Under the SRES, households and businesses that install eligible solar panel systems can create small-scale technology certificates (STCs), which can then be traded or sold to offset the upfront cost of the system. The number of STCs generated depends on the size of the solar panel system and the region where it is installed.

STCs are created based on the amount of electricity the Solar panel system is expected to produce over its lifetime, known as the deeming period. The deeming period is typically set at 15 years for residential systems and 10 years for commercial systems.

Once the Solar panel system is installed and commissioned, the system owner can assign the STCs to a registered agent, who can then sell them on the open market. The price of STCs fluctuates based on supply and demand, but in general, the more Solar panels that are installed, the lower the price of STCs.

By selling STCs, system owners can reduce the upfront cost of installing Solar panels, making it more affordable for households and businesses to transition to clean energy. This financial incentive is designed to encourage the uptake of Solar panel systems and reduce greenhouse gas emissions in Australia.
