NOVELTY - The arrangement (1) has a profiled rail (4) comprising a contact surface (41). Supporting devices (5, 6) are connected with the profiled rail and comprise two support surfaces (7, 8), respectively. A bottom side of a plate module (3) rests on the support surfaces of the supporting devices. The supporting devices support the module and are spaced from a substrate (2). The supporting devices comprise holding pins, respectively. The pins lock a movement of the module in a direction transverse to a longitudinal extension of the profiled rail and a direction turned away from the rail.    USE - Plate module arrangement e.g. photovoltaic module arrangement and solar thermal energy module arrangement, for use in a photovoltaic and/or solar thermal energy system for mounting a plate module on a substrate e.g. flat roof and free surface, of a building for generating heat and electric power from solar energy.    ADVANTAGE - The holding pins of the supporting devices lock the movement of the plate module in the direction transverse to the longitudinal extension of the profiled rail and the direction turned away from the profiled rail, so that the plate module is locked without utilizing an additional attaching unit, thus preventing slipping of the plate module, and hence reducing weight and cost of the arrangement while improving function of the arrangement. The plate module rests upon the support surfaces of the supporting devices and runs diagonally to the substrate, thus enabling the arrangement to utilize the sunlight in a better manner. The supporting devices are designed as the punching or bending parts, thus manufacturing the supporting devices in a simple and inexpensive manner.    DETAILED DESCRIPTION - The supporting devices are designed as punching or bending parts.
