Design and Sizing of Solar Photovoltaic Systems
1.1.1. Solar Cell The solar cell is the basic unit of a PV system. A typical silicon solar cell produces only about 0.5 volt, so multiple cells are connected in series to form larger units called PV modules. Thin sheets of EVA (Ethyl Vinyl Acetate) or PVB (Polyvinyl Butyral) are used to bind cells together and to provide weather protection.
