Australia’s energy landscape has transformed dramatically over the past 25 years, driven in part by the Renewable Energy (Electricity) Act 2000 and the introduction of renewable energy certificates in 2001. Through the Small-scale Renewable Energy Scheme, households have been incentivised to install rooftop solar with the help of Small-scale Technology Certificates (STCs). From just 118 rooftop systems in 2001, over four million Australian homes now generate their own power. We take a closer look at regional trends in solar adoption, beginning with the early pioneers and the trajectory of small-scale PV uptake across the country.
