Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a solar module support device according to the preamble of claim 1 for holding solar modules over base surfaces in the form of roof surfaces or other free surfaces, which surfaces are not inclined or only slightly, for example a maximum of 15 °.

[0002] The solar module support devices are used to optimize the solar incident on the surface of the solar modules. The surface of a solar module facing the sun during the energy production of the sun runs at an angle to a horizontal plane after mounting on the solar module support device. The solar module support device defines a front, rear and two lateral edge lines forming a rectangle. Along or optionally within this rectangle, the solar module support device comprises support areas for supporting surfaces, in particular frame sections, of the solar module. The front line of the solar module supporting device is usually located as a lower line less far than the roof or free surface than the front or upper line opposite the front line.

[0003] For fixed solar modules, the lower line is oriented such that at a desired time in the course of the day a line perpendicular to the lower line can be aligned with the sun. The inclination of the plane with the support regions for a solar module is preferably selected as a function of the degree of latitude of the site and, depending on the orientation of the lower line. If the solar modules are intended to be particularly well directed towards the sun at noon, the lower and upper lines extend essentially in the east-west direction. If the solar modules in the morning and in the afternoon are particularly well directed towards the sun, the lower and upper lines extend essentially in the north-south direction. It goes without saying,

[0004] There are areas on which first solar modules in the morning and second solar modules in the afternoon are to be optimally aligned. For this purpose, it is expedient for the solar modules, which adjoin one another in the east-west direction, to be divergent to the east and the west to the east, and the surfaces of the solar modules alternately rising and falling.

[0005] The widespread solar module support devices extend from horizontally extending profiles laid in a grid arrangement, over which inclined profiles are fastened with the desired inclination, wherein, for example, vertical profiles extend from the horizontal profiles to the upper lines and there with the inclined profiles are connected. The profiles are relatively expensive to manufacture and the connections between profiles include screws and / or rivets. In the transport and construction of such profile solutions, the space requirement or workload is very large.

[0006] Solutions are known from WO 2013/186 217 A2, DE 20 2009 007 481 U1, DE 10 2010 01 369 A1 and DE 10 2012 108 138 A1, which use parts formed from sheet metal blanks. From horizontally extending sheet metal areas, longer, upstanding sheet metal areas lead to the upper line on the one side and shorter sheet metal areas on the other side to the lower line. The upwardly extending sheet metal regions extend in planes parallel to the upper line and are not dimensionally stable with respect to the force effects perpendicular to the upper line. In order to achieve the necessary stability, large sheet thicknesses and / or additional reinforcing elements must be used, which is associated with increased material and machining effort.

[0007] WO 2013/153 200 A2 describes a holding device with pairs of U-shaped horizontal rails, U-shaped inclined supporting legs extending from the rails under the solar module, and U-shaped supporting legs leading from the rail to the upper end of the supporting legs , The connecting bolts between the interconnected U-shaped parts and their bearings are subjected to high loads. For mounting the solar modules, the support legs each comprise two suspension devices. The distance between the two suspension devices of a support leg is adapted to the corresponding length of the solar module. Because the solar modules of different manufacturers have slightly different lengths, different support legs have to be produced and selected correctly. Because the solar modules are only suspended, undesired vibrations between the solar modules and the support legs can occur at high wind speeds. Wind-induced vibrations can also occur between the supporting legs, the supporting legs and the rails and can cause undesirable wear during the bearing arrangements of the connecting bolts.

[0008] DE 10 2014 106 800 A1 describes a further holding device with pairs of U-shaped, horizontal rails. On each rail, two separate stands are arranged per solar module, one leading to the lower line and the other to the upper line. Each solar module is connected to the upper end of a stand at the four corners. The stands are U-shaped from sheet metal parts, their free ends being connected to the solar module and their lower connecting surfaces being connected to a respective rail. The forces generated at the solar modules must be absorbed by the four narrowly limited connecting areas between the solar modules and the stands. In order to achieve the necessary stability, large sheet metal thicknesses and / or complex bending formings with double U-legs must be used for the stands,

[0009] The use of long, U-shaped rails in the cross-section can lead to problems with uneven roof surfaces or free surfaces, since these rails then rest only at individual points and, if necessary, deform due to high local loads. The U-shaped rails and legs or legs known from the state of the art need a lot of space during transport and must be assembled with a great amount of assembly effort. In addition, the length of the rails must be adapted to the size of the area to be covered with solar modules.

[0010] The object according to the invention is to find a simple, efficient and stable solar module supporting device.

[0011] The object is achieved by the features of patent claim 1. The dependent patent claims describe alternative and / or advantageous design variants which solve further tasks.

In an inventive step, it was recognized that, in the case of a solar module supporting device to be arranged on a base surface, the production and assembly effort can be reduced and the stability can be increased if the solar module carrying device has at least two carrier devices arranged parallel to one another at a distance from one another Each comprise a pair of side surfaces which extend side by side from the base surface to a support area. Both side surfaces of a supporting device each terminate at their lower end via a lower bending area into a standing surface and at the upper end over an upper bending area into the supporting area, which preferably slopes to the horizontal plane and therefore runs ramp-shaped. An acute angle corresponding to the desired inclination of the solar module to be supported is formed between the longitudinal orientations of the lower and upper bending areas of each side surface. It goes without saying that this angle can also be 0 °, for example if the base surface is already inclined, or if no inclination is desired at all. The supporting area is formed between the two upper bending areas of a side-face pair. The side surfaces extend along the longitudinal axis of the support means. The supporting area is formed between the two upper bending areas of a side-face pair. The side surfaces extend along the longitudinal axis of the support means. The supporting area is formed between the two upper bending areas of a side-face pair. The side surfaces extend along the longitudinal axis of the support means.

At the lower bending regions, first connecting elements are formed, with which suitable second connecting elements of spacers, preferably spacer plates, and in particular also spacer strips, can be detachably connected. It goes without saying that the connection between a first and a second connecting element can also be achieved via a further element. In the mounted state of the solar module supporting device, at least one spacer or a spacer extends transversely to the longitudinal direction of two supporting devices running side by side at a distance. At both end regions of the spacer or of the spacer plate which are assigned to the supporting devices, or their facing lower bending regions, second connecting elements are formed,

[0014] As the first connecting elements, insertion openings which lead through the side surfaces of the support device are preferably used, the opening width being the smallest at the lower folding area. The opening width increases somewhat, in particular V-feed, slightly above the lower bending region or above the lower edge of the insertion openings. Preferably, projecting lugs are formed as corresponding second connecting elements, especially at the free end, which are somewhat wider than the smallest opening width of the insertion openings and have a narrowing at a small distance from the free end, Opening width of the insertion openings and the wall thickness there,

[0015] It goes without saying that the position and the configuration of the first and second connecting elements can also be varied. Thus, for example, the first connecting element could also be designed as parts projecting upwards from the supporting surfaces, in particular as cut-out and raised tabs, and the second connecting elements as corresponding openings in the spacing plates and spacing strips. If necessary, securing elements, for example cotter pins or spring plugs, are used to secure such connections, corresponding inlet openings then being necessary.

The first connecting elements are formed at uniform intervals along the supporting devices on both side surfaces so that a spacing plate and a supporting device can be arranged transversely to the carrying devices again and again until a desired region of the base surface is covered in this direction. In order to be able to position the carrier devices adjoining in the longitudinal direction of the supporting devices at desired intervals, second connecting elements of a spacer plate or a spacer strip connecting them are inserted into first connecting elements of successive carrying devices in the longitudinal direction. A spacing strip merely connects supporting elements of one side to one another. A spacer plate can be designed and used in such a way that,

For the grid-shaped arrangement of the supporting devices, no long profile rails and also no other long elements are required, which extend over expansions of several solar modules and are therefore bulky and not adapted to irregularities of the base area. The maximum expansions of the supporting devices, the spacer plates and the spacing strips all correspond approximately to the greatest dimensions of the solar modules used. Compared to solutions with long profiles, this results in facilitated material transport and easier assembly. Ground surfaces with irregular edge lines can also be optimally covered with solar modules.

If the fixation of the solar module support device is to be achieved with gravel or other bulk material or other ballast systems, such as panels, the support devices, the spacer plates and, if appropriate, the spacer strips are constructed on the uncovered base surface. Subsequently, gravel, other bulk material or ballast is applied in the form of piece goods in such a way that the spacing plates and, if appropriate, the spacing strips are sufficiently covered. The assembly of the solar modules takes place only after the application of the ballasting.

The length of the spacing plate between the end regions with the second connecting elements determines the distance between the adjacent supporting devices. In order to ensure a space required for supporting a specific solar module, only the corresponding spacer plate has to be selected and used.

[0020] In a preferred embodiment, the carrying devices are designed in such a way that they can be stacked for transport. In order to obtain a stackable solution, it would be possible to allow the two side surfaces of a support device to diverge slightly from the support area towards the support surfaces, so that the regions of the side surfaces, slightly V-shaped towards the open end, allowed. In preferred solutions, the shaping would be chosen such that the two lower bending regions still run parallel. For this purpose, either the width of the supporting area or the expansion angle should increase from the higher towards the lower end of the ramp-shaped support area.

The disadvantage of such single-part stackable support devices is that weight forces transmitted in the oblique side surfaces can lead to deformation of the lateral surfaces, the deformations being able to be counteracted with stabilizing shaping elements, in particular beads, in the side surfaces.

[0022] In a further preferred embodiment, the stackability and stability are further improved by the support devices each being composed of two parts which are Z-shaped in cross-section. The two parts each comprise a side face which extends from the base surface to a ramp-shaped supporting region on an inclined line. The side surfaces of both parts of the carrying device each terminate at their lower end over a lower bending area into a standing surface and at the upper end over an upper bending area into a respective ramp-shaped supporting area, these Z shapes of the two parts having to be essentially mirror image-shaped. An acute angle is formed between the longitudinal orientations of the lower and upper bending areas of each side face, Which corresponds to the desired inclination of the solar module to be supported. When assembling the two-piece support, the support portions of the two members are abutted against each other, and the side surfaces of the two members extend along parallel vertical planes.

The transfer of force from the support regions via the side surfaces to the base surface does not lead to deformations of the side surfaces, in particular if the stability of the side surfaces with structural elements, in particular beads, is still increased. When the lower bending areas or the supporting surfaces of a supporting device are moved apart, they are prevented from being moved towards the adjacent support means by the spacer plates. The side of a support device, which is not followed by any further support means, is not heavily loaded because only one solar module rests on the last support device.

In order to ensure that the two parts assembled to form a supporting device remain in the desired position, third and fourth mutually matched connecting elements are brought into connection with the bearing regions which bear against one another. Preferably, the third connecting elements are formed by projecting tabs and the fourth connecting elements are formed by corresponding slots. It would be possible to form only slits in the support area of one part and only slots in the support area of the other part.

[0025] In a further preferred embodiment, the support regions are interrupted in a central region. One part is formed on one side of the interruption and third connecting elements are formed on the other. In the other part, the arrangement of the third and fourth connecting elements is selected just the other way round. The two parts can now be pushed into one another about an axis of rotation running perpendicular to their longitudinal axis in a slightly twisted orientation with the two interrupted central regions and are rotated in such a way that all third and fourth connecting elements engage one another and form a composite stable supporting device.

An embodiment with two-part support devices and spacer plates, as well as, if necessary, spacer strips, comprises, in the simplest form, only three or four different parts, all of which can be stacked very compactly. The cost of manufacturing these parts is also very small because all can be made from sheet metal blanks.

The two parts for carrying devices can thus be cut out of a large sheet metal in such a way that only a small edge area and small spacing areas between the parts remain unused. After cutting these parts and the openings, slots and cuts for tabs provided in the parts, only the tabs have to be bent and the folds have to be carried out on both sides of the side surfaces.

[0028] Forces acting transversely to the longitudinal axis of a support means could lead to a tilting deformation of the support means. In order to prevent this, in a special embodiment, a substantially vertically oriented stiffening plate can be used between two supporting devices, preferably at their end, in particular in the upper line. Instead of stiffening plates or in addition to this, similarly arranged wind shielding plates can be used, which reduce the entry of wind into the solar modules at lateral edges of a system with solar modules.

The support area of each support device is designed so wide that a solar module can be placed on both longitudinal edges, a narrow free space remaining between the solar modules. The fastening of the two solar modules lying next to one another on the support device preferably takes place together with fastening devices which press a retaining part from the top onto the frames of the two solar modules so that the frames of the modules are clamped between the support area and the holding part. In the case of each support region, such holding members are preferably arranged at two spaced-apart locations.

The screw with which a holding part is fastened is screwed into a nut, in particular a blind rivet nut, arranged underneath the supporting region. If a distance is formed between the underside of the holding part and the upper side of the supporting area, a distancing element, in particular a sleeve, can be inserted between the holding part and the supporting area. It goes without saying that the distancing belt can also be integrated in the holding part. Such a spacer sleeve prevents deformation of the tag area when the holding part is tightened.

[0031] In the case of carrying devices which are composed of two parts, the fastening devices are preferably designed such that they also press against one another the bearing regions of the two parts, thus increasing the stability of the assembled carrying device.

[0032] The solar modules must be connected to corresponding lines. In the case of photovoltaic modules, electrical connecting leads are routed in cable ducts from the connection points of each module to connecting points of the entire installation. In order to enable necessary cable guides, first cable ducts extending transversely to the longitudinal direction of the carrying devices are each fastened thereto in the middle region of two supporting devices arranged next to one another. The first cable ducts preferably have a substantially V-shaped cross-section, so that they can be stacked for transport. Furthermore, they comprise fastening regions for second cable channels, which extend in the longitudinal direction of the supporting devices between adjacent first cable channels. The second cable channels also have a cross-section,

[0033] In a preferred embodiment, a main channel is arranged along at least one lateral edge of a system with solar modules. Preferably, the main channel is at the feet, some of which are arranged on spacers. The position of the main channel can be secured by connecting these spacers to supporting means. The main channel is U-shaped or V-shaped in the cross-section and is covered on its upper open side with a lid, the cover and the channel comprising mutually adapted latching elements and preferably made of sheet metal. The main channel runs at the height with the connection openings to the first cable channels and has corresponding accesses for the cables to be carried through.

[0034] In a preferred embodiment, all the elements of the solar module support device 1 are positively connected to one another. Only the mounting of the solar modules is done with screw connections, for example with four screws per solar module. Only one screwing tool is required for the assembly.

FIG. 1 shows a solar module support device 1 for supporting 10 rectangular solar modules, which are not shown, which are arranged above a base surface in orientations of rectangles inclined opposite a horizontal plane. The rectangles which determine the orientation of the solar modules are formed by a lower, an upper and a two inclined lateral lines. The solar module support device comprises support devices 2 spaced apart from one another and extending along longitudinal axes, which are arranged in pairs in the case of inclined lateral lines of the alignment rectangles. Spacer plates 3 are arranged between the support devices 2 of one or two such pairs of support devices 2.

2 to 9 show details of the solar module support device 1. Each support device 2 comprises a pair of side surfaces 4 which extend along the longitudinal axis of the support device 2. The side surfaces 4 extend side by side from their lower end at the base area upwards to a ramp-shaped supporting area 5 at an inclined line of the alignment rectangle for a solar module. The side surfaces 4 each terminate at their lower end via a lower bending region 7 into a standing surface 6 and at the upper end via an upper bending region 8 into the ramp-shaped support region 5. An acute angle is formed between the longitudinal orientations of the lower and upper bending regions 7, 8. It goes without saying that this angle can also be 0 °,

In the case of the lower bending areas 7, first connecting elements 9 are preferably formed on the carrying devices 2, preferably in the form of insertion openings leading through the side surfaces 4 of the carrying device 2. The opening width of the insertion openings is the smallest at the lower bending area 7 and increases upwards, in particular V-shaped, over a section with a constant opening width.

The spacer plates 3 are preferably rectangular and, in the case of the side lines facing the support devices 2, comprise second connecting elements 10, which in the assembled state are detachably connected to first connecting elements 9 of the carrying devices 2. The second connecting elements 10 are designed as lugs protruding from the spacer plates 3, which at the free end are somewhat wider than the smallest opening width of the insertion openings and at a distance from the free end a constriction which adjoins the smallest opening width of the insertion openings and the wall thickness there Is adapted such that first and second connecting elements 9, 10 inserted into one another ensure positioning within a predetermined tolerance.

[0040] The shape and the arrangement of the spacer plates 3 are adapted to the desired ballast receptacle. If a lot of ballast has to be absorbed, plates with a large base area or several narrow adjacent spacing plates can be used. The first and second connecting elements are preferably designed so that two second connecting elements can be connected to a first connecting element. This allows an overlapping arrangement of the spacer plates.

When a mounted solar module transmits vertically upwardly directed forces to the supporting devices in the case of strong winds, a portion of these forces is transmitted to the ballasted spacer plate via first and second connecting elements 9, 10. In order to prevent undesired deformations of the spacer plate in regions with the second connecting elements 10, these regions can be reinforced against deformation, for example with shaped elements, in particular beads. In order that the entire spacer plates have a greater strength against the lifting forces introduced in the case of the second connecting elements 10, moldings, such as a fold-up fold-up region, can extend over the entire distance length of the spacer plates 3.

The solar module support device 1 comprises at least two spacer strips 11, which at a side line comprise second connecting elements 10, wherein the second connecting elements 10 of each spacer strip 11 are detachably connected to first connecting elements 9 of two supporting devices 2 adjoining one another along their longitudinal axes. If necessary, spacer plates 3 are used for connecting longitudinally adjacent supporting devices 2, as is illustrated, for example, in FIG. It goes without saying that the extent of the spacer plates 3 in the longitudinal direction of the support means 2 can also correspond to the length of the illustrated spacing strips 11, so that between carrying devices 2, Which are connected to one another via a spacer plate 3, spacings are provided. These distances allow access to the solar modules for control and maintenance work.

The first connecting elements 9 are formed at uniform intervals along the supporting devices 2 on both side surfaces 4, and the second connecting elements 10 of the spacer plates 3 and the spacing strips 11 are arranged at corresponding uniform intervals. In the illustrated embodiment, the spacer strips comprise three second connecting elements 10. The adjoining supporting devices 2 are spaced apart from one another in such a way that two second connecting elements 10 of the spacer strip 11 engage into first connecting elements 9 and the middle second connecting elements 10 of the spacing strip 11 is exposed.

The support devices 2 are arranged in parallel, arranged in a raster-like manner along two orthogonal directions, and in each orthogonal direction, only two support devices 2 are directly connected to each other via a spacer plate 3 or a spacer strip 11. As a result, the solar module support device easily adjusts to possible surface irregularities and no elements are used that are longer than the largest extent of the solar modules.

[0045] Forces acting transversely to the longitudinal axis of a support means 2 could lead to a tilting deformation of the support means. In order to prevent this, in a particular embodiment, a substantially vertically oriented stiffening plate 30 can be inserted between two support devices 2, preferably at their end, in particular outwards from the upper line. Instead of stiffening plates or in addition to this, similarly arranged wind protection plates 31 can also be used, which reduce the entry of wind into the solar modules during lateral edges of a system with solar modules.

[0046] The support means 2 are preferably each composed of two cross-sectionally Z-shaped parts 12,13, which each comprise a side surface 4, an upper Abkantbereich 8, a support portion 5, a lower Abkantbereich 7 and a standing surface. 6 The parts 12 and 13 are formed substantially mirror images of each other. So that the parts are held in a predetermined position on a supporting device 2 12 and 13 after assembling, they comprise at the abutting support portions 5 third and fourth, each adapted connecting elements 14 and 15. Preferably, the third connection features 14 of projecting tabs and the fourth connecting elements 15 formed by corresponding slots.

[0047] In the illustrated embodiment 5, the support portions of two assembled into a support device 2 parts 12, 13 in a central region of an interruption 16. When a part 12 16 14 third and fourth on the other side connection elements 15 are disposed on one side of the interruption. be the other part 13, the arrangement of the third and fourth connecting members 14,15 is reversed, so that the two parts 16 telescoped 12,13 to a direction perpendicular to its longitudinal axis of rotation in a slightly twisted position with the two interruptions and so rotated successively can that all third and fourth connecting members 14, 15 engage with each other.

[0048] In order to increase the stability of the lateral surfaces, these optionally comprise reinforcing structural elements 4a, in particular beads.

FIG. 7 shows that the parts 12 of the carrying devices 2 are stackable for transport. It goes without saying that the parts 13 can also be stacked accordingly. 10, the blanks 13 'for the parts 13 can be optimally cut out from a sheet, which is analogous to the blanks 12' of the parts 12.

[0050] In FIGS. 11 to 13, the installation of the solar modules 17 is shown. The support portions 5 of the support means 2 are formed so wide that both longitudinal edges of a solar module 17 can be placed. Between the solar modules 17, a narrow space is left free, clamped at least one frame of a solar module 17 between the support portion 5 and a holding member 19 in which at least one fastener 18th In supporting means 2, which are composed of two parts 12, 13, the fastening device 18 is preferably meadow formed so that it presses the support portions 5 of the two parts 12, 13 together and so increases the stability of the assembled support device. 2

In particular, the tabs 15 are positioned in such a way that the frame of a solar module 17 placed on the support device 2 or the parts 12 and 13 finds a stop in the tabs 15 and is prevented from slipping on the support regions 5 in the desired position , The positioning via the tabs 15 and the fastening with the fastening device 18 enable the mounting of solar modules 17 with different expansions along the carrier regions 5. The adaptation of the solar module support device 1 to solar modules 17 of different manufacturers with small size differences merely requires the selection of the corresponding spacer plate 3 ,

For fastening the holding part 19, the fastening device 18 comprises a screw 20 which is screwed into a thread, in particular a blind rivet nut, a cage nut or a thread in the sheet metal, which is connected to the support region 5 of the part 12. Between the underside of the holding part 19 and the upper side of the supporting area 5, a distance is formed in which a spacer sleeve 22 is arranged. Such a spacer sleeve 22 prevents a deformation of the support region 5 and / or the extraction of the nut when the holding part 19 is tightened.
