In Australia, the main solar rebate is usually an upfront discount created through Small-scale Technology Certificates (STCs) for eligible systems, rather than a direct cash payment. The value depends on factors such as your system size, location, installation date and the applicable deeming period, and eligibility must meet Clean Energy Regulator requirements. Some states and territories also offer separate solar or battery incentives, with their own rules and application processes. Ask an accredited installer to explain the discount in your quote, and check current information with the Clean Energy Regulator or energy.gov.au.
