The Government offers Small-scale technology certificates (STC’s) for installation of residential solar PV systems.

The number of STC’s received is dependent on the size of the system purchased and the state that the system is bought in.

Solar Companies will often give you the option of transferring your STCs to them for an upfront discount on your PV system. The value of discount offered may fluctuate over time as the value of STCs varies like a stock.

Alternatively you have the option to retain the STCs yourself and sell them through the Renewable Energy Certificate (REC) clearing house. However, this option is not usually taken up because of the complexity and time taken in selling STCs through the clearing house.
