In Australia, the main solar rebate is usually an upfront discount created through Small-scale Technology Certificates (STCs) for eligible solar PV systems. The value depends on factors such as system size, location and installation date, and is generally arranged by a Clean Energy Council-accredited installer rather than paid directly to you. Some states and territories also offer separate rebates or interest-free loans, with their own eligibility rules and funding limits. Check the Clean Energy Regulator, your state energy department and a licensed installer before choosing a system, as eligibility and the final discount are not guaranteed.
