Solar panels are made up of individual solar photovoltaic (PV) cells, which are thin slices of silicon that typically measure 6 inches long by 6 inches wide. Each solar cell converts sunlight into electricity in what''s called the photovoltaic effect. Multiple solar cells are assembled together to form a single rectangular shaped panel.
Solar panels can only capture at most a quarter of the sun''s energy hitting them and convert it into electricity—a great improvement since the first photovoltaic cell was created in 1839—but
