Australia’s love affair with rooftop solar has reached a new zenith, with the nation installing a record-breaking amount of small-scale solar capacity in March 2026. The surge has shattered previous records, signalling a potentially massive year for the residential and commercial solar sector as households and businesses race to capitalise on government incentives before significant changes take effect.
New data released by industry analysts SunWiz reveals an unprecedented 341 megawatts (MW) of small-scale rooftop photovoltaic (PV) systems were registered across Australia in March. This figure represents a nearly 20% jump from February and places the market a remarkable 16% ahead of the same period in 2025. The record month suggests 2026 could become a standout year for the Small-scale Technology Certificates (STC) market.
“Up until now, we have never had to report on PV volumes as high as 341 MW,” said SunWiz Managing Director Warwick Johnston, highlighting the scale of the achievement.
The Battery Boom Pull-Through Effect
One of the primary catalysts for the record solar uptake is the immense success of the federal government’s $7.2 billion Cheaper Home Batteries Program (CHBP). While directly aimed at energy storage, the program has had a powerful knock-on effect on solar panel installations. The program, which has already supported the rollout of approximately 300,000 batteries, is encouraging homeowners to install larger solar systems to ensure they have enough generation to charge their new energy storage units.
According to Johnston, the battery program is effectively “turbocharging battery uptake, [and] it’s pulling larger solar systems along with it, since bigger batteries demand bigger panels.” This trend is pushing both the average solar system size and the total national registered capacity to all-time highs. The synergy between solar and storage is becoming a dominant force in the Australian residential energy market.
A Race Against the Rebate Clock
The other critical factor driving the installation frenzy is a looming deadline. The government has confirmed that the subsidy structure for the Cheaper Home Batteries Program will change on May 1, 2026. The current flat, ‘per kilowatt-hour’ discount will be replaced by a tiered rate system based on battery size.
From May 1, the rebate will be tapered for larger systems: the full incentive applies to the first 14 kWh of capacity, dropping to 60% for the next 14 kWh, and just 15% for capacity between 28 kWh and 50 kWh. This has created a significant rush as consumers and installers scramble to have systems installed and registered to maximise their savings under the current, more generous scheme.
This urgency was reflected in the battery market itself, which also hit a record in March with nearly 1.6 GWh of small-scale storage capacity installed, a 35% increase on the previous month.
Growth Seen Across the Nation
The surge in rooftop solar installations was not confined to one region, with growth recorded across all states and territories. The Northern Territory saw a massive 43% month-on-month increase, while New South Wales recorded a 32% rise. NSW also set a new state-level record for battery installations, registering over 600 MWh in March alone.
This nationwide momentum, driven by a combination of attractive government incentives and a clear policy deadline, has set a new benchmark for the Australian rooftop solar industry. While the pace may adjust after the May 1st changes, the record-breaking first quarter demonstrates that the appetite for solar power and energy independence among Australian households remains stronger than ever.
