The photovoltaic effect is the phenomenon discovered by Edmond Bequerel in 1839, which consists of the physical characteristics of some semi-conductive materials that, under the right conditions, allows them to produce electrical energy provided by exposure to solar radiation.

The photovoltaic module: The photovoltaic cells are electrically connected in a series of rows and columns, thereby forming a module. The cells are mechanically protected from atmospheric agents by a glass pane placed at the front of the module and by insulating materials and plastics placed posteriorly.
