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.
