Record-Breaking Month for Solar and Storage as Subsidy Deadline Looms
Australia’s rooftop solar and home battery market has surged to an all-time high, with new data revealing a massive rush by homeowners to install systems ahead of significant changes to a key federal government subsidy.
According to the latest analysis from industry consultants SunWiz, a record 341 MW of small-scale rooftop solar was registered in March 2026, a 19% jump from the previous month. Even more dramatically, home battery installations soared by 35% to a record 1.6 GWh for the month, as consumers scrambled to maximise their savings.
The unprecedented uptake is being directly attributed to the federal government’s $7.2 billion Cheaper Home Batteries Program (CHBP) and a fast-approaching policy change. From 1 May 2026, the rebate structure for new battery installations will be altered, prompting what SunWiz Managing Director Warwick Johnston described as a market “frenzy.”
“The race to beat the 1 May CBHP subsidy cut sent the market into a frenzy. Installers and homeowners alike scrambled to lock in maximum value,” Mr Johnston said.
Understanding the Policy Shift
The current Cheaper Home Batteries Program offers a straightforward discount for eligible systems. However, from May 1, this will shift to a tiered rate system based on the battery’s size. While the federal government has stated the new structure is designed to maintain an average discount of around 30% for small, medium, and large batteries, the impending change has clearly motivated homeowners to act now to avoid any uncertainty.
The CHBP has been a powerful driver of the home energy storage market. In the nine months since its launch, the program has supported the installation of 300,000 batteries, fundamentally changing the landscape of household energy management.
Mr Johnston noted the powerful link between the battery subsidy and solar system sales. “By turbocharging battery uptake, it’s pulling larger solar systems along with it, since bigger batteries demand bigger panels, sending average system sizes and total registered capacity to all-time highs,” he explained.
A Strong Start for 2026 Renewables
The March installation figures put Australia’s small-scale solar market 16% ahead of the same time in 2025, suggesting 2026 is on track to be a landmark year for the sector. The growth was spread across the country and seen in almost all system size segments up to 75 kW.
This boom in household-level generation and storage is critical to achieving Australia’s broader energy goals, including the target of 82% renewable electricity by 2030. As large coal-fired power stations continue to retire, the distributed energy resources (DER) in homes—like solar panels and batteries—play an increasingly vital role in maintaining grid stability and providing clean power.
The record-breaking data from March underscores the significant impact that federal policy incentives can have on consumer behaviour and the acceleration of Australia’s clean energy transition. With the subsidy changes now just weeks away, the industry will be closely watching to see how installation rates evolve in the second half of the year.
