Description

[0001] The present invention relates to a solar table for a photovoltaic system with support units, main support units and module support units and to a photovoltaic system with such a solar table and photovoltaic modules.

[0002] Solar tables provide a substructure on surfaces such as open areas, like meadows or fields, or other surfaces such as parking lots, for the installation of photovoltaic modules.

[0003] Solar tables for photovoltaic systems have become established technology. Conventional solar tables have supports for anchoring in the ground. These supports are driven vertically into the earth. Beams are then placed onto the supports using a crane. Mounting brackets are attached to these brackets, onto which photovoltaic modules are mounted. The photovoltaic modules are screwed in place using module clamps. The connecting cables must then be laid and attached to the solar table. C-profiles made of zinc-coated steel are used for the supports, beams, and mounting brackets. A disadvantage is that these profiles are not suitable for large spans. The considerable weight makes installation particularly difficult. Furthermore, the supports must be spaced close together. This often results in the usable area underneath being very limited, if usable at all.Scaling the profiles results in disproportionately large wall thicknesses. This increases the overall manufacturing and assembly costs of the solar tables to such an extent that the gain in usable area beneath the table only pays for itself, if at all, after several years. Large spans are therefore not economically feasible with open profiles.

[0004] The object of the present invention is therefore to provide a solar table for a photovoltaic system and a photovoltaic system which enables a more advantageous use of the underlying area and is at the same time more economical to manufacture and assemble.

[0005] The problem is solved by a solar table with the features of claim 1 and a photovoltaic system with the features of claim 25. Preferred embodiments are the subject of the dependent claims. Further features and properties will become apparent from the general description and the description of the exemplary embodiment.

[0006] The solar table system according to the invention for a photovoltaic system, in particular an agri-photovoltaic system, comprises: - a plurality of support units for transferring the static load into a ground; and - a plurality of main beam units, wherein one main beam can be accommodated on two support units; and - a plurality of module carrier units for receiving photovoltaic modules, wherein a module carrier unit can be received on two main carrier units and a photovoltaic module can be received on two module carrier units.

[0007] The main support unit has a main support with a main support profile which is asymmetrically designed; and / or the support unit comprises at least one support with an open support profile with two legs and six bends; and / or the module support unit comprises a slide-in receptacle for photovoltaic modules.

[0008] The invention has many advantages. A significant advantage is that the design of the support unit, the main support unit, and the module support unit allows for higher stiffness of the individual units. Consequently, greater spans can be achieved. At the same time, thinner walls are required. This makes the system lighter than conventional solar tables, thus requiring fewer supports. As a result, the solar table according to the invention is more economical to manufacture and assemble, while simultaneously enabling improved use of the available space underneath.

[0009] The main girder profile is not symmetrical. This advantageously allows the asymmetrical load acting on the main girder profile to be absorbed and transferred more effectively. This specific profile shape is able to optimally counteract the effects of asymmetrical loads. In particular, the main girder profile includes at least one C-section.

[0010] The insertion recess is advantageously designed so that the photovoltaic module is encompassed on three sides and / or at least partially enclosed. Advantageously, the insertion recesses allow for easy insertion of the modules between two mounted module carriers. Therefore, the photovoltaic module does not need to be additionally screwed to the module carrier unit. A positive-locking connection is advantageously established between the profile of the module carrier unit and the photovoltaic module. The compressive forces acting on the photovoltaic module are transferred via the enclosed end section to the module carrier unit and dissipated over a large area. No screws or other fasteners are required. Due to the cross-section of the insertion recess, particularly in combination with the material quality, mass, and / or thickness, the component exhibits exceptionally high stiffness and stability.

[0011] Preferably, the main support profile of the main support has two legs and a base, wherein the angle between the two legs of the main support profile and the base is, in particular, not 90 degrees. Preferably, a base is located opposite an opening of the profile. In particular, the legs extend away from the base. In an advantageous embodiment, one and, in particular, both legs have a total angle of 180 degrees.

[0012] Preferably, the base has a slope, at least in sections, which determines the inclination of the photovoltaic modules. Advantageously, the module support units can then be mounted directly on the section with the slope. This advantageously eliminates the need for a separate part or similar device to adjust the inclination of the photovoltaic modules, particularly relative to at least part of the solar panel.

[0013] Preferably, the main beam of the main beam unit has a length of more than 8 meters, more preferably more than 9 meters, and particularly preferably more than 10 meters. A length of approximately 10 meters (+ / - 20%) is particularly advantageous. The one-piece main beam is advantageous because it is particularly stiff and lightweight, and therefore particularly economical to manufacture and assemble. The one-piece main beam is also particularly robust.

[0014] Advantageously, the profile of the main beam of the main beam unit has a thickness of less than 5 mm, 3 mm, or 2.5 mm. In a particularly advantageous embodiment, the profile of the main beam has a thickness of 2 mm. Preferably, a profile thickness of 2 mm is sufficient to guarantee the static strength permanently. Advantageously, the profile is made of a metal, and in particular of sheet metal, especially by bending or edging. Advantageously, the main beam is therefore particularly lightweight, and the manufacturing costs are low because the material costs are especially low, particularly for large spans.

[0015] Advantageously, the main support profile of the main beam of the main support unit has at least one lateral bend at the end of one leg. In particular, the main support profile has lateral bends, especially on both legs, which project outwards from the leg. Specifically, the bends point outwards, i.e., away from the opening of the main support profile. Preferably, the bends lie outside the projection surface of the base and are bent outwards, particularly in a V-shape. This advantageously results in even greater stiffness of the main support profile. During assembly, the lateral bends at the lower end of the vertical legs serve as guide rails for mobile work platforms. Furthermore, the bends can advantageously be used to accommodate and guide the cable routing.The same bends can be used as cable trays for the module string cables after the modules have been installed. The main support profile with the bends can also be advantageously viewed as a hat profile.

[0016] Preferably, the main beam of the main support unit, in its intended use, particularly in the assembled state, encompasses and / or at least partially encloses a distal end of the support unit. Advantageously, the main beam is fitted over the distal end of the support. In particular, the main beam encompasses the distal end of the support in its intended use and / or in the assembled state. Specifically, the distal end of the support is received in an opening in the profile of the main beam. This advantageously increases the rigidity of the structure. Furthermore, during assembly, the main beam can initially be securely placed on the distal ends of two supports. This ensures a predefined vertical end position. A horizontal end position can be set and achieved by simply sliding it on the distal ends. The main beam can also be raised by the supports.This rigid design also allows for even better force dissipation in the transverse direction. Furthermore, the overlay and bolting to the main beam closes the profile contour of the support at the top. This makes the system even more resistant to torsional forces around the longitudinal axis, thus increasing the overall system stability.

[0017] Advantageously, at least one connecting unit is included for creating a fixed, and in particular detachable, connection between the main beam of the main beam unit and the support of the support unit. In particular, the connecting unit includes at least one connecting element, which is preferably designed as a connecting bolt and / or screw. Advantageously, the support unit and the main beam unit can thereby be directly connected to each other.

[0018] In particular, the connecting unit has at least one compensating element, and in particular two compensating elements, which compensate for positional tolerances during assembly. Advantageously, the compensating elements include elongated holes. In particular, the elongated holes are formed in the main beam and / or the support, and extend transversely to each other. Advantageously, the elements can also be moved, positioned, and aligned relative to each other even when connected. Advantageously, the main beam unit can be connected to the support unit with only three bolts and nuts, for example, of size M12x25 mm, thus enabling particularly simple assembly.

[0019] The presence of elongated holes on the support of the column unit and the main beam of the main beam unit is advantageous. The connecting unit is advantageously designed to compensate for positional deviations of up to 10° between different main beams and the horizontal slope of the terrain. This allows for particularly good adaptability of the solar table to the specific conditions. As a result, all normal horizontal tolerances occurring during the construction process can be compensated for by the main beam.

[0020] Preferably, at least the column profile of the column of the column unit has at least one symmetry. Preferably, at least the column profile of the column of the column unit has a profile thickness of 2 millimeters, 3.5 millimeters, 4.5 millimeters, or even more. In a particularly advantageous embodiment, the profile has a profile thickness of 3 millimeters. Advantageously, a profile thickness of 3 millimeters is already sufficient to permanently withstand the static load. Advantageously, this achieves a column unit length of more than 4.5 meters, which meets all static requirements. In particular, at least the column profile of the column of the column unit includes inwardly directed chamfers. Advantageously, each of these measures achieves a particularly high resistance to buckling of the column unit.Furthermore, the profile shape with inward-facing edges prevents injuries to people and animals.

[0021] In particular, the support unit comprises at least one ground support, wherein the ground support can be driven into the ground, such as the soil of a field or the like. Specifically, the support of the support unit is receptacleable on the ground support, particularly by being inserted. Preferably, the insertion support reduces the required individual length of the supports, for example, in one embodiment from 5.3 meters to a maximum of 4.3 meters. Furthermore, the weight of the supports is reduced, which facilitates handling during assembly.

[0022] Preferably, the support unit includes an adjustment unit for height compensation and tilt adjustment. Advantageously, a height adjustment of up to 30 centimeters or more between the main support and the table surface can be made at the lower end of the support. This advantageously allows for the compensation of very high tolerances, particularly on uneven terrain. Advantageously, the insertion length of the support can be adjusted via the insertion unit. Advantageously, the adjustment unit includes at least several adjustment holes, which are formed, for example, on the ground support, so that the insertion length of the support can be adjusted in various positions, particularly by means of a screw or other fastening element.

[0023] The module carrier unit preferably includes securing units for fixing and securing the position of the photovoltaic modules, especially within the insertion recess.

[0024] In particular, the securing unit comprises at least one bending tab, which is formed on a module support profile of the module carrier of the module support unit at the insertion point. Specifically, the bending tab can be incorporated after or during the manufacturing of the module support profile. To secure the inserted photovoltaic modules, the bending tab can then simply be bent over, preventing the modules from sliding downwards. The upper bend prevents the modules from being lifted off, thus securing the photovoltaic module in the insertion point. Advantageously, this also eliminates the need for other securing elements, such as module clamps, thereby reducing material costs by €2 / kWp compared to the state of the art. Furthermore, significantly faster module installation is possible. For example, a cost reduction of at least €6 / kWp in installation costs can be expected.The bending tabs can be inserted directly into the module support profile as cutouts.

[0025] In particular, the module carrier profile of the module carrier unit, as well as the cutouts within the module carrier profile, are symmetrically designed. Advantageously, a module carrier of a module carrier unit thus has insertion recesses on opposite sides of the module carrier profile. Furthermore, the symmetry of the elongated holes and cutouts along the longitudinal axis advantageously ensures that the ends of the module carrier can be positioned at either the lower or upper end of the table without requiring a specific installation orientation.

[0026] Preferably, at least one fastening unit is included for attaching the module carrier unit to the main support unit. In particular, the fastening unit includes at least one fastening element, preferably designed as an elongated hole, for aligning and positioning the module carrier unit during assembly. Preferably, the fastening unit includes several elongated holes arranged in the module carriers of the module carrier unit and a further fastening hole in the main support of the main support unit. The fastening can then be achieved by a fastener, such as a screw with a nut. Advantageously, this simplifies handling for the installers and requires no special concentration or precautions for the correct positioning of the module carrier. Advantageously, the fastening of the module carrier units is therefore very simple and quick.

[0027] In particular, the solar table system has a minimum overall height of 2.10 m at the lowest point of the main support unit when assembled. Advantageously, this minimum height of 2.10 m at the lowest point meets the requirements of DIN SPEC 91434, thus ensuring that agricultural machinery can operate beneath the solar table system. This also makes the solar table system suitable for use with photovoltaic systems. Furthermore, it allows for cultivation work to take place beneath the solar table system.

[0028] A span, particularly between the supports, of more than 3.5, 4, or 5 meters is advantageous. This allows for particularly good preparation of the underlying soil. Simultaneously, the solar table system ensures the overall system's structural suitability, taking into account the static load-bearing capacity of the modules, for Germany up to snow load zone 2 and wind load zone 2 at altitudes up to 500 meters above sea level.

[0029] In a particularly advantageous embodiment, the solar table system consists of four support units, two main support units, and a plurality of module support units. This embodiment advantageously offers a total usable area of ​​more than 50, 60, or 65 square meters, or up to 70 square meters. Specifically, the total usable area of ​​the solar table system is approximately 68 square meters. This advantageously allows for a photovoltaic output of up to 15.5 kilowatt-peak, according to current standards. At the same time, the costs for the substructure can be around €1,200, including screws and transport to the construction site, making the system very cost-effective.

[0030] A photovoltaic system according to the invention comprises a previously described solar table system, wherein photovoltaic modules are mounted in the module carrier units. Preferably, the photovoltaic modules are mounted and, in particular, secured in the module carrier units. Further developments of the photovoltaic system will become apparent from the general description and from the description of the exemplary embodiment.

[0031] Further features and advantages of the exemplary embodiment of the invention are described below with reference to the drawings. The same reference numerals are used for identical or similar parts and for parts with identical or similar functions.

[0032] It is not necessary for a solar table system according to the invention to have all the features described below. It is also possible for a solar table system according to the invention to have only individual features of the embodiment described below.

[0033] Fig. Figure 1 shows a schematic side view of an embodiment of a photovoltaic system 101 according to the invention, comprising a solar table 100 with support unit 1, main support unit 3, and module support unit 4. Several photovoltaic modules 102 are securely mounted on the module support units 4. The inclination of the photovoltaic modules 102 and the photovoltaic system 102 is predetermined to enable optimal electrical energy yield.

[0034] The support unit 1 comprises supports 11 and ground supports 12. The supports 11 are inserted into the ground supports 12. The height of the supports 11 can be adjusted using adjustment units 13. This also allows for the compensation of uneven ground 2 on the underlying surface. Furthermore, the inclination 1021 of the photovoltaic modules 102 can be adjusted. The ground supports 12 are driven into the ground 2 of an agricultural area, such as a field. The support units 1 transfer a load into the ground 2.

[0035] The main support units 3 comprise main beams 31, which here rest on two supports 11. The main beam 31 has an asymmetrical main beam profile 311 and is slipped over a distal end 114 of the support 11 of the support unit 1. The main beam profile 311 includes a section that forms an opening, similar to a C-profile.

[0036] Module carriers 41 of the module carrier unit 4 are attached to the main carriers 31. The photovoltaic modules 102 are mounted in the module carriers 41.

[0037] The solar table provides a minimum height B of 2.10 meters, allowing for agricultural cultivation of the land beneath it. The Solar Table 100 has a span S of 4 meters between its supports, ensuring that the support units 1 have minimal impact on the use of the agricultural land 2.

[0038] Fig. Figure 2 shows a schematic top view of the photovoltaic system 102 with the solar table 100. Four support units 1 are present. Main beams 31 of main beam units 3 are mounted on two of the support units 11. The module carriers 41 of the module carrier units 4 are attached to the main beams 31. The photovoltaic modules 102 are located in the module carriers 41. Due to the asymmetrical shape of the main beam profile 311 of the main beam 31, it has a length 314 of approximately 10 meters. Thus, the solar table 100 provides a total area of ​​approximately 68 square meters, while simultaneously ensuring the cultivation of the soil 2 beneath the photovoltaic modules 102.

[0039] Fig. Figure 3 shows a schematic perspective view of part of the solar table 100 with a connecting unit 5 and a fastening unit 6.

[0040] The connecting unit 5 is located between the main beam 31 and the support 11. The connecting unit 5 comprises connecting elements 51, which are designed here as screws with a nut each, and compensating elements 52, which are designed here as elongated holes 52 in the support 11 and the main beam 31. The compensating elements 52 allow for tolerances during assembly. The elongated holes on the supports 11 and the main beam 31 extend transversely to each other, thus providing maximum flexibility. Advantageously, this allows the main beam 31 to be slipped onto the distal ends 114 of the supports 11 during assembly and then initially fixed by the connecting element 51. The main beam can then be horizontally aligned with the support 11 before, for example, a screw connection is fully tightened.

[0041] The module carrier 41 of the module carrier unit 4 is attached to the main carrier 31 by the fastening unit 6. The fastening unit 6 comprises fastening elements 61, which also include an elongated hole 61 to enable optimal alignment of the module carrier 41 with the insertion receptacles 411.

[0042] Fig. Figure 4 shows a schematic sketch of a cross-section of a main support profile 311 of a main support 31 of a main support unit 3 of the solar table 100. The main support profile 311 is asymmetrically designed here and has two legs 312 and a base 313. The angle between the legs 312 and the base 312 is always other than 90 degrees. The inclination of a section of the base 313 determines the inclination 1021 of the photovoltaic modules 102, since the module supports 41 are directly attached to it.

[0043] At the ends of the legs 312, outward-facing bends are present, which extend outwards from the legs 312 in a V-shape, so that they lie outside the projection surface of the base 313. This further improves the stiffness of the main beam 31. Furthermore, the bends can be used as cable receptacles for the connection cables of the photovoltaic modules 102.

[0044] The asymmetrical design of the main beam profile 311 of the main beam 31 is adapted to the asymmetrical load case. Therefore, a profile thickness of 2 millimeters for the main beam profile 311 is sufficient to permanently support the load.

[0045] Fig. Figure 5 shows a schematic top view of the main girder profile 311 of the main girder 31 of the main girder unit 3.

[0046] Fig. Figure 6 shows a first schematic perspective view of the main girder profile 311 of the main girder 31 of the main girder unit 3. The connecting elements 52, designed as elongated holes 52, are shown here extending along the main girder profile 311 of the main girder 31. Since the connecting elements 52 extend transversely to this in the supports 11, see Fig. 3. Tolerances and distances during assembly can be compensated for particularly well.

[0047] Fig. Figure 7 shows a second schematic perspective view of the main girder profile 311 of the main girder 31 of the main girder unit 3.

[0048] Fig. Figure 8 shows a schematic sketch of a module support profile 411 of a module support 41 of a module support unit 4 of the solar table 100. The module support profile 413 is symmetrically designed and has two insertion recesses 411 for the photovoltaic modules 102. In the inserted state, the photovoltaic modules 102 are positively engaged and at least partially enclosed on three sides. Advantageously, the photovoltaic modules 102 can be easily inserted into the insertion recesses 411 of two adjacent and spaced-apart module supports 41 after their assembly. The photovoltaic modules 102 can then be secured to the locking units 412, which are designed here as bending tabs 412, by simply bending them.

[0049] Fig. Figure 9 shows a schematic sketch of the module support profile 413 of the module support 41 with a locking unit 412. The locking units 412 are inserted longitudinally into the profile 413 as bending tabs 412. After a photovoltaic module 102 has been inserted, the bending tabs 412 can simply be folded over, thus securing the photovoltaic modules 102 in their current position. This eliminates the need for module clamps or similar devices to fasten the photovoltaic modules 102.

[0050] Fig. Figure 10 shows a schematic view of the module carrier profile 413 of the module carrier 41 from below with the fastening element 61 of the fastening unit 6 designed as an elongated hole 61 and the tabs 412 of the securing unit 412.

[0051] Fig. Figure 11 shows a schematic perspective view of the module support profile 413 of the module support 41 of the module support unit 4.

[0052] Fig. Figure 12 shows a schematic sketch of a support profile 111 of a support 11 of a support unit 1 of the solar table 100. The support profile 111 is designed as an open profile 111 with six bends and two legs 112 and a base 116 and an open side 113. The profile 111 has inward-facing bends 115, which are located within a projection surface of the base 116. The support profile 111 is very resistant to buckling.

[0053] Fig. Figure 13 shows a schematic view of the column profile 111 of the column 11 from above with the connecting unit 5 with the connecting elements 52. The connecting elements 52 are designed here as elongated holes 52, which extend along the column profile 111.

[0054] Fig. Figure 14 shows a schematic view of the support profile 111 of the support 11 of the support unit 1 from below.

[0055] Fig. Figure 15 shows a schematic perspective view of the column profile 111 of column 11 of column unit 1.

[0056] Fig. Figure 16 shows a schematic sketch of an earth support 12 of the support unit 1. The earth support 12 has the same support profile 111 as the support 11.

[0057] Fig. Figure 17 shows a schematic top view of the support profile 111 of the earth support 12.

[0058] Fig. Figure 18 shows a schematic perspective view of the support profile 111 of the ground support 12. The support profile 111 of the ground support 12 is slightly wider, allowing the support 11 to be inserted into the ground support 12. The height of the support 11 can be adjusted by means of the adjustment unit 12, which here comprises holes at various intervals from the end of the ground support 12, in order to compensate for unevenness in the ground 2 and to set an inclination 1021 of the photovoltaic modules 102.

[0059] Further features and characteristics that may be preferred are listed below: - Static suitability for wind / snow load zone 2, 500 m above sea level in Germany - Minimum height of the lower edge of the modules: 2.10 m above the ground - Module mounting without conventional module clamps - minimum required number of standardized fasteners - Maximum tolerance of the table to uneven terrain, inaccuracies of the measured driving points, positional deviations of the supports after driving (except plumb). - Total table costs under €100 / kiloWattPe - Eliminating terrain slopes through tolerantly connected building elements - To compensate for positional and directional deviations, which increase proportionally with long supports, - Simple assembly systems for fast and error-free construction - to consider occupational safety at high working heights and to revolutionize the module fastening process - to ensure the welfare of grazing animals under the modules through internal profile edges - to consider the subsequent cabling process and to plan cable laying platforms into the profile contours Reference symbol:
