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).

Payback for Solar pv

We've written a squidoo lens on how to evaluate payback of solar pv panels in the UK. We cover how the government feed in tariffs work. And show how to calculate whether solar pv makes sense for you.

Extract "The UK government has recently introduced Feed-In-Tariffs (FiTs). FiTs provide tax-free, index-linked payments for 25 years. These payments mean that it can actually make financial sense to install photovoltaic (PV) solar panels on your roof. It won't make you rich, but when considered along with the environmental benefits it can be worthwhile.

The potential payout is dependent on many factors. We'll take you through the factors and give figures for some samples systems so you can get an idea of how much money you can make from solar PV."
