Small-scale Technology Certificates (STCs): STCs are a form of financial incentive given to individuals or businesses that install small-scale renewable energy systems, such as solar panels. The number of STCs received depends on the size and location of the system, as well as the amount of electricity it is expected to generate over its lifetime. These certificates can then be sold to electricity retailers, who are required by law to purchase a certain number of certificates each year.

STCs help to offset the upfront costs of installing renewable energy systems and encourage the adoption of clean energy technologies. They also help to reduce greenhouse gas emissions by promoting the use of renewable energy sources. STCs are an important part of Australia’s Renewable Energy Target (RET) scheme, which aims to increase the use of renewable energy sources in the country.
