A Photovoltaic(PV) module which is generally termed as a solar panel is an assembly of photovoltaic cells electrically connected to each other and mounted on a laminated frame. The solar cells are primarily made up of silicon material which absorbs the photons emitted by the sun. There are three major types of PV modules. Mono-crystalline Poly-crystalline Thin-film Each solar PV module type has its own unique features. These PV modules also vary based on how they are manufactured, their appearance, performance, costs, etc.
