 Even with Australia newly emerged as being amongst the world leaders in solar uptake, the study found that as of June 2019 Australia was using less than 5% of the potential capacity for rooftop solar.The study found that the combined annual output from rooftop solar could theoretically reach 245 TWh, more than the current annual grid consumption of just under 200 TWh per year.The Solar Homes and Communities Plan was a rebate provided by the Australian Government of up to A$8,000 for installing solar panels on homes and community use buildings (other than schools).
