Question

Explain solar panel and its working with a neat sketch.

Accepted Answer

A solar panel consists of many solar cells joined together in a definite pattern. When sunlight falls on the surface of a solar cell, it makes the loosely held electrons in the silicon atoms move due to which a current begins to flow in the wires connected to the top and bottom of the solar cell.
The strength of current rays produced depends on the intensity of the light and the efficiency of the solar cell. A potential difference of about $0.5 V$ is generated between the top and bottom surface of a solar cell.

A single solar cell can produce only a small amount of electricity. To produce more electricity, we need to use more solar cells, and these are connected in series. The groups of solar cells are called ‘solar panel’.
