Three Rebates. One Loan.

Here's The Full Picture

Perth homeowners installing solar and a battery in 2026 can combine multiple incentive layers, then use a no-interest loan to cover the remaining balance.

A typical 6.6 kW solar system in Perth can still receive around $1,600 in incentives when it uses CEC-approved products and is installed by an SAA-accredited installer.

A New Home Battery

The Cheaper Home Batteries Program now supports battery storage through to 2030 but rebates decrease over time. Install before 1 May 2026 and rebates sit at roughly $300 per kWh, saving around $3,000 on a typical 10 kWh battery. After that date, the value reduces.

WA State Rebate

Extra WA-only Savings

On Top Of The Federal Rebate

Launched on 1 July 2025, the WA Residential Battery Scheme provides a state rebate for home batteries that can be combined with the federal Cheaper Home Batteries Program, with funding for up to 100,000 installations.

Scannable Yes / No

Am I Eligible?

A quick self-check. If you can answer yes to the core items below, you are aligned with the federal plus WA rebate stack. The no-interest loan has its own additional income condition.

Do you own and live in your own home?

The rebates and loan are available to owner-occupiers. Landlords and tenants may have different pathways.

Is your combined household income below $210,000?

This is the income eligibility cap for the WA no-interest loan. The federal battery rebate and STCs have no income test.

Is your home in a Synergy or Horizon Power area?

Synergy covers the Perth metro/SWIS region. Horizon serves regional WA. Both administer the WA Battery Scheme.

Do you currently have a solar system, or are you installing one alongside the battery?

Battery rebates are primarily designed for solar-plus-battery installations. Battery-only is also possible in some cases.

Are you willing to join a Virtual Power Plant (VPP)?

VPP participation is a condition of the WA battery rebate under the current scheme rules.

Do you have a recent electricity bill showing your annual usage?

The loan assessment will look at your address, credit history, and ability to repay.
