NOVELTY - Solar module (1) comprises a carrier layer, a first intermediate layer arranged above the carrier layer, a crystalline solar cell (4) arranged above the first intermediate layer, a second intermediate layer arranged above the crystalline solar cell, a front screen (6) made of a glass, which is arranged above the second intermediate layer (7), and an edge reinforcement structure. The edge reinforcement structure dominates the front screen, and has a water drainage channel at each corner of the solar module, which connects the inner side with the outer side of the edge reinforcement structure.    USE - The solar module is useful on a flat roof, preferably on a metallic flat roof of a building or a vehicle for movement, on water, on land or in the air, where the flat roof exhibits a pitch surface of 1-23.1%, preferably 5-8.8% (claimed).    ADVANTAGE - The device can be easily installed without requiring the introduction of a hole into the front screen, which maintains the stability of the solar module.    DETAILED DESCRIPTION - Solar module (1) comprises (a) a carrier layer, (b) a first intermediate layer arranged above the carrier layer, (c) at least one crystalline solar cell (4) arranged above the first intermediate layer, (d) a second intermediate layer arranged above the crystalline solar cell, (e) a front screen (6) made of a glass with a thickness of 0.85-2.8 mm, which is arranged above the second intermediate layer (7), and (f) an edge reinforcement structure. The edge reinforcement structure dominates the front screen by a height of at least 0.5 mm, and the edge reinforcement structure has at least one water drainage channel at each corner of the solar module, which connects the inner side and the outer side of the edge reinforcement structure. INDEPENDENT CLAIMS are also included for:    (1) a flat roof with the solar module, comprising a roof cladding with a roof pitch of 1-23.1%, and at least one solar module arranged on the roof cladding, where the roof cladding and the solar module are at least partially connected to one another by at least one adhesive layer and/or connecting agent; and    (2) manufacturing the solar module, comprising (i) arranging the first intermediate layer above the carrier layer, (ii) arranging at least one crystalline solar cell on the first intermediate layer, and connecting the crystalline solar cell with a collecting pipe, (iii) arranging the second intermediate layer above the crystalline solar cell and the front screen above the second intermediate layer, (iv) laminating the carrier layer, the first intermediate layer, the crystalline solar cell, the second intermediate layer and the front screen at 100-170 degrees C, and (v) arranging the edge reinforcement structure above the front screen, at least on the projection of the carrier layer.
