There is no single national price after the solar rebate: the federal Small-scale Technology Certificate (STC) incentive is usually applied as an upfront discount, and its value varies with system size, location, installation date, deeming period and certificate market conditions. Your remaining cost also depends on the panels, inverter, mounting, installation and any switchboard or roof work required. State and territory battery or solar programs may have separate eligibility rules and funding limits. Ask an accredited installer for an itemised quote and check current information at energy.gov.au before comparing offers.
