The value of STCs depends on various factors, such as the size of the solar system, its location, and the market demand for STCs. The value of STCs is usually applied as a discount on the upfront cost of the solar power system. The number of STCs that can be claimed for a system is based on its estimated power generation over a 15-year period.

The price of STCs fluctuates based on supply and demand in the market. As a result, the value of STCs can change over time. It is important for consumers to keep up to date with the current value of STCs when considering purchasing a Solar power system.

In addition to the value of STCs, other factors such as government incentives, rebates, and feed-in tariffs can also impact the overall cost and benefits of installing a Solar power system. It is recommended to consult with a Solar provider or energy consultant to assess the financial implications of installing a Solar power system and to determine the potential savings and return on investment.
