Home battery rebate explained for Australian households
Home battery rebate rules took effect on 1 July 2025, and the support is a discount on the price, not a cheque. The Cheaper Home Batteries Program is meant to cut around 30% off the upfront cost of a small solar battery for households and small businesses. Your installer usually takes the discount off the quote, so you pay less on the day. Read on for the mechanics, then the points to confirm with your installer before signing.

How the home battery rebate works
The discount runs through the Small-scale Renewable Energy Scheme, which already supports rooftop solar. Each battery earns small-scale technology certificates, or STCs. The seller or an agent trades those certificates, and the saving is passed on to you.
The Australian Government pays for the discount by buying the STCs. The Clean Energy Regulator says this means no extra cost passes to households through their energy retailer. The Regulator administers the program.
Who can claim
You need a solar battery installed with a new or existing rooftop solar system. A single battery with a total capacity of 5 kWh to 100 kWh is eligible. Households and small businesses can claim.
Timing matters. A battery counts as installed when the electrical compliance certificate is signed. If a battery was tested and certified before 1 July 2025, it does not qualify for STCs.
Grid-connected batteries must be able to work with a virtual power plant. You do not have to join one. Off-grid batteries can qualify too, but only if the home is at least one kilometre from a mains power line, or if connecting to the grid would cost more than $30,000.
How big is the discount
The size depends on the battery's usable capacity, not its sticker size. STCs can be claimed only on the first 50 kWh of usable capacity. The discount shrinks a little each year until the end of the decade.
The Department's guide estimated about $372 for each kWh of usable capacity for a battery installed in 2025. That figure assumes $40 per STC and is before any fees charged by the agent who handles the certificates. So a battery with 10 kWh of usable capacity would earn roughly $3,720 before fees. That is an estimate, and the real STC price can move.
The same guide had the value falling by roughly $36 to $40 per kWh every year after that. Waiting a year can cost you money.
Safety and installer rules
The Regulator says the battery must be on the Clean Energy Council approved product list. An installer with battery accreditation from Solar Accreditation Australia must fit it. The job must also meet state and territory electrical safety rules.
The Regulator said it would begin inspecting installed batteries in early July 2025. Ask your installer for their accreditation details and check the battery model against the approved list yourself.
What to check on a quote
- The discount shown as its own line, with the STC value and any agent fee stated.
- The battery's usable capacity in kWh, not only the total size.
- That the battery is on the Clean Energy Council approved list.
- That the installer holds battery accreditation.
- The expected savings and payback period. Under the draft rules, customers are to be given these.
- The installation and certificate dates, so the battery is not signed off before 1 July 2025.
The Regulator also suggests getting several quotes, reading the contract carefully and keeping all emails and quotes from the sales process.
What this means for buyers
The discount can lower the price a lot, but the saving on your power bill still depends on how much solar you make and how you use power. A cheaper battery is only a good buy if it suits your home.
