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 total amount of solar energy received on Earth is vastly more than the world's current and anticipated energy requirements. If suitably harnessed, solar energy has the. As a renewable energy source, outdoor solar energy presents numerous advantages, making it an efficient alternative to non-renewable energy sources. Over time, people developed technologies to.
