For most Australian homes, the main solar rebate is the federal Small-scale Renewable Energy Scheme, which provides Small-scale Technology Certificates (STCs) for eligible systems. An installer usually applies the STC discount to the price, but the value depends on factors such as your location, system size, certificate prices and current rules. Some states and territories also offer separate battery or solar incentives, with eligibility decided by the relevant government or provider.
