[0002] Bracket for holding a photovoltaic module on a

[0003] Sheet metal roof and assembly template for mounting the bracket

[0004] Technical area

[0005] The invention relates to a bracket for holding one or more photovoltaic modules on a sheet metal roof and an assembly jig for mounting the bracket.

[0006] A sheet metal roof is a generally weatherproof, roof-shaped covering made of sheet metal for a building. The sheet metal roof is preferably corrugated, with the waves often having a trapezoidal shape. In the following, the term "sheet metal roof" refers to a roof covering—with or without a slope—made of metal, such as steel, copper, aluminum, or zinc. A sheet metal roof can have one or more flat metal parts that form the roof covering.

[0007] State of the art

[0008] From the printed document DE 20 2015 102 941 U1 a device for fastening photovoltaic modules to a trapezoidal sheet metal roof is known. The fastening device comprises a lower part with a fastening plate which is screwed to one of the two sloping sides of a trapezoidal sheet metal. The fastening device also comprises an upper part, wherein the upper part and the lower part each have a C-shaped section, and wherein the two sections interlock such that the upper part can be rotated relative to the lower part. To prevent the upper part from slipping relative to the lower part, the upper part and the lower part are screwed together in the region of the C-shaped section by means of a screw. The upper part is rail-shaped at the top. A clamping mechanism is slidably held therein.The clamping mechanism comprises a component that can be moved within the rail, a clamping plate, and a screw with which the photovoltaic module can be clamped between the clamping plate and the rail. The fastening device consists of a relatively large number of individual parts. This makes logistics complex and can lead to errors during installation. Because the upper part can be rotated relative to the lower part and the clamping mechanism can slip, the fitter on the roof not only has to hold the screws and tools with which the fastening device is to be attached to the sheet metal roof, but also has to correctly position the movable fastening device at the same time. This requires manual dexterity and makes installation on the roof complex and time-consuming.

[0009] Description of the invention

[0010] An object of the invention is to provide a bracket for holding a photovoltaic module on a sheet metal roof, which requires few components and can be easily attached to the sheet metal roof.

[0011] Advantageously, the bracket and the photovoltaic modules can be assembled without special tools. A further advantage of the bracket according to the invention is that it requires only a few different components, which significantly simplifies component storage. The bracket according to the invention is also stackable and can be stored in a space-saving manner.

[0012] In addition, a photovoltaic system can be installed with the help of the bracket according to the invention in just a few steps, which reduces installation costs, helps to avoid installation errors and ensures a consistently high quality during installation.

[0013] Another advantage is that the photovoltaic modules do not slip due to the design of the holder and can be positioned quickly and precisely with the help of the holder.

[0014] The bracket according to the invention can be rotated by 180° about the vertical axis, so that it can be fastened to the roof in a first position (first mounting position) or in a second position (rotated by 180° = second mounting position). The position of the photovoltaic module to be fastened with the bracket does not change as a result. This has the following advantage. It is assumed that the bracket is to be fastened to the roof in the first mounting position. However, if there is already a roof screw where the bracket is to be fastened to the roof, with which the roof is fastened to the substructure, the bracket cannot be fastened in the first mounting position. In this case, the bracket is now rotated by 180° as mentioned above and thus brought into the second mounting position.While this changes the mounting locations where the bracket can be attached to the roof, the position of the photovoltaic module to be secured with the bracket remains unchanged. This way, the bracket can still be attached to the roof; the location of the roof screw is therefore irrelevant with regard to the mounting of the bracket.

[0015] The object is achieved by a holder for holding a photovoltaic module on a sheet metal roof with the features specified in patent claim 1.

[0016] The holder according to the invention for holding a photovoltaic module on a sheet metal roof has a base, wherein the base comprises a first fastening point and a second fastening point. The fastening points are designed such that the base can be fastened there on the sheet metal roof. The base also comprises a stationary stop for the photovoltaic module that is inseparably connected to the base. The stop is provided to define the position of the photovoltaic module. In addition, the holder has a retaining bracket, wherein the photovoltaic module can be fastened between the base and the retaining bracket in a form-fitting and / or force-fitting manner.

[0017] Advantageous further developments of the invention result from the features specified in the dependent patent claims.

[0018] In one embodiment of the holder according to the invention, a clamping means is provided which is designed such that the photovoltaic module can be clamped between the base and the retaining bracket.

[0019] In a further embodiment of the holder according to the invention, the base has a sleeve-shaped projection with a thread. This has the advantage that a screw (if the thread is internal) or a nut (if the thread is external) can be attached to it particularly easily.

[0020] In an additional embodiment of the bracket according to the invention, the thread is an internal thread. This ensures that the screw with which the PV module is attached to the bracket can be easily

[0021] In another embodiment of the holder according to the invention, the stop is part of the sleeve-shaped projection.

[0022] It is particularly advantageous to design the sleeve-shaped projection with a circular cross-section and thus the stop with a circular or cylindrical shape. In this case, the base does not need to be precisely aligned in the x and y directions because the circular projection ensures that it is at the same distance from the vertical axis in every rotational position and thus always defines the correct position for the PV module to be attached in every rotational position. Furthermore, the holder according to the invention can be provided with the sleeve-shaped projection located outside the center of the base.

[0023] In a further development of the inventive bracket, two screws are provided, with which the base can be screwed onto the metal roof. A seal can be provided for each screw to seal the screw hole.

[0024] In another embodiment of the holder according to the invention, a metal tab is provided that can be plugged onto the base and is designed to accommodate an electronic assembly. The metal tab can be used to secure an inverter and / or a cable, for example.

[0025] In an additional development of the holder according to the invention, the base has a through-hole arranged and shaped in the base to accommodate the sleeve-shaped projection of another base of identical construction. This has the advantage that the bases can be stored in a particularly space-saving manner. For example, significantly more bases can be accommodated in one box. This is also advantageous during installation, because the fitter can carry a particularly large number of bases in one box, even on the roof.

[0026] In a further development of the inventive mount, the base has an additional stop to define the position of another photovoltaic module. In the inventive mount, the stop and the additional stop can define the distance between the photovoltaic module and the other photovoltaic module. The installer does not need to measure anything and can rely on the fact that neighboring photovoltaic modules are always at the correct distance from one another.

[0027] In one embodiment of the holder according to the invention, the retaining bracket has a first leg and a second leg. The first leg is provided in connection with the base to firmly hold the photovoltaic module, and the second leg is provided in connection with the base to firmly hold the additional photovoltaic module.

[0028] In an additional embodiment of the holder according to the invention, the base is an injection-molded component.

[0029] Advantageously, the base is made of die-cast aluminum.

[0030] Furthermore, an assembly jig for mounting the holder according to the invention is proposed, wherein the holder can be fastened precisely and even more easily to the sheet metal roof with the aid of the assembly jig. The assembly jig has a first receptacle for the base of the holder and a second receptacle for a further base of a further holder identical in construction to the holder. The first receptacle and the second receptacle are spaced apart from one another by a distance which defines the mounting position of the base relative to the further base. It can be provided that the assembly jig is designed such that the distance is adjustable. This means that the assembly aid can be adapted to photovoltaic modules of different sizes.

[0031] Finally, a photovoltaic system is proposed that features multiple versions of the mounting brackets described above. The photovoltaic system also includes photovoltaic modules that are mounted on a metal roof using the mounting brackets.

[0057] Ways to implement the invention

[0058] Figures 1 to 6 show various views of a first possible embodiment of a holder 10. The holder 10 is provided for fastening one or more photovoltaic modules 30 (see Figures 19 to 22) to a sheet metal roof 20. The holder 10 comprises a base 1 which has a first fastening point 1.5 at its front end and a second fastening point 1.6 at its rear end. The two fastening points 1.5 and 1.6 are designed such that the base 1 can be connected there to the sheet metal roof 20. For the connection, two screws 5 and 6 are preferably used which can be inserted through corresponding holes 1.10 and 1.11 (see Figure 12) provided in the region of the fastening points 1.5 and 1.6. The screws can be self-tapping screws. Other fastening means, such as rivets, can also be used instead of screws.

[0059] The base 1 (see also Figures 10 to 12) can have a first web 1.2 on one of its longitudinal sides and a second web 1.3 on its other longitudinal side. The two webs 1.2 and 1.3 can serve as a support surface for the photovoltaic module 30 (see Figure 22).

[0060] Base 1 has a stop 1.1, which serves to attach the photovoltaic module 30 to it. The stop 1.1 is fixed to the base 1 and is inseparably connected to the base 1. This has the advantage, among other things, that the position of the stop 1.1 is always precisely defined in relation to the two fastening points 1.5 and 1.6. Once base 1 is attached to the metal roof, the position of the photovoltaic module 30 is also determined. The photovoltaic module 30 now only needs to be attached to the stop 1.1 and clamped in place.

[0061] To securely clamp the photovoltaic module 30, the holder 10 has a retaining bracket 4, which can be connected to the base 1, for example, via a screw 3. In the mounted state (see Figure 22), the photovoltaic module 30 rests on the webs 1.2 and 1.3 and against the stop 1.1. The retaining bracket 4 presses on the photovoltaic module 30 from above, thereby fixing its position. The clamping force with which the photovoltaic module 30 is clamped between the retaining bracket 4 and the webs 1.2 and 1.3 can be adjusted using the screw 3.

[0062] In a preferred embodiment, the retaining bracket 1 has a first leg 4.3 and a second leg 4.4. The first leg 4.3 is provided in conjunction with the base 1 to firmly hold a first photovoltaic module 30. The second leg 4.4 is provided in conjunction with the base 1 to firmly hold a further photovoltaic module 30. The base 1 can have a further stop 1.9. The further stop 1.9 serves to attach a further photovoltaic module 30 to the base 1. The further stop 1.9 is also fixed to the base 1 and inseparably connected to the base 1. This has the advantage, among other things, that the position of the further stop 1.9 in relation to the two fastening points 1.5 and 1.6 is always precisely defined.

[0063] Normally, only one of the two stops 1.1 or 1.9 is required. Providing two stops 1.1 and 1.9 is particularly advantageous if the bracket 10 is to be used in the first mounting position (0°; Figure 22) and the second mounting position (rotated 180° around the vertical axis VA; Figure 23). In this case, one stop 1.1 or 1.9 is available for both the first and second mounting positions.

[0064] Since the PV module 30 is typically mounted on the roof 20 at a certain incline, usually parallel to the roof pitch, there are two brackets 10 located higher and two lower on which the PV module 30 rests (see Figure 20). The easiest way to mount the PV module 30 is to allow the lower edge of the PV module 30 to rest against the upper stop of each of the two lower brackets 10.

[0065] The bracket 10 has a vertical axis VA located at the center of the sleeve 1.8. The two stops 1.1 and 1.9 are arranged symmetrically to the vertical axis VA. If the bracket 10 is rotated 180° around the vertical axis VA, the distances between the two stops 1.1 and 1.9 and the vertical axis VA do not change. Since the two stops 1.1 and 1.9 define the position of the photovoltaic module(s) 30 to be attached, the position of the photovoltaic module(s) 30 also remains unchanged. The bracket 10 can therefore be attached to the roof 20 in a first position (first mounting position) or in a second position (rotated 180° = second mounting position) without this having any influence on the position of the PV module 30 aligned with the stop 1.1. The same applies mutatis mutandis to the PV module 30 aligned with the stop 1.9. This has the following advantage.In the following, it is assumed that the bracket 10 is to be fastened to the roof 20 in the first mounting position. However, if there is already a roof screw 21 where the bracket 10 is to be fastened to the roof 20 (see Figure 22), the bracket 10 cannot be fastened in the first mounting position. In this case, the bracket 10 is now rotated by 180°, as mentioned above, and thus brought into the second mounting position (see Figure 23). Although this changes the locations on the roof where the bracket 10 is fastened, the position of the photovoltaic module 30 to be fastened with the bracket 10 remains unchanged (Figures 22 and 23). In this way, the bracket 10 can still be fastened to the roof 20. The bracket 10 can therefore be fastened to the roof 20 regardless of where the roof screw 21 is located. Where the roof screw 21 is located therefore does not play a role in terms of the attachment of the bracket 10.This allows for the roof screw 21 to be avoided, which would otherwise be located under one of the fastening points 1.5 or 1.6. Since the assembly jig is aligned with the stops 1.1 / 1.9, the installer can align the base on the roof 20 during installation to ensure it fits.

[0066] The two webs 1.1 and 1.9 can be arranged on the base 1 in such a way that they specify the distance xl that should exist between two adjacent photovoltaic modules 30.

[0067] In one embodiment of the holder 10, not only the two stops 1.1 and 1.9 have the distance xl, but also the retaining bracket 4 has two stops 4.1 and 4.2, which have the distance xl from each other.

[0068] The base 1 can be designed symmetrically to the longitudinal axis LA.

[0069] The base 1 may comprise a sleeve 1.8 with a thread.

[0070] The sleeve 1.8 can be provided with an internal thread, as shown in the figures. However, it is also possible to attach an external thread to the sleeve 1.8. In this case, the sleeve 1.8 serves as a screw. The retaining bracket 4 is then attached to the base 1 with a nut (not shown in the figures) instead of the screw 3.

[0071] The sleeve 1.8 and the two stops 1.1 and 1.9 are preferably arranged asymmetrically to the central axis MA. The resulting advantage is explained below.

[0072] The sheet metal roof 20 is usually screwed to the roof substructure with screws 21. To seal the screw hole, a plate-shaped seal can be provided between the head of the screw 21 and the sheet metal roof 20. The head of the screw 21 and the seal have a certain height, so that they are not flush with the sheet metal roof, but protrude above it (see Figures 22 and 23). The base 1 has a recess 1.12 on its underside. The recess 1.12 has a defined width x2 and a defined height zl. The width x2 and height zl are selected such that the base 1 can also be placed directly above the screw 21, if necessary. If the local situation requires it, the base 1 can be placed in various positions above the screw 21. In the event that the photovoltaic module 30 has to be placed above the screw 21 in such a way that the fastening point 1.6 of the base 1 would rest on the screw 21, the base can be rotated 180° and then fixed to the sheet metal roof (Figure 23). With the base 1 designed in this way, it is ensured that the photovoltaic module 30 can be positioned in any conceivable position on the sheet metal roof 20 and secured with the bracket 10.

[0073] In addition, the base 10 can be provided with a tab 1.7. The tab 1.7 can be used, for example, to attach a cable tie. The cable tie (not shown in the figures) can be used, for example, to secure an electrical cable.

[0074] Seals 7 and 8 may be provided on base 1.

[0075] Seals 7 and 8 can be molded onto base 1 or inserted into holes 1.10 and 1.11. Seals 7 and 8 serve to seal screws 5 and 6 and the metal roof 20. This ensures that no water penetrates through the screw holes into or under the metal roof 20.

[0076] In one embodiment, the base 10 is manufactured as a stamped sheet metal component.

[0077] In a further embodiment, the holder 10 has a sheet metal tab 2. It can be used to attach an electronic assembly, such as an inverter. The sheet metal tab 2 can have a snap connection for this purpose. The assembly is then simply placed onto the sheet metal tab 2 and snaps into place. The sheet metal tab 2 can be manufactured as a stamped sheet metal part.

[0078] The base 1 is preferably designed so that it can be stacked in a particularly space-saving manner. A stack formed from two bases 1 is shown by way of example in various views in Figures 7 to 9. The base 1 can have a hole 1.4 in the front half. The diameter or shape of this hole is selected so that the sleeve 1.8 of a second, identically constructed base 1 can be pushed through the hole 1.4. By placing two adjacent bases 1 on top of each other rotated by 180° to each other, the bases 1 can be stacked in a particularly space-saving manner. In addition, they are positively connected to one another and thus form a relatively stable stack. In this way, any number of bases 1 can be stacked on top of one another.

[0079] Figures 13 to 18 show various views of a second possible embodiment of the base 101. The holder 10 can be equipped with the base 1 or the base 101 in order to attach one or more photovoltaic modules 30 to the sheet metal roof 20.

[0080] Like the base 1, the base 101 also has a first fastening point 1.5 at its front end and a second fastening point 1.6 at its rear end. The two fastening points 1.5 and 1.6 are designed such that the base 101 can be connected to the sheet metal roof 20 at these points. Here, too, two screws 5 and 6 are preferably used for the connection, which can be inserted through corresponding holes 1.10 and 1.11 (see Figure 14) provided in the area of ​​the fastening points 1.5 and 1.6. The screws 5 and 6 can be self-tapping screws. Other fastening means, such as rivets, can be used instead of screws. The base 101 is shorter than the base 1. This means that less material is required to manufacture it, so that it can be manufactured even more cost-effectively than the base 1.

[0081] Seals 7 and 8 may also be provided on the base 101. The seals 7 and 8 may be molded onto the base 101 or inserted into the holes 1.10 and 1.11.

[0082] Like the base 1, the base 101 can also include a sleeve 1.8 with a thread. In the embodiment shown in Figures 13 to 8, the sleeve 1.8 and the two stops 1.1 and 1.9 are arranged symmetrically to the central axis MA. However, this is not mandatory.

[0083] In order to mount a photovoltaic system on the sheet metal roof 20, a plurality of photovoltaic modules 30 are generally arranged in a matrix on the sheet metal roof 20. An example of a photovoltaic system having eight photovoltaic modules 30 is shown in Figure 19. In order to enable the bases 1 and 101 required for mounting the photovoltaic modules 30 to be arranged simply, quickly and precisely in a row and equidistantly, an assembly jig 200 shown in Figures 24 to 26 can be used. The assembly jig 200 has a first receptacle 201 at one end and a second receptacle 202 at its other end. The two receptacles 201 and 202 are designed such that they can each accommodate a base 1 or 101.

[0084] The assembly jig 200 is preferably designed such that the distance x3 between the two receptacles 201 and 202 is adjustable. For this purpose, the assembly jig 200 may have a locking device 206 and a scale 204 that indicates the distance x3 between the two receptacles 201 and 202.

[0085] In order to mount the bases 1 at the correct distance x3, the desired distance x3 is initially set once on the mounting jig 200. The holder 202 of the mounting jig 200 is then placed on an already mounted base 1 and the base still to be mounted is pushed into the holder 201. The mounting jig 200 is then aligned, for example, along an edge on the sheet metal roof 20. The base 1 or 101 to be mounted is now already in the correct position. It is also held in the correct position by the mounting jig 200 and can be fastened to the sheet metal roof 20. To mount another base 1 or 101, the procedure just described is repeated. The preceding description of the embodiments according to the present invention is for illustrative purposes only. Various changes and modifications are possible within the scope of the invention.For example, the various components of the bracket 10 shown in Figures 1 to 18 can also be combined with one another in a manner different from that shown in the figures. Furthermore, the brackets 10 can also be attached to a metal roof that has a different shape than the metal roof 20 shown in the figures.
