WA’s Solar Battery Rebate launches on 1 July 2025, offering rebates of up to $7,500 and no-interest loans to support home energy storage. Here’s how to qualify, maximise your savings, and prepare early.
The rebate is expected to significantly improve the solar battery payback period for customers in WA.
Overview of the WA Home Battery Rebate Program
The WA Government has committed $337 million to help households install battery storage systems. Under the Residential Battery Scheme, eligible homeowners on the Synergy and Horizon Power networks can access:
- Up to $1,300 rebate for Synergy customers ($130/kWh for up to 10 kWh)
- Up to $3,800 rebate for Horizon Power customers ($380/kWh for up to 10 kWh)
- Interest-free loans up to $10,000 for households with less than $210,000 income
The rebate is expected to be delivered as an upfront discount. You are not limited to a 10kWh battery, but rebates apply only to the first 10kWh of capacity.
But funding is limited. The rebate is restricted to 100,000 households across WA — from over 900,000 dwellings.
We recommend making a plan now to have a battery installed from 1st July.

Why Are Horizon Customers Getting More?
Horizon Power services regional and remote WA, where electricity infrastructure is more expensive and less reliable. Higher rebates reflect the greater cost of batteries in these off-grid or microgrid locations, offering improved energy security and cost savings.
What Can the Interest-Free Loan Cover?
Alongside rebates, the scheme includes means-tested loans to help eligible households afford a system. These loans can be used for:
- Battery-only systems
- Combined solar + battery packages
- New or replacement solar panels (only when bundled with a battery)
Interest-Free Loan Details
- Amount: $2,000 – $10,000
- Term: Up to 10 years
- Eligibility: $210,000 maximum household income
The rebate is not income-tested, meaning any eligible household can apply — but loans will only be available to lower- and middle-income earners.
Eligibility Criteria for WA Battery Rebate
To qualify for the scheme, applicants must:
- Be a resident of Western Australia
- Be a customer of Synergy or Horizon Power
- Install new equipment only — second-hand systems are not eligible
- Battery must participate in a Virtual Power Plant
- Battery must be on WA Government’s approved battery list which has not been released (TBC)
- Use a WA-based accredited retailer or installer
Also eligible:

What Are VPPs and Why Do I Need To Join One?
A Virtual Power Plant (VPP) is a ground of interconnected batteries that can be that can be controlled remotely by the VPP operator, usually to provide services to the grid. Typically homeowners are paid a fee or offered a bonus feed in tariff to participate in VPPs making it more worthwhile than using their energy within their home.
To participate in a VPP a battery must:
- Be connected to the internet
- Be able to respond to signals from the grid
The company who installs your battery will be able to support you in connecting to a VPP.
The intent of the WA government is for the 100,000 batteries they intend to subsidise to help stablise the WA electricity grids along with benefit individual homes. Batteries operating in a VPP can help stabilise volatility in voltage and frequency in the grid and handle spikes in demand. Overall this is expected to lead to lower electricity prices for all homes, not just those who install batteries.
How to Prepare for the WA Battery Rebate
Rebate demand will likely exceed supply. Follow these steps to be installation-ready before the rush.
1. Install Solar (or Plan to Bundle)
Homes with existing solar will be in a stronger position to qualify. If you don’t already have panels, install them now or bundle them with a battery to maximise savings.
- Homes with existing solar are more rebate-ready
- Bundling solar and batteries can maximise savings
2. Choose a Hybrid Inverter
A hybrid inverter supports both solar input and future battery integration. It simplifies system expansion and avoids delays tied to grid approval.
- Hybrid inverters simplify battery integration
- DC-coupled setups can fast-track approval and installs
3. Pre-Order Your Battery
To secure stock and fast-track compliance, pre-order your battery in advance. With only 100,000 rebates available, early preparation ensures you’re at the front of the line.
- With only 100,000 spots available, early pre-ordering secures stock
4. Work With a Trusted WA Installer
The rebate requires WA-based installers — but a local company also offers:
- Faster turnaround
- Localised aftercare and warranty support
- Knowledge of WA compliance standards
Avoid national operators chasing rebate programs. Choose a provider with proven experience in WA.
Should You Wait For 1st July To Install A Battery
The federal battery rebate is available to batteries installed prior to 1st of July that haven’t been ‘turned on’ yet. Installing a battery early could mean avoiding delays from supply and installer shortages once the scheme takes off.
However the full details of the WA battery rebate haven’t been announced yet. Importantly they are yet to release a list of batteries that are approved under the scheme.
Under consumer protection law a solar installation company must release you from any contract if they have made false promises about the WA Battery Rebate.
Combining the WA and Federal Solar Battery Rebates?
Yes, the WA Government has confirmed that eligible households will be able to combine both the WA Home Battery Rebate and the Australian Governments Federal Solar Battery Rebate to significantly reduce the cost of installing a home battery system.
What Is the Federal Solar Battery Rebate?
The Federal Government’s Cheaper Home Batteries Program begins on 1 July 2025 and provides up to $335 per usable kilowatt-hour of battery storage capacity. This translates to approximately $3,350 off a standard 10kWh battery system.
Federal Battery Rebate Overview:
- Start Date: 1 July 2025
- Value: Around 30% of battery system cost ($335 per usable kWh)
- Eligibility Requirements:
- Battery must be VPP-capable (Virtual Power Plant ready) & mandatory participation in a VPP may apply.
- System must be installed with new or existing rooftop solar
- Installer must be Clean Energy Council accredited
- Applies to: Homes, small businesses, and community facilities
- Not means-tested
- Delivered through: The Small-scale Renewable Energy Scheme (SRES)
How Much Can You Save with Both Rebates?
If approved, combining the WA and Federal solar battery rebates a typical 10kWh battery could be discounted by around $5,000 to $7,500 for eligible households.
Example Combined Savings With a 10kWh Battery:
| Customer Area | WA Rebate | Federal Rebate | Estimated Total Saving |
|---|---|---|---|
| Synergy (Metro WA) | $1,300 | ~$3,700 | ~$5,000 |
| Horizon (Regional WA) | $3,800 | ~$3,700 | ~$7,500 |
Actual amounts may vary depending on system size, installer pricing, and administration costs associated with both program requirements.
Get a Good Quality Battery!
The availability and scale of the federal and WA battery rebates will inevitably attract companies to the market who will be happy to install low quality batteries at practically no cost. You will only be able to claim these rebates once, so we highly recommend you do it right the first time.
To review all the batteries available on the Australia market we recommend you check out our battery reviews written independently by the Solar Choice team and backed by 1,000s of verified reviews from real customers.
Final Thoughts
The WA Home Battery Rebate is a rare opportunity to slash your power bills and future-proof your energy setup — but spaces are limited.
Given the combination of the WA and Federal rebate will pave the way for homeowners to save up to 50% or more of battery costs, we expect a surge of interest from customers and the 100,000 spots to be taken up very quickly.
Be ready, be early, and reap the benefits of secure, affordable home energy storage.
