Australia’s estimated total potential for rooftop solar is 179 gigawatts with an annual energy output of 245 terawatt-hours – exceeding current electricity consumption on the main grids in Australia.

This report explores Australia’s potential for rooftop solar – providing estimates of both the nation’s available roof space, and our solar potential. It concludes that Australia is currently only using five per cent of available roof space and has the potential of 179 gigawatts with an annual energy output of 245 terawatt-hours.

lt should be noted that this study is over 5 years old. lt used a 250 watt solar panel as the basis for the calculation.

The average new solar panel in 2024 is 450 watts. An 80 percent increase on the modelling !!!
