Solar energy calculator
How much can you save?
We have used a typical example solar panel installation in Devon to work out how much energy, on average, households or businesses can save with their solar panels.
|Number of panels||Annual benefit and savings||Return on investment including FIT payments and saving on electricity||Return on investment FIT only|
To work out the average annual saving, return on investment and FIT return, we have used the below criteria…

Price paid for electricity: £0.152 pence per kWh (residential – cost include Standing Charge), £0.108 pence per kWh (commercial), FIT rate valid from to 31.03.2016, saving: 50% of the electricity produced used in the building.
