SUPPORT AND MOUNTING ARRANGEMENT FOR SOLAR MODULES

Description

[0001] The invention relates to a support arrangement which is provided and configured to support solar modules in a spaced-apart manner with respect to a surface covered by these solar modules.

[0002] Solar modules are mounted in a variety of designs on surfaces exposed to sunlight. Support structures are used to support and hold a number of solar modules in place, for example, against a roof surface. In addition, support structures are now also available that support the solar modules at any height and angle relative to a ground surface, thus forming a roof structure.

[0003] Since the support and fastening assembly (hereinafter referred to as the support assembly for simplicity) is naturally located outdoors together with the solar modules, it is naturally exposed to all weather phenomena, which can be accompanied by significant temperature fluctuations as well as the deposition of a wide variety of particles and various states of water (water, snow, ice). This leads to parts of the support assembly as well as the solar modules, which are usually framed, expanding and contracting, and moreover, water in the form of rain, for example, should and must be drained away from the surfaces of the solar modules. At elevated temperatures, for example in summer, it is also advantageous if the support assembly is appropriately ventilated behind it to dissipate heat.

[0004] From EP 2 187 146 A1, a support arrangement is known which is intended and configured to support solar modules at a distance from a surface covered by these solar modules, with at least two support channel profiles running parallel to one another, which are each provided with at least one support web, which in turn has a first longitudinal side and a second longitudinal side, wherein a plurality of solar modules are arranged between the support webs of the at least two support channel profiles, which in the position of use lie next to one another along their longitudinal sides, and with a plurality of rung parts, which each extend between the at least two parallel support channel profiles and each at least indirectly support frame pieces of two adjacent solar modules.

[0005] It is therefore the object of the present invention to provide a support arrangement for solar modules which, on the one hand, securely holds the solar modules of different manufacturers with different geometric dimensions on the support arrangement so that no relative displacement of the solar modules with respect to one another and / or the support arrangement takes place, wherein the support arrangement and the solar modules are permitted to expand or contract independently of one another, and, on the other hand, a possibility is created to drain moisture from the outside of the support arrangement essentially in such a way that it does not impinge on the covered area and a tight roof skin is formed structurally without the use of sealing rubbers.

[0006] This object is achieved by a support arrangement having the features of claim 1. The solution according to the invention therefore consists in particular in that it has at least two mutually parallel support channel profiles, which lie in one plane and are each provided with a support web and, on this, with a first and a second longitudinal side. Between the support webs of the at least two support channel profiles, a plurality of solar modules are arranged, which, in the position of use, lie next to one another along their longitudinal sides. Furthermore, a plurality of rung parts are provided, which each extend between the at least two parallel support channel profiles and at least indirectly support frame pieces of two adjacent solar modules.In addition, a plurality of holding elements are provided, which are held and supported in a detachably connectable manner with a first longitudinal side of the support web of a first of the at least two support channel profiles, wherein in each case an associated rung part receives a free end of a holding element on the front side in an engagement section at its first end.Finally, the support arrangement has a plurality of locking elements, each of which can be arranged or is arranged at a second end of one of the rung parts, which faces the second longitudinal side of a support web of a second of the at least two support gutter profiles, wherein each of the locking elements is designed to be movable at the second end of the respective rung part in a guide along its longitudinal extent and to be connected to the second longitudinal side of the support web of the second support gutter profile by sliding along the guide in such a way that the ends of the solar modules facing the second support gutter profile are held and locked together with the end of the rung parts on the support web of the second support gutter profile.

[0007] The assembly of the system as well as the locking of the locking element can advantageously be carried out from below as well as from above, which considerably simplifies the handling of the support arrangement.

[0008] According to the invention, solar modules are arranged between parallel support channel profiles of the support arrangement, with two adjacent solar modules, with their opposing frame elements, engaging with rungs extending between the support channel profiles, which in turn are secured to the different sides of a support web of the support channel profiles via holding and locking elements. The combination of features outlined above ensures that, on the one hand, the solar modules are securely held to the support channel profiles. On the other hand, the solar modules grouped into a module array and the support channel profiles are thermally decoupled in such a way that independent expansion and contraction of the components is possible, and, moreover, moisture can be easily drained away from the modules.By allowing water to flow into the lower of two support gutter profiles, a module field with solar modules arranged in rows on the support arrangement can be drained row by row.

[0009] This creates a static support gutter structure that is essentially scalable and implements a self-supporting PV roof system through screwless connection to photovoltaic (PV) modules (solar modules). Furthermore, it is irrelevant whether the solar modules are arranged "lengthwise" or "crosswise" in the arrangement; there is no preferred orientation.

[0010] Preferred developments of the support arrangement according to the invention can be found in the corresponding subclaims.

[0011] An advantageous development of the support arrangement according to the invention can consist in that the first longitudinal side and the second longitudinal side of the support webs of the at least two support channel profiles differ, and the at least two support channel profiles are each provided with a base from which the respective support web protrudes. The design with two different longitudinal sides makes it possible to provide different devices and mechanisms for securing the two ends of each of the plurality of rung parts to opposite support channel profiles. The respective support web is thereby expediently stabilized by the respective base.

[0012] In the support arrangement according to the invention, a plurality of the support gutter profiles can be arranged one behind the other in the direction of extension of the support gutter profiles. For this purpose, in another development of the support arrangement, the long sides of the support gutter profiles can be designed so as to be spaced apart from one another and connected at their upper and lower ends by the support gutter profile base and a roof piece, whereby a hollow space is formed in the respective support gutter profile. A stiffening or connecting element can be completely introduced into the aforementioned hollow space if a support gutter profile already spans a wide space on its own; in the same way, the two ends of a stiffening element can be introduced into hollow spaces that are assigned to two adjacent support gutter profiles in the longitudinal direction, so that the support gutter profiles can in principle be extended as desired in their longitudinal direction by means of the stiffening elements in the hollow spaces.

[0013] As already mentioned, further devices for supporting further elements of the support arrangement can be provided on the base of the at least two profiles. In a preferred development, each support web can have a support element that projects from the base and whose end supports an end region of a rung part. The respective end region of the rung part does not necessarily have to rest directly on the free end of the support element. Furthermore, further devices can be provided on the support elements that contribute to the stability and / or fastening of the support arrangement and are preferably found in the end regions of the support elements. For example, engagements can be provided on the end regions of the support elements, which can be brought into engagement, for example, with hook-like projections of an associated clamping element. This can be provided to fasten a support gutter profile to a roof structure.By means of these devices, a rung part can also be fixed to a support element, which is advantageous, for example, in the area of ​​the verge.

[0014] Additional stability can be provided to the structure with the rung sections by a further development in which a cross member can be arranged or is arranged between two rung sections, preferably between two rung sections each. This can improve the load-bearing capacity of the support arrangement according to the invention, for example, with regard to heavy snow and wind loads.

[0015] In another advantageous development of the support arrangement, the rung parts extending between the at least two parallel sections can have an upwardly open cross-section with a predeterminable length, in particular a C- or U-shaped cross-section, into which frame pieces of adjacent solar modules each engage and are received in the open cross-section of the associated rung part such that they extend toward one another there, predominantly parallel to one another, between the two support channel profiles. The rungs also serve for drainage between the modules and guide the water into the water-bearing space within the support channel profiles.

[0016] Prefabricated solar modules from different manufacturers can each be provided with different frame pieces, which in particular have a different vertical extension. Therefore, in a further development of the support arrangement, at least one spacer can be assigned to each rung part, which is detachably received in the cross-section of the rung part and forms a support for the frame pieces of the solar modules received in the cross-section. The spacer is adaptable or adapted to the respective vertical extension of the frame piece of the solar module(s) in such a way that the solar modules all protrude the same height from the base of the rung parts and can form a uniform surface towards the outside. The spacers are held in the cross-section of the rung parts by their material flexibility and shape, which allows prestressing relative to the side walls of the rung parts.Several spacers can also be provided per rung section, which further improves the support of the frame pieces.

[0017] According to the invention, the support arrangement is provided with a plurality of holding elements which are detachably held and supported by a first longitudinal side of the support web of a first of the at least two support channel profiles. In order to be able to hold the areas of solar modules in conjunction with the rungs and locking element in a suitable manner and securely and essentially stationary, each of the holding elements has a receptacle with an approximately C-shaped cross section and a receptacle base arranged parallel to the support web. The legs of the receptacle project substantially transversely from the vertically spaced ends of the receptacle base in such a way that the aforementioned corner areas of two adjacent solar modules are encompassed by the receptacle from at least two sides.

[0018] Solar modules with different surface extensions are available to cover different sized areas. To adapt the support arrangement to these different extensions, for example, with respect to a transverse extension of the solar modules running parallel to the support webs, each of the holding elements can be provided so that it can be displaced along the first longitudinal side of the support web. A hook-like projection on the side of the receiving base facing the first longitudinal side engages a hinge opening on the longitudinal side, thereby pivoting the holding element relative to the support web.Due to this pivoting capability, the base of the C-shaped holder of the holding element can be pivoted relative to the first longitudinal side of the support web, releasing the end of the hook-like projection inserted into the hinge opening from a type of clamping, allowing it to be easily moved along the longitudinal side of the support web. Even in a locked position, the holding element can be moved slightly. This ensures that no thermally induced stresses arise in the system. Furthermore, the holding elements maintain a distance between the solar module and the support web, thus enabling rear ventilation and drainage of the modules.

[0019] In another development of the support arrangement, the holding element is supported by a support web on the first longitudinal side of the support web in such a way that a solar module received in the receptacle of the holding element can be supported on the support web via the receptacle base of the receptacle.

[0020] In order to be able to fix each of the holding elements in the desired position after determining the respective location on the support web, in an advantageous development of the support arrangement according to the invention, the holding element can be secured to the support web. For this purpose, the free end of the holding element received in the engagement section of the rung part and a locking arm can expediently be arranged at an end of the receptacle facing the base of the support channel profile, the free end of which is designed to lock with a locking projection on the support web (on the long side of the support web) and thus secure the holding element. In this case, the locking arm can, for example, form a curved section of the holding element and, although arranged at an end of the receptacle facing the base of the support profile, can be arranged at the free end of the leg facing the rung part.The end of the curved section can, in turn, be provided with a locking lug, which, when appropriate pressure is applied against the retaining element in the direction of the support web, engages with the locking projection projecting diagonally from the support web toward the bottom of the support channel profile. The locking arm with its curved section can preferably form an angle of approximately 90°, but other angular positions with respect to the locking projection are also conceivable. Likewise, the entire locking arm can also be designed differently.

[0021] In order to secure solar modules arranged on the second longitudinal side of the support web or the support channel profile against lifting from their use position, another advantageous development of the support arrangement according to the invention provides for a transverse web to be arranged at the free end of the support web. This cross web projects from the second longitudinal side and overlaps the surface of the end regions of adjacently arranged solar modules facing this longitudinal side. Said transverse web can protrude transversely from the support web.

[0022] In order to ensure that the design of the plurality of locking elements can be kept flexible, at least within limits, in order to be adaptable to certain structural changes to the support web with its second longitudinal side, another development of the support arrangement can provide the locking elements in multiple elements with a holding element, a locking element, and a guide element, wherein the holding element and the locking element extend essentially parallel to one another and to the second longitudinal side of the support web, while the guide element projects transversely thereto in the direction of the rung part. The elements in a parallel arrangement, i.e. the holding element and the locking element, can be stepped parallel to one another, i.e. with an oblique connecting piece between them such that the two elements adjoin one another. However, the two elements can also be collinear.The retaining element pointing away from the connecting piece, i.e., the step between the links, can be placed in the area of ​​the connecting piece. A possible locking element, for example, could be a kind of three-winged, yet one-piece structure.

[0023] According to the invention, the locking member of the locking element is configured, during locking of the locking element, to overcome a cross-sectional change of the second longitudinal side of the support web by moving its free end along the rung part. This change blocks the reverse movement of the locking element in such a way that the respective locking can only be released with a certain amount of force, which pushes the locking member back behind the cross-sectional change. The cross-sectional change can, for example, be designed such that, in the direction of the support channel profile base, the respective longitudinal side of the support web itself forms a recess, which the locking member, and with it the locking element, overcomes during locking, and against which the locking member abuts during the reverse movement in order to be held back.During the locking process, apart from a displacement of the two solar modules engaging in the glazing bar toward the first longitudinal side of an opposing support channel profile, no further force is exerted on the solar module, so that the solar modules are arranged mechanically stress-free on the support structure in their use position. Furthermore, they are thermally decoupled from the support channel profiles by being secured by the retaining elements and the locking elements, allowing them to expand and contract independently of each other.

[0024] For both the retaining element and the locking element, a certain degree of flexibility is beneficial to their function, provided the respective component is stable, for example, so that the locking element and its locking member can overcome the change in cross-section. Suitable structures with suitable material flexibility can, for example, be made at least partially of aluminum. However, other materials are also conceivable.

[0025] To enable the support arrangement according to the invention to form a tight roof covering that appropriately covers the area located beneath it, an advantageous refinement provides that the support gutter profiles are each connectable or connected to a structural element of a roof structure. The support gutter profiles can be secured, for example, to the rafters as structural elements of a roof structure. For this purpose, they can be secured using clamping elements that can, for example, be engaged with a corresponding recess in the support elements of the support gutter profiles. However, other fastening methods are also conceivable. Furthermore, the support gutter profiles can be connected to purlins as structural elements in order to achieve larger spans. They can be connected to these purlins, for example, by screwing or welding.

[0026] In the context of the discussion of the cavity in the support web, it was already mentioned that the support channel profiles of the support arrangement can be continued along their longitudinal direction by similar, particularly identical, support channel profiles, i.e., can be extended, thereby enabling an essentially unlimited extension in a first installation direction (and thus also spatial direction). Furthermore, in a further development of the support arrangement, a number of n mutually parallel support channel profiles can be provided, where n is a natural number greater than or equal to two, whereby the spatial direction perpendicular to the previous one is also unlimited.

[0027] In order to be able to adapt to certain geometric requirements such as changes in the ground profile, but also to satisfy certain aesthetic aspects, a further development of the support arrangement can provide the support gutter profiles to arrange the solar modules of the support arrangement relative to one another in such a way that the solar modules each form surface pieces of the same plane or curved surface. This means that in the case of a purely horizontal extension in the two mutually perpendicular spatial directions, the solar modules not only form a tight roof skin, but the module field is also essentially flat. In addition, however, with appropriately curved lattice parts, for example, the support arrangement can also have a curved cross-section, so that, for example, a curved surface in the area of ​​a roof ridge can be created using the support arrangement.Depending on the curvature of the solar modules, various designs are conceivable, which can be arranged next to or behind each other, for example to form a kind of curved row.

[0028] The above embodiments and further developments can be combined with one another as desired, where appropriate. Further possible embodiments, further developments, and implementations of the invention also include combinations of features of the invention not explicitly mentioned above or described below with respect to the exemplary embodiments.

[0030] The accompanying drawing figures are intended to provide a deeper understanding of embodiments of the invention. They illustrate embodiments and, in conjunction with the description, serve to explain principles and concepts of the invention. Other embodiments and many of the aforementioned advantages will become apparent with reference to the drawing figures. The elements of the drawings are not necessarily shown to scale.

[0031] In all figures, identical or functionally identical elements and devices are provided with the same reference numerals, unless otherwise indicated.

[0032] The Fig. 1 shows a planar side view of a first embodiment of a support assembly, designated as a whole by 10, with two opposing support channel profiles 20, 30, rung parts 40 extending between the support channel profiles 20, 30, and solar modules 100 arranged on the support assembly 10, wherein the support assembly is fixed to a rafter 14 by means of clamping elements 16 and has a ridge side and an eaves side. In Fig. 1 The mounting situation of the support assembly 10 is shown, in which solar modules are arranged on a roof structure, here in the form of a rafter 14. The upper ridge side is located at the second support gutter profile 30 shown on the right in the figure, while the lower eaves side is located at the first support gutter profile 20 shown on the left in the figure. A lattice part 40 extends between the mutually parallel support gutter profiles 20, 30 and accommodates a frame piece 102 of a solar module 100 that extends parallel to the lattice part 40. The solar module 100 is held on the support assembly 10 between the two support gutter profiles 20, 30. More precisely, it extends between the first longitudinal side 21 of the first support gutter profile 20 and the second longitudinal side 32 of the second support gutter profile 30.The solar module is secured to the support assembly 10 by the holding element 50 located on the first longitudinal side 21 of the first support channel profile 20 and the locking element 60 located on the second longitudinal side 32 of the second support channel profile 30. Further, FIG. Fig. 1 nor that the solar module 100 is supported with its frame piece 102 on the rung part 40 associated spacers 44, which support the frame pieces 102 against the bottom of the rung part 40. Further reference numerals are on the Fig. 1 omitted for reasons of clarity.

[0033] The following Figuren 2 bis 8 show a chronological sequence of an assembly of a support arrangement 10 with first and second support channel profiles 20, 30, rung parts 40 extending between them, holding elements 50 and connecting elements 60.

[0034] The Fig. 2a, 2b shows a planar side view of a second embodiment of a support arrangement 10 with two opposing support channel profiles 20, 30, rung parts 40 extending between the support channel profiles 20, 30, in which the support channel profiles 20, 30 have the same height ( Fig. 2a ) and an enlargement of an end region of a rung part on which a locking element 60 is arranged ( Fig. 2b ). Here, the locking element 60 is inserted with a guide member 66 in the direction of the arrow into a guide 46 at the second end 42 of the rung part 40. The first end 41 of the rung part 40 is brought close to the first support channel profile 20 of the support arrangement in order to be arranged there.

[0035] The Fig. 3a, 3b show a flat side view of the support arrangement of the Fig. 2a, 2b with a locking element 60 arranged on one rung part end 42, wherein the rung part 40 is moved in the direction of the first support channel profile 20, on whose first longitudinal side 21 the holding element 50 is arranged. The first support channel profile 20 shows a structure which is also valid for the second (identical) support channel profile, with a support channel profile base 23, a support web 24 arranged thereon and protruding from the support channel profile base 23 and having a transverse web 26. In addition, a support element 28, 29 projects from the support channel profile base to each longitudinal side 21, 22 for supporting rung parts 40, the support elements 28, 29 being aligned essentially parallel to the support web 24.

[0036] The holding element 50 arranged on the support channel profile 20 in the Fig. 3b forms a receptacle 51 which is approximately C-shaped in cross-section and parallel to the support web 24. The holding element 50 is provided so as to be displaceable along the first longitudinal side 21 of the support channel profile 20 or the support web 24, wherein it engages with a hook-like projection 53 on the side of the receiving base 52 facing the longitudinal side into a hinge opening 54, whereby the holding element 50 is designed to be pivotable relative to the support web 24. In addition, the holding element 50 is supported by a support web 55 on the first longitudinal side 21 of the first support channel profile 20 or the support web 24.On a receiving leg 56a of the receptacle 51 facing the support channel profile base 23 of the support channel profile 20, the free end 57 of the holding element 50 received in the engagement section 48 of the rung part 40 and a locking arm 58 are arranged, the free end of which is designed to lock with a locking projection 59 on the support web 24 and thus to fix the holding element 50 and thus later the solar module 100.

[0037] The Fig. 4a, 4b show a planar side view of the support arrangement 10 of the Fig. 3a, 3b in which the end region 41 of the rung part 40 facing the first support channel profile 20 receives the free end 57 of the holding element 50 and the other, second end 42 of the rung part 40 is pivoted in the direction of the second support channel profile 30. The features of the second support channel profile are provided with the reference numerals assigned to them, but the second support channel profile 30 can be seen in a continuation of the support arrangement in the view of the Fig.4 To the right, a first support channel profile 20 is formed, and further to the right, a second support channel profile 30 is arranged. The same applies to the continuation of the support arrangement to the left side for the viewer.

[0038] The Fig. 5a, 5b show a planar side view of the support arrangement 10 of the Fig. 4a, 4b in which the second end region 42 of the rung part 40 facing the second support channel profile 30 is pivoted to the respective support channel profile 30, shortly before the end region 42 of the rung part 40 comes to rest on the support element 38 of the second support channel profile 30. In the Fig. 5b It can be seen that in this position of the rung part 40, the locking element 60 arranged thereon, which is inserted into the guide 46 with the guide member 66, is brought with its holding member 62 and its locking member 64 close to the second longitudinal side 32 of the second support channel profile 30 in such a way that the end of the locking member 64 engages behind a cross-sectional change 65 of the support web 34. The directional arrows here indicate that the end region 42 of the rung part 40 is moved downwards in the direction of the support element 38 and the locking element 60 is moved to the right, as viewed by the viewer, in the direction of the support web 34. It can be seen from the locking member 60 that the holding member 62 and the locking member 64 are collinear with one another, and the guide member 66 points in the direction of the rung part 40.

[0039] The Fig. 6a, 6b show a planar side view of the support arrangement 10 of the Fig. 5a, 5b in which the rung part 40 extends between the support channel profiles 20, 30 and in which a solar module 100 is arranged on the support arrangement 10, wherein initially an end region of the solar module 100 is arranged near the second longitudinal side 32 of the second support channel profile 30 and the second end region 42 of the rung part 40. The second end region of the rung part 40 sits on the support element 38 on the second longitudinal side 32 of the second support channel profile 30, while the locking element 60 with its holding member 62 rests against the second longitudinal side 32 of the second support channel profile and the free end of the locking member 64 is supported on the cross-sectional change 65 of the support web 34.

[0040] The Fig. 7a, 7b show a planar side view of the support arrangement 10 of the Fig. 6a, 6b in which the solar module 100 with its frame piece 102 is accommodated in the rung part 40, and the front end of the solar module 100 facing the first support channel profile 20 is moved towards the first longitudinal side 21 of the first support channel profile 20 by sliding, which is indicated by the directional arrow of the Fig. 7b This end of the solar module engages under the receiving leg 56b arranged at the upper end of the holder 51 facing away from the support channel profile base 23 and can no longer deflect away from the support channel profile base 23. Furthermore, the cross section of the Fig. 7a that the support channel profile base 23, the support element 29, the first end region 41 of the rung part 40 together with the free end 57 of the holding element 50 as well as the locking arm 58, the locking projection 59 and a lower section of the support web 24 enclose a construction space 74 which is continued in the viewing direction and is then not always completely enclosed and is used for the drainage of the support arrangement 10. The Fig. 8a, 8b show a planar side view of the support arrangement 10 of the Fig. 7a, 7b in which the solar module 100 is secured to the support assembly 10 by locking the locking element 60 on the second longitudinal side 32 of the second support gutter profile 30. For this purpose, the locking element, guided by its guide member 66 in the guide 46 of the rung part 40, is moved in the direction of the rung part 40, whereby its locking member 64 is pressed in front of the cross-sectional change 65 on the one hand due to its sufficient flexibility, and on the other hand due to its sufficient rigidity and the shape of the cross-sectional change 65 of the support web 34 as a recess 68 on the second longitudinal side 32 of the support gutter profile 30, has no opportunity to re-engage with this. The cross-sectional change 65 of the support web 34 here consists in the fact that in its section facing the support channel profile base 33, the cavity 35 is formed, which has a quadrangular edge in cross-section, in one end region of which the aforementioned recess 68 is formed.The solar module 100 is secured upwards by a transverse web 36 pointing transversely away from the support web 34, which is arranged at the free end of the support web 34, protrudes therefrom, and engages over the surface of the end regions of adjacently arranged solar modules 100 facing this longitudinal side 32. A discharge piece 67 is formed on each side of the guide member 66 of the locking element, starting at the end facing the other members 62, 64, and extending so far toward the free end of the locking piece that, regardless of the movement path of the locking member 66, no side region of the guide member 66 is ever exposed without a discharge piece 67. In this way, it can be prevented that moisture to be discharged from the solar modules 100 can escape from the cross section of the rung parts 40.

[0041] The Fig. 9a, 9b shows a perspective view from above of a section of a support arrangement 10 without solar modules 100 and an enlargement of the frontal area of ​​a basically arbitrary first or second support channel profile 20, 30 with its two longitudinal sides 21, 22, 31, 32. Fig. 9a that the support assembly 10 can be extended both longitudinally and transversely. At one lateral end of the support assembly, at a so-called verge, a narrower lattice section can be provided, into which only one frame piece of a solar module 100 engages, since only one frame piece is to be held here.
