NOVELTY - Plastic carrier (1) for a photovoltaic module (3) in the form of a one-piece molded plastic element having a rectangular or square contour, comprises: elongated rainwater evacuation elements (10), which extend along an edge (11) of plastic carrier conducting in an oblique position of the plastic carrier with a gradient along the lateral direction of rain water in the direction of the gradient; a molding in the form of an elevation (12) on the upper side, whose edge runs at the border of the plastic carrier at a distance; and locking elements for latching fixation of the photovoltaic module.    USE - The plastic carrier is useful for a photovoltaic module.    ADVANTAGE - The plastic carrier can be fastened directly on a roof substructure and allows fastening of photovoltaic modules without screwing.    DETAILED DESCRIPTION - Plastic carrier (1) for a photovoltaic module (3) in the form of a one-piece molded plastic element having a rectangular or square contour, comprises: elongated rainwater evacuation elements (10), which extend along an edge (11) of the plastic carrier conducting in an oblique position of the plastic carrier with a gradient along the lateral direction of rain water in the direction of the gradient; a molding in the form of an elevation (12) on the upper side, whose edge runs at the border of the plastic carrier at a distance, where the mounting points are arranged on the elevation to guide a fastener through the plastic carrier and to be fixed to a substructure; and locking elements for latching fixation of the photovoltaic module. INDEPENDENT CLAIMS are also included for:    (1) producing the plastic carrier, comprising preparing the plastic carrier in an injection molding or injection stamping process and utilizing a hot channel system having many hot channel nozzles for the distribution of melt;    (2) a photovoltaic module, which is designed for fixing on a plastic carrier, comprising at least one photovoltaically active layer covering the glass pane, which forms the front side of the photovoltaic module, where photovoltaic module is frameless. The module carriers are glued on front side of the photovoltaic module, which is opposite to the rear side. The module carrier in each case has two locking elements at opposite ends, which are resiliently movable. The locking elements respectively exhibit locking surfaces, which have a component lying parallel to the surface of the glass pane of the surface normal such that the system is activated by locking surfaces on the fixed elements of a locking device in the direction parallel to the surface of the glass sheet. The module carrier comprises additional locking elements comprising locking surfaces, which include a component of the surface normal parallel to the direction of the surface normal of the front or rear side, to block a movement in the direction of the surface normal of a holder, which is in contact with locking element; and    (3) a photovoltaic installation system comprising the plastic carrier and photovoltaic module, where a locking of the photovoltaic module, both in the horizontal direction along the front or rear side of the photovoltaic module and in perpendicular direction, and a complete locking of the photovoltaic module in all directions is activated by locking elements of plastic carrier and photovoltaic module, with which the locking of the photovoltaic module on the plastic carrier is carried out by placing the photovoltaic module in an initial position and lateral displacement of the photovoltaic module on the plastic carrier is carried out up to the locking position.
