Abstract: A module mounting and a collector module system are described. The module mounting and the collector module system have a plurality of collector modules mounted on the module mounting, having at least two support units each with at least two lateral supports. The lateral supports can receive between them at least one collector module, and the lateral supports of adjacent support units are connected together in an articulated way by means of first hinges. Provided in an articulated way at each lateral support is at least one elongated connecting element. At least one of two adjacent connecting elements is connected by second hinges which differ from the first hinges. Two adjacent connecting elements of adjacent lateral supports are connected together in an articulated way by third hinges such that the module mounting is foldable.
