A solar rebate guide should explain the federal Small-scale Renewable Energy Scheme, where eligible systems may receive Small-scale Technology Certificates (STCs) that reduce the upfront price. The value depends on factors such as system size, location, installation date and the market value of certificates, so it is not a guaranteed cash payment. State and territory battery or feed-in support can have separate rules and may change over time. Check current information on energy.gov.au and ask an accredited installer to show how any incentives are reflected in your quote.
