The Australian Energy Council’s latest Solar Report updates on developments in the second quarter. Based on current Clean Energy Regulator (CER) data it shows a drop in solar rooftop installations – due to a range of factors including supply chain costs and weather events. Regardless of the drop in Q2, solar continues to play a growing role in the grid. The report looks at factors behind the changes as well as state-by-state shifts.
In the first quarter of 2025, rooftop solar capacity for homes and businesses in Australia surpassed 26 GW, with over 4.1 million photovoltaic systems now in operation, according to the Clean Energy Regulator (CER). Alongside these latest figures, we examine solar adoption rates 25 years after the Renewable Energy (Electricity) Act 2000 established the market for renewable energy certificates (RECs). We also take a closer look at the levelised cost of energy and the current payback period for residential solar systems.
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 quarter this year solar PV installations had put been fitted to more than 3.7 million Australian rooftops with a capacity of 22.58GW, 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 the impact utility-scale solar is having on price setting in the National Electricity Market.
