Australia continues to lead the world for solar installations.

Rooftop solar took a hit in 2021 with the industry growing a third less than expected thanks to lockdowns and supply chain disruptions, despite still showing strong growth overall. More than 3m households and small businesses across the country now have solar panel systems installed, with the milestone reached in November. According to registration data provided by solar consultancy company SunWiz, 3.24GW of new solar capacity was added across the country last year, representing 10% growth on the previous year.

These figures include small rooftop systems of less than 100MW registered by homeowners and small businesses, and do not include large, industrial-scale solar installations. Queensland now has the most installed capacity, with 4,483MW, closely followed by New South Wales (4,256MW) and Victoria (3,839MW). Australia continues to lead the world for solar installations with a total installed capacity of just under 17GW.
