Under the SRES, eligible solar power system owners receive Small-scale Technology Certificates (STCs) for the amount of electricity their system is expected to generate over its lifetime. These STCs can then be sold to electricity retailers, who are required by law to purchase a certain number of STCs each year.

The amount of STCs received depends on factors such as the size of the system and its location. The price of STCs can fluctuate based on market demand, but generally provides a financial incentive for homeowners to invest in Solar power systems.

By participating in the STC scheme, Solar power system owners can offset the upfront cost of installing Solar panels and reduce their payback period. This helps make Solar power more affordable for households and encourages the uptake of renewable energy in Australia.

Overall, the SRES and STC scheme play a crucial role in supporting the growth of the Solar industry and reducing greenhouse gas emissions in Australia.
