Warwick Johnston, SunWiz’s Managing Director, explained the reasons behind the reduced activity: “This year, Easter, school holidays, and ANZAC Day all fell in April, contributing to an anticipated downturn in volumes. The federal election has also weighed on activity in recent months.” These overlapping events, combined with the election, disrupted the usual pace of installations.
The April figures show a 6% drop in year-to-date installations compared to the same period in 2024. However, Johnston noted that the current numbers remain higher than those recorded in 2022 and 2023, suggesting the market retains some resilience despite the recent decline.
The downturn affected nearly all Australian states and territories in April 2025, with Queensland being the exception, where installation volumes held steady after a dip in March. The Australian Capital Territory experienced the largest decline at 19%, while Victoria saw the smallest reduction at 9%. This variation reflects regional differences in market dynamics and external factors.
All capacity segments saw reduced installations in April. The 50-75 kW range experienced the smallest decline, dropping by 5%, while the 30-50 kW segment faced a steeper reduction of 18%. Despite the overall downturn, the 15-100 kW commercial segment continued to perform strongly, with volumes surpassing those of the previous three years. This highlights sustained demand for commercial-scale rooftop solar systems.
The data underscores the impact of seasonal and external factors on Australia’s rooftop solar market. While April’s decline reflects temporary disruptions, the sector’s performance remains robust compared to earlier years, particularly in the commercial segment. As the holiday period and election-related pressures subside, the market may see renewed momentum in the coming months.
