In Australia, the main solar rebate is usually the federal Small-scale Renewable Energy Scheme, where eligible systems create Small-scale Technology Certificates (STCs) that an approved installer may apply as an upfront discount. The value depends on factors such as your system size, location, installation date and the applicable deeming period, so it is not a guaranteed fixed amount. State or territory battery programs may have separate rules and funding limits. Compare quotes carefully and check current information with the Clean Energy Regulator, energy.gov.au and an accredited solar installer.
