The tariff for a small domestic solar installation will be 16p per kilowatt hour, down from 21p, and will decrease on a three-month basis thereafter, with pauses if the market slows. All tariffs will continue to be index-linked in line with the retail price index (RPI) and the export tariff will be increased from 3.2p to 4.5p. The new tariffs are expected to give a return on investment (ROIs) of more than 6 percent for most installations, and up to 8 percent for the larger bands.
The scheme lifetime will be reduced from 25 years to 20 years for new solar installations.
- Tariffs for solar PV installations from 1 August to be 16p/kWh for household scale solar PV installations. Tariffs for larger installations are also to be reduced
- Multi installation tariff will be increased to 90 percent of standard tariff. Organisations with more than 25 PV installations will get 90 percent of the standard applicable tariff, increased from 80 percent
- Average tariff reductions of 3.5 percent every three months. Reductions will be bigger (up to 28 percent) if there is rapid uptake.
- Tariff cuts will be skipped (for up to two quarters) if uptake is low. Uptake in three different bands (domestic (size 0-10kW), small commercial (10-50kW) and large commercial (above 50kW and standalone installations) will determine the quarterly reductions within those bands.
