As of June 2025, data from the Clean Energy Regulator (CER) shows rooftop solar capacity has surpassed 26.7 GW, with more than 4.15 million systems now operating nationwide. Building on these figures, we examine the cost of heating a home with gas verses solar in winter, the levelised cost of energy, and the current payback period for residential solar.
Recent figures from the Clean Energy Regulator (CER) reveal in the first nine months of 2024, rooftop solar installations for homes and businesses added 2.03 GW of capacity from 214,813 solar PV systems. In addition to the latest installation statistics, we take a look at other developments with rooftop solar as well as post code data to identify leading suburbs installing systems.
By the end of the first half of this year, solar PV installations had been fitted to more than 3.85 million Australian rooftops with a capacity of 23.65 GW, according to the Clean Energy Regulator. In addition to the latest installation statistics, we take a look at other developments with rooftop solar, as well as utility-scale batteries. Read more.
