Question
What is solar energy? How is the solar energy used to generate electricity in a solar power Plant?
Solution
The energy obtained from Sun is called solar energy.
A solar power plant is a device in which heat energy of sun is used to generate electricity. It consists of a large number of concave reflectors, at the focus of which there are black painted water pipes. The reflectors concentrate the heat energy of the sun rays on the pipes due to which water inside the pipes starts boiling and produces steam. The steam thus produced is used to rotate a steam turbine which drives a generator producing electricity.
