Abstract

The present invention describes a device (10) for the open-air installation of individual solar modules (46) and solar modules (14) on a substrate (12) and a method for this. The substructure (10) according to the invention for the open-air installation of individual solar modules (46) and solar modules (14) on a substrate (12) also allows the processing or cultivation, especially the agricultural cultivation of the substrate (12), especially when this is done with agricultural machines and soil cultivation equipment. In addition, the substructure (10) allows the arrangement of the individual solar modules (46) or solar modules (14) in such a way that no hard, purely geometric and restless optical image is created in a rather soft and round landscape topography, but rather a soft and round landscape character can be reproduced. The substructure (10) also avoids the optical leveling of an otherwise topographically varied landscape. Another advantage is that the substructure (10) can be expanded in any modular way, i.e. it can be designed with any number of truss areas and supports (16).

Description

The present invention relates to a device for the open-air installation of individual solar modules and solar modules on a substrate according to the preamble of claim 1 and to a method for the open-air installation of individual solar modules and solar modules according to the preamble of claim 10.

An open-air installation of solar modules on a subsurface is usually carried out with a framework on which longitudinal beams rest. In order to protect such a substructure against wind and weather, cross braces and bracing are usually used between the posts and longitudinal beams, which form a vertical wind bracing. Such a design is used, for example, in the EN 10 2011 007 521 A1 from which the present invention is based.

Such substructures have numerous disadvantages, especially when built over agricultural areas.

On the one hand, the vertical wind forces make it more difficult to cultivate or manage agricultural land, especially when this is done with agricultural machinery and soil cultivation equipment.

On the other hand, the one or more solar modules are arranged on the substructure in the form of a shed roof (sawtooth roof) or gable roof. This allows the solar modules to create a hard, purely geometric and restless optical image in a rather soft and round landscape topography.

Finally, these substructures, which are always aligned and leveled in relation to a highest elevation, result in an optical leveling of an otherwise topographically varied landscape.

It is therefore an object of the present invention to propose an open-air installation of solar cells and solar modules on a substrate, with which at least one of the disadvantages described above is overcome.

This object is achieved with the device according to the invention for the open-air installation of individual solar modules and solar modules according to claim 1 and the method according to the invention for the open-air installation of individual solar modules and solar modules according to claim 10. Advantageous further developments are specified in the dependent claims and in the following description together with the figures.

The inventors realized that this problem can be solved in a surprising and particularly simple way by using a framework supported by the posts instead of a vertical wind bracing. This framework forms a non-vertical, preferably horizontal or parallel to the subsoil wind bracing, which, in conjunction with the posts and the subsoil, enables sufficient load transfer even when high loads are applied due to wind and weather.

The device according to the invention for the open-air installation of individual solar modules and solar modules on a substrate, wherein the device has at least three stands for arranging the device on the substrate and at least two longitudinal beams which are supported by the stands, is characterized in that the stands support a framework, wherein the longitudinal beams are part of the framework.

In the context of the present invention, a distinction is made between “individual solar modules” and “solar modules”. “Individual solar modules” are individual solar modules and “solar modules” are several combined “individual solar modules”.

In an advantageous further development, there are no tensioning devices, in particular no tension cables, which are arranged directly between the posts and the framework. This means that the subsoil can be worked and cultivated particularly well even after the device has been set up.

In an advantageous further development, there are no tensioning devices, in particular no tension cables, which are arranged directly between two stands. This means that the subsoil can be worked and cultivated particularly well even after the device has been set up.

In an advantageous further development, there is no vertical wind bracing. This means that the subsoil can be worked and cultivated particularly well even after the device has been set up.

In an advantageous further development, the framework forms a non-vertical, preferably horizontal or parallel wind bracing to the substructure. This makes the substructure particularly stable and durable.

In an advantageous further development, it is provided that there are first longitudinal beams and second longitudinal beams running at an angle thereto, wherein the first longitudinal beams and the second longitudinal beams are preferably arranged at a right angle to one another. This makes it particularly easy to form the substructure with the framework.

In an advantageous further development, at least one upright, preferably all uprights, are arranged at nodes between first longitudinal beams and second longitudinal beams on the framework. This makes the substructure particularly stable and durable.

In an advantageous further development, there are tensionings within the framework, particularly in the form of tension cables. This makes the substructure particularly stable and durable. By providing a certain number of tensionings, the stability can be adapted to local conditions and requirements.

In an advantageous further development, it is provided that within the framework there is at least one bracing between longitudinal beams, with the bracing preferably being between the second longitudinal beams. This makes the substructure particularly stable and durable. By providing a certain number of bracings, the stability can be adapted to local conditions and requirements.

In an advantageous further development, it is provided that the framework is aligned differently in adjacent areas, wherein the areas preferably have a maximum of 16 posts, preferably a maximum of 8 posts, in particular a maximum of 4 posts.

This allows a landscape topography to be optically reproduced particularly well, so that the landscape image is not leveled.

In an advantageous further development, the framework is at least partially aligned, preferably in the area of at least 8 posts, preferably in the area of at least 16 posts, in particular completely parallel to the ground and/or horizontally. This allows the landscape topography to be optically reproduced so that the landscape is not leveled. This can of course also be achieved with more than 16 posts, but with any number of posts.

In an advantageous further development, the posts extend downwards from the framework, preferably normally downwards. This means that the subsoil can be worked and cultivated particularly well even after the device has been set up. This is all the more true if there are no bracing or struts in the area between the subsoil and the framework, and in particular no other elements apart from the posts.

In an advantageous further development, the stands have at least two parts that can be moved relative to one another, preferably telescopically. This means that by moving the two components longitudinally relative to one another, additional fine leveling/terrain adjustment to the ground can be achieved.

In an advantageous further development, the substructure is not static but elastically deformable. This makes the substructure particularly stable and durable because the substructure acts as an additional damper and the posts and uprights are elastically clamped.

In an advantageous further development, the posts are inserted into the subsurface to a certain depth. This makes the substructure particularly stable and durable. By setting a certain insertion depth of the posts into the subsurface, the stability can be adapted to local conditions and requirements.

In an advantageous further development, it is provided that there are mounting elements that serve to attach the individual solar modules or solar modules to the framework, whereby the mounting elements are preferably designed for an arrangement of the individual solar modules or solar modules that runs parallel to the framework. This makes it very easy to attach the individual solar modules or solar modules to the substructure. In addition, the landscape topography can be remodeled not only with the substructure, but also with the individual solar modules and solar modules, so that leveling of the landscape is avoided.

In an advantageous further development, the first longitudinal beams and the second longitudinal beams are firmly connected to one another. This makes the substructure particularly stable and durable.

In an advantageous further development, it is provided that the bracing with the longitudinal beams is firmly connected. This makes the substructure particularly stable and durable.

In an advantageous further development, the posts are firmly connected to the framework. This makes the substructure particularly stable and durable.

In an advantageous further development, there is at least one joint between two truss areas. This allows topographical terrain adjustments to be made in that the first longitudinal beams and/or the second longitudinal beams are not connected in alignment with one another.

In such a joint between two first longitudinal members, a second longitudinal member arranged on a first longitudinal member could rest on the other first longitudinal member, in particular before a screw connection is made.

On the other hand, a second longitudinal member could also rest on a first longitudinal member to which another second longitudinal member is attached, in particular before any screwing is carried out.

If at least one of the fixed connections is a screw, rivet or welded connection, then the corresponding connection is particularly easy and cost-effective to produce and at the same time very safe and durable.

In an advantageous further development, the framework is provided with infills. This makes the substructure particularly stable and durable. In addition, the subsurface can be sufficiently exposed to wind and weather.

In an advantageous further development, it is provided that adjacent infills are arranged offset from one another in at least one direction, with the offset preferably being 50% of the longitudinal extent of the infill in that direction. This makes the substructure particularly stable and durable.

In an advantageous further development, it is provided that there are at least two infills of different sizes, whereby the size ratio of the infills of different sizes is 1/1 to 1/2 or 1/3 to 2/3 or 1/4 to 3/4 or 1/5 to 4/5 or 2/5 to 3/5 or 1/6 to 5/6. This makes the substructure particularly stable and durable.

Independent protection is claimed for the method according to the invention for the open-air installation of solar modules on a substrate, wherein at least three stands are used for arrangement on the substrate and at least two longitudinal beams which are supported by the stands, which is characterized in that a framework is created which is supported by the stands, wherein the longitudinal beams are arranged such that they are part of the framework.

In an advantageous development, it is provided that the device according to the invention is used.

The features and further advantages of the present invention will become clear below from the description of a preferred embodiment in conjunction with the figures. These show purely schematically:

• 2 a first detailed view of the device according to 1 ,

In the 1 to 11 the device 10 according to the invention is shown in interaction with a substrate 12 and solar modules 14.

It can be seen that the device 10 has vertically V-shaped stands 16 which are posts 18 driven into the ground and supports 20 attached thereto.

A framework 22 is arranged horizontally H on the uprights 16, which has first longitudinal beams 24 and second longitudinal beams 26, which run perpendicular to one another. The first longitudinal beams 24 are each attached to the uprights 16 in rows and the second longitudinal beams 26 are arranged perpendicular to them to form columns 28. More precisely, between two second longitudinal beams 26a, which in turn are also attached to the uprights 16 and form node points 30 there with the first longitudinal beams 24, further second longitudinal beams 26b are arranged on the first longitudinal beams 24 at equal intervals.

Between the second longitudinal beams 26, struts 32 are arranged which run perpendicular to the second longitudinal beams 26 and parallel to the first longitudinal beams 24.

The struts 32 are arranged in such a way that two infills 34, 36 of different sizes result in the framework 22, namely first infills 34 and second infills 36. The first infills have a size ratio of e.g. 1/3 to 2/3 in relation to the second infills. The infills 34, 36 are each limited by the second longitudinal beams 26 in their length l and by the first longitudinal beams 24 and the struts 32 in their respective widths ba, bb. Due to the uniform spacing of all second longitudinal beams 26, all infills 34, 36 each have the same length l, but have different widths ba, bb according to their size ratio.

The infills 34, 36 of a column 28a are arranged offset with respect to the infills 34, 36 of an adjacent column 28b in order to achieve further stiffening. More precisely, the struts 32a, 32b of adjacent columns 28a, 28b are arranged offset by the width bb of an infill 34.

In the embodiment of the device 10 according to the invention shown, diagonally running bracings 38 are inserted into the second infills 36 in order to further stiffen the framework 22. The bracings act over 2/3 here. The tensioning force of these bracings 38 is adjustable 40 (turnbuckles) (cf. 4 ).

Depending on the stability requirements and local conditions, only the first infills 34 could be provided with such bracing 38 (bracing over 1/3). On the other hand, all infills 34, 36 could be braced individually or only some of the infills 34, 36 could be provided with bracing 38. In addition, the bracing 38 can also extend over several infills 34, 36, for example acting on a first infill 34 on the one hand and on an adjacent infill 36 in a column 28 on the other hand, i.e. acting over 3/3.

The solar modules 14 are packages consisting of a plurality of individual solar modules 46 arranged parallel to one another in lateral holders 44. These solar modules 14 are attached to mounting elements 48, which in turn are attached to the second longitudinal supports 26.

The solar modules are, for example, solar modules according to the teaching of EP 3 231 016 A1 This means that the subsoil 12 can continue to be particularly well cultivated for agricultural purposes.

The first longitudinal members 24 are connected to the second longitudinal members 26 via connectors 50.

All elements of the substructure can be made of galvanized steel or galvanized steel sheets to increase durability for a period of approx. 25 years.

In addition, expansion joints (not shown) can also be provided to compensate for temperature-related length fluctuations. These expansion joints could be implemented, for example, by telescopically designed first longitudinal beams 24 or telescopically designed second longitudinal beams 26.

• Zuerst werden die Pfosten 18 in den Untergrund 12 getrieben, wobei eine vorher festgelegte Eindringtiefe an der Einspannstelle 52 im Untergrund 12 eingehalten wird, um eine optimale Dämpfung und damit Stabilität der Unterkonstruktion 10 im Betrieb zu erzielen. Diese gewünschte Eindringtiefe kann über die Bodenbeschaffenheit bzw. Bodengutachten ermittelt werden, wobei sie bei einem typischen Lehmboden beispielsweise 1,5 m beträgt.

The construction of the substructure 10 according to the invention is now carried out as follows:

• First, the posts 18 are driven into the subsoil 12, whereby a predetermined penetration depth is maintained at the clamping point 52 in the subsoil 12 in order to achieve optimal damping and thus stability of the substructure 10 during operation. This desired penetration depth can be determined from the soil condition or soil report, whereby for a typical clay soil it is, for example, 1.5 m.

The supports 20 are then screwed to the posts to form the uprights 16. The first longitudinal beams 24, which are designed, for example, as Z-300 profiles for a span of 6 m, are screwed to the supports 20 as base beams.

The second longitudinal beams 26, which are designed as Z-180 profiles for a span of 6.48 m, the mounting elements 48 are screwed. The second longitudinal members 26 are then screwed to the first longitudinal members 24 using the connectors 50, which are designed as Z-connectors.

The struts 32 are inserted and screwed between the second longitudinal beams 26. The struts 32 are designed as an L-profile. These struts 32 are inserted alternately 1/3 and 2/3, so that the differently sized infills 34, 36 are created.

Bracings 38 in the form of steel cables are then inserted into individual infills 34, 36, as required by the stability requirements, whereby the bracings 38 can act, for example, over 1/3, over 2/3 and/or over 3/3 or other sizes. The rectangular shape of the infills 34, 36 is adjusted using the turnbuckles 40.

The solar modules 14 are now placed on the mounting elements 48, with mounting tabs 54 of the solar modules 14 engaging through corresponding mounting slots 56 of the mounting elements 48. The mounting tabs 54 are then fixed and secured in their position by securing means in the form of locking pins 58, for which purpose the mounting tabs 54 have corresponding openings through which the securing means 58 are inserted.

Even if it was assumed in the above description that the framework 22 and thus the infills 34, 36 are rectangular, it is in principle also possible to provide a different geometric design, in particular a polygonal, parallelogram-like, round, oval or curved shape.

Although the above description assumes that the framework 22 is aligned horizontally, it could also be aligned differently, in particular to run parallel to the base 12. The uprights 16 therefore do not have to be attached to the framework 22 in a normal manner, but can be arranged in an orientation other than vertical to the framework 22.

For example, if the base 12 is inclined to the horizontal H, the posts 16 would be aligned vertically V, but the truss 22 would be aligned parallel to the base 12.

If there are local changes in alignment in the subsurface 12, for example if the subsurface 12 is wavy, then the infills of the framework 22 could be locally aligned parallel to the subsurface, so that overall a wavy framework 22 is also produced.

This is in connection with the 7 to 11 described in more detail.

It can be seen that the subsoil 12 is undulating, in this specific case with a height difference (cf. 8 ).

This is compensated by appropriately provided joints 60, 62, 64, 66, which are each provided between two truss areas 22a, 22b, 22c at the locations of individual uprights 16.

More precisely, there are joints 60, 62 for a bend in the course of the first longitudinal beam 24 (see the 9 , 10a and 10b) and articulation points 64, 66 for a bend in the course of the second longitudinal members 26 (cf. 11 ).

The articulation points 60, 66 are each concave articulation points where the angle between the two truss sections is less than 180°, and the articulation points 62, 64 are each convex articulation points where the angle between the two truss sections is greater than 180°.

In contrast to the nodes 30 in a linear transition of the first longitudinal members 24, two second longitudinal members 26aa, 26bb are provided next to each other at the articulation points 60, 62.

The left first longitudinal member 24aa is firmly connected to the left second longitudinal member 26aa via a left connector 50a and the right first longitudinal member 24bb is firmly connected to the right second longitudinal member 26bb and the left first longitudinal member 24aa via a right connector 50b.

The left first longitudinal member 24aa has a cutout 68 in the upper Z-profile area in its right section, which extends beyond the support 20, and the right first longitudinal member 24bb has a cutout 70 in the lower Z-profile area parallel thereto. As a result, the right first longitudinal member 24bb, which is arranged behind the left first longitudinal member 24aa, can be firmly connected to the left first longitudinal member 24aa via the connector 50b.

The right second longitudinal beam 26bb rests on the right first longitudinal beam 24bb, which results in a pivot joint for the truss area 22b around the truss area 22a. This pivot joint is formed by the right second longitudinal beam 26bb. The elongated holes 71 in the individual elements (both vertical and horizontal elongated holes) allow a certain amount of pre-fastening (by means of screw connections not shown) of the individual elements to one another and a subsequent adjustment of up to 10°, after which the final fixing can be carried out by screwing. In order to achieve this adjustment range, the elongated holes of individual elements are preferably arranged rotated by 90° to one another, ie if an element has a horizontal elongated hole 71, it should coincide with the elongated hole 71 of another element that is aligned vertically.

When, after pre-fastening, the truss area 22b is aligned so that it runs parallel to the substrate 12, the right connectors 50b are firmly screwed to the left first longitudinal beams 24aa and the right first longitudinal beam 24bb.

In the case of the convex articulation point 62, the left first longitudinal member 24aa' is firmly connected to the left second longitudinal member 26aa' via a left connector 50a' and the right first longitudinal member 24bb' is firmly connected to the right second longitudinal member 26bb' via a right connector 50b' and is also screwed to the left first longitudinal member 24aa'.

The left first longitudinal member 24aa' has a cutout 72 in the lower Z-profile area in its right section, which extends beyond the support 20, and the right first longitudinal member 24bb' has a cutout 74 in the upper Z-profile area parallel thereto. As a result, the right first longitudinal member 24bb' can be arranged in front of the left first longitudinal member 24aa'.

The right second longitudinal beam 26bb' in turn rests on the left first longitudinal beam 24aa', resulting in a pivot joint for the truss area 22c around the truss area 22b.

Once again, after pre-fixing, when the truss region 22c is aligned so that it runs parallel to the substrate 12, the right connectors 50b' are firmly screwed to the left first longitudinal beams 24aa' and the right first longitudinal beam 24bb'.

If there is a waviness in the subsurface 12 not only along the first longitudinal beams 24 (cf. 8 ), but also along the second longitudinal beams 26 there is a waviness in the substrate 12 (not shown), then joints 64, 66 are to be provided for the second longitudinal beams 26, as shown in 11 is shown in more detail.

In detail, in the case of a convex joint point 64, the left second longitudinal beam 26cc is firmly connected to the first longitudinal beam 24 and thus to the support 20 via the connector 50. The right second longitudinal beam 26dd rests on the first longitudinal beam 24 and forms a swivel joint for aligning a right truss region 22e with respect to the left truss region 22d.

When the truss portion 22e is aligned to be parallel to the substrate 12, the connector 50 is firmly bolted to the right second longitudinal beam 26dd and the left second longitudinal beam 26cc.

In the case of a concave joint point 66, the right second longitudinal beam 26dd' is firmly connected to the first longitudinal beam 24 and thus to the support 20 via the connector 50. The left second longitudinal beam 26cc' rests on the first longitudinal beam 24 and forms a swivel joint thereon for aligning the left truss region 22e with respect to a right truss region 22f.

When the truss section 22e is aligned so that it runs parallel to the substrate 12, the left second longitudinal beam 26cc' is firmly bolted to the right second longitudinal beam 26dd'.

For local height adjustment, the uprights 16 can also be shortened or lengthened by telescoping the posts 18 relative to the supports 20.

From the above illustration it has become clear that the present invention provides a substructure 10 for the open-air installation of individual solar modules 46 and solar modules 14 on a substrate 12, which also allows the processing or cultivation, especially the agricultural cultivation of the substrate 12, especially when this is done with agricultural machines and soil cultivation equipment. In addition, the substructure 10 allows the arrangement of the individual solar modules 46 or solar modules 14 in such a way that no hard, purely geometric and restless optical image is created in a rather soft and round landscape topography, but rather a soft and round landscape character can be reproduced. The substructure 10 also avoids the optical leveling of an otherwise topographically varied landscape. Another advantage is that the substructure 10 can be expanded in any modular way, i.e. it can be designed with any number of truss areas 22a, 22b, 22c, 22d, 22e, 22f and supports 16.

The claims filed now with the application and also those filed later are without prejudice to the obtaining of further protection.

If, upon closer examination, particularly of the relevant prior art, it emerges that one or other feature is beneficial to the aim of the invention but not crucially important, then a formulation is of course already being sought that no longer contains such a feature, particularly in the main claim. Such a sub-combination is therefore also covered by the disclosure of this application.

The references cited in the dependent claims indicate the further development of the subject matter of the main claim through the features of the respective subclaim. However, these are not to be understood as a waiver of the achievement of independent, objective protection for the features of the referenced subclaims.

It should also be noted that the embodiments and variants of the invention described in the various embodiments and shown in the figures can be combined with one another as desired. Individual or multiple features can be exchanged for one another as desired. These combinations of features are also disclosed.

Features that were only disclosed in the description or individual features from claims that comprise a plurality of features can at any time be adopted into the independent claim(s) as being of essential importance to the invention in order to distinguish it from the prior art, even if such features were mentioned in connection with other features or achieve particularly favorable results in connection with other features.

Thus, all features shown in the general description of the invention, the description of the embodiments, the following claims and in the figures can be essential to the invention both individually and in any combination with one another. These features or combinations of features can each form the basis of an independent invention, the use of which is expressly reserved. Individual features from the description of an embodiment do not necessarily have to be combined with one or more or all of the other features given in the description of this embodiment; in this respect, each sub-combination is expressly disclosed. In addition, physical features of a device can be reformulated and used as process features and process features can be reformulated and used as physical features of a device. Such a reformulation is therefore automatically disclosed.
