Methodology + sources
Rebate and feed-in figures are verified against canonical government sources (the Clean Energy Regulator and each state energy department). The September quarter 2026 market snapshot uses CER data as reported in the minister's 15 October 2026 release. System and battery prices are compiled from our installer network's quoted prices and public 2026 price guides, expressed as fully-installed retail before rebates. Figures are planning estimates that move quarter to quarter; this report is refreshed monthly.
Common questions
What is the average cost of solar in Australia in 2026?
A typical 6.6 kW solar system costs about $6,900-$9,200 fully installed before rebates, or $4,917-$7,654 after the federal STC rebate depending on the capital city (installed prices from the Solar Choice Price Index, October 2026, checked 10 October 2026). Home batteries average around $1,134 per usable kWh installed.
How much is the solar rebate in Australia in 2026?
The federal STC rebate is worth $1,546-$1,983 on a 6.6 kW system installed in 2026, varying by STC zone (highest in Northern Territory, lowest in Victoria). The federal Cheaper Home Batteries Program adds about $270 per usable kWh for batteries, and several states stack their own rebates on top.
Which Australian state has the most expensive electricity?
Tasmania has the highest average power bill in our dataset (about $2,336 a year). On our solar cost calculator a 6.6 kW system pays back in about 4.3 to 7.6 years on a $450 quarterly bill, on bill savings alone.
