Description

Carrier system for arranging a photovoltaic unit having at least one

Photovoitaikmodul

The invention relates to a carrier system for arranging a photovoltaic unit, comprising at least one photovoltaic module for generating energy, in particular electricity, the carrier system comprising at least a first carrier element and a second carrier element, which are designed to arrange the photovoltaic module, the

Carrier elements are arranged at a distance from one another and each have at least one support surface for arranging the photovoltaic module.

Photovoltaic units are known from the prior art which have a large number of photovoltaic modules for generating electricity. The photovoltaic modules are installed on a carrier system, the carrier system being at least a first

Carrier element and a second carrier element, which are arranged spaced apart and each have at least one support surface for the arrangement of the

Have photovoltaic modules. The photovoltaic modules are arranged inclined relative to a subsurface, in particular to a floor level. Here are the

Photovoltaic modules on the contact surfaces of the first carrier element and the second carrier element, so that the photovoltaic modules must be attached to the carrier elements. When assembling the photovoltaic modules, they are pushed or placed one after the other from bottom to top onto the respective support elements. When the photovoltaic module has reached its first position, a second fitter has to hold the photovoltaic module in the corresponding position, while the first mechanic uses a connecting element to screw the photovoltaic module to the carrier elements. Depending on the size and weight of the photovoltaic modules, several technicians must also hold the photovoltaic module to be fastened in position so that the first mechanic can securely connect it to the carrier elements using the connecting element. The disadvantage of this solution is that several fitters are required to install the photovoltaic unit. As a result, the installation costs for installing the photovoltaic unit, in particular the personnel costs, are unnecessarily increased.

It is therefore the object of the invention to provide an inexpensive carrier system which simplifies the assembly of the photovoltaic modules.

The object is achieved by claim 1, in particular by the

characterizing part of claim 1. It is provided that the first carrier element and the second carrier element each have at least one support element, which together form a first pair of support elements for a photovoltaic module, the respective support element being connected to the respective support surface and at least partially spaced apart from the respective support surface of the corresponding one Carrier element is arranged, wherein the photovoltaic module on at least two

Support elements is arranged at least temporarily and at least partially the

Counteracts gravity of the photovoltaic module. This measure makes it easier to assemble the photovoltaic modules. It is preferably only a single installer who arranges the photovoltaic module on the carrier system. The photovoltaic unit preferably has a plurality of photovoltaic modules. The carrier system can then also have a plurality of carrier elements, the number of carrier elements depending on the number of photovoltaic modules. The carrier elements are preferably arranged parallel to one another and arranged in a plane which is arranged inclined with respect to a vertical gravitational force. The support elements, which are preferably designed as a top-hat rail or C-profile, are mounted in such a way that they have a gradient, in particular a north-south gradient or an east-west gradient. The bottom photovoltaic module is at a lower height than the top photovoltaic module. Only one technician is preferably required for the arrangement of the photovoltaic modules, even if the photovoltaic modules have an increased weight of, for example, approximately 20 kg to approximately 50 kg. If the fitter is preferably used, it should be ensured that the fitter is also able to at least independently move and / or install a photovoltaic module, in particular to fasten it with the carrier system. When assembling the photovoltaic unit, a first photovoltaic module is first placed on a lowermost section of the first and second

Carrier element placed and is supported by a first pair of support elements such that slipping to a floor level is excluded. After that it will

Photovoltaic module moved by the fitter to a higher section of the support elements, where a second pair of support elements is arranged. When moving the

Photovoltaic module from one section to another section, the support elements of the other section are run over by the photovoltaic module until the photovoltaic module can be supported again on these support elements. The

Supporting elements of the respective section of the respective carrier element secure the photovoltaic module from slipping into an underlying section which is arranged at a lower height level or from slipping onto a surface. The photovoltaic modules are installed until an uppermost section of the carrier elements is reached. The highest support elements thus preferably secure the first photovoltaic module to be installed. By the

The support system according to the invention is therefore preferably only required by a fitter, as a result of which the assembly costs for the photovoltaic unit can be reduced because the support system has a simple construction. The assembly of the photovoltaic modules is also made considerably easier for the fitter because they take breaks can and at the same time the at least one photovoltaic module is held by the corresponding support elements at least two times in an intermediate position on the carrier elements. The support element, in particular a pair of support elements, is designed in such a way that it counteracts the gravity of the respectively supporting photovoltaic module. Furthermore, the support elements are arranged on the respective support element in such a way that the respective photovoltaic module is already arranged such that it can be attached essentially without further subsequent positioning with the support system, in particular with the support elements and / or other already installed photovoltaic modules. As a result, the assembly effort of the photovoltaic unit is further increased by the carrier system according to the invention

advantageously reduced.

According to a preferred embodiment of the carrier system, it can be provided that the first support element and the second support element are arranged opposite one another and in alignment with one another and form the pair of support elements. This measure advantageously ensures that the photovoltaic module can be held in a horizontal position by the support elements. Lateral slipping of the photovoltaic module is therefore impossible. The manufacture of the carrier elements can also be made more cost-effective because it is possible to

To be able to produce carrier elements as identical parts.

According to a further preferred embodiment of the carrier system, it can be provided that the first support element and the second support element are positively connected to the photovoltaic module during assembly and / or in the assembled state. The positive connection is guaranteed by supporting the photovoltaic module on the pair of support elements. The advantage is that when you support the

Photovoltaic module on the pair of support elements on additional connecting elements, such as screw connections can be omitted. Here are the

Support elements designed so stable that the gravity of the

Counteract photovoltaic module. When the photovoltaic module is moved from a pair of support elements to a pair of support elements arranged next to it higher, the positive connection between the one pair of support elements is released by moving the photovoltaic module to a higher level. It is therefore preferably possible to dispense with a further fitter if the

Photovoltaic unit is married to the carrier system.

The carrier system can be made very simple, inexpensive and stable if the carrier system comprises at least a first cross member and preferably a second cross member, at least the first cross member and preferably the second one Cross members are each designed for fastening at least the first support element and the second support element.

If the photovoltaic unit is to be arranged at a distance from a substrate, it can preferably be provided that the carrier system comprises at least one floor support which is connected at least to the first cross member and or the second cross member. The carrier system is preferably provided with four floor supports if it is arranged, for example, in a field. The floor supports ensure a stable and secure arrangement of the carrier system on the ground, especially in the field.

To ensure stable and secure support of the photovoltaic module on the respective

To be able to ensure pair of support elements, it can be provided that the

Support element is arranged with an angle of inclination Beta to a plane of the support surface. The angle beta is preferably 5 degrees to 60 degrees. The choice of this angle beta thus ensures, on the one hand, that the respective photovoltaic module can be supported securely on the respective pair of support elements without it independently moving to a lower height level and, on the other hand, when moving the photovoltaic module from a lower section of the respective one

Carrier element in a higher section of the respective carrier element

Photovoltaic module can be moved over the corresponding pair of supporting elements simply and with reduced effort over the pair of supporting elements of the higher section of the carrier element.

The production costs of the carrier system according to the invention can be considerably reduced if at least the first supporting element with the first carrier element and at least the second supporting element with the second carrier element are made in one piece and from the same material, preferably from metal. For the purposes of the invention, one-piece means that the at least one support element, in particular all

Support elements and the respective support element, in particular all support elements are formed from one component. For this purpose, the one preferably made of metal

Carrier element are punched out during the manufacturing process at the predetermined positions at which the support elements are to be provided. It may be advisable to punch out a rectangular U from the carrier element and then to deform, in particular to bend, the support element formed in the plane of the support surface by the stamping process. Alternatively, the at least one support element can also be arranged retrospectively on the carrier element, for example by being non-positively and / or positively and / or materially connected to the carrier element, in particular to the support surface of the carrier element. So that the support elements remain undamaged during assembly of the photovoltaic modules and maintain their positions, in particular their angle of inclination Beta with respect to the contact surface of the respective support element, it can be provided that the support elements are each rigid and inflexible. This is particularly the case if the support elements are made of metal, preferably of galvanized sheet metal or of aluminum. The thickness of the support element should preferably be in the range of 1 mm to 5 mm in order to prevent the support element from being bent unintentionally when the photovoltaic modules are being installed.

According to a further preferred embodiment of the carrier system, it can be provided that the support elements are closed, preferably with the support surface

Bulge are formed. The bulge extends out of the plane of the respective contact surface, with all side walls of the bulge without

Interruption with the respective contact surface are interconnected. The

Curvature can be produced by deforming, for example by a stamp of a deformation machine, in that the stamp presses the material to be deformed on a rear side of the support surface and thus forms a, in particular hill-like bulge, which can be designed like a ramp. In this case, an additional stamping process for producing the support element can be dispensed with.

The assembly of the photovoltaic modules and safe and reliable support of the photovoltaic modules can be provided if the support elements are each designed as a ramp. The effort required by the mechanic when installing the photovoltaic modules can be considerably reduced if the support elements are designed as a ramp. Furthermore, it can be expedient if the support elements, in particular the respective ramp, are each designed as preferably cuboidal tabs. The tabs should have a smooth and flat surface in order to reduce the frictional resistance when moving the photovoltaic modules from a section of the respective carrier element to a section of the respective carrier element which is at a higher level. A smooth surface of the ramp, in particular the tab, also has the advantage that the photovoltaic modules remain undamaged when the photovoltaic modules move over these support elements. The support element can also comprise a ramp, which has a curved and / or curved section at its preferably free end, to which a flat section adjoins. This flat section can preferably be arranged parallel or inclined to a respective bearing surface. With a ramp designed in this way, the forces acting on the support element, which arise from the support of the photovoltaic module on the support element, can be made even better be distributed on the support element, whereby the support system can be made more stable. The curved and / or curved section can at one on the

Support element acting load of the weight of the corresponding

Counteract the photovoltaic module so that if necessary, photovoltaic modules with a greater weight can be mounted on the carrier system.

According to a further preferred embodiment of the support system, it can be provided that each support element has at least one further support element, a distance L ′ of the support elements on the same support element being greater than / equal to a length L of a photovoltaic module. The distance L ′ of the support elements on the same carrier element is preferably equal to a length L of the photovoltaic module, because a gap or the distance between the individual photovoltaic modules can thus be reduced and preferably eliminated between the individual photovoltaic modules. This measure makes it possible to arrange the number of those on the carrier system

Increase photovoltaic modules. The distance L 'can be determined, for example, by the distance between the end of the ramp of the one support element and the start of the ramp of the closest support element on the same support element.

The stability of the carrier system can be further improved if the carrier element for each cross member has at least one cross member fastening section which is arranged between two adjacent support elements of the respective carrier element.

According to a further preferred embodiment of the carrier system, it can be provided that at least one connecting element is provided which is positively and / or non-positively connected to at least one photovoltaic module and is non-positively and / or positively, in particular with a screw, connected to a fastening section arranged on the carrier element , This measure enables the photovoltaic modules to be additionally secured against slipping, lifting and moving on the support system, in particular on the support elements. For this purpose, the photovoltaic modules can have recesses, in particular elongated holes, into which a connecting element can be arranged in a form-fitting manner, in particular in an insertable manner. The connecting element itself can be made of metal and is consequently rigid and inflexible. Furthermore, the connecting element can have a bore, preferably with a thread, into which a screw can be screwed. In addition, the support element then also has a bore, preferably with a thread, into which the screw is then also screwed in order to finally firmly and securely connect the photovoltaic module to the corresponding support element. Other types of connection are also possible, such as a Locking and / or jamming the photovoltaic module with the support system and / or the photovoltaic modules with one another.

In order to be able to arrange a plurality of photovoltaic modules on a support element, it can be provided that the respective support element has at least one first contact surface for a first row of at least one photovoltaic module and at least one second contact surface for a second row of at least one photovoltaic module, each contact surface having at least one Has support element. It may be advisable to design the carrier element as a hat profile or C profile. It can then be provided that the first contact surface and the second contact surface are arranged separated from one another by a guide web, the guide web being formed in one piece and from the same material, preferably from metal, in particular from strip-galvanized steel.

The carrier system according to the invention can also be provided with a photovoltaic unit, preferably by a fitter, if each photovoltaic module has its own weight of 20kg to 50kg.

In order to operate the photovoltaic unit with the greatest possible output, it can be provided that the respective carrier elements are each angled at an angle of inclination alpha to a surface, the angle alpha being 5 degrees to 35 degrees. The subsurface is to be seen as the floor level. This can be a meadow, a field or the like, for example. Carrier elements, which are arranged, for example, on a pointed roof of a house, are also angled to the ground, because in this case the ground is the level on which the house is arranged. In the sense of the invention, this means that the support elements always have a so-called north-south gradient or east-west gradient, so that without the

Supporting elements, the photovoltaic modules would independently move downward on the corresponding support elements due to their gravity and would eventually fall onto the ground, in particular onto the ground level.

FIG. 1 shows a carrier system 1 for arranging a photovoltaic unit 2 with, for example, fifteen photovoltaic modules 3a-3o. How to do well in Figure 2 can recognize, the carrier system 1 preferably has six, in particular parallel and spaced from each other vertically extending support elements 4a-4f, which are provided for the arrangement of the photovoltaic modules 3a-3o, the

Photovoltaic modules 3a-3o are designed to generate energy, in particular electricity. In the present exemplary embodiment it is provided that each photovoltaic module 3a-3o has a dead weight of approximately 30kg. Furthermore, the carrier system 1 has a first crossmember 5a and a second crossmember 5b, the first crossmember 5a and the second crossmember 5b each for fastening the Carrier elements 4a-4f are formed so that the carrier elements 4a-4f are each angled at an angle of inclination alpha to a substrate 6, the angle alpha preferably being 5 degrees to 35 degrees. The subsoil 6 can be, for example, a meadow or a field on which the carrier system 1 is arranged. The support elements 4a-4f, which are arranged, for example, on a pointed roof of a house, are also arranged at an angle to the subsurface 6, because in this case the subsurface 6 is the level on which the house is arranged. The carrier elements 4a-4f therefore have a so-called north-south gradient or east-west gradient. The carrier elements 4a-4f each have at least one crossmember fastening section for each crossmember 5a, 5b, which is arranged between two adjacent support elements of the respective carrier element 4a-4f.

The carrier system 1 further comprises four floor supports 7a-7d, the floor supports 7a, 7b being connected to the cross member 5a and the floor supports 7c, 7d being connected to the cross member 5b, in particular non-positively and / or positively. The floor supports 7a-7d stand on the base 6, so that the photovoltaic unit 2 is spaced apart from the base 6. Furthermore, in the present case, the carrier system 1 comprises thirty support elements, with only the support elements 1 a,

1 1 b of the carrier element 4b and the support elements 12a, 12b of the carrier element 4c is discussed in more detail in order to explain the advantages of the carrier system 1 according to the invention.

FIGS. 3 to 5, for example, visualize the carrier element 4b in more detail, which can preferably be designed as a top-hat rail. The carrier element 4b comprises a first contact surface 8 and a second contact surface 9, which are arranged separated from one another by a guide web 10, the guide web 10 being formed in one piece and from the same material, preferably from metal, in particular from galvanized steel. The first contact surface 8 is provided for a first row of photovoltaic modules 3a-3c and the second contact surface 9 is for a second row of

Photovoltaic modules 3d-3f provided. Furthermore, the carrier element 4b

Support elements, which are arranged on the support surface 8 and support elements, which are arranged on the support surface 9. Basically everyone serves Supporting elements of the carrier system 1 for arranging the photovoltaic modules 3a-3o. The carrier elements 4c-4e have the same structure as the carrier element 4b, so that consequently each carrier element 4c-4e likewise comprises six supporting elements. The carrier elements 4a, 4f are arranged on the edge of the carrier system 1 and therefore preferably each comprise three supporting elements. Alternatively, the carrier elements 4a, 4f can also be designed in exactly the same way as the carrier elements 4b-4e, so that the carrier elements 4a, 4f preferably each comprise six supporting elements.

All support elements of the carrier system 1 are arranged with an angle of inclination Beta to a plane of the respective bearing surface 8, 9, the angle Beta being 5 degrees to 60 degrees.

All thirty support elements of the carrier system 1 are preferably made in one piece with the respective carrier element 4a-4f and are made of the same material, preferably of metal, the thirty support elements or alternatively thirty-six

Support elements are each rigid and inflexible. This means that

Photovoltaic modules that can have up to 50kg dead weight, can be supported on the respective support elements without the respective support elements being plastically deformed.

As can be clearly seen in FIG. 7, the support element 11b is designed as a ramp, the support element 11b, in particular the ramp, in each case being designed as a preferably rectangular lobe. All support elements of the

Carrier systems 1 preferably have the same configuration as the support element 11b shown in FIG.

The support element 3b shown in more detail in FIGS. 3 to 5 has the three support elements on each support surface 8, 9, of which the support elements in FIG. 6d, for example

Support elements 1 1 a, 1 1 b are visualized on, which are arranged horizontally spaced from one another on the respective support surface 8, 9. The distance L ’adjacent

Support elements in the vertical direction (north-south or east-west) to one another on the same support element 4a-4f, in particular on the respective contact surface of the corresponding support element 4a-4f, are greater / equal to a length L of the respective photovoltaic module 3a-3o.

The carrier elements 4b-4e are preferably of identical design. The carrier elements 4a, 4f should each have only one contact surface, because the carrier elements 4a, 4f are arranged on the edge of the carrier system 1 and consequently only have to carry a number of photovoltaic modules, in particular the series 3a-3c and 3m-3o.

In order to mount a photovoltaic module 3a-3o, two adjacent carrier elements, for example the carrier elements 4b, 4c, are preferably required. The invention is further described using the example of the carrier elements 4b, 4c. The carrier element 4c also has six support elements, of which support elements 12a, 12b are visualized in FIG. 6d, for example, and two support surfaces 13, 14 and a guide web 15. It is pointed out that the carrier element 4c preferably has the same structural design as the carrier element 4b. The carrier element 4b and the carrier element 4c thus each have six support elements.

The support element 11b of the support element 4b and the support element 12a of the

Carrier element 4c together form a first pair of support elements for the

Photovoltaic module 3f, wherein the respective support element 11b, 12a is connected to the respective support surface 9 or 13 and is at least partially spaced apart from the respective support surface 9, 13 of the corresponding support element 4b, 4c. In this case, the photovoltaic module 3f is permanently arranged on the two support elements 11b, 12a for operation, which together are the gravity of the photovoltaic module 3f

counteract. The support element 11b of the support element 4b and the support element 12a of the support element 4c are arranged opposite and in alignment with one another on a horizontally running straight line and form the respective support element pair. The support element 11b and the second support element 12a are positively connected to the photovoltaic module 3d or 3e or 3f during assembly and / or in the assembled state. To fasten the photovoltaic modules 3a-3o, connecting elements are provided which are positively and / or non-positively connected to at least one

Photovoltaic module 3a-30 are connected, in particular with a screw, and which can additionally be non-positively and / or positively connected to a fastening section arranged on the carrier element 4a-4f.

Below is the assembly of the photovoltaic modules 3d, 3e, 3f on the two

Carrier elements 4b, 4c described in more detail.

In a first step, this is preferably done by a mechanic

Photovoltaic module 3d on the support surface 9 of the support element 4b and on the

Support surface 13 of the carrier element 4c arranged. The preferably only fitter first pushes the photovoltaic module 3d vertically up until that

Photovoltaic module 3d with its lower side, with respect to the substrate 6, having the support elements 11b, 12a at times on the first pair of support elements and at times being supported in the process. The installer then pushes the 3d photovoltaic module to the next higher level, up to the next pair of support elements. Here too, the photovoltaic module 3d comes into contact temporarily and is supported on the corresponding support elements. The fitter then pushes the photovoltaic module 3d to the next higher level, in particular the highest level relative to the base 6, where in the present case it has reached its end position and is then supported on the corresponding support elements. After that, you can then the next photovoltaic module 3e are mounted according to the same principle, so that the photovoltaic module 3e is supported in its end position by the pair of supporting elements which is at the next higher level of the pair of supporting elements

Support elements 1 1 b, 12a is arranged. Then the photovoltaic module 3f is still mounted according to the same principle, the photovoltaic module 3f then being permanently supported on the support elements 11b, 12a in its end position. Then the

Photovoltaic modules 3d-3f preferably connected to the adjacent photovoltaic modules 3a-3c and 3g-3i and / or preferably to the corresponding carrier element 4b, 4c with the aid of connecting elements, such as for example the connecting element 16 shown in FIG. 6b, in a positive and / or non-positive manner , especially screwed. FIG. 8 shows an alternative embodiment of a carrier element 20 for the carrier system 1 according to the invention, which is identical in terms of the materials and the construction of the support elements from the exemplary embodiment described above. The carrier element 20 also has a plurality of support elements 21 a-21 d. The carrier element 20, however, has only a single support surface 22 on which the respective photovoltaic modules 3a-3o can be arranged. For example, the carrier element 20, preferably also the carrier elements 4a-4f described in the first exemplary embodiment, can also be arranged on an already existing carrier system having a receiving carrier. For this purpose, the carrier element 20 or the carrier elements 4a-4f according to the embodiment described above could be applied to the

Recording carrier, which can be part of the carrier system 1, in particular

Connect non-positively and / or positively, preferably push on or push on.

FIGS. 9a-10b show sections of alternative carrier systems 100 which differ from one another and which differ in particular in the design of the supporting elements 110 used. The basic structure of these alternative carrier systems 100 corresponds to at least one of the previous ones

carrier systems 1 described in FIGS. 1 to 8.

A first alternative carrier system 100 is visualized in FIGS. 9a and 9b, which comprises a support element 110 designed as a ramp. The ramp has at its end a curved and / or curved section 1 1 1, to which a flat section 1 12 connects. This flat section 1 12 is inclined to a respective one

Support surface 800 arranged, wherein a lower section 11 13 of the flat section 1 12 touches or at least partially penetrates a plane 810 of the support surface 800. Below the lower subsection 1 13, the support surface can therefore have a cutout 812, which was created during the production process when the support element 1 10 was formed. A second alternative carrier system 100 is visualized in FIGS. 10a and 10b, which comprises a support element 110 designed as a ramp. The ramp has at its end a curved and / or curved section 1 1 1, to which a flat section 1 12 connects. This flat section 112 is arranged inclined to a respective bearing surface 800, a lower partial section 113 of the flat section 112 being spaced apart from a plane 810 of the bearing surface 800. Below the lower section 1 13, the support surface can have a recess 812, which was created during the production process when the support element 1 10 was formed.

The support elements e 1 10 described in FIGS. 9a-11b can also be used for the previously described carrier systems 1.

Alternative configurations of the carrier system 1 are possible. So they can

Supporting elements of the carrier system 1 can also be designed to be flexible and movable, so that they preferably move in the direction of the bearing surface of the respective carrier element 4a-4f if, for example, the photovoltaic modules move when the

Cross or slide over the support elements. Moving the respective photovoltaic module to a next higher level is thus simplified because, for example, the frictional resistance between the respective supporting element and the respective photovoltaic module is reduced by at least partially sinking the supporting elements into their respective contact surface.

It is also conceivable that the support elements are designed as a bulge, preferably closed with the support surface 8, 9, 13, 14. The stretches

Bulge out of the plane of the respective bearing surface 8, 9, 13, 14, all side walls of the bulge being connected to one another without interruption with the respective bearing surface 8, 9, 13, 14. The bulge can be produced by deforming, for example by means of a stamp of a deformation machine, in that the stamp on a rear side of the support surface 8, 9, 13, 14 presses the material to be deformed upward and thus forms a, in particular hill-like bulge, which is ramp-like can be.
