Question

Give an account of the use of solar energy.

Answer 1

Solar energy is the energy that we receive from the sun. It is readily available in nature and in unlimited quantities.
While there are several ways to obtain solar energy, one way is by the use of solar cells or photovoltaic panels. These panels are made from very thin semiconducting materials which, when exposed to sunlight, use the heat and light of the sun to shake the electrons loose and create an electric current.
Solar cells are used for lighting street lamps, electronic calculators, watches, smartphones, cameras, traffic signals, water pumps, and home lighting. Solar energy is being used to heat ovens, cook food, and heat water.
