Adelaide households may be eligible for the federal Small-scale Renewable Energy Scheme, commonly applied as an upfront discount through Small-scale Technology Certificates (STCs) when an eligible solar system is installed. The value depends on factors including the system size, installation date, location and certificate market conditions, so it is not a guaranteed fixed rebate. South Australian battery incentives and other programs can change or close, with eligibility decided by the relevant government department or provider. Check current information on energy.gov.au and the South Australian Government website, then ask an accredited installer to show any assumed discounts separately on your quote.
