On 13 July 2026 we re-verified every rebate figure, feed-in tariff and program status on this site against canonical sources: the Clean Energy Regulator, DCCEEW and each state's energy department. Here is what stands as of today.
Federal battery discount: 6.8 confirmed to 31 December 2026
The Cheaper Home Batteries Program factor of 6.8 STCs per usable kWh is confirmed for installs certified through 31 December 2026. It steps down to 5.7 on 1 January 2027, which is worth about $599 on a 13.5 kWh battery (91 STCs vs 76 STCs at the current spot price). If a battery is on your list, installing before New Year locks in the higher rate.
Solar deeming: 5 years for 2026 installs
The STC deeming period for rooftop solar is 5 years for systems installed during 2026, stepping down to 4 years on 1 January 2027. On a 6.6 kW system in Melbourne (zone 4), waiting past New Year costs about $319 in rebate value.
