In 2026, eligible home solar systems may receive an upfront discount through the federal Small-scale Technology Certificate (STC) scheme, usually arranged by an accredited installer. The value depends on factors such as system size, location, installation date and the market value of certificates, so it is not a guaranteed rebate amount. Some states and territories may also offer separate solar or battery incentives, with eligibility and funding rules set by the relevant government. Check energy.gov.au and your state or territory website, and ask an accredited installer to explain which incentives may apply to your circumstances.
