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.

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.

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.   

This program extends rebates or discounts on various energy-saving products and services, encompassing:

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.

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.

Differences Between Solar Batteries And Solar Inverters

Differences Between Solar Batteries And Solar Inverters

Two essential components of a solar panel system are solar batteries and solar inverters. The world is increasingly turning towards renewable energy sources. Therefore, understanding the differences between these two elements is essential.  

There are different roles for solar batteries and solar inverters. There are also significant differences between solar batteries and solar inverters. Today, we will explore their functionalities, significance, and how they contribute to the efficiency of solar panel systems.  

What is a Solar Battery?

A solar battery is an additional component integrated into your solar energy setup. It is designed to store extra electricity produced by your solar panels.  

Its purpose is to store this excess energy for later use. Solar Batteries mainly store energy when your solar panels are not actively generating electricity. Night, cloudy days, or power outages are the simple examples.  

A solar battery helps you utilise more of the solar energy you generate. Without a solar storage system, any extra electricity generated by your solar panels gets directed to the grid.  

It gets distributed to others instead of maximising the use of the electricity your panels initially produce.  

What is a Solar Inverter?

A solar inverter is also a crucial component in a solar energy system. Its primary function is to transform direct current (DC) electricity into alternating current (AC) electricity from solar panels.  

How it works

In electricity, DC maintains a constant voltage in a single direction. At the same time, AC involves the flow of electricity in both directions within the circuit, as the voltage alternates between positive and negative. Inverters belong to the category of power electronics, a class of devices responsible for controlling the flow of electrical power. 

Essentially, an inverter converts from DC to AC by rapidly waving the DC input’s direction. This process results in the transformation of a DC input into an AC output.  

Moreover, by utilising filters and additional electronic mechanisms, the inverter can generate a clean, recurring sine wave that varies in voltage. This sine wave represents the pattern of voltage over time.  

And it is essential for the grid’s use without causing harm to electrical equipment. Electrical devices are designed to function within specific frequencies and voltages.  

The sine wave pattern produced by the inverter ensures compatibility with these requirements, safeguarding the grid and connected equipment. 

Differences Between Solar Battery and Solar Inverter

Both types function as energy storage units. The primary contrast is in their charging methods and connection sources. 

Solar batteries differ from inverters and undergo multiple recharging cycles directly linked to solar panels to receive and store power.  

Their lifespan typically ranges between 5 and 15 years. It depends upon maintenance.  

In essence, solar batteries are tailored for multiple recharges and directly acquire power from linked solar panels.  

In contrast, inverters rely on chemical reactions within the unit for their power source.  

Primary Differences Between Solar Battery and Inverter

solar inverter
  • A solar storage system primarily stores power, whereas the inverter converts AC power into DC. 
  • During a power outage, a solar battery promptly shifts from the primary power source to back up battery power, while the inverter may have an unavoidable delay. 
  • A solar battery system offers standby electrical power while the inverter supplies electronic backup power. 
  • Battery system variations include off-line, online, and line interruption types, while inverters come in standby and grid-connected styles. 
  • The solar battery system connects directly to home appliances, whereas the inverter connects to the storage battery and then to the home appliance circuit. 
  • Solar batteries tend to be more expensive than inverters. 
  • Battery storage and inverter vary in providing backup power.  
  • Solar storage systems usually do not have minimal voltage change. Inverters may have voltage variations. 

Solar Battery vs Normal Battery

A solar battery and a regular battery differ significantly.  

A regular battery is typically called a deep-cycle battery. It represents a rechargeable battery extensively used in various applications, such as backup power. 

These batteries store electricity and are rechargeable through multiple sources like generators or the grid. Typically composed of lead-acid, flooded-type, or sealed-type batteries, they cater to diverse functionalities. 

On the contrary, a solar battery is purpose-built to store surplus electricity generated by a solar energy system.  

This stored energy becomes accessible to homeowners when solar panels are inactive. Solar batteries go through numerous charge and discharge cycles.  

Primarily, they are composed of lithium-ion or flow batteries. One of the significant differences between both battery types is that one specialises in solar energy systems. 

A solar and a regular battery represent distinct choices for powering a solar energy system, with the former being purpose-built for storing excess solar-generated electricity.  

Solar Inverter vs Regular Inverter

When you’re thinking about buying an inverter for your home or business, you might wonder about the differences between a solar inverter and a regular inverter.  

But it’s more complicated to answer because many things are different. For example, how they work and the battery they use. It’s vital to understand these differences well before you decide which one to buy.  

Regular Inverter Functions

The regular inverter utilises switching mechanisms to control circuits, transforming direct current (DC) to alternating current (AC). This conversion process is a fundamental objective shared by both types of inverters. 

A typical power inverter draws DC power from batteries and transforms it into AC power utilised by various appliances.  

Typically linked to the home’s power system, the inverter and its battery are part of this setup. When grid power is available, the batteries are charged; in the absence of grid power, the inverter usually switches to battery mode, allowing the use of essential appliances. 

Solar Inverter Operations

In contrast, a solar inverter encompasses components such as solar panels, a charge controller, switching circuits, batteries, and the inverter itself.  

It includes connecting appropriately rated batteries and solar panels—the inverter’s battery charges from solar panels when sufficient sunlight is available. The solar panel within a solar inverter generates variable DC, which the inverter converts into AC. 

Using a solar inverter aids in reducing electricity bills and is a viable option for both residential and commercial spaces.

Integration Between Solar Panels, Batteries, and Inverters

solar power systems

You might be wondering about solar panels. However, many questions about the necessity of an inverter and a solar battery may arise. 

Solar panels are the fundamental part of harnessing the sun’s energy. Essentially, solar panels function by collecting sunshine and transforming it into electricity. The process is straightforward. 

To capture the sun’s energy, solar panels have a negatively charged side and a positively charged side. When sunlight hits the panel, it energises the electrons within, enabling them to move from the opposing side to the positive side. 

However, this electricity is in its “raw” form, known as DC (direct current), whereas most household appliances operate on AC (alternating current) electricity. That’s where an inverter becomes essential.

Solar Inverter Integration

Solar inverters are crucial in transforming electricity to be accessible and secure. If solar panels represent the fuel tank, then solar inverters serve as the driving force. 

While generating DC electricity is essential, its usability hinges on converting solar inverters into vital AC. This conversion is important for making electricity practical for everyday use. 

These inverters significantly impact the system’s performance. Solar inverter goes beyond mere efficiency. These devices influence the quality and safety of the generated electricity. 

Traditionally, most systems incorporate a single solar inverter linked to the solar panels. However, technological advancements have led to the emergence of micro-inverters.  

These smaller inverters attach directly to individual solar panels, enabling personal monitoring and optimisation. 

This innovation not only boosts the power output for homes but also offers a significant advantage. If one panel malfunctions, the others continue to function independently.  

Solar Battery Integration

solar battery

Solar batteries serve as repositories for the surplus energy in a solar panel system. While solar panels and inverters shape the core components of a PV system, adding a battery is still optional. 

The primary work of a residential solar system revolves around creating energy during blackouts or saving money. 

When you need a lot of energy, you might use regular power lines, which can be expensive. If you make more energy than you require, it returns to the system, and you get credits for it on your future bills. 

A solar battery is like the batteries in your gadgets or cars. It stores extra electricity made by your solar panels. This stored power helps when the weather is cloudy, so you have electricity when needed. Instead of sending extra power back to the system, the battery keeps it for you. 

You don’t have to get a solar battery, but it’s a good idea. It can cut your electricity bills by another 75%, besides what you save from making your energy. 

If you’re getting a solar system, it’s smart to include a battery from the start. This makes the whole system work better and saves you more money.

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

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.
