Australia’s Solar Battery Rebates by State and Federal + Calculator
Last Update: 12 June 2025
Solar energy has become an essential part of the Australian energy landscape, and many homeowners are looking into solar battery storage to maximise their energy savings and independence. Adding a solar battery to your system allows you to store excess solar energy, use it at night, and protect your home from rising energy costs. Various solar battery rebates and incentives are available across Australia to support this shift.
In this guide, we’ll cover all you need to know about solar battery rebates and incentives in each Australian state, helping you understand the financial benefits and options available to reduce the cost of your solar battery system.
Federal Battery Rebates
The Australian Government supports renewable energy adoption through the Small-scale Renewable Energy Scheme (SRES). Under this scheme, installing eligible solar panel systems can earn Small-scale Technology Certificates (STCs), which can be sold to reduce installation costs. While STCs primarily apply to solar panels, they indirectly lower the overall expense when combined with battery storage.
Cheaper Home Batteries Program (starting 1 July 2025)
the Australian government has announced a massive $2.3 billion incentive (rebate) to make home battery storage more affordable. The newly announced program aims to cut the cost of installing a typical home battery by around 30%, which could mean savings of up to $4,000 (typical 11.5 kWh battery) for many Aussie households. In 2025, the maximum available subsidy is approximately $372 per usable kWh of battery storage. This amount will gradually decrease each year until the scheme ends in 2030. The structure is similar to the Small-scale Renewable Energy Scheme (SRES) currently used for solar systems.
The federal rebate can be combined with existing state and territory battery incentives in WA. The rebate is available to homeowners, small businesses, and community facilities.
Under the new Federal Battery Rebate, businesses installing batteries between 5kWh and 50kWh may be eligible for rebates of up to $18,500. The program would be delivered through the Small-scale Renewable Energy Scheme (SRES), which already provides rooftop solar subsidies.
Batteries installed before July 1, 2025, can still qualify for the rebate — as long as they are not switched on until the program officially begins.
How Much Can You Save with the Federal Battery Rebate?
The new federal battery rebate can significantly reduce your upfront costs. Here's a quick estimate of how much you could save based on the battery size you choose:
| Battery Size (Usable kWh) | Estimated Rebate ($372/kWh)* |
|---|---|
| 5 kWh | $1,860* |
| 10 kWh | $3,720* |
| 13.5 kWh | $5,022* |
| 20 kWh | $7,440* |
| 30 kWh | $11,160* |
| 40 kWh | $14,880* |
| 50 kWh | $18,600* |
* Note: These numbers are estimates. Final rebate amounts may vary slightly due to administrative fees or market fluctuations.
Key Eligibility Criteria for Battery Rebate
To qualify for the 2025 Federal Battery Rebate, your battery system must meet the following requirements and rules:
-
1. Battery Size: Between 5 kWh and 50 kWh
Only battery systems with a usable capacity between 5 and 50 kWh are eligible. You can install a larger system, but the rebate only applies to the first 50 kWh.
-
2. CEC-Approved Battery and Inverter
Both yourbattery system and inverter must be listed on the Clean Energy Council (CEC) approved product list, ensuring they meet national safety and quality standards.
-
3. Virtual Power Plant (VPP) Ready
The battery must be capable of connecting to a Virtual Power Plant (VPP). You don’t need to join a VPP, but your system must be technically ready.
-
4. Paired with Solar
The battery must be paired with a rooftop solar system — either existing or new. Standalone batteries are not eligible.
-
5. Installed by Accredited Professionals
Installation must be done by a professional accredited by Solar Accreditation Australia (SAA) for battery work.
-
6. Switched On After 1 July 2025
The battery must be commissioned on or after 1 July 2025, even if installed earlier.
-
7. On-Grid or Off-Grid Systems Allowed
Both on-grid and off-grid systems may qualify, as long as all other requirements are met.

Western Australia (WA) Battery Rebates
WA Battery Rebate Overview (Starting July 2025)
Western Australia is launching a substantial Residential Battery Scheme starting on or before 1 July 2025, offering up to 100,000 rebates to support households in adopting battery storage systems. Under this program:
From 1 July 2025, WA households will be eligible for a new home battery rebate under the WA Residential Battery Scheme. The rebate applies to batteries with up to 10 kWh usable capacity and can be combined with the Federal rebate for even greater savings. The total rebate amount depends on your electricity provider — either Synergy or Horizon Power.
To be eligible, batteries must be installed by an SAA-accredited installer, listed on the Clean Energy Council approved product list, and be VPP-capable.
State-based rebates will be up to $1,300 for Synergy customers ($130 per kWh of battery capacity) and up to $3,800 for Horizon Power customers ($380 per kWh of battery capacity). In the first year, and with the assistance under the Federal Cheaper Home Batteries program, residents will be able to receive up to $5,000 and $7,500 respectively towards the cost of a 10kWh battery installation. Also households will be required to participate in a Virtual Power Plant (VPP) to be eligible for the Scheme.
The WA portion of the rebate is capped at 10 kWh, but the Federal rebate continues to scale with battery size.
Combined Rebate Amounts (2025 Rates)| Battery Size | WA Rebate (Synergy) | WA Rebate (Horizon) | Federal Rebate | Total (Synergy) | Total (Horizon) |
|---|---|---|---|---|---|
| 5 kWh | $650 | $1,900 | $1,860 | $2,510 | $3,760 |
| 10 kWh | $1,300 (max) | $3,800 (max) | $3,720 | $5,020 | $7,520 |
| 16 kWh | $1,300 (max) | $3,800 (max) | $5,952 | $7,252 | $9,752 |
