Small-scale Technology Certificates (STCs): STCs are a form of government subsidy that can be claimed when installing small-scale renewable energy systems, including solar panels. The number of STCs a system is eligible for depends on the size of the system and the location. These certificates can be sold to electricity retailers, who are required by law to purchase a certain number of STCs each year.

STCs help reduce the upfront cost of installing renewable energy systems, making them more affordable for homeowners and businesses. They also help reduce greenhouse gas emissions by incentivizing the use of clean, renewable energy sources. STCs are an important tool in Australia’s efforts to transition to a low-carbon economy and meet its emissions reduction targets.
