Solar energy. Solar panels, composed of thousands of individual spherical solar cells, which convert solar radiation directly into electricity. The solar cells are made with thin layers of semiconductors such as silicon which, when struck by sunlight, liberate bound electrons. These are collected by a grid of metal conductors, placed on the solar cell, to form an electric current. In this way electricity is obtained with no pollution; solar power plants also need minimal maintenance. This solar power station is situated on one of the Tremiti Islands, Italy, and its energy output (100 kW peak) is used to run a desalination plant.
