Data from SunWiz indicates Australia’s rooftop solar market achieved a record level of activity last month. The country registered 341 megawatts of small-scale photovoltaic capacity in March, representing a surge of approximately 19% from the previous month. The current market volume is also reported to be 16% higher than it was at the same point last year.
Analysts link the growth to strong momentum in the market for Small-scale Technology Certificates. A federal program providing rebates for home battery systems is also cited as a contributing factor. This initiative has supported the installation of roughly 300,000 battery units since it began.
The increase in solar installations was observed nationwide. The Northern Territory saw a 43% rise compared to February, while New South Wales experienced a 32% increase. Most system size categories grew, particularly those up to 50 kilowatts, though a slight decline was noted for systems between 75 and 100 kilowatts.
Battery installations also reached a new high, with nearly 1.6 gigawatt-hours of small-scale storage capacity registered in March, a 35% monthly increase. This surge is attributed to consumers accelerating installations ahead of modifications to the federal rebate program scheduled for the start of May. Under the revised scheme, the incentive will shift from a flat rate to a tiered structure based on battery size, while maintaining an average discount of around 30%.
The average battery size set a new record of 40 kilowatt-hours last month, with most systems falling in the 40 to 50 kilowatt-hour range. New South Wales alone recorded over 600 megawatt-hours of battery installations, a 44% monthly increase and a new state record.
