A solar PV module, or solar panel, is composed of eight primary components, each explained below: 1. Solar Cells Solar cells serve as the fundamental building blocks of solar panels. Numerous solar cells are combined to create a single solar panel.
The most crucial component of the solar panels is the photovoltaic (PV) cells responsible for producing electricity from solar radiation. The rest of the elements that are part of a solar panel protect and give firmness and functionality to the whole. The structure of a solar panel is divided into different parts or components.
Within the components that make up a photovoltaic system, the structures of the photovoltaic panels are passive components that facilitate the installation of the solar PV modules. Solar mounting structures must constantly withstand outdoor weather conditions. The solar panel mounting structure fixes its position and stays stable for years.
Photovoltaic cells are the most critical part of the solar panel structure of a solar system. These are semiconductor devices capable of generating a DC electrical current from the impact of solar radiation.
A PV module consists of a number of interconnected solar cells encapsulated into a single, long-lasting, stable unit. The key purpose of encapsulating a set of electrically connected solar cells is to protect them and their interconnecting wires from the typically harsh environment in which they are used.
The cells are interconnected with each other by a thin copper tape coated with a tin alloy, called ribbon; The front glass is the heaviest part of the photovoltaic module and it has the function of protecting and ensuring robustness to the entire photovoltaic module, maintaining a high transparency.
