List of Western Australia Solar Rebates and Incentives in 2025

Introduction

Are you considering installing solar panels for your home or business in Western Australia? With abundant sunshine and several financial incentives, WA offers a great environment for solar energy investment. While WA does not have state-specific solar rebates, residents can take advantage of federal incentives and other programs that significantly reduce costs and maximize savings.

Federal Government Incentives

The Australian federal government provides substantial support for solar installations through the Small-scale Renewable Energy Scheme (SRES). This scheme offers Small-scale Technology Certificates (STCs), which act as a financial incentive for installing solar systems under 100kW. Here’s how it works:

• STCs Calculation: The number of STCs you receive depends on your system size, location, and the deemed period of electricity generation (until 2030). For example, a 6.6kW system in Perth might generate around 90 STCs in 2025.
• Value: Each STC is traded on a market, typically valued between $35-$40, reducing your upfront cost by thousands. For a 6.6kW system, this could mean a $3,000-$3,600 discount.
• Process: Solar installers often handle STC paperwork, applying the discount directly, so you pay less out-of-pocket.

"The STC scheme is a game-changer for solar affordability, turning sunshine into real savings for WA households." — Dr. Michael Evans, Renewable Energy Expert

In 2025, the STC scheme is still active, though the number of certificates decreases annually as the program phases out by 2030. Acting sooner maximizes your benefits.

Feed-in Tariffs in Western Australia

Feed-in tariffs (FiTs) reward solar owners for excess energy fed back into the grid. In WA, the Distributed Energy Buyback Scheme (DEBS) is the primary program in 2025:

• Rates: As of 2025, DEBS offers 10 cents per kWh for exports between 3 PM and 9 PM (peak), and 3 cents per kWh at other times (off-peak).
• Eligibility: Available to Synergy and Horizon Power customers with systems up to 5kW (single-phase) or 27kW (three-phase).
• Savings: A typical household exporting 10kWh daily (mixed peak/off-peak) could earn $300-$400 annually, offsetting energy bills.

Unlike some states, WA’s FiT rates remain competitive, encouraging solar adoption without state-specific rebates.

Interest-Free Loans and Local Programs

While not a rebate, the WA government partners with local councils and utilities to offer interest-free loans or payment plans for solar installations in 2025:

• Solar Switch Program: Available in select Perth suburbs, this offers up to $10,000 interest-free over 10 years, covering solar and battery systems.
• Eligibility: Varies by region—check with your local council or Synergy.

These programs lower the financial barrier, making solar accessible even without upfront cash.

Tips to Maximize Incentives

To get the most out of these incentives:

1. Size Your System Right: A 6.6kW system with a 5kW inverter balances STC benefits and DEBS eligibility.
2. Time Your Usage: Use energy during the day and export during peak FiT hours (3 PM-9 PM).
3. Combine with Batteries: Store excess energy to use at night, reducing reliance on the grid.
4. Get Quotes: Compare installers to ensure STC discounts are applied fully.

"Solar isn’t just about going green—it’s about smart economics for WA families in 2025." — Lisa Tran, Solar Installation Specialist

Conclusion

Western Australia in 2025 remains a prime spot for solar investment, thanks to federal STCs, competitive feed-in tariffs, and local financing options. While state rebates are absent, these incentives can slash installation costs by 30-40% and deliver ongoing savings. Whether you’re a homeowner or business owner, now’s the time to harness WA’s sunshine and turn it into savings.
