STCs, or Small-scale Technology Certificates, are a type of Rebate available for residential and small-scale commercial Solar installations with a capacity of up to 100 kilowatts. These certificates are created based on the expected electricity generation of the Solar system over a 15-year period.
For every megawatt-hour of electricity that the Solar system is expected to generate, a certain number of STCs are received. The exact number of STCs depends on factors such as the size of the system, its location, and the anticipated electricity generation.
The purpose of these certificates is to provide a financial incentive for the installation of small-scale Solar systems. Once received, these certificates can be sold to electricity retailers or brokers in order to offset the cost of the Solar system. This allows individuals or businesses to receive a financial benefit for the clean energy they generate.
Overall, STCs serve as a way to encourage the adoption of Solar energy by providing a means to reduce the upfront costs of installation.
