Solar energy is the energy produced by the Sun and it is converted to useful energy by human beings, either to produce electricity or heat something (like their main applications). Each year the Sun throws four thousand times more energy than they consume, so their potential is almost unlimited. The intensity of energy available at a given point on earth depends on the day of the year, time and latitude. Furthermore, the amount of energy that can be collected depends on the orientation of the receiver. Today it is one of the most developed renewable energy and ethod used in the world.
