PV Solar Panel Payback Calculator

We've made a PV Solar Panel Payback Calculator which you can use to work out what return you could get by investing in solar panels versus leaving the cash in a savings account.

Here's an example graph for a 3.76kWh system with the following assumptions:
Cost of system = 3.76 x 4000 = £15040
System output: 3008 kWh/year
Tax rate: 40%
Savings rate: 5%
RPI: 3%
Annual increase in elec cost: 6%
Percentage of generated electricity which is used: 50%
Cost of a unit of electricity: 12p
And we'll won't treat the solar panels as an asset (i.e. we'll say they have 100% initial depreciation).
