Adelaide households may be eligible for the federal Small-scale Renewable Energy Scheme, which can reduce the upfront price of an eligible solar panel system through tradable certificates. The potential discount depends on factors such as your postcode, system size, installation date and the accredited installer you use, so it is not a fixed rebate amount. South Australian or federal battery incentives may also be available at times, with separate eligibility rules and funding limits. Check current details on energy.gov.au and confirm the quote and certificate arrangements with an accredited solar installer.
