Solar battery rebates in Australia

As of July 2026, the federal battery rebate is 6.8 small-scale technology certificates (STCs) per usable kilowatt-hour, worth about $250 per kWh at current certificate prices, roughly 30% off an installed battery. That works out to around $2,400 to $2,700 off a 10kWh battery and $3,300 to $3,600 off a 13.5kWh unit, applied straight to your invoice at the point of sale. Most states add a separate incentive on top, which we list state by state below.

For the rest of 2026 the federal rate stays at 6.8 certificates per usable kWh, roughly 30% off, after two cuts already this year (9.3 fell to 8.4 on 1 January 2026, then to 6.8 on 1 May 2026). The next scheduled cut lands on 1 January 2027, so the same battery gets less off if you install after New Year. The step-down schedule has the full timetable in dollars.

Every Australian household can access the federal Cheaper Home Batteries discount, roughly 30% off an eligible battery, straight off your invoice. Most states and territories also run their own separate incentive: NSW and QLD VPP top-ups, Victorian and ACT interest-free loans, WA and SA rebates, and more. We keep the federal discount and any state incentive as two real numbers, never merged into one headline, and tell you exactly what you qualify for.

We keep these two separate rather than merging them into one headline. The federal Cheaper Home Batteries discount takes roughly 30% off a typical battery, around $2,400 to $3,300 off a 10 to 13 kWh unit, straight off your invoice. Most states then add a separate incentive on top, which varies by state and is genuinely worthwhile in WA and SA. The exact figures depend on your postcode, battery size and provider.

The federal discount comes off the price before you pay. Your accredited installer applies it to the invoice. Some state programs are loans or post-install payments. We explain exactly how each one works for your situation.

The program runs to 2030, but the value steps down on a schedule. It has already been cut twice in 2026, most recently to 6.8 certificates per usable kWh on 1 May, and the next cut is set for 1 January 2027. See when the battery rebate ends for the timetable in dollars.
