Figures are indicative, based on an STC spot price of AUD $38.00 (as at 24 April 2026), deeming factors published by the Clean Energy Regulator (8.4 to 30 April; 6.8 from 1 May), and the 14 kWh un-tapered band announced in the 1 May 2026 program changes. Installer admin fees (typically 2–5% of STC gross) reduce the pass-through to your quote. For batteries larger than 14 kWh, the taper on capacity above 14 kWh is still being finalised by CER — figures in that row will be updated when bands are published. See methodology.
State-level incentives in SA
The Home Battery Scheme (which from 2018 onward subsidised tens of thousands of South Australian battery installs) was wound down in 2024. South Australian households currently rely on the federal CHBP only.
