In 2026, there is no single Australia-wide cash rebate for solar panels. Eligible small-scale solar systems may receive an upfront discount through Small-scale Technology Certificates (STCs), with the value depending on factors such as system size, location, installation date and the certificate market price. State and territory programs, including battery incentives, can have separate eligibility rules and funding limits. Check the latest information on the Clean Energy Regulator and energy.gov.au, and ask an accredited installer to explain the estimated discount for your circumstances.
