  • Solar power is the conversion of sunlight into electricity,
    either directly using photovoltaics , or indirectly using
    concentrated solar power . Concentrated solar power systems
    use lenses or mirrors and tracking systems to focus a large
    area of sunlight into a small beam. Photovoltaics convert
    light into an electric current using the photovoltaic effect.
