The use of this energy is fairly new and is done mainly in two ways. One of them is based on reflecting the sun's rays so they come together in one place.
is usually achieved by means of mirrors when they have their axis oriented to the Sun concentrate all the rays on them, lie in a focus. Thus, we come to the point that depending on the size of the device, known to reach temperatures several thousand degrees. The other way to exploit this energy is transformed directly into electrical energy, which is accomplished by using photocells (electronic device that permit 
and transform light energy into electricity through the photovoltaic effect) that mounted correctly, provide a very useful power (used to move or activate machines and instruments).

These devices also being increasingly applied in the Earth, equipped with large numbers of satellites and other spacecraft.
