What is photovoltaics?

Solar modules convert sunlight directly into electricity. The solar cells are made of pure silicon, which achieves semiconductor properties through targeted doping. When sunlight hits the solar cell, an electric voltage develops between its upper and lower surface. Connecting the two surfaces creates an electric current that is released by the cell. In order to produce the desired voltage, several cells are connected in series. The desired current is achieved by connecting the cells in parallel.

The cells are mounted in a solar module for safety reasons. The solar module consists of a tempered glass pane, covering the cells placed in rows and protected at the rear by a plastic layer. The electrical connections of the cells lead out of the module to an external connection box.
