm and 9 pm, while off-peak rates were 2.5 cents per kWh for electricity exported between 9 pm and 3 pm. 

Increase in the Minimum Wage

Commencing on July 1, 2023, the minimum wage in Australia is set to experience an elevation, impacting numerous workers across diverse industries.  

The Fair Work Commission determined the minimum wage rates. They declared a 2.5% raise, equivalent to $20.33 per week or approximately $1,057.80 annually for full-time employees. 

This escalation is intended to tackle wage stagnation concerns and support workers in maintaining a reasonable standard of living.  

It is essential to recognise that the extent of the minimum wage increase may vary based on different awards and employment sectors.  

Hence, referring to the Fair Work Commission website or seeking professional guidance for precise details is advisable.  

Government Incentive for Renewable Energy at the Federal Level

The Small-scale Renewable Energy Scheme (SRES) introduced by the federal government is a financial encouragement. They are set up to adopt small-scale renewable energy systems, like solar panel systems, small-scale wind systems, small-scale hydro systems, solar water heaters, and air source heat pumps.  

This initiative benefits Australia’s individuals and small businesses by generating Small-scale Technology Certificates (STCs).  

Established in 2011 to contribute to Australia’s Renewable Energy Target, the scheme has played a pivotal role in promoting the use of renewable energy. 

The success of Small-Scale Technology Certificates (STCs) in boosting the demand for solar installations among households and small businesses is noteworthy.  

Accessible to all Australians, STCs present a valuable incentive. They are applicable for solar panel installations up to 100 kW. 

Each STC holds a monetary value that can be credited to the installer or traded on the open market for a point-of-sale solar rebate. The maximum number of certificates per solar system is determined by the system’s location, installation date, and electricity consumption measured in megawatt hours (MWh).  

This includes electricity generated by a small-scale solar panel, wind, or hydro system over one or five years or a maximum deeming period and electricity displaced by a solar water heater or heat pump over a maximum deeming period. 

The Renewable Energy Target speeds up the creation of tradable STCs, providing a financial incentive for increased electricity production from renewable sources.  

These certificates are issued and distributed through the REC Registry, an online trading platform managed by the Clean Energy Regulator. 

STCs are calculated within the Small-scale Renewable Energy Scheme based on the solar system’s location, installation date, and the duration over which they are generated.  

The scheme is gradually being phased out, with the value of STCs decreasing annually on the 1st of January until 2030, when the scheme is set to conclude on December 31. 

For further details on calculating STCs and solar credits, visit our page.  

Governments at the state level

The picture is highly variable at the state level. There are numerous state government solar home rebates and incentives available to residents of Victoria, New South Wales, South Australia, the Northern Territory, Western Australia, or the ACT. If you live in Queensland or Tasmania, there currently need to be state government incentives for home solar batteries.  

Feed-in Tariff (FiT) for electricity retailers

Households in all Australian states are reimbursed by their electricity retailer for any excess solar power generated by their system and exported to the grid. A feed-in tariff is the amount shown as a credit on your electricity bill. The value of the feed-in tariff varies by state and by electricity retailer.  

Rebates, Incentives, and Programs for Energy Efficiency Products

The Victorian Energy Upgrades (VEU) initiative stands as a government-driven energy efficiency program designed to assist households and businesses in Victoria in saving money on their energy expenses and reducing greenhouse gas emissions.

Is Your Roof Compatible For Solar Panel Installation?

Is Your Roof Compatible For Solar Panel Installation

Most new houses in Australia have concrete tiles or metal sheeting for their roofs, ideal for solar installations. However, many average Australian households have different materials. 

Even some new homes are choosing these alternative materials. And today, we will try to answer a necessary question about solar panel systems.  

So, is your roof compatible for solar panel installation? And whether these different roofing materials are compatible with solar energy systems. 

Many roofs in Australia can have solar panels. Roof strength, shading, roof surface, direction, and slope can affect how well the solar panels work.  

If a roof is strong enough for someone to walk on, it’s probably strong enough for solar panels. And roofs facing east or west make more electricity. 

The angle of the roof should match where you live for the best electricity all year. Flat roofs are suitable. But you must be careful when installing solar panels to avoid shadows from other rows. 

Generally, most Australian roofs should work well with solar panels and benefit homes or businesses.  

Ideal Roofing Materials for Solar Installation

Choosing the best roof material is essential when installing solar panels.  

Solar companies think about how easy it is to install, and they also care about the safety of your home and the installer. Hence, look at the best materials compatible with your solar roof.  

Asphalt Shingles

These are becoming more popular in Australia because they are affordable and flexible. Fibreglass shingles, which are resistant to fire, are a good choice for Aussies.  

Although asphalt shingles are cheaper than concrete tiles, they only last for a while because they deteriorate quickly. They are great for installing solar panels because they easily put railings and racks on.  

If some shingles are damaged, they can be replaced easily. Since they are lightweight, adding solar panels usually doesn’t require changing the roof’s structure. 

Metal Sheeting

Metal roofs are standard in Australia. They are made from materials like steel, tin, or aluminium. These are excellent for Aussie homes for their rust prevention, lightweight, fire resistance, and durability.  

Metal roofs also spread heat well with solar panels. They act as an insulator in summer, lowering the house’s temperature. 

Concrete Tiles

Concrete tiles are famous for Australian homes because they are affordable, durable, and insulated.  

However, they add a significant weight to a house. It adds about 12 tonnes for an average-sized roof.  

In comparison, metal roofs add approximately 1 tonne. This means a concrete tile roof may need extra support if you want to add solar panels.  

Spare tiles should be available during installation, as installers may break some while walking on the roof.  

Roofing Materials That May Cause Issues

solar panel installation
Setting up solar panels on roofs is generally trouble-free. However, it becomes challenging when certain roofing materials create issues. That’s why some installers suggest avoiding them.   

Clay Tiles

Terracotta and other clay tiles are visually appealing but create challenges during installation. Unlike concrete tiles, clay tiles can break and have a lower load-bearing capacity.  

Walking on the roof is likely to cause tile breakage. So, having plenty of spare tiles for the installer is essential. 

Additionally, removing the tiles may compromise the roof’s water seal. Some installers choose to replace the tiles beneath the solar panels with more resilient composition tiles or use special solar panel mounting tiles.  

Regardless, it will indeed become more expensive for a solar roof.  

Slate Tiles

Slate roofs can be tricky for solar installation because of their fragile slate. Walking on the tiles will likely result in breakage.  

Slate is the heaviest roofing material, requiring a structural assessment before adding solar panels.  

Asbestos Roofs

Homes with asbestos roofs cannot have solar installations, as the Clean Energy Council prohibits.  

The carcinogenic properties of asbestos pose a significant safety hazard for installers, along with its low load-bearing capacity.  

If your roof is made of asbestos sheeting, it is strongly recommended to replace it for safety reasons. 

Are Solar Tiles a Good Option?

You can change your roof or part of it into solar tiles. Solar tiles are like regular roofing tiles but also work as solar panels.  

GoodWe have a new type called BIPV solar tiles that look good and work well. They are a great alternative to both regular roofing materials and solar panels. 

Tesla also has a solar roof that can replace your whole roof and looks like a normal one. It’s even three times stronger than concrete tiles.

Roof Compatibility With Solar Energy

Not all roofs are the same. Older houses might need extra work or a complete replacement before adding solar.  

Solar panels add about 350 kg of weight to your roof. Even though it spreads over a big area, your roof’s strength is still necessary. Solar installation often requires the panels to be attached to the joints in your roof.  

If the joints are bad or the roofing materials are falling apart, you might have to fix those issues before adding solar. 

Getting solar is more than just a significant investment for your home. It also adds value to your house.  

On average, solar can increase your home’s value by $29,000. With the money you save from using solar, upgrading your roof is a good idea.   

How is Your Roof Suitable For Solar Panels?

If your Australian roof is sturdy enough to handle someone walking on it, it’s likely strong enough for solar panels.  

The effectiveness of solar panels depends on factors like roof strength, shade, angle, direction, and slope.  

Shaded roofs make solar panels produce less electricity, but roofs facing east or west generate more solar energy.  

Your roof’s angle should match where you live for the best electricity all year. If your roof is flat, it’s easy to work on.  

But you should be careful during installation to prevent shades. It can make the panels work less. Most roofs should work well with solar panels and benefit your home or business.  

What are the Best Roof Conditions for Solar Installation?

In Australia, most roofs can handle solar panels, bringing benefits to homes or businesses, although the results may vary.  

The strength of your roof is crucial, and if it can support a person, it can likely hold solar panels.  

Standard-pitched or skillion-style roofs with wooden trusses or rafters are suitable for solar panel systems.  

Less shade on your roof throughout the year is ideal for the best solar production.  

If your roof has heavy shading, getting a good result may be challenging, but installers can use tools like microinverters and optimisers to minimise power loss.  

Roof surface matters too; while concrete tiles are easy to work with, terracotta and slate require extra care during installation.  

Roof orientation affects power production, with northern-facing roofs being optimal, but easterly or westerly roofs can also be beneficial based on the time of day.  

The roof slope influences performance, with the ideal angle matching the home’s latitude, but variations have a minimal impact on electricity generation.  

Understanding these factors helps determine if your roof is suitable for solar and can maximise its benefits.  

Space Requirements for Your Solar Roof

solar roof

You might also wonder if your roof has enough space for solar. A standard 6.6kW solar panel system with 24 panels requires about 45 square meters of roof space. 

But don’t worry if space is a concern. New technologies focus on high-wattage panels, requiring fewer panels for more power.  

While a north-facing roof is typically best for solar, the northeast and northwest are also good. Installing panels on two sides of the roof is recommended to get the most energy throughout the day. 

Contact Solar Emporium for the best solar solutions, and check out our solar packages.   

Solar Roof Compatibility FAQs

Installing solar panels on your roof allows you to collect energy safely and efficiently. Some rooftops are too small, have the wrong direction, are overly shaded, or too steep. Here are some questions to determine if your roof suits a solar installation.  

What Exactly are Rooftop Solar Panel Systems?

Roof-mounted solar panel systems are typically available in flexible and rigid configurations. Bolts, brackets, and mounting hardware secure both to the roof of your RV or van.  

The most durable option is rigid panels. Flexible panels have a low-profile appearance, are lightweight, and are easy to handle. 

When Should I Change My Roof?

Before adding solar, checking if your roof is in good shape and not too old is essential. If your roof is close to the end of its life, replacing it before installing solar is wise.  

Solar panels usually last 30 to 35 years, so if your roof is about five to 10 years away from needing replacement, it’s a good idea to have a professional assess its condition. 

Replacing the roof before installing solar ensures you won’t have to remove everything a few years into your solar setup.  

What's the Lifespan of My Roof?

Different roofs have varying lifespans. As a general guide, clay tile, slate, and copper roofs can last up to 50 years, wood shake roofs have a lifespan of about 30 years, and cement shingles last around 20 years.  

Will Solar Panels Harm My Roof?

Properly mounted solar panels won’t damage your roof. The key is to use the proper mounting hardware for a safe and secure attachment to your rooftop. 

If done correctly, solar panel installation should be suitable for your roof. Technology has improved, making mounting solar panels easier, and in some cases, solar panels can even protect your roof instead of causing damage. 

Is Shading Bad for Solar Panels?

Solar panels can still work in the shade, but their capacity is reduced. A general rule is that panels in the shade produce about half as much energy as those in direct sunlight.  

Trees to the north of your home pose the least shading obstruction. Trees on the north side can block the midday sun, crucial for solar power production.  

Your roof’s features, like dormers and chimneys, can create shading challenges. While shade decreases efficiency, it doesn’t mean solar is impossible.

Which Way Should My Solar Panels Face?

In the Southern Hemisphere, solar panels work best on a north-facing roof. West-facing panels produce less energy in the morning but more in the afternoon, while east-facing panels do the opposite.  

Panels facing south receive almost no direct sunlight. Panels should face true north for optimal efficiency, which may differ from magnetic north. If you can’t face them north, northeast and northwest-facing panels will also work, albeit with lower efficiency. 

Do I have Enough Space on My Roof?

Ensure your roof has enough space for solar panels. An ideal roof for solar is large, rectangular, and free of obstacles like chimneys. Use a solar calculator to determine how many panels you need to meet your energy needs.

Tips To Prevent Rooftop Solar Fires In Australia

Tips To Prevent Rooftop Solar Fires In Australia

Solar panels installed on rooftops have become widely embraced for their eco-friendly and sustainable energy contribution. They come with various advantages, such as cost savings on electricity and a diminished environmental impact. 

Nevertheless, there has been a growing worry surrounding the safety of rooftop solar setups, with reports suggesting an increase in solar-related fires.  

Therefore, today, we will investigate tips to prevent rooftop solar fires in Australia. We will soon find out whether rooftop solar fires are on the rise and try to offer practical guidance for homeowners safeguarding their solar installations. 

Are Solar Fires Increasing in Australian Rooftops?

Some concerns were raised regarding solar fires recently. A few cases were filed in Victoria, New South Wales and Northern Territory. It’s vital to address these situations carefully. Solar panels aren’t dangerous in general. 

However, they require proper installation, maintenance, and regular inspection to minimise associated risks like any electrical system. 

In Victoria, approximately 3,000 house fires take place annually, as reported by the Country Fire Authority.  

There are a significant number of solar-powered households in Victoria. These stand at around 510,000 by the end of 2022. The percentage of these households experiencing a fire is approximately 0.01%. 

Only four DC isolator fires were documented. But this year’s total marks a significant increase. Specifically, the DC isolator component of solar panel systems has been responsible for fires at 11 different properties in the Northern Territory this year. 

These increased incidents have prompted NT Work Safe to issue a safety alert. They also released 22 infringement notices for solar panel installations between January and August.

Are Only DC Isolators Responsible for Rooftop Fires?

The primary factor behind rooftop solar fires is faulty electrical units. It includes DC isolators, inverters, and wiring.  

DC isolators disconnect solar panels from the other electrical system for maintenance or safety purposes. Inverters are essential for transforming DC electricity into AC electricity from solar panels for your home. 

Storms or severe weather can damage solar panels, rendering them a potential fire hazard. Also, when a solar panel system is not installed correctly, it increases the fire risk. Solar panel systems also require regular maintenance to function safely.  

Therefore, we can see that DC isolators are not the only fire hazard components. Let’s go through them in detail. 

Causes of Rooftop Solar Fires

Water Infiltration in DC Isolators

DC isolators, especially those on rooftops, are a well-documented source of fires within PV systems.  

Traditionally, rooftop isolators were authorised in Australia to assist in the disconnection of the system at the solar panel array. It meant they had to be located on the roof. 

However, these rooftop isolators are more vulnerable to damage due to their exposure to the elements.  

Additionally, their less ideal-placement can result in issues going unnoticed until it’s too late. While recent changes permit alternatives to rooftop isolators, millions have already been installed. 

Proper installation methods to maintain the isolator enclosures’ improved protection allow water to stay intact inside the section.  

This can lead to the erosion of terminals. In heavily overflown isolators, it can also damage internal components.  

When the isolator provides electricity in these conditions, it increases the chance of leading to fires. 

Several common entry points for water in DC isolators include: 

Open Connections: Failure to properly seal units allows water to enter the connection point slowly. All entries, including caps for unused entries, should be securely closed. 

Uncovered Screws: When screws are not sealed properly, water can seep in gradually from the opposite side of the screw. 

Incorrect Cable Glands: Multi-hole cable glands can result in fire hazards. Unused holes in the glands should be properly plugged. 

Improper Enclosure Penetrations: Drilling holes without properly sealing them can allow water to infiltrate. Infiltrations on any surface carry a higher risk of water dripping onto components. 

Over-tightened Screws: It leads to cracked openings or loose screws, causing ineffective seals.  Both scenarios occur when the manufacturer’s settings are not followed, enabling water infiltration. 

Cable Termination

Ensuring that components and other connections are correctly tightened is essential for the smooth flow of electrical current.  

When prescribed torque settings are disregarded or when connections are left loose, it can lead to the formation of hot joints. The heat generated can melt the plastic surrounding the cables, setting the stage for a fire. 

Additionally, paying attention to the length and positioning of cables within the enclosure is crucial to prevent any damage to the wires.  

Each plug and socket constitutes a connection, and loose or mixing connectors from different brands and models can also result in a hot joint on the rooftop. 

Module Damage

While solar modules are designed to withstand various environmental conditions, damage to the module can induce hidden internal cracks.  

Microcracks, which may not be visible, can develop within the module’s cells. It could lead to hotspots. These hotspots, in turn, have the potential to ignite fires. 

Cracks and micro-cracks in the cells can arise from various sources, including: 

  • Impact damage  
  • Installation of earthing lugs against the module’s back sheet, causing abrasion. 
  • Damage is caused by individuals walking on the modules or during improper transportation. 

An alternate way for damage is to separate the module’s back sheet. It results in water penetration into the solar panel and a short circuit of the module’s current to the earth.  

While this typically doesn’t lead to fires, it decreases system efficiency and creates potential hazards on the roof.

How to Prevent Rooftop Solar Fires?

For safer solar panel installation and maintenance, consider the following: 

Choose Certified Manufacturers and Installers: With the growing solar industry, ensure your installers are certified by the North American Board of Certified Energy Practitioners (NABCEP) to reduce fire risk. 

Adhere to the National Electric Code (NEC): Ensure your installers follow NEC guidelines for safe electrical design and installation. 

Opt for Non-Plastic Materials: Avoid panels with plastic frames and back sheets, as these can fuel fires. 

Assess Roof Fire Rating: Use Class A roof coverings for safer installations, as lower classes may have combustible insulation, exacerbating rooftop fires. 

Develop Emergency Plans: Plan rapid shutdown and rooftop access in collaboration with the fire department to aid firefighting efforts. 

Maintain Adequate Roof Space: Ensure panels have enough space on the roof to allow firefighters to ventilate the building and tackle fires. 

Inspect Connectors: Check connectors to prevent electrical failures and potential fires due to incompatible cables. 

Schedule Regular Maintenance: Regularly test and maintain solar panels to identify and address wear and tear issues. 

Address Weather-Related Risks: Consider protection against physical damage from weather events, such as hail, wind storms, wildfires, or earthquakes, depending on your location. 

Despite potential risks, adopting renewable solar power offers business opportunities, but it’s crucial to understand and address associated risks and challenges.
