Claim:
A fastening system for a plate-shaped structural element on a pitched roof having a roof covering, comprising: a frame of profiled beams configured to border, in a water-tight manner, the plate-shaped structural element to form a module, the module being configured to fully replace the roof covering of the pitched roof, the frame of profiled beams including an eaves-side cross beam and a ridge-side cross beam, each of the eaves-side cross beam and ridge-side cross beam having profiles that match each other and engage each other, the profiles forming a rain-proof joint such that an adjacent module partially overlaps in the longitudinal direction only in the region of the eaves-side and ridge-side cross beams, the eaves-side cross beam having a top side provided with a mounting that surrounds an edge of the plate-shaped structural element in a U-shaped manner, and having a bottom side provided with a support for fastening to the roof structure, the support comprising a web that extends from a lower limb of the mounting and leads to the support, a protrusion that extends beneath the mounting from a side of the web so that a channel is defined by the mounting, the web, and the protrusion, and the ridge-side cross beam having an extension that can be inserted into the channel of the eaves-side cross beam of the adjacent module, wherein the ridge-side cross beam has an angled-off portion that rests on the support of the eaves-side cross beam of the adjacent module.
