Rooftop solar Australia’s second largest generator

The Australian Energy Council (AEC) has released its Quarterly Solar Report, revealing that rooftop solar is now the second largest generator by capacity in Australia – contributing over 14.7GW in capacity. 

The AEC’s Quarterly Solar Report shows while coal-fired generation has more capacity, rooftop solar is continuing to expand with 109,000 systems installed in the second quarter of 2021. 

AEC Chief Executive, Sarah McNamara, said, “While the 2020/21 financial year was difficult for most industries due to the impact of COVID-19, Australia’s rooftop solar PV industry does not appear to have been overly affected, based on this AEC analysis.”

Solar uptake by state

  • New South Wales cracked the nation’s top five with two postcodes during the 2021 financial year, with the biggest growth for NSW solar installations landing north west of the Sydney CBD
  • Victorian postcodes 3029 (Hoppers Crossing, Tarneit, Truganina) and 3064 (Donnybrook) have held the top ranks for the past two years; these suburbs had an equivalent number of solar systems installed with capacities of approximately 18.9MW
  • Queensland claimed four spots during 2020 but southwest Brisbane’s 4300 is the only postcode in the top ten in 2021, ranking third with nearly 2,400 systems installed and 18.1MW connected to the grid
  • Western Australia has three postcodes in the top ten, each installed around 1800 systems with a capacity of 12MW in FY21

“All jurisdictions, except the Northern Territory, hit records for the number of solar panels installed compared to the previous financial year,” Ms McNamara said. 

“During the 2020/21 financial year, around 373,000 solar systems were installed on Australian homes, up from 323,500 during 2019/20. Installed capacity also jumped from 2,500MW to more than 3,000MW.”

Ms McNamara said that continued low technology costs, increased working from home arrangements and a shift in household spending to home improvements during the COVID-19 pandemic played a key role in the increase of rooftop solar PV systems.
