Use our Battery STC Calculator and learn how much you can earn for your project

Good news: the calculator already accounts for this for installs after 1 May 2026.
The returns provided are estimates and are subject to change on a daily basis. It is not guaranteed that you will receive the estimated price at the time of your transaction. Please consult with our team for more details.
STC calculations can change as regulations are updated. For the most accurate figures, refer to the official calculator on the CER website.
