Why Go Solar in WA?
Beyond contributing to a greener future, installing solar panels in Western Australia offers significant financial benefits. The upfront cost is reduced through rebates, and long-term savings on your electricity bills make solar a smart investment. As a further incentive, from July 1, 2025, residents will also be able to access the WA home battery rebate, making energy independence more achievable than ever. These rebates should see an increase to the 17.6% of the state’s electricity that is currently generated from renewable sources.
Understanding the Solar Rebates in WA
The good news is, the Australian Government provides a solar rebate to all eligible WA residents who purchase new solar panels. However, it's important to understand how it works.
How the Rebate is Calculated
The size of the rebate you receive depends on two key factors:
- Your Location: Western Australia is divided into zones based on average daily sunshine hours. Regions with higher sunshine hours receive a larger rebate.
- System Size: The larger your solar panel system, the larger the potential rebate.
Small-Scale Technology Certificates (STCs)
The federal solar rebate operates through a system of Small-Scale Technology Certificates (STCs). Most of Western Australia benefits from a high number of sunshine hours, so the rebate is higher than it is in some other states, like Tasmania.
Here's a simplified explanation:
- Your location falls into a specific zone, which determines the number of certificates allocated to you based on available sunshine hours.
- This number is then multiplied by the size of the solar system you choose.
- Once your solar panel system is installed, your solar company will trade these certificates (STCs) on your behalf. The value of these STCs is then deducted from the upfront cost of your solar system.
How Much Can You Save?
The WA solar rebate can significantly reduce the cost of a new solar system, typically by between 25-30%.
Example Rebate Calculation (Southern WA):
The following table shows the rebate and net price of a 6.6kW system in southern WA. Please note this is an example, and actual rebates may vary.
| System Size | Rebate Estimate | Net System Price (Estimate) |
|---|---|---|
| 6.6kW | $X,XXX | $Y,YYY |
(Replace $X,XXX and $Y,YYY with approximate figures based on current market conditions. These values change often, so don't provide hard numbers that will quickly become outdated. Mention instead that the reader should use a solar rebate WA calculator for an accurate estimate.)

Claiming Your Solar Rebate: A Step-by-Step Guide
Claiming the solar rebate in WA is relatively straightforward, especially when you partner with a reputable solar company. They will handle most of the paperwork and calculations for you.
Here's a general outline of the process:
- Engage a Solar Company: Choose a reputable solar installer with experience in Western Australia.
- System Design and Quote: The solar company will assess your energy needs and provide a quote for a suitable solar system. The quote should clearly show the net price of the system after the solar rebate has been applied.
- Installation: Once you approve the quote, the solar company will install your solar panel system.
- STC Assignment: You'll likely need to sign a form assigning your STCs to the solar company. They will then trade the STCs and deduct the value from your system cost.
Eligibility Requirements
While claiming the solar rebate is simple, you need to meet certain eligibility requirements. A good solar company will guide you through these requirements. Common criteria include:
- The solar system must be new and installed by a Clean Energy Council (CEC) accredited installer.
- The solar panels and inverters must be approved by the Clean Energy Council.
- You must connect the solar system to the electricity grid.
Other Incentives in Western Australia
Beyond the federal solar rebate, the WA government also offers additional incentives, including:
- WA Home Battery Rebate (Available from July 1, 2025): This rebate helps reduce the cost of purchasing and installing a home battery system, allowing you to store excess solar energy for later use.
- Electric Vehicle (EV) Incentives: The WA government offers a range of incentives to encourage the adoption of electric vehicles, further promoting sustainable energy solutions. Check the relevant government websites for updated incentives and eligibility criteria.
