The component can be, for example, the support, the solar module, or another solar module, to name just a few. According to one embodiment, the term "fixing" in this context, and generally herein, means fixing in at least one direction, unless otherwise specified.

[0050] According to one embodiment, the stop element and the base element can be plugged into one another to create a plug connection between the stop element and the base element.

[0061] Regarding the numbering of the surfaces (for example, the surfaces or the contact surfaces), it should be noted that the numbering used herein merely corresponds to the order in which the respective surfaces are mentioned and does not impose any further restrictions. Therefore, the numbering may be modified for certain combinations of features to reflect the order in which the corresponding features are mentioned. Such a change in numbering does not affect the scope of disclosure and is therefore within the scope of the present application.

[0062] Embodiments of the items disclosed herein can achieve higher system performance through improved surface utilization. Maintenance costs resulting from soiling and shading, particularly in cases of competing use with green roofs, but also from the growth of windblown seeds, etc., can be reduced through the improved surface utilization according to embodiments of the items disclosed herein. In particular, a plate-shaped design of a base element can reduce the spacing between solar modules compared to conventional solutions. According to some embodiments of the items disclosed herein, an attractive appearance of the systems can be achieved through smooth and flatly aligned module surfaces.According to embodiments of the items disclosed herein, the substructure of a solar power system, in particular the support devices and mounting systems, can be manufactured even in small quantities and essentially without significant investment costs such as mold making, etc. According to embodiments of the items disclosed herein, many standard components, standard semi-finished products, and standard raw materials can be used. Furthermore, little energy is required for the manufacture of the substructure. According to one embodiment, the solar modules are mounted vertically, i.e., the modules are oriented with their greater longitudinal extent in the direction of the slope. According to one embodiment, the modules are fastened in the area with the highest static load-bearing capacity (edge ​​insertion approximately 1 / 4 of the module length). According to another embodiment, standard rectangular steel tubes are used as supports along the longitudinal sides of the modules.This results in a minimal rail length to utilize an optimal mounting point. According to one embodiment, telescopic round tubes are used as supports. According to another embodiment, a roof fill is used as ballast for the solar array across its entire surface. According to yet another embodiment, panels or trays, particularly made of fiber cement, are installed to support the ballast. According to one embodiment, the panels or trays are placed on a base for the supports, for example, linear base brackets. The substructure according to embodiments of the items disclosed herein allows for the accommodation of irregularities in the existing substrate (for example, funnel-shaped drainage of the roof surface, constructed on-site, for instance, with insulation material).Due to the good height adjustability according to embodiments of the objects disclosed herein, a large degree of relocatability of supports and base angles is possible in order to bypass or build over roof structures (for example, vents).

[0063] A holding device according to embodiments of the items disclosed herein can have the following advantages: Tensile forces (wind suction) are transferred from the solar module to the substructure by means of the additional stop element, which, according to one embodiment, acts as a pressure plate, and the first stop surface. According to one embodiment, the additional stop element consists of a flat plate which is snapped into retaining lugs of a base element. According to one embodiment, the solar modules rest on the stop element, with compressive forces from the solar module being transferred, at least partially, via the stop element to the substructure. Fixing elements can facilitate the assembly of the holding device. According to one embodiment, the holding device or the base element is mounted laterally next to the support, with each module resting laterally flush above the support, according to another embodiment.According to one embodiment, the holding device has a fixing element (for example, a bore for a fastener such as a screw) that prevents the holding device from sliding along the support. According to another embodiment, the stop element has tabs that, bent out of the plane of the plate, prevent the solar module from sliding away from the holding device and parallel to it. According to a further embodiment, after the additional stop element has been mounted, a locking pin can be inserted to prevent the additional stop element from slipping out of the retaining lugs.

[0064] According to one embodiment, an edge holder comprises two parts. A first part is a base element (e.g., an edge plate) with a chamfer on its upper surface to counteract tensile forces on the module, and tabs or a chamfer on its lower surface to transfer the tensile force into the support. A second part is a stop element (e.g., a support plate) to prevent the solar module from sliding away from the edge holder or parallel to it. According to one embodiment, the stop element has tabs connected to the base element that prevent the base element from sliding away from the support. According to another embodiment, the base element has a fixing element (e.g., a hole for a fastener such as a screw) that prevents the holding device from sliding along the support.

[0065] The supports for the beams consist of two interlocking round tubes, which are positively connected to each other using a conventional pipe press, so that the supports can transmit tensile and compressive forces in the longitudinal direction.

[0066] According to another embodiment, fiber cement elements (for example, fiber cement sheets or corrugated fiber cement sheets) are used for ballast (bulk material). According to one embodiment, the fiber cement elements are placed without constraint on a support (for example, linear support angles), wherein according to a

[0067] In this embodiment, the gap between a substrate (e.g., a roof surface) and the underside of the fiber cement elements is dimensioned such that, during the planned ballast distribution, this gap disappears in the center of the elements. This means that the fiber cement element, when loaded with ballast material, sags down to the substrate in the middle. When the fiber cement panel is walked on (e.g., during installation), a significant portion of the load is transferred directly to the substrate, thus protecting the fiber cement element from damage due to overloading.

[0068] Holding devices according to embodiments of the articles disclosed herein are suitable for use on flat roof substructures as well as on rooftop installations (on pitched roofs). Likewise, holding devices according to embodiments of the articles disclosed herein are suitable for any other substrate and also for wall mounting. According to one embodiment, the edge holders can have the advantage of being visually appealing and completing the installation without protruding supports.

[0069] Exemplary embodiments of the items disclosed herein are described below, with reference, for example, to a method for mounting a solar module, a holding device, a mounting system, a support device, and a solar power plant. It should be emphasized that, of course, any combination of features of different aspects, embodiments, and examples is possible. In particular, some embodiments are described with reference to a method, while other embodiments are described with reference to a device (for example, a holding device, a mounting system, a support device, and / or a solar power plant).However, the person skilled in the art will understand from the foregoing and following description, the claims, and the drawings that, unless otherwise stated, features of different aspects, embodiments, and examples can be combined, and such combinations of features are to be considered disclosed by this application. For example, even a feature relating to a method can be combined with a feature relating to a device, and vice versa.

[0088] Furthermore, the base element 118 has a fixing element 140, for example in the form of a slot (for example as in Fig. 1 (shown), which is connected to a corresponding locking element of the stop element 120 (in Fig. 3 (not shown) can be locked in place.

[0089] Fig. 4 shows a view of the stop element 120 from Fig. 1 from above.

[0090] According to one embodiment, the base element 118 and the stop element 120 can be plugged into one another. For this purpose, the stop element 120 can, for example, have an opening 142 through which the base element 118 can be inserted into a first position 144, which is in Fig. 4 The base element 118, shown with a dashed line, can be inserted through the stop element 120. By subsequently moving the base element 118 laterally into a second position, shown at 146, a fixing element 148 of the stop element 120 can engage with the fixing element 140 of the base element to fix the base element 118 and the stop element 120 relative to each other. For example, the fixing element 148 of the stop element can be formed by a tab that can be inserted through the corresponding slot (fixing element 140) of the base element 118. According to one embodiment, the tab can be plastically deformable to secure the second position 146 of the base element 118.

[0091] According to one embodiment, one of the elements described herein, for example the stop element 120, has a plastically deformable element 150, for example a bendable tab, for example as in Fig. 4 Illustrated by example at 150.

[0092] As above with reference to Fig. 1 As described, the plastically deformable elements 150 can be used to produce the surface profile 132 or the fixing element 130. According to one embodiment, several plastically deformable elements 150 are provided to produce a suitable element (e.g., a fixing element 130 or a surface profile 132) depending on the specific application (e.g., depending on the solar module 102, 104 used or the support 106 used). According to one embodiment, the corresponding deformation of the plastically deformable element 150 can take place during the assembly of the solar module at the installation site of the solar power system.

[0093] Fig. 5 The further stop element 128 is shown. Fig. 1 in a top view.

[0094] According to one embodiment, the further stop element 128 has an opening 152 for each locking element 136 of the base element 118, through which the locking element 136 can be inserted so that, by subsequent displacement of the further stop element 128 relative to the base element 118, an adjacent part 154 of the further stop element 128 is inserted into the undercut 138 of the base element (see Fig. 3 ) and thus lock the further stop element 128 and the base element 118 together. To fix this position, a locking element, for example a locking pin, a locking plastic, etc., can be inserted into the exposed part of the opening 152. In this way, tensile forces on the further stop element 128 can be reliably transferred to the base element 118.

[0095] Fig. 6 shows a rim holder 156 according to embodiments of the objects disclosed herein.

[0096] According to one embodiment, the rim holder also has a base element 158 ​​and a stop element 160. A first stop surface 162 of the rim holder 156 is formed, according to one embodiment, by the base element 158, for example by a bent portion of a plate-shaped base element, for example as shown in Fig. 6 As shown. According to one embodiment, a second stop surface 164 of the rim holder 156 is formed by the stop element 160 of the rim holder. According to one embodiment, the stop element 160 of the rim holder is inserted through at least one opening 166 in the base element 158 ​​of the rim holder.

[0097] According to one embodiment, a second support 206 is positioned on the first stop surface 162. A fixing element can be provided to fix the position of the second support 206, as described in relation to Fig. 1 was described (in Fig. 6 (not shown). According to one embodiment, a solar module, for example the solar module 102, is positioned on the second stop surface 164. It is understood that the edge holder 156 and the holding device 100 are thus made of Fig. 1 Together, the solar module 102 is fixed from two sides. According to one embodiment, both the solar module 102 and the second support 206 are located opposite the same side (i.e., the same surface 170) of the base element 158. Thus, with a suitable number of edge supports 156 and holding devices 100, areas of any size can be covered with solar modules without large gaps.

[0098] Fig. 7 shows the base element 158 ​​of the edge holder 156. Fig. 6 Viewed from line VII-VII.

[0099] According to one embodiment, for example, two openings 166 may be provided, for example as in Fig. 7 depicted.

[0100] Fig. 8 shows a top view of the stop element 160 of the edge holder 156. Fig. 6 .

[0101] According to one embodiment, the stop element 160 of the edge holder 156 has projections 168 which are connected by the openings 166 of the base element (compare Fig. 7 ) are insertable through to fix the stop element 160 of the edge holder 156 to the base element 158. According to one embodiment, the projections 168 can be plastically deformable so that, by deforming (e.g., bending or twisting) the projections 168, the stop element 160 is secured in this inserted position in the base element 158. According to another embodiment, the stop element 160 can have one or more plastically deformable elements 150, as described by way of example with reference to Fig. 4 were described and how they can be used, for example, to fix the second support 206 and / or the associated solar module 102.

[0102] Fig. 9 A further holding device 200 according to embodiments of the objects disclosed herein is shown in a sectional view.

[0103] According to one embodiment, in the holding device 200 the fourth stop surface 122, which is opposite the first stop surface 112, is formed by the base element 118, for example as in Fig. 9 as shown. In other words, in this embodiment the fourth stop surface 122 is arranged at a distance 172 from the stop element 120.

[0104] Fig. 10 A side view shows a further holding device 300 according to embodiments of the items disclosed herein.

[0105] According to one embodiment, the stop element 120 has projections 174 which (for example, at their ends) form the fourth stop surface 122. For example, the projections 174 can be formed by a portion of a plate-shaped stop element 120 which is angled relative to a plate plane, for example, as in Fig. 10 shown. In this way, a distance 176 between the solar module 102 and the fourth stop surface 122 (or a top surface of the support 106) is defined via the projections 174.

[0106] Fig. 10 further shows locking elements 136, such as those used with reference to Fig. 3 as described above. According to one embodiment, in an inserted state in which the further stop element 128 is inserted into the undercut 138, a locking element 180 is introduced into the exposed part 178 of the opening 152, for example as shown in Fig. 10 depicted.

[0107] The design of the locking mechanism with the locking elements 136 of the base element 118 and the further stop element 128 allows for a high degree of mechanical strength to be achieved in a simple manner, particularly against tensile forces acting on the solar modules in a direction away from the second stop surface 114. Such tensile forces occur, for example, when wind flows over the solar modules. The forces acting on the fifth and sixth stop surfaces in this process (see, for example, [reference]) Fig. 1 ) are transferred via the first stop surface 112 to the carrier 106.

[0108] Fig. 11 shows part of a solar power system 182 with a first solar module 102 and a second solar module 202.

[0109] According to one embodiment, the solar modules 102 and 202 are arranged at an angle to a horizontal direction 183, with the first solar module 102 positioned below the second solar module 202 in a downslope direction 184. Furthermore, the first solar module 102 is arranged in an overlap area with the second solar module 202 above the second solar module 202, for example as shown in Fig. 11 The first solar module 102 thus forms a barrier 186 above the surface 185 of the solar module 202, which, for example, prevents snow located on the solar modules 102, 202 from sliding off. The tilt angle of the solar modules is typically 15 degrees (for example, between 10 degrees and 20 degrees).

[0110] Fig. 12 shows part of another solar power system with a support device according to embodiments of the items disclosed herein.

[0111] According to one embodiment, the solar system 282 has a support device for at least one solar module (solar module in Fig. 12 (not shown). The beam 106 is supported against a substrate 191 (for example, a flat roof, a pitched roof, or the ground) by means of supports 190. According to one embodiment, the supports 190 are telescopic supports whose height is continuously or incrementally adjustable. Furthermore, the beam 106 is attached to a fiber cement board 192 via the supports 190 by placing the fiber cement board 192 on a base 193 of the supports 190. The fiber cement board is designed to receive a bulk material, in Fig. 12 An example is shown at 195. The fiber cement board can have a recess 194, for example as shown in Fig. 12 As shown. According to another embodiment, the fiber cement board can be a flat board (or a corrugated board) on which the bulk material 195, for example gravel, can be deposited. Due to the weight of the bulk material and the mechanical stability of the fiber cement board, the solar system can also withstand high wind forces.
