A solar panel is a technology that transforms sunlight into electrical energy using the photovoltaic effect. It consists of numerous photovoltaic (PV) cells made from semiconductor materials, usually silicon. When sunlight strikes these cells, it energizes electrons, generating an electric current that can be harnessed to supply power to homes, businesses, or various devices.

1. Photovoltaic Cells: These are the core components of a solar panel, typically crafted from silicon. They are responsible for converting sunlight into electricity.
Encapsulant: This refers to protective layers, often made of EVA, that shield the cells from environmental damage and degradation.
Glass Layer: Generally made of tempered glass, this layer safeguards the solar cells from external elements while allowing sunlight to penetrate effectively.
Backsheet: Positioned at the rear of the panel, this layer protects the electrical components and keeps moisture from reaching the cells.
Frame: Usually constructed from aluminum, the frame provides essential structural support and facilitates the easy installation of panels on rooftops or other surfaces.
Junction Box and Cables: The junction box houses the wiring needed to connect the solar panel to a larger system, such as an inverter or battery, with cables extending from this box to complete the electrical circuit.
