Photovoltaic solar energy is a renewable energy source obtained directly from solar radiation using solar panels which transform it into electrical energy.
The process starts when solar light falls on one of the faces of photoelectric cells, which make up solar panels, producing an electrical potential difference between both faces and making electrons jump from one place to another, thereby generating electrical energy that is transported to the distribution network and then to consumption points.
Besides not emitting pollutant or greenhouse gases during energy generation, another main advantage of this technology is the fact that is modular. This means panels can be used for self-consumption ―to provide power supply to houses or buildings― or to supply the electrical grid through large power plants like Enel’s Planta Solar Rubí .
