Description

Solar module arrangement with two angularly arranged to each other solar modules

The invention relates to a solar module arrangement having two solar modules arranged at an angle to one another, each solar module having an active region for converting solar energy and a supporting structure fastened to the active region, in particular arranged at the rear side of the active region.

Such angularly arranged to each other solar modules are used in particular on flat roofs in order to equip as possible a large proportion of the flat roof surface with solar modules can. Due to the angular arrangement of the solar modules relative to each other, so-called zigzag or Hüttchenanordnungen arise.

Compared to normal roofs, which already give a slope, have their own substructures are provided in flat roof arrangements with angularly arranged solar modules. However, known in the art module assemblies, such as in DE 100 47 400, DE 20 2008 007 549 or DE 20 2009 011 880 shown substructures are either associated with a high cost of materials, or difficult to assemble. For example, the assembly of the coupling connector in the ridge and floor area in DE 20 2009 011 880 is cumbersome.

It is therefore the object of the present invention to provide a solar module assembly which is suitable for flat roofs and at the same time allows easy and quick installation.

This object is achieved with the solar module arrangement according to claim 1. Accordingly, the solar module arrangement comprises two solar modules arranged at an angle to one another, each solar module having an active region for converting solar energy and a supporting structure fastened to the active region, in particular arranged on the rear side of the active region. This solar module arrangement is characterized in that the two supporting structures in the region of their mutually facing upper ends only abut each other.

The fact that there is no coupling in the upper region of the supporting structures as in the prior art, a simpler installation is possible. Surprisingly, it has shows that the solar modules are so stiff in connection with the supporting structures that a contact with each other in the upper area is sufficient without an additional coupling. This is the case in particular with thin-film solar modules. These comprise an active region with an active layer, which is arranged on a front glass, and a rear glass. In this case, the active layer is arranged between the front glass and the back glass. The sandwich construction may possibly have further layers, such as reflection layers. These modules have the support structure mounted on the back glass.

The support structure may preferably have a contact plate toward the upper edge of an active region. In the assembled state, the two solar modules abut each other via the contact plates. Plates allow easy installation, as due to the larger surface of the plates the juxtaposition of the solar modules during assembly is simplified.

More preferably, the contact plate can be integrally formed with the support structure. This also simplifies the assembly, since no additional element must be attached to the support structure.

Alternatively, however, the contact plates could also be detachably fastened to the support structure, wherein, in particular, the angle between the surface normal of the contact plate and the surface normal of the active region can be set within a predetermined range. This variant has the advantage that standard modules, such as those used with normal gable roofs, can also be used for flat roof mounting. In particular, the transport is simplified because the modules can be transported in the standard packaging.

In which the angle is adjustable, unevennesses in the flat roof or different orientations of the solar modules relative to the base can be realized. In order to attach the bearing plate to the supporting structure, this can for example be formed with a pin which can be inserted into a cavity of the supporting structure. Alternatively, the support structure can be inserted into a U-shaped partial element of the contact plate and connected by pins or screws to the support structure.

More preferably, the contact plate may have a roughened surface. The roughened surface is arranged on the surface of the contact plate, to which the contact plate of the second solar module is applied. This shifts the modules against each other. prevents or impedes others. Alternatively, the abutment plate could have an elastic layer.

According to a further preferred embodiment, the supporting structures of the two modules can be spaced apart from the region of their mutually facing upper ends, in particular in the region of their ends remote from each other, connected to each other via a pull rod or a pull rope. The torsional stiffness of the solar modules and the pull rod or pull rope cause the fixation of the desired geometry. Since usually a support structure is already provided at predetermined locations with mounting holes, they can be used to mount the traction cables, or tie rods. According to a variant, several tie rods and / or tension cables can be used per module pair.

According to a preferred embodiment, the ends of the support structure via a contact element, in particular a double profile element, only abut each other. Although an additional element is used here, similar to the double profiles used in saddle roofs, they are inserted and fastened in the adjacent rows of solar modules, but this is not coupled to the supporting structures according to the invention but merely serves as an intermediate piece against which the two supporting structures abut. As a result, the advantages of merely contacting each other during assembly are achieved without the need for structural changes to the supporting structure of the solar module.

The contact element, in particular the double profile element can be arranged over the entire length of the solar modules or also extend beyond in the direction of adjacent solar module assemblies, in a variant, the contact element may be limited to the area of the support structure alone.

Preferably, wherein the abutment element have two receiving areas arranged at an angle to each other. In this variant, each receiving area can have a lower and upper leg, wherein the lower leg is longer. This simplifies the assembly.

The object of the invention is likewise achieved with the solar module arrangement according to claim 10. This solar module arrangement, which corresponds in particular according to the solar module arrangements as described above, is characterized in that the support structure has a bottom plate towards the lower edge of an active area. The bottom plate allows for safe installation of the modules on the flat roof. According to a preferred embodiment, the bottom plate may be formed integrally with the support structure. This reduces the number of components used for the flat roof construction.

According to a variant, however, the bottom plate can be releasably fastened to the support structure, wherein in particular no further elements between support structure and bottom plate are used.

According to another variant, the angle between the surface normal of the bottom plate and the surface normal of the active region may be adjustable within a predetermined range. Due to the direct connection of the support structure to the bottom plate, the number of elements used can be reduced compared to the prior art. The adjustability of the angle allows the adjustment of the installation to unevenness on the flat roof or the orientation of the modules.

Particularly preferably, the bottom plate may be made of plastic. This reduces the weight of the substructure.

According to a preferred embodiment, the bottom plate can have two receiving areas for two different modules, in particular for the two modules arranged at an angle to one another. In particular, in the case of two angularly arranged modules, the use of the bottom plate allows on the one hand the desired displacement safety of the solar module assembly while on the other hand, the orientation of the modules can be specified by the two receiving areas. As a result, it is possible in particular to dispense with the pull rod or the pull rope.

According to a variant, such a base plate can also be used only between two different rows of solar module arrangements according to the invention in order to ensure the distance between two solar module arrangements. However, it is particularly according to the invention, if the attachment of the support structure takes place on the bottom plate without the interposition of other connectors.

Alternatively, the distance can also be ensured by means of a spacing means spaced from the floor, in particular a bar which is either fastened to the supporting constructions or fixed to the floor panel.

The object of the invention is further achieved with a solar module arrangement according to claim 15. This can in particular be designed as described above. The solar module arrangement comprises two angularly arranged to each other solar modules, each solar module having an active area for the conversion of solar energy and an active area fixed support structure, in particular rear side disposed in the active area, wherein the two supporting structures supported in the region of their facing upper ends of a supporting construction be, characterized in that each support structure is connected via a pull rope or a tie rod with the support structure.

In contrast to the connection of the two solar modules via a single continuous pull rod or a single continuous pull rope, according to the invention, the pull rope or the tie rod split and causes a connection of the support structure with only the support structure. As a result, for example, at the edge of a flat roof when space reasons, no double arrangement is possible without having to use other elements, only a half row with solar modules can be realized. The second solar module normally provided at an angle to the installed solar module can then simply be omitted.

Particularly preferably, the traction cable or the drawbar can be arranged on a region remote from the upper edges. This achieves a good stability of the overall construction.

According to an embodiment of the invention, each module may have two supporting structures in the form of mutually parallel, substantially extending from edge to edge struts. These are usually made of metal, for example, stainless steel and preferably have in the edge region on end portions which do not rest against the active area, but extend to the edge of the module.

The invention also relates to a solar module which is designed for a solar module arrangement according to one of the above claims.

The invention likewise relates to a carrier plate for connecting a first solar module arrangement with solar modules arranged at an angle to one another with a second solar module arrangement, in particular for solar module arrangements as described above, with a base plate and at least one first and at least one second module support element, wherein the at least one first module support element for laying a Support structure of a solar module of the first solar module assembly and the at least one second module support member for laying a support structure of a solar module of the second solar module assembly is provided. With this carrier plate, the assembly process is greatly simplified because the modules can only be hung from above. On introducing additional fasteners can be completely dispensed with

Preferably, the base plate and the at least one first and the at least one second module support element can be integrally formed. This reduces the number of components required for assembly.

Advantageously, each module support element can have a module support region running obliquely to the base plate. Due to the inclined support area, the mounting angle of the module is specified. This can possibly be adjustable.

According to a preferred embodiment, at least one, preferably two, holding element (s), in particular a spring element or a split pin, can be arranged on each module support region, wherein the holding element is designed such that in the assembled state the holding element is inserted into a groove in the support structure of the assembled one Solar module engages. This prevents lifting of the module despite the simplified installation.

Preferably, carrier plate can be formed below a module support surface of the module support elements, a channel for receiving a pull rope or a pull rod. This further simplifies assembly, as access to the channel is easier to access than attachment to the support structure of the modules.

More preferably, the channel can be formed horizontally and widening. An outwardly widening channel has the advantage that slight displacements of the modules against each other do not lead to unnecessary tension on the pull rope or the tie rod.

According to a preferred embodiment, the pull rope or the pull rod can be detachably fastened in the channel, in particular via a bayonet catch or a screw connection. As a result, the entire structure gains in strength.

Advantageously, the carrier plate may have at least two parallel aligned carrier elements, which are connected to each other via at least one spacer element, wherein each carrier element has two module support elements. Thus, the individual components can be kept small, which simplifies the transport. The invention also relates to a method for assembling a first solar module arrangement with solar modules arranged at an angle to one another with a second solar module arrangement, in particular for solar module arrangements as described above, on a carrier plate according to the invention, comprising the steps of: a) lowering a first solar module of the first solar module arrangement to a first module support element of the support plate, wherein an end region of a support structure of the first solar module comes to lie on a module support region extending obliquely to a base plate of the first module support element and b) lowering a second solar module of the second solar module assembly on a second module support element of the support plate, wherein an end portion of a Supporting structure of the second solar module comes to rest on an inclined to a base plate module support area of the first module support element. This reduces the number of assembly steps.

Hereinafter, embodiments of the invention for further explanation of the invention will be described in detail.

Figures 8a-8b show a sixth embodiment of the invention, and

FIGS. 9a-9b show an inventive method of assembling solar modules.

FIG. 1 shows a first embodiment according to the invention of a solar module arrangement 1 with two solar modules 3 and 5 arranged at an angle to one another, which are arranged on a base surface 5, for example a flat roof. In this embodiment, the two solar modules 3a and 3b are so-called thin-film solar modules having an active region 7a and 7b each composed of a front glass 9a, 9b, an active layer 11a, 11b and a back glass 13a, 13b. According to further variants, further layers, for example reflective layers etc., may also be provided in the active region. The solar modules 3a and 3b shown here are used to convert solar energy into electrical energy, but alternatively, the solar modules could also relate to modules that are used to obtain heat energy, for example, for heating water.

On the back of the solar modules 3a, 3b, that is arranged on the surface of the rear glass 13a, 13b, there is a support structure 15a, 15b. According to the invention, the two supporting structures 15a, 15b abut one another in the region of their mutually facing, upper ends 17a, 17b only without coupling. In order to enlarge the contact surface, the supporting structure 15a, 15b has a bearing plate 19a, 19b at this upper end 17a, 17b. The bearing plates 19a, 19b are integrally formed with the support structure 15a, 15b in this embodiment. Alternatively, however, these could also be screwed to the support structure 15a, 15b, infected or connected in any other way with this. In the multi-piece variant, the elements can also be arranged against each other so that the angle between the support structure and bearing plate can be adjusted.

Towards the base 5, the supporting structures 15a, 15b each have a bottom plate 21a, 21b. In this embodiment, this is formed integrally with the supporting structure 15a, 15b. Alternatively, however, a separate bottom plate element could also be inserted, screwed on or fastened in any other way to the supporting structure 15a, 15b.

In order to ensure the angular alignment of the solar modules 3a, 3b, a pull cable 25 or alternatively a pull rod is used on mounting holes 23a and 23b provided in the support structures 15a and 15b.

Due to the torsional rigidity of the supporting structure 15a, 15b, moreover, no further connection of the two modules needs to be provided.

According to a variant, however, in order to prevent unwanted displacement of the two modules relative to one another perpendicular to the plane of the drawing, the surface of the contact plates can be roughened. This is indicated in Fig. 1 by reference numeral 27. Alternatively, a corresponding coating on the contact plate 19a, 19b, for example, an elastic be provided plastic table layer. A shift perpendicular to the plane of the drawing could also be prevented by a form fit.

The support structure 15 a, 15 b together with the contact plate 19 a and the bottom plate 21 a is preferably metallic, in particular made of stainless steel or aluminum. In the multi-part variants, the contact plate and / or the bottom plate can also be made of plastic.

FIG. 2 shows a second embodiment of the solar module arrangement 31 according to the invention. In turn, the two solar modules 3a and 3b are shown, the construction of which is not explained in detail here again and reference is made only to the description made above. The two solar modules 3a and 3b have a modified support structure 33a and 33b without the abutment plates 19a, 19b and without the bottom plates 21a, 21b. In this embodiment, the upper ends of the two support structures 33a and 33b are again abutted against one another via a contact element 35. An additional connection of the two supporting structures 33a and 33b in the ridge area is not necessary. A shift perpendicular to the plane can be prevented by positive locking.

The structure of the contact element 35 is the known double-profile elements, which are used in mounting on pitched roofs to attach two juxtaposed rows of solar modules to a profile, ajar. In order to achieve the angled arrangement, the double profile element is bent and thus has two receiving areas 37 and 39 arranged at an angle to one another. Here are the end portions 41 a, 41 b of the support structure 33 a and 33 b on the lower legs 43 and 45 of the receiving areas 37 and 39. The legs 43 and 45 are designed to be longer than the upper legs 47, 49, which together with the lower legs 43 and 45, the receiving areas 37 and 39 form. This embodiment thus has the advantage that modules 3a, 3b can be used whose support structure 33a, 33b correspond to the supporting structures which are also used during assembly in normal double profile elements.

The normal double profile rail is thus replaced only by an angled double profile element. In this case, the double profile element 35 may also be formed as a rail, so that a plurality of solar module pairs can be placed side by side on a rail or it may be provided for a module pair 3a, 3b, a contact element 35 or even in the presence of multiple supporting structures per active area, for example, in the presence of two mutually parallel supporting structures, so-called. Backbars, be provided per support structure, a contact element in the form of an angled double profile piece. The second embodiment of the solar module arrangement according to the invention also differs in the contact area of the two modules 3a, 3b on the base 5. Instead of bottom plates 21a, 21b (see Fig. 1) to use here are the end portions 47a and 47b of the two supporting structures 3a and 3b in Receiving openings of a bottom plate 49, which rests on the base 5, inserted. In this case, use is made of the projecting property of the end regions 47a and 47b of the supporting construction, whose ends, although they are flush with the edges of the active region, are spaced therefrom.

The bottom plate 49 thus fixes on the one hand the angled arrangement of the two solar modules 3a and 3b and on the other hand due to the friction between the trough 49 and the base 5 prevent migration of the solar module assembly on the base.

The bottom plate 49 is shown schematically in a three-dimensional view in FIG. At the angle with respect to the base plate 51 arranged side walls 53 and 55 receiving openings 57 and 59 are provided. In these receiving openings 57 and 59, the described end portions 47a and 47b are inserted.

According to a preferred variant, the side walls 53 and 55 may be arranged on the base plate 51 such that the angle 61 between the side wall 53 and the bottom plate 511 can be adjusted. As a result, the two solar modules 3a and 3b arranged at an angle to one another can be aligned with different angles relative to one another. For this purpose, then only one contact element 35 must be provided with a corresponding angle.

On the side walls 53 and 55 may further fastening openings 61 a, b, c and d may be provided.

As shown in FIG. 2, a connecting element 65, in the form of a rod, can be fastened to these fastening holes 63a to 63d. A second trough 49 of an adjacent solar module arrangement can then be attached to this connection element 65. In this embodiment, the spacer 65 is not on the base 5 on. You may also be able to use a rope here.

The bottom plate 49 may be made of metal or plastic.

According to further variants, the trough 49 on the side walls 53, 55 may also have a plurality of recesses in order to be able to receive the end regions of adjacent solar modules, whereby a connection of adjacent solar module arrangements is made possible. In the presence of multiple support structures 33a and 33b per active area, these can also be inserted into the recesses of a single tub. Thanks to the torsional rigidity of the supporting structure and the presence of the trough, here too a concern in the upper of the supporting structures is sufficient to allow the stability of the arrangement. If necessary, one or more additional support structures may also be provided between the modules in the mounting holes 23a to 23d.

The individual elements of the first and second embodiments can be combined with each other as desired. Thus, for example, in the second embodiment, instead of the abutment elements 35, the abutment plate, formed in one piece or in several pieces, can be used.

FIG. 4 shows a third embodiment of the invention.

Elements with reference numerals which have already been used in FIGS. 1 to 3 will not be described in detail, an explanation is hereby made. Also in this embodiment, two solar modules 3a and 3b with their support structure 33a and 33b are arranged at an angle to each other. The end portions 41a and 41b of the support structure 33a and 33b are supported by a support structure 71 in this embodiment. Here are the end portions 41 a, 41 b, which are shown in dashed lines, each in a U-shaped portion of the support structure 71. By means of a pin 75a or 75b, the support structure can be connected to the support structures via the mounting holes in the support structure.

According to an alternative, the abutment elements 73a and 73b may also be designed to be movable with respect to the supporting construction 71 in order to achieve a certain degree of flexibility in alignment. Instead of inserting the end portions 41a and 41b in a U-shaped profile, a plug connection or a screw connection can be provided over smooth contact surfaces.

According to the invention, a pull rope or a pull rod is also used in this embodiment, but the pull rope is designed in several parts. Thus, the support structure 33a of the module 3a is connected via a first pull cable 77 to the support structure 71 and a second pull cable 79 serves to connect the second module 3b also with the Abstützkonstruktion 71. This can, for example, at the edge of the flat roof, if no complete solar module assembly with two Modules can be built more, without changing the mounting elements used only one of the two modules, for example 3a together with support structures 71 and the pull cable 77 are used. This is indicated schematically in FIG. In this embodiment, the base areas 5 facing end portions 47a and 47b of the solar design 33a and 33b bottom plates 80a and 80b are inserted. By inserting can be dispensed with the use of additional elements such as additional angle connector. The base plates 80a may be made of metal or plastic roughened on their sides facing the base 5 sides or have other anti-slip. Particularly preferably, such a base plate is used for each end region of a supporting structure.

FIG. 6 shows a fourth embodiment according to the invention with two solar modules 3a and 3b arranged at an angle to one another, whose supporting structures 33a and 33b engage bottom plates 80a and 80b with their lower end regions 47a and 47b and which in turn via a support structure 81 in the upper end region of the supporting structure 41a and 41st b be supported. The upper end portion 41 a and 41 b are only abut each other via abutment elements 83a and 83b. The two contact elements 83a and 83b rest on the support structure 81. As in the embodiment of FIG. 4, two pull ropes 77 and 79 are used. On a more detailed explanation of the elements with reference numerals which have already been used in previous figures is omitted and refer to the detailed description.

The embodiments 1 to 4 of the solar module arrangements according to the invention have in common that a coupling of the solar modules in the ridge area as used in the prior art is also dispensed with. The solar modules are only on each other, which greatly simplifies the installation. So it is sufficient for the assembly, the two solar modules only to put together and then attach the pull ropes or the bottom plate. If a more extensive support structure is desired, the support structure according to the invention can be used with the two-part pull ropes / tie rods, as described in the third and fourth embodiment. Possibly, a frictional or positive fit may be provided to prevent the displacement perpendicular to the plane of the drawing.

FIG. 7 a shows a fifth embodiment according to the invention with a first solar module 3 b of a first angled solar module arrangement 101 and a second solar module 3 a of a second angled solar module arrangement 103, which are connected to one another via a carrier plate 105. This carrier plate replaces, for example, the connecting element 65 of the second embodiment.

FIG. 7b shows a schematic three-dimensional view of the carrier plate 105. The carrier plate 105 comprises a base plate 107 and four module support elements 109a, 109d, the module support elements 109a and 09b for placing the module 3a and the module support elements. te 109c and 109d for placing the module 3b are provided. Optionally, an adjacent module may be placed on the element 109b to module 3a and likewise may be placed on the element 109d, an adjacent module to module 3b.

The module support elements 109a to 109d are preferably formed integrally with the base plate 107. For example, these are riveted to the base plate 107 or otherwise firmly inseparably connected before assembly otherwise.

Each module support element comprises a module support region 111a to 111d which runs obliquely to the base plate 107 and onto which the respectively associated end region 47a or 47b of the support structure 33a or 33b can be placed from above. In order to prevent unintentional lifting of the modules, a spring element 113c, 13c 'and 113d, 113d' are provided on the support area on the right and left, which are also provided on the right module support elements 109a and 109b, where, however, only one is shown in the illustration Spring element 113a and 113b can be seen. In this embodiment, the angle is fixed, possibly according to a variant of the support area with respect to an adjustable angle. The base plate 107 may be formed in order to enable different Aufständerungswinkel.

When placing the supporting structures 47b snap the spring elements 113c, 113c ', 113d, 113d' etc, in designated grooves 115 in the end portions 47a, 47b of the supporting structures 33a and 33b. Instead of spring elements and other fastening means, such as a pin, sapwood or similar component can be used to prevent lifting.

Figure 8a shows a sixth embodiment of the invention in a schematic cross-sectional view. FIG. 8a again shows a solar module 3b of a first angled solar module arrangement 101 and a second solar module 3a of a second angled solar module arrangement 103, which are connected to one another via a carrier element 151. This support member 151 replaces the support plate 105 of the fifth embodiment.

The carrier element 151 comprises a center piece 153 and towards the ends in each case an integrally formed with the middle piece module support member 155a, 155b is formed. In this case, the module support elements 155a for placing the module 3a and the module support element 155b for placing the module 3b is provided. Underneath the module support surfaces 157a and 157b of the module support elements 155a and 155b, a channel 159a and 159b extending essentially horizontally is formed. The channel 159a widens perpendicular to the plane of representation outward in the direction A away from the centerpiece 153 out. Likewise, the channel 159b widens outwardly in the direction B away from the centerpiece 153 out. The two channels 159a and 159b are axially aligned.

The channels 159a and 159b each serve to receive a traction cable 25 or a drawbar which, unlike the first embodiment, is thus not fastened directly to the modules themselves. The channels could, according to a variant along their longitudinal extent, for example, be downwardly open to facilitate the insertion of the pull cable 25 or the rod.

The pull cable or the pull rod 25 may be fixed in the channel, for example by the use of a bayonet or screw on the pull cable 25 or the pull rod and the respective channel 159a and 159b.

The use of a widening channel eases the alignment requirements of two modules of a module assembly since the traction cable 25 can follow deviations in orientation in the channel.

The end portions 47a and 47b of the two support structures of the modules 3a and 3b are mounted on the module support surfaces 157a and 157b and can be displaced perpendicular to the plane of the drawing by laterally elevated side walls 161a and 161b in front of and behind at least a portion of the end portions 47a and 47b be prevented. Lifting is, as in the fifth embodiment, via a spring element automatically snaps into grooves in the end portion 47 a and 47 b or as shown here via a pin or cotter pin 163 a and 163 b prevented.

As shown in FIG. 8b in a schematic plan view, two parallelly oriented carrier elements 151 can be connected to one another via a spacer element 171 and thus form a carrier plate on which a support structure of four different solar modules can be placed at the positions 173, 175, 177 and 179. Eventually, more than two parallel aligned carrier elements can be connected to one another via one or more spacer elements 71. Dotted lines are the channels 159a and 159b, which expand in each case to the outside.

FIG. 8b likewise shows the sectional plane CC, which corresponds to the view of FIG. 8a. The fifth and sixth embodiments of the invention enables further simplification of assembly. Thus, as shown schematically in FIGS. 9a and 9b, the carrier plate 105 with the integrated support elements 109a to 109d is placed on the base 5, the modules 3a and 3b to be mounted are placed on the module support region 111a from above with the support structures 33a and 33b and 111 c and makes snap the spring elements 113 a, 113 c in the grooves provided 121 a and 121 b.

On a cumbersome insertion of its own additional connector element in a hollow chamber of a carrier profile and the subsequent mounting of the connector to a bottom plate can be omitted.

The fifth and sixth embodiments of the invention can also be combined with the different variants in the ridge area but also with the variant of the support of the period. However, the carrier plate according to the invention enables the improvement of the assembly process even in embodiments in which it comes in the ridge area to a coupling. The variants according to the invention described in the various embodiments in the ridge region of the solar modules can be arbitrarily combined with the different variants in the floor area.
