Solar panel manufacture. View of a male technician monitoring the manufacture of an amorphous solar panel. The panel is being laser- cut from an array of amorphous solar cells. Solar cells convert light into electric currents. When sunlight hits the solar cells in the panel, electrons are released which can be converted into an electric current. Solar power can be harnessed as long as the Sun burns, and is hoped to be a major power source of the future. Amorphous as opposed to crystalline solar cells are far cheaper to manufacture. This is because they can be made without clean room conditions.
