STCs are created when eligible Solar systems are installed, and can be traded on the open market. The value of STCs fluctuates based on supply and demand, but generally provides a substantial discount on the upfront cost of installing a Solar system.
To claim STCs, homeowners must use a Clean Energy Council accredited installer and ensure the system meets certain standards and requirements. The installer will then provide the homeowner with a certificate of compliance, which can be used to claim the STCs.
The amount of STCs that can be claimed for a Solar system also decreases each year as part of the deeming period, which is currently set to end in 2030. This means that homeowners who install Solar systems earlier will receive more STCs than those who wait until later.
Overall, the SRES program aims to incentivize the installation of Solar systems by providing financial support to homeowners, reducing greenhouse gas emissions, and helping Australia transition to a more sustainable energy future.
