WA Battery Scheme 2026: Complete Eligibility Checklist and Application Guide
Quick Answer: The WA Residential Battery Scheme offers up to $1,300 for Synergy customers and up to $3,800 for Horizon Power customers toward a home battery installation. To be eligible, you need an existing or new solar system, an approved battery product, an approved installer, and your home must be your primary residence. Combined with the federal Cheaper Home Batteries rebate, Perth homeowners can save $4,000-$7,000+ on battery storage.
The WA Battery Scheme has made home battery storage genuinely affordable for the first time. But understanding whether you qualify — and maximising your savings — requires navigating eligibility criteria, approved product lists, and stacking multiple rebates correctly.
Eligibility Checklist
You must meet ALL of the following criteria to qualify for the WA Residential Battery Scheme:
- Primary residence — The property must be your main home. Investment properties and rental properties don’t qualify.
- Solar system — You must have an existing solar system OR install solar at the same time as the battery.
- Approved battery — The battery must be on the scheme’s approved product list. Most major brands qualify (Tesla, BYD, Sungrow, Alpha ESS, Huawei).
- Approved installer — Installation must be completed by an approved vendor registered with the scheme. Not all solar companies are registered.
- VPP readiness — The battery must be capable of participating in a Virtual Power Plant program (most modern batteries meet this).
- Grid-connected — Off-grid systems don’t qualify for this scheme.
How Much Can You Save?
| Customer Type | State Rebate | Federal Rebate* | Combined Saving |
|---|---|---|---|
| Synergy (Perth metro) | Up to $1,300 | ~$3,000-$3,400 | ~$4,300-$4,700 |
| Horizon Power (regional) | Up to $3,800 | ~$3,000-$3,400 | ~$6,800-$7,200 |
*Federal Cheaper Home Batteries rebate via STCs. Exact amount depends on battery capacity and installation date (STC factor drops from 8.4 to 6.8 in May 2026).
Interest-Free Loan Option
If your household income is under $210,000, you may also qualify for an interest-free loan of $2,001-$10,000 repayable over 3-10 years. This is on top of the rebate — meaning you could get a 10kWh battery with a rebate AND spread the remaining cost interest-free.
Important: The interest-free loan is means-tested. You’ll need to provide income documentation. The rebate itself is NOT means-tested — every eligible homeowner gets the same rebate regardless of income.
Step-by-Step Application Process
- Confirm eligibility using the checklist above.
- Get a quote from an approved installer (Talk Energy is an approved vendor).
- The installer applies for the rebate on your behalf before installation.
- Once approved, the rebate is deducted from your invoice — you pay the reduced price.
- Installation is completed and registered with the scheme.
- If applying for the interest-free loan, your installer helps you submit the loan application simultaneously.
Common Reasons Applications Get Rejected
- Property is not the applicant’s primary residence
- Battery not on the approved product list
- Installer not registered as an approved vendor
- Existing battery already installed (no double-dipping)
- Off-grid systems (separate programs may apply)
Frequently Asked Questions
Can I get the battery rebate if I already have solar?
Yes — the WA Residential Battery Scheme is specifically designed for homeowners adding batteries to existing solar systems, as well as new solar + battery installations. Your existing solar system doesn’t need to be a specific size or brand. The only requirement is that you have a functioning grid-connected solar system at the time of battery installation.
How long does the rebate application take?
Typical approval time is 2-4 weeks from application submission. Your approved installer submits the application before scheduling installation. Once approved, installation can usually be completed within 1-2 weeks. The entire process from initial quote to operational battery typically takes 6-10 weeks.
Will the WA Battery Scheme run out of funding?
The scheme has 100,000 rebates available and launched in July 2025. As of early 2026, significant funding remains. However, the federal Cheaper Home Batteries STC factor drops in May 2026, reducing the federal portion. If you’re considering a battery, acting before May 2026 maximises your combined savings.
