One in three Australian homes now has rooftop solar
About 4 million Australian homes have rooftop solar. In 2026, records are breaking as costs drop and subsidies drive adoption.
Australia's use of rooftop solar is speeding up. About 4 million homes and small businesses have systems installed, about 36% of all households.
The second quarter of 2026 set records in every Australian state. Postcode 3029 in western Melbourne has more solar than anywhere else in Australia.
More than 28,000 systems have been installed there since 2001. Australia now generates more solar electricity per person than any other country in the world.
Three things are driving the boom: sunshine, government certificates that cut upfront costs, and relatively high electricity prices. Australia's housing also helps.
Low-density suburbs with plenty of roof space make installation easier than in many other countries. Rooftop solar now supplies more than 40% of the electricity used during midday hours.
On some days it peaks above 60%.

Why it mattersSolar is reshaping Australia's electricity system. It cuts bills for households. It pushes fossil fuel generators toward decline as battery storage grows.
AustraliaA typical 10kW solar system in Australia produces enough electricity for an average household including an electric car, and rooftop solar will supply about 27% of the country's electricity by 2050 under current projections.
