Homes in the North had the largest installations of roof systems in the second quarter. It has the highest average installed system size of 14.1 kW between April 1 and June 30, 2023, by Queensland and South Australia respectively, which have installed average The system scale has reached 10.1 kW.

The AEC said the increase in system size continued a trend of recent years, with Australian households and businesses keen to take advantage of technological advances and falling costs in the market, seeking greater energy independence.

As of the end of the second quarter, the total installed rooftop solar capacity in Australia had reached 20.5 GW, with more than 61,000 new systems connected to the grid in three months, with a total installed capacity of 520 MW.
