This report monitors the progress of the deployment of rooftop solar and behind-the-meter energy storage systems in Australia for the six month period of July to December 2024. The results reinforce the importance of establishing a national home battery rebate scheme, to ease the upfront costs associated with adopting home batteries.

Key findings

• Australia passed four million cumulative rooftop photovoltaic (PV) installations in November 2024.
• Simultaneously, Australia passed 25 GW worth of total rooftop PV capacity. By comparison, black and brown coal combined for a total of 21.3 GW of installed capacity in the financial year 2023–24.
• Rooftop PV contributed 12%, or 30,178 GWh, of Australia’s total energy generation for 2024.
• There were over 45,000 battery units sold in the second half of 2024.
• One in three rooftop solar owners have a battery storage system installed, despite its capability to save households up to 80% for a combined solar battery system.
• There are currently 4,829 approved rooftop solar, inverter and storage products across Australia.
• Among Australian states, the report found New South Wales led the way with the most home battery sales, followed closely by Victoria and Queensland.
