What is a Small-scale Technology Certificate?

Every eligible solar, battery, solar hot water or heat pump system installed in Australia earns Small-scale Technology Certificates (STCs) — tradeable certificates created under the federal government's Small-scale Renewable Energy Scheme (SRES).

One STC broadly represents one megawatt-hour of renewable electricity generated or displaced by your system. The number you receive depends on your system's size, your location's solar zone, and the years remaining until the scheme winds down in 2030.

Most households assign their STCs to their installer upfront as a point-of-sale discount. But STCs can also be created, held and sold separately — and that's where Sonergy comes in.
