In the Australian solar industry, Small-scale Technology Certificates (STCs) are a form of government incentive that reduce the upfront cost of installing solar power systems, solar hot water, or heat pumps. Each STC represents the environmental benefit of generating renewable energy and reducing greenhouse gas emissions. The number of STCs a system is eligible for depends on its size, location, and the amount of electricity it will produce. Installers usually handle the process by assigning the STCs to a trading company, which then provides a discount to the customer at the point of sale—making solar more affordable for households and businesses.
