Last updated: June 2025 | Reading time: 5 minutes

Western Australia is basking in sunshine and boasting some fantastic incentives for homeowners looking to switch to solar power. With over 500,000 Western Australians already embracing solar, accounting for a remarkable 45.89% of households, it's clear that the benefits are shining through. A major driver for this solar uptake is the availability of solar rebates, and 2025 is shaping up to be a great year to take advantage. To delve deeper into the nuances, check out our Complete Guide for a comprehensive overview.

Why Go Solar in WA?

WA's abundant sunshine hours translate to high-value solar rebates, making panel prices competitive, particularly in areas like Perth. These savings, coupled with increasing energy costs, make solar an increasingly attractive investment. Furthermore, starting July 1, 2025, WA residents will have access to the WA home battery rebate, opening up even greater opportunities for energy independence. These initiatives are expected to boost the state’s renewable energy contribution, currently at 17.6% of total electricity generation.

Beyond solar panels and batteries, the WA government is also incentivizing electric vehicle adoption, creating a greener future for the state.

Understanding the WA Solar Rebate Landscape

This guide explores the incentives available in WA, explains how you can calculate potential savings, and outlines the simple process for claiming these rebates.

The Federal Solar Rebate: A National Incentive for WA Homes

The good news is that the federal solar rebate is available to all eligible WA residents who purchase new solar panels. This significantly reduces the upfront cost of your solar system. When you work with a solar installer, they will provide a quote that reflects the net price of the system, including the deduction for the solar rebate.

How is the Rebate Calculated?

The size of your rebate depends on two primary factors:

  • Sunshine Hours in Your Location: WA benefits from a high number of sunshine hours compared to some other states, like Tasmania. This generally translates to a higher rebate.
  • System Size: The larger your solar system, the larger the potential rebate (up to eligible limits).

Your location falls into a specific rebate zone. In this zone, you’re allocated a certain number of Small-scale Technology Certificates (STCs) based on anticipated sunshine hours. This certificate number is then multiplied by the size of the system you choose. After your system is installed, your solar company will trade these STCs on your behalf, providing you with the upfront rebate.

Essentially, the more sun your location gets and the larger your system, the greater the potential rebate.

How Much Can You Save?

The WA solar rebate can significantly reduce the cost of a new solar system, typically by 25% to 30%. To illustrate, consider a 6.6kW system in Southern WA. (Note: A table with example pricing would typically be included here, but without specific pricing data, I cannot accurately populate it.)

Claiming Your WA Solar Rebate: A Simple Process

Claiming your solar rebate in WA is straightforward. The most important thing is to ensure you meet the eligibility requirements. A reputable solar company can help you navigate these requirements to make sure you qualify. Here's a simplified overview of the process:

  1. Engage a Reputable Solar Company: This is crucial. They will handle the complexities of the rebate process.
  2. System Design and Quote: Discuss your energy needs and budget with the solar company to design the ideal system for your home. The quote should clearly show the net price after the rebate is applied.
  3. Installation: Once you approve the quote, the solar company will install your system.
  4. STC Assignment: You'll assign your STCs to the solar company.
  5. Rebate Applied: The solar company will trade the STCs and deduct the rebate amount from the final cost of your system.

Key Takeaways

  • Abundant Sunshine = Higher Rebates: WA's sunshine makes solar a smart investment.
  • Federal Rebate Available: Reduces the upfront cost of your system.
  • Professional Installation is Key: Choose a reputable installer to ensure eligibility and a smooth process.
