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. Concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight to a hot spot, often to drive a steam turbine.

Solar power 101: What is solar energy? | EnergySage

There are two main types of solar energy: photovoltaic (solar panels) and thermal. The “photovoltaic effect” is the mechanism by which solar panels harness the sun''s energy to generate
