A solar rebate comparison should look at both federal incentives, such as Small-scale Technology Certificates (STCs), and any current state or territory programs for solar panels or batteries. The value and eligibility can depend on system size, location, installation date, property details and the installer’s accreditation, so an advertised discount may not apply to everyone. Ask installers to show the gross price, estimated rebate or certificate value, and final out-of-pocket cost separately. Check current information on energy.gov.au and your state or territory government website, then confirm the figures with an accredited installer before signing.
