The Clean Energy Council has released its bi-annual Rooftop solar and storage report, providing insight into the current trends and momentum around the adoption and acceleration of solar resources and technology in the sector.
The report shows that Australian consumers and small businesses continue to take advantage of Australia’s abundant solar resources with rooftop solar accounting for 12.8 per cent of all electricity generated in the first half of the year.
In the first half of 2025, there were 115,584 rooftop solar installations on Australian homes and businesses. These installations alone represent more than 1.1 GW (gigawatts) of new installed capacity into the grid.
Queensland emerged as the leading state for total capacity installed, with 326 MW (megawatts), surpassing New South Wales for the first time as the leading state.
When it comes to battery technology, a record breaking 85,000 units were sold in the first half of 2025, with the Federal and Western Australian residential home battery programs spurring an increase in sales in the second quarter of this year.
By the end of June this year, around 5157 approved rooftop solar, inverter products and household batteries were made available to installers across the country.
Ultimately, findings from the report outline the continued effectiveness and assistance of rooftop solar in contributing to Australia’s national target, of 82 per cent of electricity coming from clean energy sources by 2030.
