Photovoltaic technology enables the direct, immediate transformation of solar energy into electricity with no use of any kind of fuel.

It exploits the so called 'photoelectrical effect', that is the capacity of certain properly treated, 'doped', semiconductors, to generate electricity when exposed to light radiation.

Part of the solar energy, after passing through the atmosphere, reaches the ground at an intensity of about 1.000W/m2 (irradiation to the ground in good weather conditions and Sun at midday). This huge flow of energy that reaches the Earth is about 15,000 times the current world energetic consumption.

But only a part of this energy can be used by photovoltaic plants.
