Small-scale Technology Certificates (STCs): This is a federal government scheme that provides rebates for small-scale renewable energy systems, including solar panels. The number of STCs granted depends on the size of the solar system and its location. These certificates can be sold to energy retailers, who are required by law to buy a certain number of certificates each year. The value of STCs can fluctuate, depending on supply and demand.

STCs are designed to make renewable energy systems more affordable for consumers by reducing the upfront costs of installation. By selling STCs to energy retailers, homeowners can offset some of the cost of installing Solar panels or other renewable energy systems.

The number of STCs granted for a particular system is based on its capacity and location, with systems in areas with higher Solar radiation receiving more certificates. The value of STCs can also vary depending on market conditions, with prices typically higher during periods of high demand.

Overall, the STC scheme helps to promote the uptake of renewable energy systems by providing financial incentives for consumers to invest in clean energy technology. This ultimately helps to reduce greenhouse gas emissions and move towards a more sustainable and environmentally friendly energy future.
