Solar Energy Calculator

The Solar Energy Calculator estimates the savings you could make by installing a solar PV system and the payment you could receive from the domestic Feed-in Tariff (FIT) scheme for eligible PV installations.

Note that the Department of Energy and Climate Change (DECC) has released a consultation on a review of the Feed-in Tariff scheme. This consultation proposed a number of changes to the scheme including changes to generation tariffs. For more information visit our FITs page.
