What is tariff degression and how would it apply to my system?
The level of the tariff applicable to systems installed in the future will decrease with time, according to annual degression rates. The degression rate is used only to determine the tariff applicable to the system based on its registration date – once you’ve been allocated a tariff that rate would apply for the full 20 or 25 years. [For example: If you install a 5kW PV system in June 2010 you would receive 36.1p/kWhr for 25 years until June 2035.
