"Boom far from over," but 2025 goes down in history as the year home batteries went mainstream

A new report released on the first anniversary of the launch of Australia’s Cheaper Home Batteries scheme has confirmed that 2025 was a record smashing year for small-scale storage, with 221,000 residential battery systems installed over the calendar year, adding nearly 5 gigawatt-hours of storage.

This number has since more than doubled – recent updates have put the total number of home battery systems installed through the federal rebate at more than 450,000, and counting, as the scheme ticks over into its second year.

But the Australian Battery Marker Report, published on Wednesday by SunWiz, documents a year where home batteries hit the mainstream and fundamentally changed the course of the consumer energy revolution.

In total, SunWiz says 221,000 systems were installed in 2025, compared with 72,500 the previous year, delivering an additional 4,790 megawatt-hours (MWh) of new storage capacity to the grid.
