How to Apply for Solar Panel Rebates in WA (Western Australia) in 2025

As the demand for clean, renewable energy continues to grow, 2025 presents another excellent opportunity for homeowners and businesses in Western Australia (WA) to invest in solar power. To make solar energy even more accessible, various rebates and incentives are available to help reduce the upfront cost of solar panel installation.

In this guide, we explain how to apply for solar panel rebates in WA, what rebates are currently available in 2025, and what you need to know before starting the application process.

What Solar Rebates Are Available in WA in 2025?

1. Small-scale Technology Certificates (STCs) – Federal Rebate

The most widely accessed incentive is the federal STC rebate under the Small-scale Renewable Energy Scheme. This rebate applies across all of Australia, including WA.

• How it works: When you install an eligible solar system under 100kW, you receive STCs based on the size of the system and your location (sunlight zone). These certificates are traded for a discount on your installation price.
• In 2025: The number of STCs is reducing every year until 2030, so the rebate value decreases over time. However, it still covers up to $2,000–$3,000 for a typical 6.6kW system in Perth.

2. Distributed Energy Buyback Scheme (DEBS) – WA Government

While not a traditional rebate, DEBS offers payments for excess solar energy exported back into the grid.

• Eligibility: Residential and small business customers with systems up to 5kW inverter capacity.
• Rates (2025): Check with Western Power or Synergy for updated DEBS rates. In 2024, rates were higher during peak times (3 PM to 9 PM).

Step-by-Step Guide: How to Apply for Solar Rebates in WA

Step 1: Choose a CEC-Accredited Solar Installer

To qualify for STCs and other rebates, your solar installer must be accredited by the Clean Energy Council (CEC). Make sure your installer provides Tier 1 solar panels and meets all installation standards.

Step 2: Get a Solar Quote That Includes STC Rebate

Reputable solar companies in WA usually deduct the STC rebate upfront, so you don’t need to apply separately. The quote should show how much you’re saving through the rebate.

Step 3: Sign the Paperwork

You’ll need to sign the assignment form that allows your installer to claim the STCs on your behalf. This is standard procedure and handled during your system purchase.

Step 4: Installation and Connection

Once your system is installed, your installer will submit all necessary documents to create and trade the STCs. If you’re eligible for DEBS, they’ll also arrange a meter upgrade (if required).

Step 5: Monitor Your Savings

After installation, monitor your solar generation and export to maximise DEBS payments and reduce your electricity bills. Many systems come with mobile apps or online portals to help you track performance.

Additional Tips for Solar Rebate Success

• Check Warranty and Support: Look for at least 10-year warranties on inverters and 25 years on panels.
• Understand Payback Time: A good-quality system in WA typically pays for itself in 3–5 years.
• Ask About Battery Rebates: While WA currently doesn’t offer a state-wide battery rebate in 2025, watch for any local council or pilot programs that may provide incentives.

Taking advantage of solar panel rebates in WA is straightforward, especially with a trustworthy solar provider handling the application for you. With the STC rebate still available in 2025 and rising electricity costs, now is the perfect time to go solar and enjoy long-term savings.
