Australia’s main federal solar incentive is the Small-scale Renewable Energy Scheme, which usually reduces the upfront cost of an eligible solar system through Small-scale Technology Certificates (STCs). The amount depends on factors such as system size, location, installation date and the certificate price, so it is not a fixed rebate paid directly to every household. State and territory programs may offer separate incentives, including battery rebates or loans, with their own eligibility rules and funding limits. Check energy.gov.au and your state or territory government website, and ask an accredited installer to explain the current costs and assumptions.
