Modular photovoltaic system

A modular photovoltaic system comprises flat modules with two photovoltaic panels—preferably bifacial—arranged vertically in a rectangular frame consisting of two posts and two crossbeams. One of the crossbeams supports a cable guiding device for electrically connecting an adjacent photovoltaic module. The modules also have a charging socket for electric vehicles and can be used advantageously for the construction or conversion of parking spaces for vehicles.
