STCs are created when a Solar system is installed and generate a certain number of certificates based on the amount of renewable energy the system is expected to produce over its lifetime. These certificates can then be sold to electricity retailers or other entities who have obligations under the Renewable Energy Target, providing a financial incentive for homeowners to invest in Solar energy.
The value of STCs can fluctuate based on market demand and supply, so it is important for homeowners to keep track of the current market prices to maximize the return on their investment. The amount of savings that can be achieved through the sale of STCs will vary depending on the size of the system and the location of the installation, but in general, homeowners can expect to recoup a significant portion of the upfront costs through the sale of certificates.
Overall, the availability of STCs under the SRES has played a key role in driving the uptake of Solar energy in Australia, making it more affordable for homeowners to invest in clean, renewable energy. By providing a financial incentive for Solar installations, the SRES has helped to reduce greenhouse gas emissions, lower electricity bills, and create jobs in the renewable energy sector.
