Do I need to apply?

Is this a government website?
No. This is an independent guide.
How much money do I lose if I install after January 1, 2027?
Roughly $500 on a typical 13 kWh battery. The rebate steps down from 6.8 to 5.7 STCs per kWh — about 16% lower — so the same system installed in January earns roughly $529 less than one installed in December. The rebate keeps dropping every six months through 2030, so earlier is always cheaper.
Can I install solar and the battery at the same time and still qualify?
Yes. The battery only needs to be paired with solar — it does not have to be an existing system. Many installers quote both together, and the rebate is calculated on the battery only. Use an SAA-accredited installer and a CEC-approved battery so the discount comes straight off your invoice.
Which battery brands are eligible for the rebate?
Any battery on the Clean Energy Council's approved list qualifies, as long as it is 5–100 kWh nominal. Most major brands sold by Australian solar installers are on the list. Your installer should confirm the specific model before you sign — never pay a deposit until you have seen it in writing.
Do off-grid homes qualify for the rebate?
Yes — off-grid systems can qualify if the battery is paired with solar and meets the other rules. However, the on-grid requirement to be VPP-capable does not apply off-grid. Check with your installer, because some state top-ups are restricted to grid-connected homes.
Do I have to join a virtual power plant (VPP)?
No. For on-grid installs the battery must be VPP-capable — able to join one — but joining is optional. You can keep the battery purely for your own use. Some households do join a VPP for extra payments, but it is a separate decision and never required for the rebate.
Can I claim the rebate if I move to a new house?
The rebate is one per premises, not one per person. If the previous owner already claimed a rebate at your address, you cannot claim another one there. When buying a house with a battery already installed, ask whether a rebate was claimed — the seller should know.
Can small businesses claim the battery rebate?
Yes. There is no income test, and the program is open to households, small businesses and community organisations. One rebate applies per premises, and the same size, solar-pairing and installer rules apply. Businesses should also check whether they can combine it with any other incentives.
