A single solar cell can produce only a small amount of electricity. In those cases where more electrical power is needed, a large number of solar cells are joined together in series. This group of solar cells is called a 'solar cell panel'. Thus, a solar cell panel consists of a large number of solar cells joined together in a definite pattern.
