S Carre Services has recently gained an MCS Qualification to install Solar PV Panels.
PV cells are made from layers of semi-conducting material, usually silicon. When light shines on the cell it creates an electric field across the layers. The stronger the sunshine, the more electricity is produced. Groups of cells are mounted together in panels or modules that can be mounted on your roof.
The power of a PV cell is measured in kilowatts peak (kWp). That's the rate at which it generates energy at peak performance in full direct sunlight during the summer. PV cells come in a variety of shapes and sizes. Most PV systems are made up of panels that fit on top of an existing roof, but you can also fit solar tiles.
The average domestic solar PV system is 3.5 to 4kWp and costs around £9,000 (excluding GST at 5%), with the typical cost ranging from £7,500 to £11,500.
Other factors that affect PV installation costs are:
