The solar energy represent today an exclusive opportunity from different point of view. The solar energy can be used to produce electricity or to create calories in a natural way, avoiding the generations of dangerous emissions and the energy waste. For solar energy is intended the energy, thermal and electric, produced exploiting directly the energy produced by the sun towards the earth.

In every moment the sun transmits on the earth 1367 watt for m².

The two principal technologies that convert the sunbeam in exploiting energy are:

• The solar thermal panel exploit the sunbeam to heat a special liquid, contained in the structure that gives heat through an inverter, to the water inside the tank.

• The photovoltaic panel exploit the particular asset of the semiconductor element to produce electric energy when stressed by the light.
