Frequently asked questions

Am I eligible for the solar rebate in Australia?
Almost every Australian household installing an eligible solar PV system under 100kW can access the federal Small-scale Technology Certificate (STC) discount, applied at the point of sale by your installer. Some states add their own: Victoria offers a $1,400 Solar Victoria rebate, NSW has Energy Savings Scheme certificates, and South Australia runs the REPS. Enter your postcode above to see exactly which rebates apply where you live.
How much is the federal home battery rebate?
The federal Cheaper Home Batteries Program provides a point-of-sale discount of $244 per usable kWh on a tiered basis from 1 May 2026. A typical 10 kWh battery receives around $2,440. The rebate is capped at 50 kWh of usable capacity.
Can I claim solar and battery rebates at the same time?
Yes. The federal STC solar discount and the federal Cheaper Home Batteries battery discount are separate and stack, and several states add their own top-ups on top. Installing solar and a battery together is the most common way to maximise the combined rebate.
Does my state have its own solar or battery rebate?
It varies. Victoria, NSW, South Australia and the ACT run their own solar and/or battery incentives on top of the federal schemes, while Queensland, WA, Tasmania and the NT currently rely on the federal rebates. The calculator above shows the specific programs available in your state.
How accurate are these estimates?
The figures are suburb-level estimates built from PumpSwap’s cost and rebate data for a 6.6 kW solar system and a 10 kWh battery, using your area’s sun hours, electricity rate and feed-in tariff. Rebate values change with system size and the certificate market, so treat them as a guide. Your installer confirms the exact numbers in a written quote.
