A 13.2 kW solar system refers to the size of the solar panels and battery storage that together can generate and store up to 13.2 kilowatts of electricity. This capacity is sufficient to power most medium to large-sized homes and commercial properties, depending on energy consumption patterns. In 2025, the national average price per watt ($/W) for residential solar panels ranges from $0.88 to $0.95 fully installed, including GST and the STC rebate. This $/W figure is the industry benchmark used in the Solar Choice Price Index, as it standardises system size differences and reflects the true cost Australians pay. Harness natural energy with solar panels and store it in your battery to power your home 24/7 on clean, renewable energy. Future-proof your home and power your energy independence with a high-quality solar battery.
While your solar panels on your roof will likely last 25 years, bear in mind that you will need to replace your battery after ten years. A homeowner that sells 50% of their solar energy back to the grid and consumes the other 50% would expect to save $1,659 annually with a 6.6kw solar system. By incorporating a battery, you can store excess solar energy for use during peak times or when the sun isn’t shining, further reducing your reliance on grid electricity and increasing commercial solar sumner your potential savings. Additionally, batteries can provide backup power during outages, allowing you to keep your lights on. Depending on the state, government rebates may be available for a 4kW solar system.
The brand and technology behind your solar battery play a significant role in its price. High-quality brands like Tesla, LG Chem, and Sonnen typically offer more reliable and longer-lasting batteries, but they also come with a higher price tag. Lithium-ion batteries are the most common choice due to their efficiency and longevity, though lead-acid batteries may offer a more affordable option for those on a budget. Arise Solar has nationwide installers and offices located in Queensland, Victoria, New South Wales, and South Australia. Let us analyse your electricity bills to find the best solar system for your household or business. Evergreen solar has been helpful from selecting affordable solar panels to installation and further.
Instead of selling power back to the grid for around 8c/kWh, you will use the power you generate and save around 30c/kWh. Because of this, the return on investment for a commercial solar system is usually even faster than a standard residential installation. The payback period for a simple commercial solar system can be less than three years. Like most of North and Far North Queensland, Cairns is prone to tropical cyclones. For this reason, we make sure to provide high quality mountings for the solar systems installed in this area.
The Silhouette solar power panels feature advanced cell technology and superior ‘low-light’ and ‘high-heat’ performances which result in a consistently high yield. The solar power products depend a lot on the geographical location, places like Darwin will produce much more solar power compared to Brisbane. The 10kW solar power system is best for you if your per day consumption is high, 10kW Solar power system can power your home or business. Solar panels should be installed in areas with minimal shading for maximum efficiency, ideally on a north-facing roof in Brisbane. If there’s significant shading or your roof needs repairs, those issues should be addressed first to avoid affecting the panels’ performance.
With the potential for significant savings and government rebates, it’s time to take a closer look at what a 4 kW solar system entails and the 4 kW solar system price. In this blog post, we will explore factors that affect the cost, output, and savings of a solar system and how to assess your energy needs to make the most of this investment. Our solar battery solutions allow you to store excess solar energy for use during outages or peak hours. They provide energy security, reduce reliance on the grid, and increase overall savings.
To qualify for most rebates, including the Battery Booster program, you must use Clean Energy Council (CEC) accredited installers. This guarantees that the installation meets the necessary standards for safety and efficiency, crucial for accessing all available incentives. To put it in perspective, a person in Brisbane Queensland installing a typical 6.6kW Solar system would receive about 54 small scale technology certificates STCs. Based on the current STC market value of $39.90, you would receive $2,155 in rebates.
The component of your system most likely to break down is the inverter. You may find that a cheap inverter breaks down far earlier than anticipated, perhaps around the 5-year mark. The cost to replace the inverter could range between $1,000 - $1,800 depending on its quality.
Our energy costs are zero, in fact we’re making money from our solar power now. I have just installed a second Arise Solar 6.6kw system comprising DAS Solar panels and Jinko Inverter and 15KW Jinko battery. The latest functionality of the Ap to understand the power being produced, consumption and battery status is very easy, I am now 100% self sufficient in energy and exporting excess power. That’s the difference between one of the best solar companies in Brisbane that takes pride in their work and a company that aims to sell solar power systems at the cheapest price in the market. A handy checklist for planning solar panels, installation and connecting to the grid.
For many Aussies, solar batteries have long been a smart idea in theory, but financially frustrating in practice. That’s changing with the federal battery rebate dropping prices 30-40%. If you’re looking for a reliable, efficient, and affordable solar solution, Sunmate Solar is the way to go. They provide expert installation, high-quality products, and excellent customer service, ensuring that your solar system works at its best for years to come. Often for single-phase connections the limit is a 5kVA inverter which can accommodate 6.6kW of solar panels.
If you consider a 13kW solar system with battery price will add approximately $10,000 to $15,000. As we mentioned above, a 13kW Solar System will produce somewhere between kWh each day. This figure is significantly higher than the average Australian household consumption, which is around 18kWh to 22kWh of electricity each day. "We need things like these urban renewable energy zones, as well as solar for renters, to enable the large-scale solutions that we need to bring energy prices down for people," she said. ""The ACCC will be watching carefully and actively monitoring consumer complaints. We will hold solar and battery installers, retailers and suppliers accountable to ensure they comply with Australia's consumer laws."
You are selecting a high-quality system from a reputable installer company. It may be that site issues increase the cost of installation, or you have opted for microinverters or power optmisers that have increased the cost of your solar panels. Take comfort in the extended warranties that cover the entire system and high performance of your solar panels.
When done correctly, solar can be a simple procedure, and accurately determining your payback period is critical to knowing how much you will save over the years you have solar. Orange represents the maximum solar system size for the amount of kwh your home consumes. Every year, Brisbane homeowners spend thousands of dollars on a 6.6kw solar system.
