Description

The invention relates to an arrangement of two adjacent PV module units held by support elements at a predeterminable height above the ground, each PV module unit having a boundary edge to the adjacent PV module unit and a PV module unit edge facing away from the boundary edge.

In the construction of photovoltaic open space systems usually a support structure is erected for the plurality of photovoltaic modules, which consists of columns of different lengths. On the supports transverse bars are arranged, which extend over the supports of the same length. Again transversely to the transom a plurality of parallel bars is arranged in a grid, which is adapted to the length or width of the photovoltaic modules. On the spars then the actual framed or unframed PV modules are attached by means of brackets. The shorter columns have a length of about 1.2 meters and the longer columns can reach lengths of up to 3 meters or more. Supports of the known lengths require a secure anchoring in the ground, which in turn causes additional costs in the form of pile work or incorporation of foundations. The high supports offer the advantage that the photovoltaic modules are freely accessible to a fitter from below, without having to stoop or distort them. This is especially important for the subsequent care of the terrain on which the photovoltaic system is. For reasons of environmental protection, this is usually a green area, which must be regularly mowed in the summer.

In recent years, a dramatic decline in prices for photovoltaic modules has been observed, which is likely to continue. It follows that in contrast to earlier than the steel and / or wooden construction of the scaffold accounted for about 10 percent of the equipment costs, today a share of the total cost of 20% to 30% for the substructure must be stated. It is therefore important to maintain the competitiveness, lower the cost of the substructure.

At the Intersolar 2012 in Munich Schüco presented an arrangement of the type mentioned above for mounting on a roof. In the arrangement shown, the PV module units are facing each other in the manner of a saddle roof and connected together at the top. In a transfer of the system shown on an open space system problems may be expected to the effect that the intended to rest on a roof construction receptacles are not suitable for use on natural ground. In addition, the natural subsurface of an open space system consists of soil and grassy vegetation, the latter shrouding the PV modules if the known support bearings were used on natural ground, since grass would grow much higher than the level of the PV modules on the open space. Corresponding yield losses would be expected.

From the EP 2 154 729 AB1 An arrangement is known in which starting from a common corner, four each two-axis inclined upwardly extending PV modules are provided. The arrangement of four PV modules is taken in a circumferential supporting frame on the further support is not discussed further. A variant with support elements suggests that the support frame is supported from below via a central support element, run out of the obliquely upwardly extending arms.

The invention is therefore based on the object to provide a structurally simple and inexpensive substructure for a photovoltaic open space generator, which is also suitable for a construction of low height.

This object is achieved in that the support elements are partially introduced into the ground and arranged exclusively on the side of the PV module unit edge, wherein the marginal edges have a greater distance from the ground than the remote PV module unit edges. Thus, an aerodynamic disadvantage is accepted to the extent that in order to avoid the efficiency of the PV generator negatively influencing grass growth above the PV modules, they are set high. The aerodynamic disadvantage arises from the fact that in high-set PV modules, the wind can undercut these at high speed, which may mean the risk of flying away from PV modules or entire areas of the PV generator. This disadvantage is taken into account by the fact that the anchoring in the ground a corresponding counterforce is available, which counteracts wind-induced lifting of PV modules.

It should be noted that a PV module unit can consist of a single PV module of any size or of several PV modules, in particular behind or next to each other. When using the term "direct or indirect" connection, attachment and the like. It is understood that the involved components can be connected directly, so directly or with the help of other unnamed components, such. As screws, rivets, brackets, tabs, etc., which may have no direct contact of the components involved result.

It is particularly advantageous if the boundary edge and the remote PV module unit edge of both PV module units run parallel to the substrate essentially in the north-south direction. By this measure, in conjunction with a continuous placement of the available outdoor area without a required adherence to distances between PV module units to prevent shadows, a particularly effective operation of the photovoltaic generator can be achieved. When framed PV modules are used, the edge or edge of the module unit is the frame and, when using unframed PV modules, in particular, the glass edges thereof and / or PV modules with bottom rails (backrails) their ends.

To achieve a structurally simple substructure, it is advantageous if the support elements have at their head end, in particular centrally to the support element arranged cross member, are provided at both ends fastening points for direct or indirect attachment of the remote module unit edges. One support element then provides two support points for fixing the PV unit. The PV units themselves may be designed as bearing surfaces, which are arranged at the two ends of the cross member, on which a module frame or a rear rail or other connecting means between two support elements are supported. Instead of a plurality of aligned cross beams and a single long cross member, which is also referred to as a transverse loader can be used, which is supported over several support elements away. This offers the advantage that with a more inaccurate mounting of the support elements nevertheless a desired grid spacing for the fastening means can be achieved.

The support elements can on the bottom side means, for. B. in the form of a plate, which is to be understood as a constructive measure that prevents unimpeded penetration of the support element in the ground. It may therefore be anti-Eindringbauteile having wing-like ridges in the manner of a ski pole, or flat sheets or concrete slices, etc. In particular, in addition to the anti-Eindringteil this may be provided below with a rod. Under rod while every elongated component is understood, such. As a solid rod, a square tube, a round tube, etc., which is suitable to rigidly connect the plate with a support plate. The rod can be extended at the bottom of the plate by a piece, so that a spike is formed, which is intended to penetrate into the ground. The mandrel prevents lateral slippage of the ground support and also offers a small contribution to counteract a wind-induced buoyancy. However, the buoyancy force is essentially countered by the dead weight of the assembled PV modules, which prevents the ground support from lifting off the ground.

If an inclined support surface is provided, from which the connecting means between two opposing support elements, so the inclined support surface is in particular designed as a fold, under which any kind of change in direction of the surface of the support plate is understood. A downwardly facing edge has an obliquely downward surface result. The fold itself may be a clear edge, but also a curve or any other suitable shape, which has the desired change in direction of the support surface result. In this case, an additional component such. As an applied sheet metal strips are used.

The measures mentioned offer the particular advantage that the heavy components of the classic substructures such as columns, crossbeams and spars are eliminated and replaced by a variety of light and handy floor supports.

This makes it possible to design the distance between the plate and the support surface between 30 cm and 100 cm, in particular between 40 cm and 80 cm, and particularly preferably between 50 and 60 cm. The supports for the photovoltaic modules are thus relatively short compared to the prior art, which reduces the cost of materials. Due to the low overall height, wind can not undercut the substructure and generate correspondingly high buoyancy forces under the photovoltaic modules, as is the case with higher-placed PV modules. The photovoltaic modules are virtually dipping into the landscape and offer little access to wind.

Further embodiments of the support elements are in the own application DE 10 2011 1169265 described. The content of this application should be integrated with respect to the execution of the support elements, the connection between the support elements, the anchoring possibilities in the ground and the means for fixing PV module units on the connecting means in the disclosure of the present application.

As will be explained in detail later with reference to the figures, the connecting means may have very different designs, which partly manage with and without the involvement of structural elements of the PV modules. The The following non-exhaustive list identifies a snippet of possible design elements that may be involved in the connection means:

• - A V-shaped rail with spaced module edge holders, wherein the grid spacing of the PV module width corresponds to the PV modules used in the PV module units;
• - Two profile rail halves, which are connected together centrally via a connecting element, wherein the connecting element is in particular at the same time a module edge holder;
• When using frameless PV modules, the back side rail (s) called this "backrail";
• - when using framed PV modules, part of their frame;
• - A supported against the support element strut; and
• A three-dimensional support structure.

In order to avoid damage due to friction between the connection means connecting two support elements and the PV module units, it is expedient if at least one spacer is fastened on the connection means or on the PV module unit, which establishes a direct contact between the connection means and the PV module unit prevented. Additional spacers are required to prevent collision of adjacent photovoltaic module units. At least one spacer should be arranged at the vertex of the V-shaped connecting means, be it as a flat band or as a rail.

As mentioned above, this arrangement is intended in particular for low-profile photovoltaic panels. In addition, it can also be used for high-building fields, in particular in the range between 190 cm and 240 cm, when the outside lying on the field edge support elements are braced for fixing obliquely or made of solid components, such. As IPE-carrier, are made. In this way, darkened greenhouses can be created for the growth of shade trees, which also act as energy suppliers.

Further advantages and embodiments of the invention will become apparent from the description of embodiments with reference to FIGS. Show it:

12 a high system with stabilized edge supports.

In the 1 is a perspective view of two support elements 1a . 1b shown, with each support element 1a . 1b at the top of his head 2 a crossbeam 3 having. The crossbeam 3 is preferably centered on the respective support element 1a . 1b attached, leaving an equal load at both ends 5a . 5b symmetrical on the support element 1a . 1b is transmitted. Between the two opposite ends 5a the crossbeam 3 is a first rail 21a arranged and between the two opposite ends 5b in an analogous manner, a second rail 21b , The arrangement shown is the smallest unit that can be used. On the profile rails 21a . 21b are module brackets or module edge brackets 9 mounted, the two photovoltaic module units 11 Fix, briefly called PV module units, with the at the vertex S or the center of the rails 21a . 21b arranged module edge holder with the reference numeral 9a is provided and arranged on the profile rail end module edge holder with the reference numeral 9b , In the present case therefore includes each PV module unit 11 a single PV module. Thus, in this case, the module edge arranged at the higher level is at the same time an edge G to the adjacent PV module unit 11 which also consists of only a single PV module. The edge of the PV module unit facing away from the boundary edge G. 11 , which also corresponds to the lower PV module edge in the present embodiment, is denoted by the reference numeral 12 Mistake.

The 2 shows a cross section along the line II-II from the arrangement of the far involved components, ie support elements 1a . 1b , Cross member 3 , Profile rails 21a . 21b , Module edge holder 9a . 9b and PV module units 11 , is shown from a different point of view. The distance from two adjacent module edge holders 9 . 9a . 9b is referred to as grid spacing R, regardless of the position of the module edge holder 9 . 9a . 9b at the edge of the profile rail 21a . 21b , in the middle or in the course of the rail length. From the 2 It can be seen that the distance A of the vertex S, and the boundary edge G to the ground U is higher than the distance A ₁ between the ground U and the remote module unit edge 12 ,

In the 2 three detail images 2a, 2b and 2c are indicated by circles. The first detailed view 2a shows the centrally arranged module edge holder 9a , a first and a second pocket or groove 13a , respectively. 13b for the edge of the left or right PV module unit 11 , The module edge holder 9a is in particular formed in one piece, wherein at the bottom of a passage 15 is provided by the rail 21a . 21b is guided. In this variant, the complete number of module edge holders must 9 . 9a . 9b for the intended PV module number of a PV module unit 11 is needed, before fixing the rail 21a . 21b to the cross beam ends 5a respectively. 5b on the rail 21a . 21b be threaded. They are also module edge holders 9 . 9a . 9b possible consisting of two or more parts, so that they later, with already fixed rail 21a . 21b can still be mounted on this.

The second detail figure 2 B shows the same thing at one end of the rail 21a . 21b , The module edge holder 9b has only a single insertion groove 13 on and it's a jig 17 provided that it allows him to move safely on the rail 21a . 21b to fix. From the 2c is still a spacer 19 apparent when using large PV modules in the PV module unit 11 supports the back of the PV module.

Another alternative to the connecting means provides a relatively rigid, V-shaped preformed rail 21a . 21b to use. Then there is a one-piece lanyard, which can be fitted prefabricated with all PV modules. The PV module units are then defined so that in each case all PV modules, between one of the support elements 1a or 1b and the vertex S, are to be understood as a PV module unit in the context of this application. The same situation arises in the case of pre-bent arc segments or arch elements, which have a support element support area which is higher than the sink point of the arch element.

The 3 and 4 show a series of three construction units after the 1 , wherein instead of a single PV module, the PV module unit 11 now each have three juxtaposed PV modules. Correspondingly, the boundary edge G is the upper module edge of the uppermost PV module and the remote PV module unit edge 12 the lower module edge of the lowest lying PV module. Another variation of this embodiment is that the PV module units 11 now from the adjacent rails 21a . 21b of different support elements 3 be worn and held. From the sectional view IV-IV of the 4 you can see the three different types of module edge brackets 9 . 9a . 9b , wherein the central module edge holder 9a from the other module edge holders 9 it differs in that it has a v-shaped implementation 15 and not one more just like the rest of the module edge brackets 9 between the PV modules of a PV module unit 11 are arranged. V-shaped means that the part itself has the shape of a V, ie a point or a curve with two adjoining legs and not that the cross-section of the profile itself is designed as V. The cross-section may have any suitable rigid shape, with a simple box profile, possibly provided with reinforcing webs, sufficient. The profile rails 21a . 21b In the simplest case, they can be a flat band or also profile strips with a plurality of bent webs, so that a connecting means which does not bend or only slightly deflects between the support elements 1a . 1b is present.

The 5 and 5a show a variant that can be used when on PV module units 11 each one or more frameless PV modules with back rails 23 have. As a rule, each of the frameless PV modules has two of these back rails, which are inherently strong enough to perform a supporting function for the frameless PV module. The connecting means between the support elements 1a and 1b then cover the back rails 23 in combination with a set of rigid shoes 25 with two recesses in the case of two too connecting rear rails 23 as in the case of 5 shown, or only one recess, if only one at the outer edge of the PV module unit 11 lying back rail 23 with the end 5a . 5b of the crossbeam 3 to connect.

In the 6 with detail figure 6a an arrangement according to the invention is shown in which the connecting means between the support elements 1a . 1b two profile rail halves 27a . 27b includes, each of a support element 1a . 1b proceeding in a V-shaped upward and at the apex S in a ridge 29 open where their two ends by a rigid connecting element 31 are fixed to each other. The profile rail halves 27a . 27b may possibly be asymmetrical.

The 7 shows an embodiment for framed PV modules. These have a surrounding frame 37 whose sections along the module width B at the same time a part of the connecting means between the support elements 1a . 1b form the distance between the two support elements 1a . 1b bridged. The sections along the longitudinal side of the PV modules are also to be regarded as part of the connection means, by adjacent PV modules there via a rigid module edge holder 9 . 9a . 9b be connected to each other.

The 8th shows the perspective view of a field 41 with several arrangements according to the 3 and the 9 a supervision and 10 a cross section to the field 41 , In particular from the 10 It becomes clear that at the top and bottom vertex, corresponding to the ridges and throats of the roof-like construction, special forms of module edge holders 9 useful for their design, such as the intended slope of the PV module units 11 to each other, the PV module type, if necessary, the attachment to the cross member 3 etc. are used.

In the 11 is shown as the PV modules of the PV module units 11 not at its module edge with the connecting means, for. B. the V-rail 21 , but by means of several adhesive pads 45 or more snap-in or clamped connections, etc., which are attached to the back of the PV modules. A suitable position of the adhesive pads 45 is z. B. approximately one quarter of the module length and module width of the longitudinal or transverse edge of the PV module indented. The adaptation to the width of the PV modules then looks like that there is a grid dimension R 'that makes up about half of the module width. In general, therefore, the dimension R, R 'is to be understood as the dimension with which the elements supporting the PV modules, irrespective of their type, are connected to the connection means.

In the 12 a high-level arrangement according to the invention is shown. As mentioned above, this construction serves as a greenhouse for shade plants, whereby also its side surfaces can be equipped depending on the sky direction with PV modules or glass panes. The PV module units 11 or the PV modules forming them can be purposefully separated from one another by joints, in order to achieve a defined incidence of light and an outflow of rainwater to defined locations.

The outer support elements 1a . 1b are for fixing by means of a steel cable 47 obliquely braced or consist of solid components, such. B. IPE carriers ( 43 ), which are anchored in the subsurface U. This protective measure against damage due to the influence of shear forces on the field 41 occur, in particular, in the low-building fields considered here 41 with a small height of 40 cm to 100 cm makes sense.

In particular, when using a rigid connecting means and more complex components than rails can 21a . 21b come into question, so that at the same time a clear contribution to stability is made. So z. B. the connecting means to the outer support elements 1a . 1b of the field 41 be designed as a three-dimensional support structure, which includes components such as a truss frame, a honeycomb structure, a node structure, a wave structure and the like.
