Australia reached 26.8 GW rooftop solar capacity by June 2025, representing nearly 75% of the 2030 target, says CEC
Rooftop solar produced 12.8% of national electricity in H1 2025, with installations declining slightly on an annual basis
Home battery installations surged 191% in H1 2025, driven by government rebates and schemes
Australia’s rooftop solar installations reached a cumulative 26.8 GW across 4.2 million households and small businesses at the end of June 2025. This represents nearly 75% of the country’s 2030 rooftop solar target of 36 GW, as outlined in the Australian Energy Market Operator’s (AEMO) Integrated System Plan, says the Clean Energy Council (CEC).
It forecasts the market to beat projections by 3.3% to end up exceeding the target with 37.2 GW by June 2030.
According to the CEC’s latest bi-annual Solar and Storage Report (Jan-Jun 2025), rooftop solar accounted for 12.8% of the country’s electricity generation in H1 2025. Australia installed 1.1 GW of new rooftop solar capacity within January and June this year, installing 115,584 systems and contributing 15,463 GWh to the national energy mix. This was, however, 15% lower than 1.3 GW installed in H1 2024 owing to seasonality. In 2024, Australia installed 3 GW of rooftop solar capacity (see Australia Installed 3 GW Rooftop Solar Capacity In 2024).
At 326 MW, Queensland saw the largest capacity addition during the initial half of 2025, followed by 321 MW in New South Wales (NSW), and 230 MW in Victoria. In cumulative terms, NSW was the state with the highest rooftop solar capacity of 7.5 GW, followed by Queensland’s 7.2 GW. Victoria ranks 3rd on the list with 5.4 GW.
Australians are also warming up to battery energy storage systems (BESS) as home battery installations increased by 191% during H1 2025 with the addition of 85,000 units, taking the cumulative installation to 271,000, double from the last 12 months.
Con Hristodoulidis, CEC’s General Manager for Distributed Energy, said, “Australian consumers and small businesses are delivering the transition at breathtaking speed, turning suburban roofs into one of the biggest power stations in the country.”
This adoption is driven by government rebates such as the Federal Cheaper Home Batteries Program and the WA Residential Home Battery Scheme. CEC wants the government to expand these programs to now renters and social housing tenants. “Nearly a third of all Australian households are renters. To make sure everyone benefits, governments can further expand schemes to incentivise landlords and support social housing tenants, so all Australians can lower their bills,” added Hristodoulidis.
