solar module

A solar module, also called a photovoltaic module, is the basic element of a photovoltaic power plant system. The equipment creates a system of solar cells connected in series or in series-parallel - semiconductor elements in which the energy captured from the sun's rays is converted into electricity. The main task of the solar module is to generate direct current in this way, which will power all devices connected to the electrical network installed in the building. In most cases of photovoltaic modules, the semiconductor material is silicon (in the form of mono- or polycrystalline plates). Due to the limited access to this element, amorphous silicon, indium copper diselenide and cadmium telluride are also used more and more often. With the use of these chemical substitutes, the so-called thin-film modules. This type of equipment allows for ecological generation of electricity. When choosing a photovoltaic panel, it is worth paying attention primarily to the manufacturer and the guarantees it gives for the device. Modules usually have two types of warranty: for the product and the so-called. performance guarantee (linear). Important components of the selection decision are also the cell production technology used, certificates obtained and tests carried out (proving, among others, safety of use) as well as efficiency and technical parameters (usually included in the product card). The category includes polycrystalline photovoltaic solar modules and monocrystalline photovoltaic solar modules.
