The feed-in tariffs for solar PV energy are determined annually by a decision of the Energy and Water Regulatory Commission (EWRC) on July 1. The new tariff applies to all new investments in solar PV systems which are connected to the grid after this date. Its value is fixed for the term of the Power Purchase Agreement (until 2035). That is, at whatever price you sign a contract, it will remain the same until the end of 2035.
