  • Solar power generation is the light

    Solar power generation is the light

    Solar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Solar panels use the photovoltaic effect to convert light into an electric current. The two dissimilar semiconductors possess a natural difference in electric potential (voltage), which causes the electrons to flow through the external circuit, supplying power to the load. Sunlight is composed of photons, or particles of solar energy. There are two forms of energy generated from the sun for our use – electricity and heat.
