Australia\u2019s rooftop solar<\/a> fleet has continued its strong growth, reaching a total of 28.3 GW of installed capacity by the end of 2025, spread across around 4.3 million systems nationwide. New figures from the Clean Energy Council\u2019s (CEC<\/a>) latest Rooftop Solar and Storage Report<\/em> show households and businesses added 2.6 GW of new small-scale solar during 2025, including 1.5 GW in the final six months of the year.<\/p>\n\n\n\n

The CEC reports that 139,080 rooftop solar systems were installed between July and December 2025, bringing the year\u2019s total to 254,664 units.<\/p>\n\n\n\n

Rooftop PV\u2019s share of electricity generation also continued its upward trend, accounting for 14.2% of total supply in the second half of the year, up from 13.4% over the same period in 2024.<\/p>\n\n\n\n

CEC Chief Executive Jackie Trad described the scale of Australia\u2019s rooftop solar build-out as a \u201cnational triumph\u201d, noting that aggregated small-scale solar capacity has now overtaken the output of the entire coal-fired fleet, which stands at 22.5 GW.<\/p>\n\n\n\n

\u201cOur biggest power station now sits on the rooftops of more than 4.3 million homes,\u201d Trad said. \u201cIt not only leads Australia\u2019s transition to renewables but is also unmatched globally on a per-capita basis.\u201d<\/p>\n\n\n\n

While total capacity continued to rise, installation numbers dipped 15% compared with 2024, when just over 300,000 systems were added. The CEC says the slowdown indicates the market is approaching saturation and households are increasingly turning their attention to energy storage.<\/p>\n\n\n\n

\u201cThis is the first year since 2020 that rooftop PV installations have not exceeded 300,000,\u201d the report notes. \u201cIt suggests we have passed the peak for new rooftop solar systems as consumer demand shifts towards small-scale batteries.\u201d<\/p>\n\n\n\n

Trad said a suite of government incentives \u2013 including the federal government\u2019s $7.3 billion Cheaper Home Batteries<\/em> program, introduced on 1 July \u2013 has dramatically accelerated household storage uptake.<\/p>\n\n\n\n

\u201cBattery uptake has been extraordinary, with installations more than doubling in just one year,\u201d she said. \u201cAustralians installed as many home batteries <\/a>in the final six months of last year as they did in the preceding five years combined.\u201d<\/p>\n\n\n\n

A record 183,245 batteries were added in the second half of 2025, a four-fold jump on the same period in 2024. That six-month figure alone is equal to 99% of all battery sales recorded between 2020 and 2024, lifting the total number of household battery systems to 454,753 by year\u2019s end.<\/p>\n\n\n\n

The CEC said the rapid expansion of the small-scale market has outpaced expectations, with rooftop solar capacity now on track to exceed the Australian Energy Market Operator\u2019s (AEMO) 2030 projections by around 1 GW. AEMO\u2019s 2024 Integrated System Plan<\/em> forecasts distributed solar to reach 36.1 GW in the National Electricity Market by 2029\u201330.<\/p>\n\n\n\n

Meeting that forecast would require an annual average of 2.5 GW of new rooftop PV from 2023\u201324 onwards. Over the past five years, the NEM has averaged 2.7 GW each year.<\/p>\n","protected":false},"excerpt":{"rendered":"
