TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The elevation is in the form of a vertical crease, which surrounds an opening. The beadings on the edge are arranged on both sides of the elevation as rainwater evacuation elements, where the upper and lower sides of the beads are shaped complementarily, so that two laterally displaced plastic carriers are sequential with interlocking corrugations. The plastic carrier is made of a thermoplastic molding composition. The thermoplastic molding composition is based on polyamide having a viscosity number of 50-250, preferably 80-150 ml/g, determined according to ISO 307 EN on a 0.5% solution of the polyamide dissolved in 96 wt.% sulfuric acid at 25 degrees C. The thermoplastic molding composition comprises: 0-70 wt.%, preferably 20-50 wt.% of fibrous or particulate fillers; and pigments and/or stabilizers to improve the weather resistance and fire performance. The plastic carrier is stackable, where the upper and lower sides are partially complementary such that the total amount of the two stacked plastic carrier is less than twice the height of a single plastic carrier during superimposing the plastic carrier with its bottom having aligned edges on the upper side of an additional plastic carrier. The plastic carrier comprises locking elements for locking in the direction perpendicular to the upper side of the plastic carrier, which are remotely located at a distance of more than one sixth, preferably at most one tenth of the longest dimension of the side of the plastic carrier and the nearest mounting point. At least one cable guide element is provided in the form of a semi-open cable duct, which extends above a base plane of the plastic carrier. The module carrier is formed as hand grip. The plastic carrier comprises a storage space and an abutment edge adjacent to the storage space, which are positioned such that the photovoltaic module is positioned in abutment against the abutment edge, and storage on the storage surface is positioned in a defined starting position for the lateral displacement of the photovoltaic module along the plastic carrier for the mutual locking of the locking elements of plastic carrier and photovoltaic module. The width of the photovoltaic module is greater in the direction of locking than the width of the plastic carrier in this direction away from the displacement path between the initial position and the locking position.
