Description

The invention relates to a mounting system for mounting at least one solar module on a horizontal, in particular horizontal base with a substructure, which is designed to rest on the base, with a frame module which is mounted on the substructure, wherein the frame module interconnected cross braces and longitudinal struts and wherein the at least one solar module is attachable to the frame module. The invention also relates to a solar energy system with the mounting system.

Solar modules are used to convert solar energy into electrical energy and / or usable heat energy. So that a solar system is economically interesting, a large number of solar modules is used per solar system. The solar modules should be arranged angled relative to a horizontal, with an approximately 30 ° angle ensures maximum efficiency of the solar modules. From the boundary conditions with regard to the installation of the solar modules, there is thus the need to use a mounting system for receiving the solar modules.

Such mounting systems are widely known from the printed prior art. For example, the utility model describes DE 20 2008 000 528 U1 a solar module assembly for placement on a flat roof with an inclination of up to 30 °, which comprises a stator construction and a plurality of solar modules, wherein a solar module frame is provided, which has a recess as a feature for liquid in this document as a special feature.

The publication DE 20 2007 018 497 U1 on the other hand describes a device for mounting at least one solar module and a kit for their production, wherein a modular system is presented, which allows the arrangement of solar modules on pitched roofs.

The publication DE 20119629 U1 , which is probably the closest prior art, discloses a stand, in particular a roof rack, for photovoltaic and thermal modules with a frame of high-strength horizontal and vertical hollow body profiles, which are connected on the corner side and for receiving framed or unframed photovoltaic modules or thermal Solar modules are formed. In one embodiment, the module frame is mounted elevated on a horizontal base.

The invention has for its object to introduce a mounting system for solar modules, which opens up a high mounting flexibility. It is another object of the invention to provide a solar energy system with this mounting system.

This object is achieved by a mounting system with the features of claim 1 and by a solar energy system with the features of claim 14. Preferred or advantageous embodiments will become apparent from the dependent claims, the following description and the accompanying drawings.

According to the invention, a mounting system for mounting at least one solar module is presented. The solar module is preferably a photovoltaic module, which converts the light of the sun directly into electrical energy. Alternatively or additionally, the solar module can also be designed as a solar thermal module which converts solar energy into usable thermal energy, for example to support a heating circuit. The mounting system can optionally also be designed for mounting mixed types of solar modules.

The mounting system is designed to be placed on a horizontal, in particular horizontal footprint. In particular, the inclination of the footprint is less than 7 °, in particular less than 5 °. The footprint may be, for example, a flat roof of a building, such as a factory building or an office building. In particular, the flat roof on a conventional cover, the z. As bituminous sheets or other sealing layers. However, it is also possible that the mounting system - optionally with the interposition of a foundation o. Ä. - Is placed on a ground surface.

Preferably, the mounting system is designed to accommodate a plurality of solar modules, in particular at least three solar modules, preferably at least five solar modules and in particular at least seven solar modules in a row. In a large version, the mounting system can also be designed for more than 10, 20, 50 or 70 solar modules in a single row. Especially in this version, the mounting system for megawatt solar systems with a peak power of at least 1 megawatt peak power (1 MWp) is suitable.

The mounting system comprises a substructure, which is designed to rest on the base and a frame module, which is mounted on the substructure. Functionally, the mounting system is thus formed from at least or exactly the two subassembly and frame module assemblies.

The frame module has interconnected transverse struts and longitudinal struts, wherein the at least one solar module is attachable to the frame module and / or is attached. The transverse struts and longitudinal struts are preferably aligned at right angles or substantially at right angles to each other. Preferably, the solar module is based solely on the frame module on the substructure.

In the context of the invention, it is proposed that the transverse struts and the longitudinal struts of the frame module are displaceable relative to each other and / or positioned at different positions to each other, so that the frame module is adjustable, in particular adaptable to different sizes of different solar modules. It can be provided that the transverse struts and longitudinal struts are positioned to each other in stepped positions and / or are continuously displaceable.

In the most general embodiment of the invention, it is possible that the longitudinal struts are displaceable stationary to the substructure and the cross braces or the cross braces mounted stationary to the substructure and the longitudinal struts are displaceable or that transverse struts and longitudinal struts are both displaceable or positionable relative to the substructure.

The invention is based on the consideration that known mounting systems, in particular for flat roofs, are usually designed only for a single size of a solar module. Thus, the user is bound to a specific type of solar module in the selection of the mounting system, which represents an unreasonable restriction in the design of a solar energy system. For this reason, in the mounting system according to the invention, at least one setting possibility for adapting the mounting system to different sizes of different solar modules is provided.

It is optionally also possible that both photovoltaic modules and solar thermal modules are used in the mounting system, since the frame module is adjusted accordingly.

Thus, a universally applicable mounting system is proposed, which shows a high modulo variance, in particular solar module variance.

In a preferred embodiment of the invention, the top of the solar module in the intended position, ie the side with the active surface, opposite the standing surface by at least 14 °, preferably set up by at least 18 ° and in particular by at least 24 °. Preferably, however, the angle is less than 30 °, otherwise problems with respect to occurring wind loads and / or approval problems with regard to the applicable wind loads in accordance with DIN 1055/4 to be feared.

In a preferred development of the invention, the transverse struts and / or the longitudinal struts are designed as hollow profiles, in particular aluminum extruded profiles. Aluminum extruded profiles are characterized by a very high rigidity and low weight, so that the mounting system has a high mechanical strength and relatively low weight. Furthermore, the. in aluminum extrusions easy way to cut and assemble.

Preferably, the extruded aluminum profiles show grooves, in particular longitudinal grooves, into which sliding blocks or other elements can be inserted in order to fix fastening means for fastening the longitudinal struts and / or transverse struts to the substructure and / or to the solar module and / or one another. Instead of grooves, other mechanical interfaces such. B. through holes, blind holes, bolts, tapped holes, etc. may be provided.

In a preferred embodiment of the invention, the transverse struts are rectified to the standing surface, ie in particular aligned parallel to the standing surface, and the longitudinal struts angled aligned to the standing surface, in particular take the longitudinal struts the above-described intermediate angle between the base and top of the solar module.

Particularly preferably, the longitudinal struts are arranged displaceably on the transverse struts, so that the frame module can be adjusted to different widths of different solar modules. The width of the solar module is preferably understood to mean its extent in the direction of a row of the solar modules. When designing a solar energy system thus the cross struts are made up to the length, which - possibly taking into account gaps, etc. - corresponds to a multiple of the width of the solar module to be mounted. Thus, the mounting system is easily adaptable to different widths of solar modules without having to stockpile a large number of individual components. Alternatively, only a length of cross struts can be stored, with remaining free areas of the cross struts z. B. edge can be covered by a trim panel.

In a preferred development of the invention, fastening means for attaching the solar module to the frame module are provided, which are arranged on the longitudinal struts and displaceable along the longitudinal struts and / or can be positioned to adjust the frame module to different lengths of different solar modules can.

More specifically, not only the adjustability to different lengths but in particular the adjustability to different positions of the mechanical interfaces on the solar modules is a possible advantage of the invention. It has been shown that different solar module manufacturers indicate different positions on a frame of a solar module as a specified mechanical interface. Due to the displaceable and / or differently positionable fastening means on the longitudinal struts, it is possible to adapt the mounting system to the different lengths and / or to the different positions of the mechanical interfaces of the solar modules. Optionally, even with different solar modules with different thicknesses different fasteners can be stored and / or used.

In a particularly preferred embodiment of the invention, the substructure and the frame module form a self-supporting construction together and with the exclusion of the solar module. If, in particular, a cross-section perpendicular to the extension in the row direction of the mounting system is considered, substructures and frame module form a bridge or arch which is first assembled during assembly, stands independently and can then be fitted with the solar modules. This embodiment has the advantage that any loads that act on the mounting system, are not removed via the sensitive and expensive solar module. On the contrary, in the preferred embodiment of the invention, the solar module is mounted in the frame module made of extruded aluminum profiles, which are extremely stiff connection, so that no loads are introduced from the side of the mounting system in the solar module. The solar module is preferably supported linearly on the longitudinal struts and is fixed at the specified interfaces by the fastening means.

In a preferred constructive realization, the substructure is designed as a sheet metal construction, ie a construction in which the particular part and / or the supporting parts are made by sheet metal parts or are. In particular, the substructure has a front plate and / or a rear plate on which or on which the frame module, in particular the cross member, are fixed. Cross member and front plate and / or rear plate are thus rectified us / or aligned parallel to each other. In particular, the cross member are on the front panel and / or on the rear panel linear.

The front panel and / or the rear panel is formed in the preferred structural realization and / or arranged to remove the payload of the frame module in the direction of the footprint. In particular, the front panel and the rear panel support columns of self-supporting construction.

Particularly preferred front plate and / or rear plate in the surface extension formed continuously, so that no wind can penetrate into the mounting system. Wind can preferably flow only in the region of the module side surfaces in the mounting system for self-stabilization by suction and pressure regulation.

In one possible embodiment of the invention, the substructure has one or more support rails, which are designed to rest on the base and which extend continuously under the frame module. The support rails are thus rectified to a projection of the longitudinal struts on the surfaces and form surface and / or track-like conditions. In particular, the support rails transmit a linear load on the base surface, wherein the lines extend below the corresponding solar module. Due to this linear load, a greater distribution of the weight load on the standing surface is made possible so that even standing surfaces, in particular flat roofs with lower load capacities, can be built on with the mounting system.

Particularly preferably, the support rails are formed as sheet metal rails, which are at least partially folded over in the edge regions in order to obtain a structural rigidity.

In an advantageous embodiment of the invention, the front plate and / or the rear plate on the or the support rails, wherein the support rails are weakened in the support area compared to the rest of the support rails so that a deflection is made possible to approximate the support rails to a to allow uneven floor space. In the case of laterally folded support rails, it may be provided, for example, that the bends are interrupted in the contact area.

It is particularly preferred if the substructure and in particular the support rails are designed such that they can be set up ready for operation without damaging the standing surface, ie in particular without screwing, anchors, etc., with the support surface. In particular, the mounting system is placed on the stand surface without fixing. It is also particularly preferred if the mounting system is designed so that it allows a non-cutting and / or non-destructive mounting on the floor space. Especially with flat roofs, it is critical if they are drilled or otherwise damaged for the fixation of mounting systems, as this affects the tightness of the flat roofs. Here, the invention may have the advantage that it can be installed without a roof penetration, whereby it is particularly suitable for film, bitumen, silica and / or green roofs.

In the mounting system according to the invention, however, is preferably provided that this only rests on the base, but without being mechanically coupled with this in the opposite direction to the weight.

In an advantageous development slots or gaps are provided in the longitudinal extent of the transverse struts, which allow undercurrents of the solar module with wind. At a low end of the mounting system, a lower slot is provided, which extends if necessary. Interspersed by support feet between the support surface and the transverse strut. By spacing the lower slot of the solar module, the pollution of the space under the mounting system can be reduced. A gap-free or at least gap-poor transition between the solar module and the crossbar can be achieved on the one hand by an apron, which covers an existing gap. However, it is more preferable if the solar module on the crossbar on or even rests, so that a gap is avoided by the direct contact. In the implementation, it is preferred that at the low end the longitudinal struts in the form of a T-butt abut the transverse struts, in particular so that in this way a common bearing surface is formed and the gap-free transition is promoted. The lower slot has a vertically oriented opening surface, which has a height of preferably at least 20 mm, in particular at least 40 mm.

Another object of the invention relates to a solar energy system, with a plurality of rows formed as mounting systems, as described above or according to one of the preceding claims, wherein the rows are mechanically coupled to one another via the support rails. In particular, the mounting systems via the support rails are net-like and / or grid-like coupled together. For example, a matrix is formed with rows of mounting systems and columns of support rails. By linking the mounting systems ensures that even with stronger wind effects, the mounting system safely remains on the floor space, especially without being mechanically connected to this.

In summary, it should be noted that possible and optional advantages of the invention are achieved through the use of extruded aluminum profiles, the adjustability of the mounting system to the length and / or the width of different solar modules, so that solar modules with any format and any interface definitions are securely mounted can. It is also advantageous if, instead of point loads, line loads on the support rails, which are designed in particular as aluminum edge profiles, are removed onto the support surface. The support rails are particularly advantageously lined with building protection mats to protect the standing surface in the long term. Due to the structure of the mounting system chipless assembly and disassembly and thus repairability of both the mounting system and, if necessary. The flat roof is possible.

Further features, advantages and effects of the invention will become apparent from the following description of a preferred embodiment of the invention and the accompanying drawings. Showing:

Corresponding parts are each provided with corresponding reference numerals in the figures.

The 1 shows a schematic three-dimensional plan view of a solar energy system 1 as an embodiment of the invention. The solar energy system 1 is on a flat roof 2 sets up a horizontal or horizontal footprint for the solar energy system 1 forms.

The solar energy system 1 has three rows 3 each with four solar modules 4 on, which are designed as photovoltaic modules. The solar modules 4 are in the row 3 each arranged adjacent to each other with their narrow sides. The tops of the solar modules 4 are opposite the footprint of the flat roof 2 tilted by an intermediate angle alpha of about 15 ° to 20 ° in order to achieve high efficiency. The elevation of the solar modules 4 on the flat roof 2 via a mounting system 5 , which is explained in detail below.

The mounting system 5 is on the flat roof 2 , especially on its footprint, just hang up, in particular, are no destructive or damaging modifications, such as holes, etc. in the flat roof 2 perform. The mounting system 5 or the solar energy system 1 is solely due to the weight on the flat roof 2 held. The individual rows 3 of the mounting system 5 are over support rails 6 joined together so that the ranks 3 each other on the flat roof 2 hold tight.

The 2 shows a detail from the 1 , where the solar modules 4 are graphically suppressed. From this representation it can be seen that the mounting system 5 in a frame module 7 per row 3 and in a substructure 8th can be divided from sheet metal parts. The frame module 7 points per row 3 two parallel to the base extending cross struts 9 on, perpendicular to the cross struts 9 aligned longitudinal struts 10 are fixed. Every solar module 4 are two longitudinal struts 10 assigned. On the longitudinal struts 10 are fasteners 11 arranged for fixing the solar modules 4 serve. The fasteners 11 are designed as brackets that the solar modules 4 or hold their frame on the long side holding.

As synonymous in conjunction with the 3 which gives a slightly different perspective in top view of the frame module 7 shows are the longitudinal struts 10 along the cross struts 9 slidable on the cross braces, so that the distance B between two longitudinal struts 10 can be set variably. This makes it possible, even during assembly, the mounting system 5 to different widths of solar modules 4 adjust. The fasteners 11 are on the longitudinal struts 10 also arranged displaceable, so that also a length L for the solar modules 4 can be adjusted freely. The displaceability of the longitudinal struts 10 on the cross struts 9 or the fastener 11 on the longitudinal struts 10 can for example by T-grooves on the crossbars 9 or longitudinal struts 10 be ensured in the nuts are used. After setting the desired dimension for one of the solar modules 4 become the longitudinal struts 10 and the fasteners 11 fixed at the selected position by clamping, screwing etc.

The solar modules 4 lie only on the longitudinal struts 10 on. Because of the cross struts 9 and the longitudinal struts 10 are formed as extruded aluminum profiles, is the frame module 7 very torsionally rigid, so no twisting of the mounting system 5 into the sensitive solar modules 4 can be initiated.

The 4 shows a side plan view of a row 3 of the mounting system 5 the solar energy system 1 to clarify their structure again. It can be seen that the cross struts 9 on a front panel 12 and on a rear panel 13 are attached. Perpendicular to the cross struts 9 is a longitudinal strut 10 shown with their end portions on the cross struts 9 rests and are screwed with these. On the longitudinal struts 10 is the solar module 4 Lines up and over the fasteners 11 fixed.

rear plate 13 , Cross struts 9 , Longitudinal struts 10 and front panel 12 form an arcuate or -like, self-supporting construction, even without the solar module 4 is consistent.

In particular, the solar module 4 just placed on the self-supporting construction and then fastened. rear plate 13 and front panel 12 form the supports for the frame module 7 , To rest on the flat roof 2 are the support rails 6 provided, which are perpendicular to the longitudinal extent of the front panel 12 , Rear panel 13 , Cross struts 9 and / or rectified to the projection of the longitudinal strut 10 on the flat roof 2 extend.

The support rails 6 are designed as Aluminiumkantprofile, with each side beveled wings 14 extend to a design-related rigidity of the support rail 6 to reach. Under the support rails 6 are building protection mats 15 arranged the load on the flat roof 2 spread over a wide area.

The support rails 6 extend below the row 3 and / or the solar modules 4 consistently, allowing the load over the support rails 6 linear on the flat roof 2 and thus spread away. In the circulation area 16 of front plate 12 or the rear plate 13 are the wings 14 recessed so that here the support rail 6 can yield to possibly a troubled surface of the flat roof 2 equalize.

Frontblech 12 and rear plate 13 are aligned parallel or nearly parallel to each other in the illustration shown, at the same time close an angle not equal to 90 ° to the flat roof 2 one, both sheets 12 . 13 in the direction of the front panel 12 are inclined.

The 5 shows in a schematic three-dimensional representation again the substructure 8th , where the front plate 12 , the rear panel 13 as well as the support rails 6 can be clearly seen again. Each of these three components can be realized as an aluminum edge profile. The front plate 12 has a parallel to the footprint aligned foot section 17 on which on a flat area of the support rail 6 rests and to the, angled to the floor space 2 , a stator sheet section 18 connects to the lower crossbar 9 is fastened by means of screws. The rear panel 13 also shows a foot section 19 , which also on the support rail 6 flat and rests on the also a stator sheet section 20 connects, at the upper edge of the other cross strut 9 screwed on. For stiffening have front plate 12 and rear plate 13 further bends on. Between the foot sections 17 and 19 and to a next row 3 shows the support rail 6 the wings already described 14 ,

The 6 finally shows the support rail 6 in a three-dimensional representation obliquely from above, with a right support area 16 to support the foot section 17 of the front panel 12 and a left support area 16 for supporting the foot section 19 the rear plate 13 is trained. At the end regions are each arranged perpendicular to the footprint Verschraungsungsblechabschnitte 21 formed by bending, which with adjacent support rails 6 can be screwed to the reticulated solar energy system 1 to build.

As probably best from the 1 indicates, the mounting system 5 side panels 22 on top of the pages of the rows 3 cover. Together with the front panel 12 and the rear panel 13 form the side panels 22 a surrounding, closed windbreak, so that wind forces can attack hard.

To the aerodynamics of the solar energy system 1 to improve this points in the embodiment of 1 to 6 an upper slot 23 and a lower slot 24 on, which are rectified to the cross struts 9 extend. The slots 23 and 24 allow the penetration of attacking wind, which can pass under the solar module and then escape again. Through this beam is the solar energy system 1 by a slight negative pressure in the space under the solar module 4 opposite the outside of the same solar module 4 sucked, so to speak.

A disadvantage of this embodiment, however, is that at de slots 23 and 24 are open to the top and thus act as a funnel for contamination and the like. In particular, it can not be ruled out that soiling, initially on the outside of the solar module 4 lie over the solar module 4 slip off and into the lower slot 24 enter.

The 7 shows an in a schematic three-dimensional representation with partially suppressed components an improved, second embodiment of the invention. After this is structurally very similar to the first embodiment, will be discussed below only the differences. In this embodiment, the lower slot is on the bottom side and forms a vertically oriented opening surface, which on one side by the support surface - ie the flat roof 2 - and on the other side by the cross strut 9 is formed. In particular, the lower slot 24 spaced from the solar module 4 arranged. This structural design has the advantage that dirt now can not penetrate from above or fall into it.

The internal structure of the solar energy system 1 is as a side view in the 8th shown:
In the area of the upper slot 23 lies the longitudinal strut 10 on the crossbar 9 on and linearly carries the solar module 4 , The fasteners 11 are still in the region of the upper slot in the longitudinal direction of the longitudinal strut 10 movable, so that individual adjustments to the size of the solar module can be made. The upper slot 23 is thus due to the spacing of the solar module 4 from the crossbar 9 through the longitudinal strut 10 reached.

At the lower end, the longitudinal strut pushes 10 T-shaped to the crossbar 9 so that these together create a support surface for the solar module 4 form. The edge of the solar module 4 is gap-free on or at the cross strut 9 on or on. Thus, no contamination from above can occur at this position. The fastener 11 is at the bottom of the solar module 4 also on the crossbar 9 attached. Thus, the area is adjacent to the solar module 4 closed and the lower slot 24 laid in the ground area.

How to get better from the 7 results, is the front panel 12 the previous figures on support sections 25 reduced, which on the support rails 6 are arranged and a similar width as the support rails 6 exhibit. Between the individual support sections 25 are the lower slots 24 arranged. The grid of the support rails 6 and thus the support gates 25 does not necessarily have the dimensions of the solar modules 4 but may also have a different pitch. Another advantage of laying the lower slots 24 adjacent to the floor or flat roof 2 is that interfering contours up to a certain height on the flat roof 2 can be tolerated because the support sections 25 can be grouped according to the Störkonturen.
