Deploying solar photovoltaic through subsidies: An Australian case

Australia has garnered significant recognition for its leadership in residential solar energy adoption, driven by incentive programs like the Feed-in Tariff and the Small-Scale Renewable Energy Scheme. Yet limited research has evaluated the policy's effects on residential solar photovoltaics in Australia. We thus examine how Feed-in tariff policies and different policy packages affect residential solar PV adoption using the quarterly data from July 2009 to June 2022. The benchmark results uncover that high Feed-in tariff rates, long-term contracts, and gross Feed-in tariff schemes substantially drive solar adoption in Australia. Still, the observed adverse relationship between cost and installed capacity highlights that upfront Small-Scale Renewable Energy Scheme subsidies effectively promote solar power. Our estimates may provide valuable implications for accelerating solar photovoltaic adoption and achieving renewable energy transitions in Australia.
