Homes in Cairns may be eligible for the federal Small-scale Renewable Energy Scheme (SRES), where eligible systems receive Small-scale Technology Certificates (STCs) that an approved installer generally applies as an upfront discount. The value and eligibility depend on factors such as system size, equipment, installation date and your installer’s requirements. Queensland or local battery incentives may also be available from time to time, but programs can change or close. Check current information at energy.gov.au and the Queensland Government website, then ask an accredited installer to confirm the applicable discount and provide a written quote.
