Western Australia is leading the nation in residential solar adoption, and the introduction of the WA Residential Battery Scheme on 1 July 2025 will further accelerate this trend. With a state government commitment of $337 million, the scheme is set to support up to 100,000 households by offering significant rebates and no-interest loans. Residents serviced by Synergy, this initiative presents a major opportunity to install solar battery systems Perth at reduced upfront costs.
Background and Scheme Objectives
The WA Residential Battery Scheme is supported by both the State Government and the Federal Government’s Cheaper Home Batteries Program. Scheduled to commence on or before 1 July 2025, the scheme aims to reduce cost-of-living pressures, support local clean energy jobs, and encourage battery adoption across Western Australia. Participating households will be required to join a Virtual Power Plant (VPP), allowing them to export stored energy to the grid and support WA’s energy network with approximately 1GWh of decentralised capacity. VPP participation may also provide additional income through higher feed-in tariffs.
Rebate Structure
The rebate amounts vary based on the electricity provider:
- Synergy customers (Perth): $130 per kWh, capped at $1,300 per household.
- Horizon Power customers (regional areas): $380 per kWh, capped at $3,800 per household.
For example, a 10kWh battery would be eligible for the full rebate in both regions.
In addition to the state rebate, the federal Cheaper Home Batteries Program will cover approximately 30% of the battery installation cost. Based on an average battery cost of $330 per kWh, this equates to around $2,574 for a 10kWh system.
Combining both schemes:
- Perth households (Synergy) may receive up to $5,000.
- Regional households (Horizon Power) may receive up to $7,500.
These rebates are designed to ensure economic value for energy storage while supporting household energy independence.
No-Interest Loan Offering
To further reduce financial barriers, the scheme includes no-interest loans for eligible applicants:
- Loan amount: Up to $10,000.
- Repayment term: Up to 10 years.
- Eligibility: Households with a combined annual income of less than $210,000.
- Coverage: Applicable to batteries, inverters, and solar panels if installed as a package.
The loan program is backed by a $200 million fund, intended to support up to 20,000 households in the initial rollout.
Eligibility Requirements
To access rebates and loans, households must meet the following conditions:
- Installations must occur on or after 1 July 2025.
- Participation in a Virtual Power Plant is mandatory.
- Only batteries listed on an approved equipment list (to be published closer to the launch date) will qualify.
- The property must be a residential address, including home businesses.
It is estimated that approximately 80% of WA households will be eligible for the no-interest loans.
Preparation Tips for Perth Residents
To prepare for the scheme, Perth households should:
- Ensure their current solar system is compatible with battery storage and ideally includes a hybrid inverter.
- Consider pre-ordering a battery system to ensure timely access once the scheme launches, while avoiding early installation.
- Regularly check for updates on approved suppliers and product lists via Energy Policy WA.
- Avoid any installation before 1 July 2025, as these systems will not be eligible for financial support, per Consumer Protection WA.
Industry Perspective and Long-Term Benefits
According to the Clean Energy Council, solar and battery systems can help households save over $900 per year on electricity bills. At a network level, the widespread adoption of batteries and VPP participation could reduce infrastructure costs by approximately $190 million by 2030.
The scheme also supports local industry growth by driving demand for certified installers, battery system suppliers, and energy management services, reinforcing WA’s leadership in the renewable energy sector.
Complementary Programs
The WA Residential Battery Scheme works alongside other established incentives:
- The Small-scale Renewable Energy Scheme (SRES), which offers upfront discounts on solar panel installations.
- The Distributed Energy Buyback Scheme (DEBS), which provides feed-in tariffs for Synergy customers who export solar energy to the grid.
These programs collectively enhance the financial and environmental benefits of adopting solar energy systems in Western Australia.
Summary Table
| Category | Synergy Customers (Perth) | Horizon Power Customers (Regional WA) |
| State Rebate (per kWh) | $130 | $380 |
| Maximum State Rebate | $1,300 | $3,800 |
| Federal Rebate (approx. 30%) | $2,574 | $2,574 |
| Combined Maximum Rebate | Up to $5,000 | Up to $7,500 |
| No-Interest Loan (10-year term) | Up to $10,000 | Up to $10,000 |
Conclusion
The Solar Battery Rebate Perth initiative provides a significant opportunity for households to reduce energy bills, increase energy independence, and contribute to the state’s renewable energy goals. With up to $5,000 in combined rebates and an optional $10,000 no-interest loan, eligible Perth residents can now make battery storage more financially viable. As the scheme begins on 1 July 2025, early preparation, correct system planning, and timely application will be critical to maximising benefits. This initiative represents a practical step towards a smarter, more sustainable energy future for Western Australia.
