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.
Retailer certificate schemes have been growing in popularity in recent years as a policy mechanism to help deliver the energy transition. This report puts forward some recommendations on how to improve the efficiency of these schemes. It also includes a deeper dive into the Victorian Energy Upgrades program and South Australian Retailer Energy Productivity Scheme.
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.
