Australia’s residential energy sector experienced a historic surge in February as homeowners rushed to capitalize on federal subsidies before upcoming policy shifts. Driven by the “Cheaper Home Batteries” program, energy storage registrations hit a record 1.2 GWh, while rooftop solar installations reached their highest February levels to date. This dual growth highlights a robust market transition toward larger integrated systems. Despite a slight decrease in average solar system sizes, the overall momentum suggests a promising outlook for the renewable energy industry throughout 2026.
The Australian energy storage market reached a significant milestone in February, with registrations for small-scale capacity hitting a record 1.2 GWh. This represents a 24% increase compared to January 2026, a spike largely attributed to impending changes to the federal government’s Cheaper Home Batteries rebate program. With the new regulations set to take effect on May 1, consumers have accelerated installations to secure current financial benefits.
According to data from solar research firm SunWiz, the surge was nationwide, with every state reporting growth in battery adoption. Tasmania emerged as the frontrunner, recording a 58% increase in registrations. Market trends indicate a clear preference for larger storage solutions, specifically within the 40 kWh to 50 kWh range. This shift pushed the average battery size to 10.34 kW, continuing a long-term trend of increasing capacity since the introduction of incentives for energy storage.
The rooftop solar sector mirrored this upward trajectory, with 281 MW of new small-scale capacity registered during the month. This figure marks a substantial increase from the 224 MW recorded in January and stands as the highest February total in the country’s history. Year-to-date volumes are currently tracking 6% ahead of the same period last year, signaling a strong recovery after a volatile start to the year.
SunWiz Managing Director Warwick Johnston noted that while the market is showing signs of maturity, demand remains resilient. The Northern Territory saw the most dramatic solar growth at 73%, while New South Wales, Queensland, and Tasmania all posted gains exceeding 30%. Interestingly, while total capacity rose, the average size of individual solar panel systems decreased slightly for the second month in a row, settling at 10.3 kW. This suggests a broader base of participants entering the market even as the industry shifts toward integrated battery and solar module configurations.
