New figures from the Clean Energy Council (CEC) show that 300,375 Australian homes and businesses installed rooftop pv system units in 2024, delivering almost 3 GW worth of PV capacity. This includes 159,011 rooftop PV systems with a combined capacity of 1.6 GW that were installed during the last six months of the year, together with battery energy storage system (bess).
The CEC said it is the fifth consecutive year that installation figures have surpassed 300,000 units with more than four million rooftop PV systems and a cumulative total capacity of 25.5 GW of rooftop solar now in place across the country.
The CEC's biannual Rooftop Solar and Storage Report shows rooftop PV contributed 30,178 GWh, or 12.4%, of Australia's total energy generation for 2024, up from 11.2% in 2023, and almost doubled from 6.5% in 2020.
While the year delivered significant milestones for rooftop solar, the annual installation rate was 10% lower than the previous year when 333,926 units were rolled out while the total installed capacity of almost 3 GW was 7% down on the 3.2 GW installed in 2023.
New South Wales led the way with the highest installed capacity of any state in 2024, at 952 MW. Queensland (800 MW) and Victoria (582 MW) came in second and third place respectively.
The report shows household battery installations increased in 2024 with 74,582 units deployed, up from 46,127 in 2023. The annual total included 45,233 home battery units sold in the second half of last year, up 55% on the same period the year prior.
New South Wales led the way with the most home battery sales in 2024 with 14,686 installations for the year, followed by Victoria (10,996) and Queensland (8,555).
