Small-scale Technology Certificates (STCs): STCs are a form of tradeable certificates that can be created when eligible solar panels, solar water heaters, or heat pump systems are installed. The number of STCs received depends on the system size, location, and the amount of clean energy it is expected to produce over its lifetime. These certificates can be sold to electricity retailers or other entities to offset the cost of the solar system.

STCs are a key incentive for households and businesses to invest in renewable energy systems, as they provide a financial benefit that helps reduce the upfront cost of installation. The value of STCs can fluctuate based on market demand and government policies, so it is important to take advantage of them while they are available.

In Australia, the Small-scale Renewable Energy Scheme (SRES) governs the creation and trading of STCs for small-scale renewable energy systems. Installers of eligible systems can create STCs on behalf of the system owner and then sell them on the open market. The value of STCs is typically higher in areas with higher electricity prices and greater demand for renewable energy.

Overall, STCs play a crucial role in promoting the uptake of Solar and other renewable energy technologies, helping to reduce greenhouse gas emissions and transition towards a cleaner energy future. By taking advantage of STCs, households and businesses can make a positive impact on the environment while also saving money on their energy bills.
