Description

[0001] The invention relates to a bracket for attaching a photovoltaic module, as well as a kit with a bracket.

[0002] The mounting of photovoltaic modules on balconies or balcony railings is becoming increasingly important. Regular requirements include installation that leaves as little trace or damage as possible, coupled with a durable hold. There is a need to further improve the mounting method with regard to installation and safety.

[0003] The invention is based on the object of providing solutions to improve the fastening of photovoltaic modules. In particular, disadvantages of the prior art are to be avoided or reduced.

[0004] The invention is defined by the features specified in the independent claims. Preferred embodiments are specified in the subclaims, the description, and the drawings, each of which, individually or in combination, may represent an aspect of the invention.

[0005] In particular, the problem is solved by a bracket for attaching a photovoltaic module to a balcony railing. The bracket has a first section for resting on a balcony railing; a second section for attachment to a photovoltaic module, wherein the first section and the second section are at least partially fixedly connected to one another and extend at least partially transversely to one another; a third section to be arranged or arranged opposite the second section; and a securing member for attachment to the second section and / or the third section, the securing member being adjustable along the second and / or third section and providing a fourth section to be arranged or arranged opposite the first section.

[0006] In other words, for example, a bracket is proposed which has three essentially U-shaped holding areas (first, second, and third sections) for gripping a balcony railing. In particular, the bracket has a fourth holding area (securing part with fourth section) which can be adjustably arranged on one of the three holding areas or on one of the two U-legs, in particular so that the balcony railing can be positively received between all holding areas. The fourth holding area can be adjusted to different distances from the opposite holding area or from the U-web connecting the two U-legs (the securing part is adjustable along the second / third section). In particular, the holding areas or U-web and U-legs can be at least partially permanently connected to one another.

[0007] The holder leads to numerous advantages, which can be further enhanced by the embodiments or optional features disclosed herein.

[0008] The bracket can be flexibly adapted to different sizes and shapes of balcony railings thanks to the adjustability of the fourth section.

[0009] The bracket can be securely attached to a balcony railing by adjusting the safety part, in particular by adjusting the safety part as close as possible to the first section during installation.

[0010] By at least partially firmly connecting the first and second sections, a secure and durable connection is achieved. The first section resting on a balcony railing is at least partially secured against the second section, making the fastening more secure.

[0011] Thanks to the first, second and third sections, the bracket can be placed or hooked onto a balcony railing from above in order to achieve a form fit, thus making installation much easier and providing protection against falling.

[0012] A bracket is typically understood as a single- or multi-part fastening device designed to hold an object. A bracket can be used to attach a photovoltaic module to a balcony railing, in particular, to fix it permanently and non-destructively.

[0013] A photovoltaic module is also known as a PV module, solar module, solar panel, or solar array. The photovoltaic module can generate electrical energy from light or sunlight. The photovoltaic module usually has solar cells. The photovoltaic module typically has a frame, in particular in which the solar cells can be held and protected. For example, the solar cells are attached to a transparent plate, in particular a glass plate, and preferably in the frame. The frame can frame the plate. The frame is typically formed with metal or aluminum profiles. The frame is preferably rectangular.

[0014] The photovoltaic module is typically used as part of a balcony power plant. A balcony power plant, for example, comprises at least one photovoltaic module and an inverter connected to the photovoltaic module, and optionally a battery storage system connected to the photovoltaic module and the inverter. The bracket can be used or intended as part of a balcony power plant.

[0015] A balcony, for example, is a projecting part of a building that is accessible and is usually designed without a roof and / or without complete enclosure, at least in part. A balcony is usually spatially defined by a railing or balcony railing. The balcony railing can also be provided by a parapet.

[0016] The holder preferably has a plurality of sections. The sections are preferably understood to mean adjacent regions and / or parts. The sections typically differ in that they are formed substantially separately from one another, perform different functions, and / or are aligned differently. For example, a kink or a curve can distinguish two adjacent sections from one another. Sections can be formed integrally or monolithically with one another. Individual sections can be formed from a plurality of parts. In particular, the first section can be formed partly by a main part and partly by an adjustment part. Typically, at least one of the sections is adjustable relative to the other sections, and / or all sections can be fixed relative to one another, in particular selectively.

[0017] The first section is designed to rest on a balcony railing. For example, the underside of the first section, or the side facing the second and third sections, can rest on the balcony railing.

[0018] The second section is intended for attachment to a photovoltaic module. For example, the second section has a substantially flat rear side, which is intended for contact with the photovoltaic module. The second section can be connected to the photovoltaic module, in particular detachably, e.g., by screwing.

[0019] The first and second sections are preferably at least partially rigidly connected to one another. They are preferably formed monolithically. The second and first sections preferably extend transversely to one another, in particular perpendicular to one another. For example, the third section extends opposite the second section and is arranged, in particular, parallel to it.

[0020] The securing part in particular has or provides the fourth section. For example, the fourth section points to the first section and / or runs substantially parallel thereto, in particular so as to have one side facing the first section. The fourth section is preferably arranged opposite the first section. The securing part can be fastened, for example screwed, to the second section and / or the third section in particular in an adjustably manner. The securing part can be adjusted in the direction of extension or along the second and / or third section. In a simple case, the securing part can be provided by a screw connection or by a screwed component.

[0021] In principle, the holder can have passages for screw connections or the like. The passages mentioned here can be designed to accommodate the dimensions of screw connections mentioned here in a technically expedient manner. For example, a technically expediently designed passage for a screw connection is large enough to accommodate a thread and small enough to allow a screw head or nut of the screw connection to rest against it.

[0022] Preferably, the securing part has at least substantially a shape with two leg sides, preferably an L-shape. For example, the securing part can be a section of an L-profile and / or an originally flat semi-finished product bent into an L-shape, e.g., a metal material such as flat steel, or can be formed therefrom. A first of the two leg sides can provide the fourth section. A second of the two leg sides can be provided for contact with and attachment to the third section, in particular, can have a passage.

[0023] The securing part can have a passage for fastening. For example, the passage can be a hole, in particular a round hole. The passage can be square, for example, to form a positive connection with a carriage bolt. The passage can be provided on one of the two leg sides, in particular on the second leg side.

[0024] Each of the sections, in particular the third section, can have at least one passage, for example for fastening the securing part. The passage can be an elongated hole. The elongated hole can extend along the respective section, in particular the third section.

[0025] At least two of the first portion, the second portion, and the third portion, in particular the first, the second, and the third portion, may be formed integrally with each other to provide a / the main part.

[0026] The distance between the second section and the third section can be at least 20 mm and / or at most 100 mm, preferably at least 30 mm and / or at most 70 mm. The distance is preferably 50 mm ± 10 mm. The distance can optionally be adjustable.

[0027] The fourth section can be concave toward the first section. The first section can be concave toward the fourth section. The first section and / or the fourth section can be concave, particularly at least in some areas, with a radius of at least 10 mm and at most 40 mm, or can be provided with the radius. The concave shapes of the first and fourth sections can point toward each other, particularly to enclose a round hand rest, for example, in the most surface-wide contact possible.

[0028] The holder can have a / the main part, in particular for attachment to a photovoltaic module. The main part can have at least a part of the second section, in particular the second section, and optionally at least one further section, in particular an entire further section, or can be formed therefrom. The main part can be rod-shaped. For example, a first part of the first section and the second section are formed integrally with one another to provide the main part of the holder. The main part can provide the first section, the second section, the third section, and / or a fifth section, each preferably at least partially or completely.

[0029] It is possible for at least one of the sections to be provided, at least partially or completely, by an adjustment part. For example, a further part of the first section and the third section are formed integrally with one another to provide the adjustment part. The main part and the adjustment part can be fastened or fastened to one another so as to be adjustable relative to one another along the first section. At least one of the main part and the adjustment part can have a passage, in particular designed as an elongated hole. For example, the parts of the first section can each be provided with the passage, in particular an elongated hole, in order to obtain adjustability of a length of the first section using a screw connection or the like, such that a distance between the second and third sections is adjustable.

[0030] The adjustment part can be L-shaped or L-shaped. The L-legs can be of the same or different lengths. Each L-leg can be provided with a passage, in particular an elongated hole. One of the L-legs can form the third section, and the other of the L-legs can form at least a (further) part of the first section. The adjustment part can thus be attached to the support part in different arrangements and adjustment positions to accommodate balcony railings of different widths or heights.

[0031] It is possible for the adjustment part and the securing part to be similarly shaped, for example, L-shaped. The preferred configurations mentioned with regard to the adjustment part and the securing part can be provided in an analogous manner on the respective other part.

[0032] The holder can have at least one screw connection, for example with a screw and preferably a nut corresponding to the screw. The at least one screw connection can be provided for fastening the securing part, in particular to the third section or to the first section, for example to the adjustment part or to the main part. The at least one screw connection can be provided for fastening the adjustment part to the main part or to the other part of the first section. The at least one screw connection can comprise a metric thread. The at least one screw connection can comprise an M4, M5, M6, M7, M8, M9, M10, M11 and / or M12 thread. The thread pitch of the thread can be 1.0 mm, 1.25 mm, or 1.5 mm. The at least one screw connection can comprise a carriage bolt, which can, for example, engage positively in a passage in order to be arranged therein in a rotationally fixed manner.The at least one screw connection can provide the fourth section, for example at a free end.

[0033] The second section can have at least one passage for attachment to a photovoltaic module. The at least one passage can comprise a first passage configured as an elongated hole, preferably extending along the second section. The at least one passage can comprise a further passage configured as an elongated hole, preferably extending along the second section and / or being provided along the second section at a distance from the first elongated hole. The elongated holes can essentially lie in a line. The elongated holes enable flexible attachment to differently configured photovoltaic modules.

[0034] To accommodate photovoltaic modules of various commercially available sizes, the second section can have a length of at least 1 m and / or a maximum of 1.4 m. The length is preferably 1.2 m ± 0.1 m.

[0035] The holder preferably has a / the fifth section for attachment to a frame of a / the photovoltaic module. The second section and the fifth section are preferably firmly connected to one another and / or extend transversely to one another. The second and the fifth section are preferably formed integrally with one another. For example, the fifth section is shorter than the second section in order to partially encompass the frame of a / the photovoltaic module.

[0036] The first section, the second section, and / or the third section may be made of metal. The locking part may be made of metal or plastic.

[0037] A thickness of the first, second, third, and / or fifth section can be at least 2 mm and / or at most 8 mm. The thickness is preferably 5 mm ± 2 mm. A width of the first, second, third, and / or fifth section can be at least 10 mm and / or at most 100 mm. The width is preferably 15 mm ± 10 mm or 80 mm ± 10 mm. For example, the main part and / or the adjusting part are made of metal material, for example flat material, in particular flat steel. The main part and / or the adjusting part can be formed from a bent, originally flat semi-finished product, e.g. flat steel. For example, several sections, in particular those that are connected or formed integrally with one another, have the same thickness and / or width.

[0038] The metal material or metal substance from which the bracket or parts of the bracket can be formed preferably comprises or consists of a steel material and / or an aluminum material. For example, material numbers 1.4301, 1.4541, or 1.4307 can be used as the steel or steel material. A stainless steel such as V2A or V4A is preferably used.

[0039] Galvanized steel can be used. Aluminum materials offer a weight advantage over steel. Depending on the design and manufacturing process of the bracket, aluminum materials may be easier to manufacture than steel. However, depending on the design and manufacturing process of the bracket, steel materials may be easier to manufacture than aluminum materials. In this respect, both materials—steel and aluminum—can offer advantages.

[0040] At least one flexible support material can be provided. The support material can be secured to the first section and preferably to the fourth section for resting on and / or against a balcony railing. It is also possible to provide the flexible support material to the second and / or third section. The flexible support material can be made of plastic and / or rubber, for example. The flexible support material can be self-adhesive and, in particular, can be glued to the respective section. The support material can protect the balcony railing and the bracket from scratches or the like and / or reduce noise transmission.

[0041] Furthermore, a kit for fastening a photovoltaic module is proposed. The kit has, for example, two or more of the brackets. Alternatively or additionally, the kit has the bracket, wherein various adjustment parts and / or securing parts are provided. The kit can have at least one fastening strap or a fastening belt, in particular cable ties, e.g. metal cable ties and / or stainless steel cable ties, and / or Velcro fasteners, e.g. belt with Velcro fastener. A safety rope can be provided as the fastening strap, for example to secure a photovoltaic module against falling, wherein the fastening strap can catch the photovoltaic module. With the fastening strap, the bracket can optionally also be fastened to the balcony railing. The kit can meet various fastening requirements without having to offer different variants.

[0042] Furthermore, the use of a bracket or kit for attaching a photovoltaic module to a balcony railing is proposed. The photovoltaic module can be part of a balcony power plant.

[0043] For example, a balcony power plant is proposed which comprises the kit and / or a / the holder, in particular several of the holders, a photovoltaic module and preferably an inverter and preferably a battery storage unit.

[0044] Furthermore, a method for producing a / the holder is proposed. The method preferably comprises providing a metal material, preferably steel, in particular V2A or V4A. The method further preferably comprises machining the metal material to produce the first section, the second section, the third section, preferably the fifth section, and preferably the securing part. The machining preferably comprises a forming process, a jet cutting process, a machining process, and / or a primary forming process.

[0045] In the context of the disclosure, the abbreviation "bzw." (respectively) is a shortened form of "respectively" and is generally intended to indicate alternative, essentially equivalent, and / or synonymous features or terms in order to clarify the idea or meaning of a feature or term. "Respectively" and "or" can always be replaced with "and / or." Optional features, i.e., those disclosed in conjunction with "in particular," "for example," "preferably," "preferably," "optional," "can," or the like, can be used individually to further develop the invention.

[0046] The invention is explained below by way of example with reference to the accompanying drawings using preferred embodiments, wherein the features presented below can represent an aspect of the invention both individually and in combination. Where the same reference numerals are used in the figures, the following description applies accordingly to the figures below. They show: Fig. 1A-F a bracket for, for example, round balcony railings in different perspective views; Fig. 2A-C another bracket for, for example, square balcony railings in different perspective views; Fig. 3A-E the bracket Fig. 2 in different arrangements; Fig. 4 another bracket for, for example, square balcony railings in a perspective view; Fig. 5A-B a kit with two brackets for attaching a photovoltaic module, wherein the brackets are attached to the photovoltaic module; and Fig. 6 another kit; and Fig. 7 a fastening of a bracket to a balcony railing by means of a fastening strap designed as a stainless steel cable tie.

[0047] The figures show various embodiments, with identical reference symbols or feature names representing identical or at least similar features. The description can be applied analogously in this respect.

[0048] Fig. 1, in particular Fig. 1A-F, shows a holder 1 for fastening a photovoltaic module 200 to a particularly round balcony railing 100, for example balcony railing 100 with a round or cylindrical hand rest.

[0049] The bracket 1 has a first section 10 for resting on a balcony railing 100. The first section 10 is concave or round in shape for support, see. Fig. 1C.

[0050] The holder 1 has a second section 20 for attachment to a photovoltaic module 200. The first section 10 and the second section 20 are firmly connected to one another and extend at least partially or in sections transversely to one another.

[0051] The holder 1 has a third section 30. The third section 30 is arranged opposite the second section 20. The second section 20 and the third section 30 run parallel to each other in this case.

[0052] The first section 10 essentially forms a curved, in particular semicircular, connection between the second section 20 and the third section 30. The first section 10 basically runs transversely or obliquely to the second section 20 and the third section 30 with an angle that varies along the first section 10.

[0053] It is possible for the first section 10 to be curved in some areas and straight or elongated in other areas. For example, two of the sections 10, 20, 30 can merge into one another in a curved manner.

[0054] The holder 1 has a substantially L-shaped securing part 5 for fastening to the second section 20 and / or the third section 30. The securing part 5 is in Fig. 1A-D is arranged on the third section 30 and can be adjusted along the second 20 or third section 30. In Fig. 1E, the securing part 5 is arranged on the second section and is adjustable along the second or third section 30.

[0055] As in Fig. As shown in Figures 1D-E, the securing part 5 can be screwed in different positions or at different points on the main part 2 by means of screw connection 6.

[0056] The securing part 5 provides or has a fourth section 40. The fourth section 40 is arranged or is arranged opposite the first section 10. More specifically, the fourth section 40 is arranged opposite the first section 10 in order to secure a photovoltaic module 200.

[0057] The securing part 5 has at least substantially a shape with two leg sides. More precisely, the securing part 5 has an L-shape or at least a shape similar to an L-shape. The first of the two leg sides provides the fourth section 40 and is curved in this case to be concave in some areas. The first of the two leg sides forms a free end of the securing part 5, which projects towards the opposite section, in this case the second section 20. The second of the two leg sides is intended for contact with and / or attachment to the third section 30, cf. Fig. 1A-F. The thigh sides are essentially oriented transversely to each other.

[0058] The securing part 5 can be arranged on a side of the third section 30 facing the second section 20 on the third section 30, preferably abutting thereon, in particular abutting thereon flatly.

[0059] The securing part 5 has a passage 42, for example, a round or square opening for inserting a screw, preferably a carriage bolt. A screw can be inserted through the passage 42 with its threaded side facing away from the second section and through a passage 32 of the third section 30. The passage 42 is intended to align with a passage 22, 32 in the main part 2 or to be secured thereby. Optionally, the passage 32 of the securing part 5 is an elongated hole.

[0060] The third section 30 has the passage 32, in particular for fastening the securing part 5. The passage 32 is an elongated hole in the present case. The elongated hole extends along the third section 30, for example, to fix the securing part 5 in various positions.

[0061] A distance A between the second section 20 and the third section 30 is between 30 mm and 70 mm. In this case, the distance A is 50 mm ± 10 mm. If the first section 10 has a semicircular shape, the distance A generally corresponds to twice the radius R of the semicircular shape, optionally with ± 10% or another deviation. The distance A can essentially correspond to a length of the first section 10, typically measured transversely or perpendicularly to the second section 20 or third section 30.

[0062] In this case, the fourth section 40 is concave towards the first section 10. The first section 10 is concave towards the fourth section 40. The first section 10 and the fourth section 40 are concave with a radius R of at least 10 mm and at most 40 mm. For example, the radius R is 30 mm ± 10 mm or 25 mm ± 10 mm. The first section 10 and the fourth section 40 can accommodate a round balcony railing 100 between them in order to lie flat against them at least in some areas and provide secure support, cf.

[0064] In each case, a flexible, in particular self-adhesive, support material 7 is fixed for resting on and / or attaching to a balcony railing 100 on the first section 10 and on the fourth section 40, cf. Fig. 1C-E. For example, the flexible support material 7 comprises plastic, rubber, felt, and / or the like.

[0065] In the present case, a screw connection 6 is provided for fastening the securing part 5. In particular, the securing part 5 can be secured to the second section 20 with the screw connection 6, cf. Fig. 1E, and / or the third section 30, cf. Fig. 1D. The screw connection 6 allows the locking part 5 to be adjusted. The screw connection 6 includes a metric M6 or M8 thread. Here, the screw connection 6 includes a screw or bolt with an external thread and a nut with an internal thread matching the external thread.

[0066] A nut used for fastening may be a lock nut. The nut may be self-locking.

[0067] It is possible for screw connections 4 and 6 to be designed without washers on one or both sides. Surprisingly, washers have proven to be unnecessary.

[0068] The screw connection 6 can have galvanized parts or be galvanized. It is possible to use stainless steel, such as V2A or V4A, for the screw connection and / or to omit galvanization.

[0069] The second section 20 has two passages 22, 24 for attachment to a photovoltaic module 200, wherein the two passages 22, 24 extend along the second section and are spaced apart from one another along the second section 20. More precisely, the two passages 22, 24 are each an elongated hole extending along the second section 20.

[0070] A photovoltaic module 200 can be attached to the passages 22, 24. In particular, the securing part 5 can optionally be attached to the passage 22.

[0071] Along the second section 20, the passage 22 or the elongated hole is dimensioned with a length of 23. The length 23 is preferably at least 10 mm and preferably at most 400 mm. In the present case, the length 23 is 250 mm ± 100 mm or 25 mm ± 15 mm. B22

[0072] Along the second section 20, the passage 24 or the elongated hole is dimensioned with a length of 25. The length 25 is preferably at least 10 mm and preferably at most 400 mm. In the present case, the length 23 is 250 mm ± 100 mm or 25 mm ± 15 mm.

[0074] The second section 20 has a length 21 approximately between 1 m and 1.4 m. The length 21 in this case is 1.2 m ± 0.1 m.

[0075] The holder 1 further comprises a fifth section 50 for attachment to a frame 202 of the photovoltaic module 200. The second section 20 and the fifth section 50 are firmly connected to one another. The second section 20 and the fifth section 50 extend transversely, preferably perpendicularly, to one another.

[0076] The fifth section 50 has a passage 52, for example a bore for fastening the fifth section 50 to a photovoltaic module 200. A photovoltaic module 20 can be screwed through the passage 52 in the direction along the second section 20.

[0077] The first section 10, the second section 20, and the third section 30, and preferably the fifth section 50, are formed integrally with one another to provide a main part 2. The first section 10, the second section 20, and the third section 30, and preferably the fifth section 50, are made of metal. The fourth section 40, or the securing part 5, can be made of metal or plastic.

[0078] For example, the main part 2 and / or the securing part 5 are formed flat material or formed flat steel. The main part 2 and / or the securing part 5 can be galvanized and / or made of stainless steel.

[0079] A thickness T of the first section 10, the second section 20, and the third section 30, and preferably of the fifth section 50, is 5 mm ± 2 mm in the present case. In other words, the flat material can have a thickness T.

[0080] A width B of the first section 10, the second section 20, and the third section 30, preferably the fifth section 50, is 15 mm ± 10 mm in the present case. In other words, the flat material can have a width B.

[0081] Fig. 2 and Fig. 3, in particular Fig. 2A-C and Fig. 3A-E, show a bracket 1 for fastening a photovoltaic module 200 to a balcony railing 100, for example balcony railing 100 with a hand rest that is flat on the top, front and / or back and / or partially square in cross-section.

[0082] The bracket 1 has a first section 10 for resting on a balcony railing 100. The first section 10 is shaped flat for resting.

[0083] The holder 1 has a second section 20 for attachment to a photovoltaic module 200. The first section 10 and the second section 20 are partially firmly connected to one another and run transversely, in particular perpendicularly, to one another.

[0084] The holder 1 has a third section 30. The third section 30 is arranged opposite the second section 20. The second section 20 and the third section 30 run parallel to each other in this case.

[0085] At the Fig. 2 and Fig. In the embodiment shown in Figure 3, a first part of the first section 10 and the second section 20 are formed integrally with each other to provide a main part 2. Another part of the first section 10 and the third section 30 are formed integrally with each other to provide an adjustment part 3.

[0086] The main part 2 and the adjustment part 3 are to be fastened or attached to each other in a manner that is adjustable relative to each other along the first section 10. The main part 2 and the adjustment part 3 each have a passage 12, 13 designed as an elongated hole. The passages 12, 13 are to be aligned with each other in order to be fastened to each other, for example by means of a screw connection 4, in particular with a metric M6 or M8 thread, see also Fig. 3A-E. In the present case, the screw connection 4 has, by way of example, a carriage bolt that protrudes through the passages 12, 13, in order to be screwed tight with a nut facing away from the first 20, third 30, and / or fourth section 40. The carriage bolt can be non-rotatably seated in the passage 12, so that loosening and tightening of the screw connection 4 is essentially possible with just a single tool, e.g., a ratchet, or without countersunk screws.

[0087] Fig. 3A-D shows various fastening possibilities of the holder 1 itself, in particular in the form of different fastenings or arrangements of the main part 2, the adjustment part 3, and the securing part 5 to one another. Fig. 3E finally shows the bracket 1 attached to a balcony railing 100 in the arrangement of Fig. 3A.

[0088] It can be seen that the securing part 5 can be adjusted along the third section 30 or the second section 20, cf. Fig. 3A-B or Fig. 3D. To adjust, first loosen the screw 6, then adjust the locking part 5, and finally tighten the screw 6.

The recess can extend along the respective section 10 or 30. The recess can be in the form of a groove. This design can improve ergonomics, as fewer body edges are exposed.

[0093] Fig. 5A shows a kit with two of the Fig. 2-3 shown brackets 1, for example for square and / or at least one-sided flat balcony railings 100. The brackets 1 are each screwed to a frame 202 of a photovoltaic module 200 by means of screw connections 204. The screw connections 204 engage through the passages 22 and 24 and can be screwed into the frame 202 itself or in the frame 202, e.g. as in Fig. 5B as a detail of the partially and sectionally shown kit of the Fig. 5A, by means of a nut. Due to the passages 22 and 24 in the form of elongated holes, photovoltaic modules 200 of different sizes or widths can be attached along the bracket 1.

[0094] Fig. 6 shows a kit with two of the Fig. 1, for example, for round balcony railings 100. The brackets 1 are attached to a photovoltaic module 200. The brackets 1 run at least substantially parallel to one another.

[0095] It is possible that a kit comprises different types, in particular different sizes, of adjustment parts 3 and / or securing parts 5. In Fig. 5 and Fig. 6, the brackets 1 are each attached to a photovoltaic module 200 of a balcony power plant in order to attach the photovoltaic module to a balcony railing 100. In this respect, a use of a bracket 1 or a kit for attaching a photovoltaic module 200 of a balcony power plant to a balcony railing 100 is shown.

[0096] Fig.Figure 7 shows a possible additional fastening of the second section 20 of a bracket 1 to the balcony railing 100. In the present case, a fastening strap 206 in the form of a metal cable tie or stainless steel cable tie is wound around the second section 20 and a section of the balcony railing 100. The fastening strap 206, in particular several of them, can be included in a kit.

[0097] A method for producing a holder 1 comprises, for example: Providing a metal material, Processing the metal material to produce at least the first section 10, the second section 20, the third section 30 and optionally the fifth section 50 and optionally the securing part 5.
