The Cheaper Home Batteries Program is now available to help more people install batteries.
Australian households, businesses and community organisations can get a discount of around 30% on the upfront cost of installing a range of small-scale battery systems (5 kWh to 100 kWh).
The Clean Energy Regulator (CER)(external link) administers the program and the government funds the discount.
STCs can only be claimed for the first 50 kWh of a solar battery’s usable capacity.
Amount of support according to system size
From 1 May 2026 the STC factor will taper according to the amount of capacity installed:
•From 0 kWh up to 14 kWh (inclusive): STC factor applied at 100%
•Every kWh greater than 14 and up to 28 kWh (inclusive): STC factor applied at 60%
•Every kWh greater than 28 and up to 50 kWh (inclusive): STC factor applied at 15%.
STC factors will continue to decrease every six months.
