Homeowners may benefit from Small-scale Technology Certificates (STCs) when installing an eligible solar PV system under the federal Small-scale Renewable Energy Scheme. In most cases, the accredited installer creates and sells the STCs, passing their estimated value on as an upfront discount rather than the homeowner claiming cash directly. The discount depends on factors including the system’s capacity, location, installation year and the certificates’ market value, so it is not a fixed amount. Ask for the STC calculation in your quote and check eligibility with the installer or the Clean Energy Regulator.
