Small-scale rooftop solar installations in Australia set record in 2020

Australia’s rooftop solar market has defied a challenging 2020 to set a number of new installation records, with the market overcoming disruptions to grow by a massive 39 per cent year-on-year, new analysis from consultancy SunWiz has detailed.

In its latest annual assessment of the rooftop solar market, SunWiz found that the industry had overcome disruptions caused by the Covid-19 pandemic, and some tricky government policy settings, to record almost 3,000MW of new installations throughout 2020, with installation rates increasing as the year progressed.

According to data collected on system registrations, 2020 ended the year with its strongest ever rate of new rooftop solar installations, with virtually every Australian state and territory recording the highest level of new small-scale solar installations in the month of December.

Registration data was collected for systems with a capacity of up to 100kW based on the registration of Small-scale Technology Certificates (STCs), with SunWiz noting that when medium scale commercial systems were taken into account, which are eligible for Large-scale Generation Certificates (LGCs), the rooftop solar market would have well exceeded the 3,000MW milestone in 2020.

“The year ended on a massive high, with a record-smashing 324 MW registered in December. Over 100MW of this was in NSW, and every major state contributed a record monthly tally,” SunWiz managing director Warwick Johnston told Renew Economy. “The capacity registered in the sub-100kW STC market fell a whisker short of 3GW, at 2.97GW. However, when you add in the commercial LGC rooftop market, well over 3GW of rooftop capacity was installed in 2020.”
