South Australia homeowners can claim up to $4,950 in stacked 2026 rebates for an eligible solar and battery install. That combines the federal STC rebate (STC Zone 3, worth roughly $3,000 to $4,500 on a typical system), the federal Cheaper Home Batteries rebate (up to about $3,700), with no state scheme, since South Australia is federal-only in 2026. Solar-only installs receive a smaller amount. The 30-second check returns your exact number.
South Australia's Home Battery Scheme closed in 2022 and was not replaced. Federal rebates apply, and SA's high power prices make self-consumed solar pay back fast.
A battery pays off in South Australia when your feed-in tariff is low and you use a lot of power after dark. The federal Cheaper Home Batteries rebate takes up to about $3,700 off the install, which has pulled payback down to roughly 6 to 9 years for most homes. The check estimates your payback from your bill and postcode.
The federal rebates shrink on a set schedule. The STC solar rebate drops a little each January, and the Cheaper Home Batteries rebate fell on 1 May 2026 and now steps down every six months, with the next cut on 1 January 2027. Waiting means a smaller rebate, so today's number is the best it will be.
