In the 1 to 7 and 9 shown embodiment of a solar module assembly is primarily intended for installation on the roof of a building and serves to one or more rows of solar modules 1 each to keep in an oblique position. For holding the solar modules 1 is a carrying device 2 provided, which will be described in detail below.

The carrying device 2 can be roughly divided into two parts. A first part 3 adjoins the exterior of the building, ie on the roof 4 while a second part 5 the solar modules stops and in turn on the first part 3 is attached.

In the present embodiment, the first part comprises 3 a variety of tubs 6 on protective mats 7 rest on the roof 4 are designed. Every tub 4 is formed by a sheet metal profile, which has approximately U-shape. They are filled with ballast material, which is in 1 exemplary for a tub under reference number 8th is illustrated. The weight of this ballast material 8th anchors the arrangement on the roof 4 ,

The edge areas of the tubs 6 form several camps 10 by acting as spring elements 11 are executed. Every camp 10 is made of two spring elements 11 neighboring tubs 6 educated. Camps 10 make up together with hook elements 12 of the second part 5 several connection mechanisms between the first part 3 and the second part 5 the carrying device 2 ,

The hook head 16 is formed in the present embodiment by a U-profile section whose base from the screw 14 is interspersed and whose legs are directed upwards.

The head of the screw 14 is at the top of the base of a horizontal U-beam 18 supported. The bottom 19 this U-carrier 18 forms a support surface, which against the upper outside of the camp 10 is supported.

An alternative embodiment of the hook element is in 10 shown. Here the screw extends 14 not by the wearer 18 but is on a holding element 35 attached, which in turn on the carrier 18 is mounted. This solution has the advantage that in the carrier 18 No holes need to be drilled and that the positions of the hook elements 12 along the carrier 18 can be chosen freely.

In the execution after 10 it is the holding element 35 around a profile section, which has a stiff, lateral arm 36 owns, over one of the arms of the wearer 18 laid and adapted to its shape. The arm 36 However, z. B. also be configured as a spring arm, which is the carrier 18 resiliently overlaps.

When assembling the assembly, the first part becomes first 3 the carrying device 2 on the roof 4 assembled. In addition, the second part 5 the carrying device 2 prefabricated, with the screws 14 and the hook heads 16 already assembled. During final assembly then the hook heads 16 under deformation of the spring elements 11 in the camps 10 snapped, so that in 1 shown situation arises where the hook elements 12 between the spring elements 11 every camp 10 are introduced. Now the screws can 14 be attracted, thereby increasing the distance between the hook heads 16 and the bottom 19 of the U-carrier 18 reduced. The spring elements 11 own, as in 1 shown at their top ends against the screws 14 bent ends, against the inside of the hook heads 16 when tightening the screws 14 come to lie and so a strong connection between the first part 3 and the second part 5 form.

Because the tubs 6 long profiles are whose length is the width of several solar modules 1 exceeds the camps 10 long slots, the side of the spring elements 11 are limited. In each of the camps 10 Thus, several hook elements 12 anchored, and the positions of the U-beams 18 can according to the positions of the solar modules 1 be chosen freely.

Every U-carrier 18 is, seen from above, between two adjacent solar modules 1 arranged and carries at least two support brackets 20 . 21 , Are the solar modules 1 , as in 1 shown to mount in an inclined position, so one of the support bracket, in the present example, the lower support bracket 20 , directly on the U-beam 18 be attached while the other support bracket, ie the upper support bracket 21 , via vertical beams 22 spaced from the U-beam 18 is mounted.
