A solar panel, also known as a photovoltaic (PV) panel, is a device that converts sunlight into electricity through the photovoltaic effect. Hereâ??s a detailed description of solar panels: Structure and Components 1. Photovoltaic Cells: * Solar panels are made up of multiple photovoltaic cells arranged in a grid-like pattern on a rigid frame. * Each cell is typically made from silicon, the most common semiconductor material used in solar panels. 2. Encapsulation: * Photovoltaic cells are encapsulated between a front glass cover and a backsheet or encapsulant material. * The front cover is tempered glass designed to protect the cells from environmental factors while allowing sunlight to pass through.
