Solar PV Cost and Benefits

A solar PV system on your roof could generate savings of up to £400 per year. (Please note figures assume south facing, 40° pitch, no over-shading, 75% of energy generated is used and current energy cost of 14p/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, the output that can be achieved and how much of the generated energy you can use.

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.
