The main Australian solar rebate is usually provided through Small-scale Technology Certificates (STCs), which can reduce the upfront price of an eligible solar panel system. The value depends on factors such as the system’s size, location, installation date and the applicable deeming period, and the installer generally handles the paperwork. State and territory programs may offer additional assistance, but eligibility and funding can change. Ask an accredited installer for an itemised quote and check current information on energy.gov.au before signing a contract.
