🔋 FAQSolar & home batteries: your questions, answered
Straight answers to the questions and worries people have before they buy.
How much is the federal battery rebate in 2026?
It works out to around 30% of the installed cost. For batteries installed from 1 May to 31 Dec 2026, each usable kWh creates 6.8 STCs for the first 14 kWh, then less above that. At roughly $39 per STC, a 10 kWh battery gets about $2.6k off. Calculate yours.
Will the rebate drop?
Yes, it steps down every six months. The STC factor falls to 5.7 on 1 Jan 2027 and 5.2 on 1 Jul 2027 (DCCEEW). Battery prices have also been falling, so focus on the total price you pay.
Do I need solar panels to get the discount?
The program is for batteries installed with solar PV, which can be new or existing. Check the eligibility page on DCCEEW for the details.
Do I have to join a virtual power plant (VPP)?
Grid-connected batteries must be VPP-capable to qualify. Joining a VPP is a separate decision.
Will a battery keep my power on in a blackout?
Only if the system is designed and installed with backup capability. Many aren't by default, so ask your installer.
Is a quote comparison site free?
Yes, sites like Solar Choice are free for homeowners. Installers pay them, and we may earn a referral fee if you request quotes through our links.
How long does a battery last?
Warranties commonly cover around 10 years, but terms differ by brand. Compare the warranty's throughput or capacity terms on each quote.
