Under the SRES, eligible solar power systems receive Small-scale Technology Certificates (STCs), which can be traded and sold to offset the upfront cost of the system. The number of STCs received is based on the size of the solar system and the geographic location, as well as the amount of electricity it is expected to generate over its lifetime.

STCs are created at the time of installation of the Solar power system and can be sold through the STC market to liable entities, such as electricity retailers, who are required to surrender a certain number of certificates each year to meet their renewable energy targets.

The price of STCs can vary depending on market demand and supply, and it is important for homeowners to keep track of the current market value to maximize their financial benefit. The value of STCs can also be influenced by government policies and incentives, so it is advisable to stay informed about any changes that may affect the market.

Overall, the STC scheme provides a valuable financial incentive for homeowners to invest in Solar power systems, making renewable energy more accessible and affordable for households across Australia.
