These STCs can be sold to electricity retailers or other entities who have a legal obligation to purchase a certain number of them each year. The price of STCs is determined by market forces, and it can fluctuate.
The number of STCs a Solar system is eligible for is calculated based on the system’s capacity (in kilowatts) and the location where it is installed. The Clean Energy Regulator (CER) provides an online calculator to determine the number of STCs for a specific system.
The value of STCs can be used to offset the upfront cost of installing a Solar system. The installer typically helps the customer claim the STCs and deduct their value from the total installation cost. Alternatively, customers can choose to sell the STCs themselves on the open market.
It is important to note that the value of STCs is subject to change, and there have been discussions about reducing or phasing out the scheme in the future. The SRES is set to continue until at least 2030, but any changes to the program may impact the financial incentives available for Solar installations in Australia.
