Search for local solar installers who are accredited to install eligible systems and ask whether they handle the Small-scale Technology Certificate (STC) paperwork. The STC benefit is usually applied as an upfront discount, but the value and your system’s eligibility depend on factors such as location, system size and installation date. Compare written quotes that show the estimated STC value, equipment, warranties and total price, and check the installer’s credentials and reviews. You can confirm current scheme information through the Clean Energy Regulator or energy.gov.au before signing.
