Rooftop solar in Australia provides the cheapest, cleanest and most reliable domestic energy in history.

The dynamics that dictate how the price of electricity is set in Australia have been transformed in the last year, not by policy, but by the unusual characteristics of batteries. Unlike any generator before it, batteries are capable of playing both sides of the price-setting equation: supply and demand. Newly compiled data reveals the extent to which the National Electricity Market’s price-setting agenda has been utterly reconfigured.

Australia’s residential solar market continues to expand at pace, supported by high household adoption and growing integration of battery storage systems. The latest data shows approximately 217,000 new rooftop solar systems have been installed over the past 12 months with an estimated 42% of Australian homes now fitted with solar. The country maintains its position as the No.1 globally ranked market for rooftop solar adoption, with an average residential system size of 6.6 kW.

As energy security continues to dominate headlines, Australia is quietly setting records for renewable energy generation.

Australia is in the grip of a record-breaking battery rush. Last week Energy Minister Chris Bowen announced that more than 380,000 home batteries have been installed since July last year. That’s over 100,000 more than the total installed between 2020 and mid-2025. The reason for the rush: government subsidies, which cut the upfront cost by about 30%.
