Compare the Market said in a new report that Australia leads in low residential solar costs, with rooftop PV installations more than AUD 2 ($1.25)/W cheaper than the most affordable regions in Canada and the United States.
The lowest residential solar costs among all regions studied, at just AUD 0.80/W, are in South Australia, where rooftop solar is installed on more than 40% of homes, according to the research company.
