Solar PV Cost and Benefits


A solar PV system on your roof could generate an income and savings of up to £492 per year. (Please note figures quoted are valid until March 2017 and assume south facing, 30° pitch, no over-shading, 50% of energy generated is used and current energy cost of 12p/kWh)

The cost of a Solar PV system ranges from £3,300 for a 1.5kW system up to £6,300 for a full size 4kWp domestic system on a standard installation (inc. VAT).

The payback time will vary depending on the cost of the system and the output that can be achieved but it generally works out at around 8-10 years for a full size domestic system.

However, the performance of solar PV systems is impossible to predict with certainty due to the variability in the amount of solar radiation (sunlight) from location to location and from year to year.
