How Much Do Solar Panels Cost in Australia? 2025 Guide

Notably, our best-selling product is the GEH series of single-phase hybrid inverters. Investing in a high-quality inverter can help ensure the long-term performance and reliability of your 6.6 kW solar system in Brisbane. It is important to note that the Bloomberg Tier 1 ranking assesses manufacturers of photovoltaic panels, rather than specific module tests. Nevertheless, the stringent criteria imposed by investors and banks prioritise the safety of investments. Therefore, panels from ranked manufacturers are synonymous with high quality and low failure rates.
Yes—solar batteries like the Tesla Powerwall 3 come with blackout protection, which means you’ll keep the lights (and fridge, Wi-Fi, and more) on even when the grid goes down. It’s one of the biggest benefits of adding a battery commercial solar panel queensland to your solar setup. While feed-in tariffs (FiTs) have dropped, self-consumption is now key. That’s where solar batteries shine—they store excess energy for you to use later, rather than selling it back at a low rate. With tailored setups, expert advice, and reliable tech, our solar and battery solutions deliver long-term savings for Sunshine Coast homeowners—no matter your energy needs. In this guide, I break down the real costs, explain which rebates are available and how they affect your payback.

Made in Singapore, REC Alpha Pure Series panels have a new, design that boosts panel output to higher levels, but coming in at a ‘standard’ physical size module. The REC Alpha Pure’s reach their superb performance by using Half-cut cell technology. In cases where there is shading, then the best option is to use shade tolerant panels like these.
SolarWide helps Sunshine Coast households beat rising energy bills with reliable solar and battery systems tailored to your usage. If you are Buyer #1 (i.e. buying solar and batteries at the same time), using a hybrid inverter can reduce your total cost because your solar and battery share one inverter. The savings can be around $1,000 compared to retrofitting energy storage to existing solar.
It is estimated that a 4 kW solar system may provide up to $1,708 in savings per year when using time-of-use billing or $1,480 in savings when using a flat rate for power. These savings can vary depending on factors such as location, electricity rates, and usage. If you buy a more efficient solar panel, like a 400 W panel, you will only need 10 panes to make up 4,000 W or 4 kW.

Maximise your solar consumption and offer backup power right in a blackout situation. Did you know that about 45% of Queenslanders are considering purchasing an electric vehicle (EV) within the next five years? Installing a home battery lets you charge your EV overnight and sell excess stored electricity back to the grid. This gives you the flexibility to choose what suits your lifestyle and take advantage of the current feed-in tariff. The Small-scale Renewable Energy Scheme (SRES) provides upfront discounts in the form of STCs (Small-scale Technology Certificates).
In Queensland, installing a solar hot water system can save households between $250 and $700 annually on energy bills, depending on hot water usage and the type of system. These systems use solar energy to heat water, reducing reliance on traditional electricity or gas sources, and making them both cost-effective and eco-friendly. According to our own data from nearly 300 business cases compiled in 2023, payback periods for appropriately sized commercial-scale solar systems in Australia are around 2 years on average. This factors in both the government STC rebate and the current tax incentives for depreciating solar systems.

You should be able to figure out roughly how many kWh you use per day on average by looking at your old electricity bills. As a rule of thumb, the average Australian home uses between 15 and 25kWh of energy per day. The federal STC rebate is available for the installation of new solar panels in Brisbane. The new federal home battery rebate is also available on both additions to existing panel systems and new hybrid systems. At Ads Solar, we specialize in providing custom 13.2 kW solar battery solutions for Australian homes and businesses.
However,  in Brisbane, nearly every combination of panel angle and orientation can generate enough solar electricity to deliver great savings. Your budget will be a significant factor in selecting the right solar battery system. While high-end options like Tesla Powerwall and LG Chem provide excellent performance and reliability, they also come with a higher price tag.
The Seraphim S4 collection incorporates 182mm large-size silicon wafers with PERC, multi-busbar, half-cell modern technologies, and high-density encapsulation. Innovation integration allows the S4 series to boost efficiency by as much as 21.1% and optimum power to 540W. In the case of a budget brand system, the panels will only make up about 25% of the system cost. However, when we look at a 10 kW system consisting of the top-of-the-line REC Pure Alpha-RX, the panels take up almost 37% of the entire system cost. Always, Always check the warranty terms on the products you are buying, usually the longer the term the better the products. The aim of the Battery Storage Price Index is to assist homeowners assess whether batteries are worth their while without having to engage with battery vendors before they are ready.

You can currently claim rebates on 10 years of operation when calculating your government solar rebate. Up until 2030, the number of operating years will decrease by one yearly. With Power Purchase Agreements (PPAs), you pay for the electricity generated by your battery at a set rate, often lower than traditional energy prices. This option allows you to benefit from solar and battery systems without the need  for ownership. However, PPAs require a long-term commitment and do not offer ownership benefits or eligibility for rebates. Queensland, known for its sunny climate, has some of the best solar incentives.
Brisbane has abundance of sunshine; hence it is considered as one of the best places for solar panel system installation. Considering an average of 4-5 hours of daily sunshine; a 6.6kW solar system in Brisbane is expected to generate around 24kW – 26kW per day. We can arrange a solar battery installation for you in Brisbane, at a great price, installed correctly.
We’re also continually voted among the top 5 solar companies in Australia on SolarQuotes. We, like most Brisbane commercial solar companies, quote solar with the STCs already discounted off the price. So a 30kW solar system will cost around $45,000, but we will quote and charge you about $30,000. While it’s technically not called a  rebate, you can receive two financial incentives to install solar on a commercial building. If you don’t already have solar power installed, we can still help you.
