Government Solar and Battery Rebates WA: 2026 Guide

Electricity prices are rising quickly across Western Australia. Because of this, many Perth homeowners are now looking for solar and battery rebates WA to help reduce their monthly bills.

Fortunately, several government-backed incentives are available right now. These programs can significantly reduce your upfront investment costs. In this guide, we explain how to maximize your savings using verified 2026 sources.

☀️ Federal Solar and Battery Rebates WA

Small-scale Renewable Energy Scheme (SRES)

The primary support for renewable energy is the federal government’s SRES program. Basically, this program uses Technology Certificates (STCs) to provide a point-of-sale discount.

Consequently, this reduces the total cost of your solar system immediately. Furthermore, your installer handles all the paperwork for you.

• ✔️ Available state-wide: This applies from Perth to the Kimberley.
• ✔️ Automatic Discount: Your installer applies this to your quote automatically.
• ✔️ Size-Based: Savings depend on your location and system size.

💰 Typical Savings

For example, most Perth households save between $2,200 and $3,400 on a 6.6kW system. In addition, the solar and battery rebates WA residents claim now include an extra $3,000+ for battery storage units under the federal framework.

🔋 WA State Residential Battery Scheme

Local Incentives for 2026

As of 2025, WA households can access state-specific funding. The WA Residential Battery Scheme launched on 1 July 2025 to help lower home energy costs. Notably, this is one of the most generous state schemes in the country.

• ✔️ Stackable: You can combine federal STCs with the state battery rebate.
• ✔️ Lower Costs: Both incentives reduce your upfront installation price.

💰 Estimated Savings

Specifically, Synergy customers can save up to $5,000. Meanwhile, Horizon Power customers can save up to $7,500 on a 10kWh battery. Typically, these solar and battery rebates WA cover roughly 40% of the total cost.

⚠️ Important Requirements

However, you must join a Virtual Power Plant (VPP) to get the WA state rebate. Additionally, a new tiered structure starts on 1 May 2026 for large systems. Finally, eligible households can access interest-free loans of up to $10,000 through the state government.

🔥 Heat Pump & Solar Hot Water Rebates

Hot water systems use a lot of energy. For this reason, they qualify for significant rebates under federal and state programs.

Federal & State Support

First, your installer applies the federal STC discount at the point of sale. Next, the WA Energy Upgrade Subsidy offers an extra $500 to $1,000 for high-efficiency heat pumps. Lastly, concession card holders may receive up to $1,500 in total subsidies.

✅ Checklist: 5 Steps to Maximising Savings

1. Check Your Needs: Decide if you need solar, a battery, or both.
2. Verify VPP Status: Confirm you are willing to join a VPP for the state rebate.
3. Use Approved Gear: Only approved components qualify for discounts.
4. Lock in Dates: Act before 1 May 2026 to get the best rates.
5. Claim Your “Stack”: Ensure your installer shows both discounts on your quote.
