Rooftop solar delivered 12.8% of Australia’s electricity in first half of 2025, according to a new report from the Clean Energy Council.
Australia’s rooftops continue to be a clean-energy powerhouse, with Australia on track to meet—and likely exceed—its 2030 rooftop solar targets.

The bi-annual Rooftop Solar and Storage Report reveals that by June this year, Australians had installed a total of 26.8GW of rooftop solar capacity across 4.2 million homes and small businesses.
The Australian Energy Market Operator’s (AEMO) Integrated System Plan, which underpins the national 82% renewable energy target, expects that by 2030 Australia will have approximately 36GW of rooftop solar installed throughout the National Electricity Market.
The amount of rooftop electricity currently installed represents nearly three-quarters of the capacity needed to meet the 2030 target of 36GW. Based on current trends, the Clean Energy Council expects Australia to have installed 37.2GW of rooftop solar by June 2030, beating projections by 3.3% (Figure 1).
In the first half of 2025 alone, the report found 115,584 rooftop systems were installed nationwide, adding 1.1GW of capacity, with rooftop solar contributing 15,463GWh to the national energy mix.
Queensland added the most rooftop solar in the first half of 2025, with 326MW of installed capacity, followed by New South Wales (321MW) and Victoria (230MW). Overall New South Wales retains the highest overall rooftop solar capacity in the nation at 7.5GW, with Queensland close behind at 7.2GW—leading the nation with more than 1.1 million total installations—while Victoria ranks third with 5.4GW.

Australians are also embracing home batteries at record pace, with 85,000 battery units sold in the first half of 2025— a 191% increase on the same period last year. Cumulatively, 271,000 home batteries have now been installed nationwide, nearly double the total from 12 months ago. Installing rooftop solar can save households up to $1500 per year on energy bills, this almost doubles if you add a battery, with further savings available by joining a virtual power plant.
Government rebates such as the Federal Cheaper Home Batteries Program and the WA Residential Home Battery Scheme, have helped spur demand ahead of their July 1 start dates. The Clean Energy Council is encouraging governments to expand these programs to renters and social housing tenants.
