Photovoltaic solar modules
The PV module consists of many PV cells connected in parallel to increase the current and series to produce a higher voltage. 36 mobile modules are an industry standard for the production of large quantities. The module is inserted with tempered glass (or some other transparent material) on the front surface, and with a protective and waterproof material on the back surface. The edges are sealed for protection against atmospheric influences, and often there is an aluminum frame that keeps everything together in the mounting unit. In the back of the module there is a junction box or wire leads that provide electrical connections.
