Description

To convert solar energy into usable forms of energy, solar modules are used, which are typically either photovoltaic modules or solar collector modules. Photovoltaic modules convert incidental sunlight into electrical energy, while solar collector modules heat incoming fluid in passing sunlight. In practice, a plurality of solar modules are usually arranged on a common support device in order to anchor them to the ground or to a building and to orient them in the desired manner to the sun. The support devices must be able to withstand large temperature fluctuations, weathering and sometimes enormous wind loads in practice. The available on the market support devices can often be provided only with a large material and cost due to their design. This is also disadvantageous in terms of transport costs, especially since the solar module arrangements are increasingly being used in remote but sunny areas. The support devices are often assembled on site from individual components that are easier to transport.

It is therefore an object of the invention to provide a solar module assembly, a cross member for such a solar module assembly and a solar module system, which require the least possible use of material and thus can be generated more cheaply and transported to the place of use.

The object concerning the solar module arrangement is achieved by a solar module arrangement according to patent claim 1. The traverse according to the invention is specified in claim 9. The solar module system according to the invention has the features specified in claim 10. Preferred embodiments of the invention are specified in the subclaims and in the description.

The solar module assembly according to the invention has a plurality of solar modules, which are arranged one behind the other in a row arranged on a common support device. The support device comprises a 3-point cross-member with a total of three edge-plate profiles, which are spaced apart from one another and extend parallel to one another in each case in the direction of the longitudinal axis of the 3-point crossbeam. A first and a second edge plate profile are each supported on truss rods on the third edge plate profile. The solar modules are mounted directly on the first and the second edge plate or on transverse profiles, which are each spaced along the 3-point truss and are mounted parallel to each other on the first and the second edge plate profile lying parallel. The 3-point crossbeam can be realized on the one hand with a particularly low material usage. This offers advantages in terms of material costs as well as the mass of the 3-point crossbar. On the other hand, this can be minimized overall transport costs incurred during the transport of the 3-point truss. In addition, the 3-point truss can be manufactured easily and with simple technical means due to its structural design and the possibility of using a large number of identical parts. It should be noted that the 3-point crossbeam can be transported disassembled to the place of use in the sense of a kit. This also allows the transport volume to be minimized and resort to conventional means of transport. Overall, the solar module assembly can be provided by this world particularly cost. The 3-point truss can be realized with a sufficiently large load capacity, regardless of their lightweight construction. As a result, the solar module arrangement offers a wide range of applications and can be used without difficulty even in regions where increased wind or snow loads are to be expected. The three-point cross member may, preferably in total, be made of a corrosion-resistant material, in particular galvanized steel sheet.

The first and the second sash plate profile are preferably fastened to each other over a majority of the longitudinal extent of the 3-point cross-member in a plane defined by this plane solely by the solar modules or the cross member. This makes it possible to keep the construction of the 3-point crossbeam particularly simple, which simplifies the assembly of the crossbeam and can be accomplished with simple means. This offers advantages, in particular during assembly of the 3-point crossbeam at the point of use or installation of the solar module arrangement.

According to a particularly preferred embodiment of the invention, the three edge-plate profiles each have a U-shaped or a V-shaped cross-section with two legs, which are connected to one another, preferably flat running, back portion of the respective edge plate profile. The squared-plate profiles can thereby be produced with a low material input and still be provided with a sufficiently large flexural rigidity. The back section also provides a sufficiently large support surface for supporting the solar modules or the intermediately arranged transverse profiles.

The cross sections are preferably designed according to the invention in each case as hollow profiles. The cross sections can be realized with low mass with a high bending stiffness. Alternatively, the transverse profiles can be designed as open edge profiles with a U, V or C-shaped cross-sectional shape or, for example, as DIN rail profiles. As a result, the material used for the 3-point traverse can be further reduced with a sufficiently large load capacity of the cross sections.

The transverse profiles can be welded according to the invention with the first and with the second edge plate profile in each case. As a result, a permanent and highly resilient attachment of the transverse profiles is achieved on the edge plate profiles.

If, according to a preferred embodiment of the invention, the transverse profiles protrude outward in the direction of their longitudinal extension beyond the outside of the first and / or second sash profile, this can provide a further enlarged mounting surface for the solar modules. The transverse profiles form cantilevers in this embodiment, so that the functional surface of the solar module arrangement serving for the use of solar energy can be increased without significant additional costs.

The transverse profiles are preferably designed as rectangular profiles and lie with their underside, preferably edgewise, directly on the back portion of the two edge plate profiles. As a result, a particularly large load-bearing capacity of the transverse profiles can be achieved with a simple structural design and sufficient support of the solar modules over the entire length of the transverse profiles can be ensured. Such Rectangular profiles are available on the market as a yard commodity cost and only need to be cut to the specified length of the cross sections.

The first and second sash plate profile may have projections and / or recesses in the longitudinal direction at their back section, into which recess complementary recesses or a complementary projection of a respective transverse profile engages. As a result, the assembly of the 3-point crossbeam can be further simplified and accelerated. The projections or indentations are preferably embossed into the respective component. As a result, cutting edges in the material of the respective component can be avoided, which are often problematic in terms of corrosion resistance of the components.

The three-point cross member preferably has at its opposite end sections in each case a bearing device with an axle piece or a hub, via which the cross member can be arranged pivotably on a vertical support anchored in the floor or on a building.

The bearing device according to the invention is preferably attached to all three edge plate profiles, so that they are fixed by the storage device relative to each other distance-invariant. In this design, the 3-point crosshead can thus be reinforced even further by the storage facility itself.

The traverse according to the invention is inexpensive and easy to manufacture and easier to handle due to their lightweight construction. As a result, at the same time the safety at work when handling the 3-point truss can be further improved. In addition, the 3-point crosshead can be provided with a sufficiently large load capacity for holding solar modules. The 3-point crossbeam can be transported as a kit to their place of use in view of their transport costs and assembled there with the simplest technical means. This can be done for example by welding or riveting of the individual components.

The solar module system according to the invention has a plurality of the aforementioned solar module arrangements, which are arranged in a row one after another in a row. The three-point trusses of two directly successive solar module arrangements can be mounted on the bearing devices of their end sections facing each other on one, preferably the same, vertical support.

Most preferably, at least part of the 3-point trusses are synchronously and in the same direction about their respective pivot axis adjustable by motor. In this embodiment, the angle of attack of the solar modules relative to the horizontal can be adapted to the respective position of the sun.

Further advantages of the invention will become apparent from the description and the drawings.

The invention will be explained in more detail with reference to exemplary embodiments shown in the drawing. The embodiments shown and described are not to be understood as exhaustive enumeration, but rather have exemplary character for the description of the invention.

Each solar module arrangement 12 includes a variety of solar modules 16 , The solar modules 16 are in a row 14 one after the other lined up on a common support device 18 arranged. The carrying device 18 includes a lightweight traverse, which is in the form of a 3-point crossbeam 20 is trained. The 3-point trusses 20 are each on a vertical support 22 stored. The vertical support 22 can be anchored in a manner not shown in detail in the ground or on a building. According to 1 can the 3 point trusses 20 two immediately adjacent solar module assemblies 12 with their end sections facing each other 24 each at the same, vertical support 22 be stored. For aligning the solar modules 16 on the respective position of the sun, the solar module arrangements 12 with a suitable drive 26 be provided, through which the respective 3-point cross member is pivotable about a pivot axis. The 3-point trusses 20 several solar module arrangements 12 can be coupled with each other, ie collectively, by a common drive 26 be adjustable.

2 shows a first embodiment of a 3-point crossbeam 20 for the in 1 shown solar module assemblies 12 in a perspective detail view. The 3-point crossbeam 20 comprises a total of three folded sheet metal profiles 28 . 30 . 32 which are arranged spaced from each other. The folded sheet metal profiles 28 . 30 . 32 are arranged parallel to each other and each extending axially in the direction with 34 designated longitudinal axis of the 3-point crossbeam 20 , Each sash plate profile 28 . 30 . 32 has a U-shaped or V-shaped cross section with a first and a second leg 36 , on, over a back section 38 connected to each other. The back sections 38 the first and the second edge plate profile 28 . 30 are each executed plan. A plane spanned by the first and the second edge plate profile is with 40 designated. On the back sections 38 There are several cross profiles 42 on. The cross sections 42 are along the 3-point crossbar 20 each spaced from each other and parallel to each other on the first and second edge plate 28 . 30 attached. The cross sections are preferential meadow with the two edge plate profiles 28 . 30 welded. The cross sections 42 are according to 2 to the first and second sash plate profile 28 . 30 each arranged orthogonally running. The cross sections 42 are each designed as hollow profiles, here as so-called rectangular profiles. It should be noted that the cross sections 42 with regard to their load capacity advantageously upright on the back sections 38 the two folded sheet metal profiles 28 . 30 issue. The cross sections 42 From a cost point of view as well as a simple installation of the 3-point truss, all are identical. At the in 2 embodiment shown close the cross sections 42 each flush or substantially flush with the outsides 44 the first and the second edge plate profile 28 . 30 from. The first and the second sash plate profile 28 . 30 are here over much of the longitudinal extent of the 3-point crossbar in the plane 40 solely through the cross sections 42 attached to each other.

For supporting the first and the second edge plate profile 28 . 30 and therefore for stiffening the 3-point crossbeam 20 serves the third square plate profile 30 , The third folding sheet metal profile 30 is each about trusses 46 on the first and on the second sash plate profile 28 . 30 attached. In the illustrated embodiment of the traverse is the third edge plate profile 32 shorter than the other two folded edge profiles 28 . 30 , but otherwise identical to these.

The trusses 46 are with the respective sash plate profiles 28 . 30 . 32 preferably welded, to ensure a durable and resilient connection of the components. The trusses 46 For example, they can be designed as folding sheet or as sheet metal bars. It should be noted that every truss staff 46 on the outside on the respective edge plate profiles 28 . 30 . 32 welded to maximize the snapshot power of the 3-point crosshead.

The 3-point crossbeam 20 points at their opposite end portions 48 each a storage facility 50 with an axle piece 52 on, about the 3-point crossbeam 20 rigid or hinged to an in 1 shown vertical support 22 or another suitable bearing part can be stored. The axle piece 52 is here designed as a hollow profile and can thus be formed for example from a rolled profile sheet.

The storage facility 50 is on all three edging profiles 28 . 30 . 32 fastened so that these in addition by the storage facility 50 are fixed relative to each other distance-invariant. This allows the traverse to absorb shear and bending stresses without significant deformation. According to an embodiment not shown in detail in the drawing, at least one of the two storage facilities 50 the 3-point crossmember 20 instead of the axle piece have a hub which is used to receive an axle piece of a vertical support 20 is trained.

In 3 is the 3-point crossbeam 20 shown in a side view. The trusses 46 are to the folded sheet metal profiles 28 . 30 . 32 at which they each attack, each at an angle α with 35 ≤ α ≤ 55 °, here from about 45 °, arranged obliquely. The nodes 54 the truss rods are in the axial direction at the same height with a contact area 56 the cross sections 42 with the first / second folding plate profile 28 . 30 , According to 3 has the storage facility 50 support struts 58 on, through which the axle piece 52 is strutted in the radial direction.

In 4 the 3-point crosshead is shown in a frontal view. The struts 58 each extend on the outside of the axle piece 52 in one to the longitudinal axis 34 the 3-point crossbeam 20 radial direction away.

In the 5 and 6 is a second embodiment of the 3-point crosshead 20 shown, which differs from the above in the 2 to 4 shown embodiment differs in that the cross sections 42 laterally over the respective outside 44 the first and the second edge plate profile 28 . 30 extend to the outside. This forms the cross profiles 42 lateral outriggers 60 , through which a larger absorption capacity, thus mounting surface, for the solar modules 16 ( 1 ) can be provided. This can be compared to the traverse according to 2 - With the same size of the solar modules 16 - a larger number of solar modules 16 be arranged on the 3-point traverse, in particular multi-row, as in 5 is shown. Overall, therefore, a larger module area can be realized.

After an unspecified reproduced in the figures embodiment of the 3-point crosshead 20 can the solar modules 16 also directly, ie without the interposition of the cross sections 42 , on the first and second square profile 28 . 30 be arranged and attached. The first and the second sash plate profile 28 . 30 are in this case over much of the longitudinal extent of the 3-point crossbar in the plane 40 solely by solar modules 16 attached to each other. With this type of construction, the in 2 shown cross sections 42 , whereby the 3-point traverse can be provided with a further minimized material use and thus more cost-effective.
