Homeowners may be eligible for an upfront discount through the federal Small-scale Renewable Energy Scheme, usually arranged by an eligible solar installer for an approved system. Some states and territories also offer separate rebates, loans or battery incentives, with eligibility depending on factors such as location, system size, property status and installation date. The available benefit and final discount are not guaranteed and must be confirmed by the relevant scheme administrator and installer. Check energy.gov.au and your state or territory government website, then compare quotes from an accredited installer.
