Photovoltaic energy, or solar cells in popular terms, is probably the cleanest and safest method of power generation.
The principle behind photovoltaics is fairly simple. Sunlight is converted into electricity by photovoltaic cells; semiconductor devices which contain no liquids, corrosive chemicals or moving parts.
As a solar energy technology, photovoltaics has numerous environmental benefits: it does not pollute, it is silent, solar cells require little maintenance and as a domestic source of electricity it makes energy security totally independent of foreign suppliers.
Photovoltaic systems can be used as an independent power supply or they can be connected to the grid.Go back
