Also, this fixation is not suitable for uneven foundations
[0003] Furthermore, it should be noted that the adhesives used are exposed to external factors such as weather elements and UV radiation, which can damage the adhesive over time and thus further weaken the composite
[0004] Also note that in the case of solar cells mounted directly on the roof membrane, for example by gluing, the solar cells are highly exposed to mechanical loads, which can lead to damage to the solar cells

Embodiment Construction
[0040] figure 1 A schematic illustration shows a cross-section of a welded web element 100 , which is designed here as a welded web 100 , comprising at least one base plate element 110 and two latching elements 120 , 130 , which The element is arranged eccentrically in the cross-section of the welded web element 100 and on the edge, that is to say on one side (in figure 1 middle is on the right).
[0041] The two latching elements 120 , 130 are identical with respect to their respective cross sections and each have a first section 122 , 132 on the base plate element side, which has a substantially rectangular cross-sectional shape. And it protrudes roundedly, ie with roundings 123 , 133 , from the upper side of the base plate element 110 of the solder connection plate element 100 . On the head side of the latching elements 120 , 130 there is in each case an integral molding 125 , 135 with an essentially oval cross-section, which respectively forms a second section 125 , 135 ...

The present invention relates to a welding-lug element (100, 100', 1100, 2100, 3100, 4100), in particular a welding-lug element (100, 100', 1100, 2100, 3100, 4100) for a fastening system (10) for a photovoltaic installation, having at least one baseplate element (110, 1110, 2110, 3110, 4110) and at least one latching element (120, 130, 1120, 2120, 3120, 4120), wherein the latching element (120, 130, 1120, 2120, 3120, 4120) has at least one first portion (122, 132, 1122, 2122, 3122, 4122) and at least one second portion (125, 135, 1125, 2125, 3125, 4125), wherein the first portion (122, 132, 1122, 2122, 3122, 4122) is arranged on the baseplate element, and wherein the first portion (122, 132, 1122, 2122, 3122, 4122) has a first width in relation to the cross section, wherein the second portion (125, 135, 1125, 2125, 3125, 4125) is arranged at the head of the latching element (120, 130, 1120, 2120, 3120, 4120), and wherein the second portion (125, 135, 1125, 2125, 3125, 4125) has a second width in relation to the cross section, wherein the second width has a greater extent than the first width. The present invention also relates to a carrier element (200, 200', 1200, 2200, 3200, 4200) for a fastening system (10) of a photovoltaic installation, to the fastening system (10) for the photovoltaic installation, and to a method of installing a fastening system (10) for the photovoltaic installation.
Description
technical field [0001] The invention relates to a welded web element for a fixing system of a photovoltaic device, a support element for a fixing system of a photovoltaic device, a fixing system for a photovoltaic device and a method for mounting a photovoltaic device method of fixing the system. Background technique [0002] It is known in the art to mount solar cells on roofing membranes by means of adhesives. However, this type of fastening of the solar cells has the disadvantage that the solar cells can separate from the roofing membrane, in particular due to mechanical stress, and cavities form between them. Moisture that subsequently penetrates into these cavities has a particularly adverse effect on the composite of solar cells and roofing membrane, in particular by damaging the adhesive, and leads to further detachment of the solar cells from the roofing membrane. Also, this fixation is not suitable for uneven foundations. [0003] Furthermore, it should be noted ...
