What are solar panels made of and how do they work? Solar cells are made primarily from silicon, a chemical element with conductive properties. Exposure to light changes silicon’s electrical characteristics, which generates an electric current. A cell is a small square of silicon (about 6” x 6” or 5" x 5") with electrical contact plates on the face. Solar panels are made by laying out a grid of th...
