Solar energy

Solar energy is used in various ways today, including: As a source of heat for making hot water, heating buildings and cooking; To generate electricity through the use of solar cells or heat engines; To take the salt away from sea water, making it drinkable.; To use sun rays for drying clothes and towels. It is used by plants for the process of photosynthesis.

Solar Photovoltaic Technology Basics | Department of Energy

What is photovoltaic (PV) technology and how does it work? PV materials and devices convert sunlight into electrical energy. A single PV device is known as a cell. An individual PV cell is usually small, typically producing about 1 or 2 watts of power. These cells are made of different semiconductor materials and are often less than the thickness of four human hairs.
