PV panels, or solar electric panels, transform the solar radiation directly into electricity. "Photo" refers to light and "voltaic" to electricity.
Solar energy in the UK is far greater than most people imagine. By tilting the surface to an angle the amount of solar radiation falling on it will be greater than that falling on a flat surface in this country. Fortunately, the average tilt of a UK house roof is about the optimum for receiving solar energy. A PV system comes with many benefits:
| » |
It increases the value of your property |
| » |
It reduces your electricity bills |
| » |
You contribute to helping the environment |
| » |
No planning permission is needed |
| » |
Low maintenance is needed |
| » |
Surplus of electricity could be sold back to energy companies |
| » |
You have your own independent power source |
The cost of a PV solar panel is approximately £400 per M² installed. A typical roof solar panel can absorb and deliver 540kW per annum. An average solar panel package (buying & installing) costs around £7,000. With the grants that are available you are likely to pay only £ 4,000 to £ 5,000 for the installation of a solar panel system.
