Description

The invention relates to a stabilizing element for photovoltaic modules or solar thermal modules, a photovoltaic module and a solar thermal module.

Photovoltaic modules and solar thermal modules in various embodiments have heretofore been known. These photovoltaic modules or solar thermal modules are subject to various safety requirements. These security requirements include u. a. the examination of the mechanical load capacity under the influence of weathering and other external influences. For example, the behavior of the photovoltaic module under the load of wind, snow, ice, rain or other static load by compression and tensile tests are tested within the scope of this mechanical load test.

In this case, different requirements are made depending on the region in which the photovoltaic module is to be used. For use in temperate climatic regions, these tests are carried out with compression and tensile tests at a load of 2,400 Pa, ie 240 kg / m ² . On the other hand, these compression tests are carried out at a load of 5,400 Pa, ie 540 kg / m ² , and tensile tests at 2,400 Pa, ie 240 kg / m ² if the photovoltaic modules are to be used in regions with increased wind, snow and ice loads.

In reality, these loads, which the photovoltaic modules have been tested for, can be exceeded by excessive snow loads and damage can be caused to existing systems. As a result of progressive climate change, it is to be expected that these too high burdens will continue in the future. Thus, an increase in the load limits in the testing of photovoltaic modules for the future by statutory regulations or industrial standards can be expected and urgently required. As a result, future photovoltaic modules will be able to meet future test requirements through a more stable design and thus also withstand the weather conditions. At the same time, there is a growing demand for manufacturers of solar modules to cut costs further in order to remain competitive.

However, existing photovoltaic modules are only tested for the previous load requirements, which have since proven to be insufficient. In order to continue to use them and to prevent their expected damage due to excessive weather loads, they can be made more stable by retrofitting of support elements. Hereby have various manufacturers z. B. started by support rails.

Allen support beams described above for photovoltaic modules or solar thermal modules is common that these support rails are not technically mature and therefore not cause the desired success and even damage to the back of the photovoltaic modules, and thus destroy them. Furthermore, supporting elements are known, which can not even be attached to the photovoltaic modules due to their strong cost orientation or lose their function even at low load. The known support rails are usually provided only for the modules of the respective manufacturer and can not be used universally in the modules of other manufacturers.

The invention is therefore based on the object to provide a simple, cost-effective and safe stabilizing element for photovoltaic modules and solar thermal modules that can be easily retrofitted regardless of manufacturer for existing photovoltaic modules and solar thermal modules.

This object is achieved by a stabilizing element for photovoltaic modules or solar thermal modules according to claim 1 and by a photovoltaic module according to claim 6 and a solar thermal module according to claim 7.

An advantage of the stabilization element according to the invention for photovoltaic modules and solar thermal modules is that it can be retrofitted very flexibly with existing modules. Thus, the construction is kept very simple and flexible in order to adapt to the existing and used modules of different manufacturers, without having to change or damage them.

This is done on the one hand by the flexibility of the design of the connection between the elements of the stabilizing element and the frame of the photovoltaic module. So z. B. holes are provided on the elements of the stabilizing element according to the invention in each case so that they match with the already existing manufacturer holes, holes or other openings in the context of the respective photovoltaic module, thereby to produce the mechanical connection between the stabilization element and photovoltaic module.

On the other hand, by extending the displaceable elements, the length of the stabilizing element according to the invention can be adjusted flexibly and steplessly, depending on the size of the Frame of the existing photovoltaic module or solar thermal module that is to be stabilized. This possibility for changing the length of the stabilizing element according to the invention for photovoltaic modules or solar thermal modules is also advantageous for the transport, since the stabilizing element can be pushed together to its minimum length and transported so as to save space. Furthermore, the displaceable elements of the stabilizing element according to the invention in this collapsed state can be very easily secured against unwanted slipping apart during transport. Finally, it is advantageous if not even essential for the assembly that the stabilizing element according to the invention can be inserted in the collapsed state in the frame of the photovoltaic module and only pulled apart there, depending on the design of the existing photovoltaic module jamming or tilting during the To avoid mounting or even to have access to the holes in the frame of the photovoltaic module.

It is also advantageous that the stabilizing element according to the invention for photovoltaic modules or solar thermal modules can be mounted by a single person. This is achieved by its simple and compact construction. Thus, the stabilization element according to the invention can first be attached to one side of the frame of the photovoltaic module after attaching the main carrier on the back of the module, then pulled out and then attached to the other side of the frame. Measures on the photovoltaic module such. As the attachment of additional holes are not required. This makes its installation very easy. Furthermore, damage to the photovoltaic modules or solar thermal modules can be avoided.

It is also advantageous that a plurality of stabilizing elements according to the invention can be mounted on a single photovoltaic module, as far as the frame of the photovoltaic module of the respective manufacturer provides sufficient space and connection possibilities for this purpose. So photovoltaic modules that are only to be stabilized against low loads, with z. B. only be retrofitted a stabilizing element according to the invention. However, if a photovoltaic module is exposed to a heavy load, it is also possible to retrofit several stabilizing elements according to the invention on the same photovoltaic module, if necessary also in several steps, if a retrofit that has been made proves to be inadequate in hindsight.

Furthermore, it is advantageous that the stabilizing element according to the invention can optionally be retrofitted. Thus, the purchaser of a photovoltaic module or a solar thermal module can opt for a type and manufacturer of photovoltaic modules, which has been tested for normal loads, and any number depending on the weather conditions in which the photovoltaic module is to be used Retrofit stabilizing elements according to the invention. As a result, no additional costs are incurred in areas without increased load. The additional costs for the stabilizing elements according to the invention in areas with increased load are justified by the increased service life of the stabilized photovoltaic modules and pay off over the life of the plants.

Finally, it is advantageous that the stabilizing element according to the invention is manufacturer-independent and can thus be produced and offered in larger quantities at low cost. On the other hand, the costs of manufacturer-specific stabilization solutions, which can only be used with their own photovoltaic modules, are always more expensive. Due to the low cost retrofitting is more attractive, so that the stabilizer elements according to the invention by the operator of a vulnerable to excessive exposure photovoltaic module rather used and thus the security of supply for the operator is increased by avoiding damage to his photovoltaic module.

According to one aspect of the invention, the device and the rear side of the photovoltaic module are connected together by gluing. This is advantageous because the back of a photovoltaic module i. A. no brackets, openings or holes, etc., via which a mechanical connection could be made to a stabilizing element. Furthermore, a photovoltaic module or a solar thermal module can not be drilled to provide an assembly or connection option, as this would damage the photovoltaic module or solar thermal module. Therefore, it is advantageous to stick the stabilizing element according to the invention on the back of the photovoltaic module, since this eliminates the need for a mechanical connection, for. B. a screw, deleted. Both tensile and compressive forces can then be transmitted from the photovoltaic module or solar thermal module to the stabilizing element according to the invention and partially compensated for via this adhesive connection. Depending on the adhesive material used, this compound can also be released again, should stabilization no longer be desired or required later. Furthermore, a stabilizing element according to the invention can, after its removal and renewal of the adhesive layer in another Photovoltaic module can be reused to save costs.

According to another aspect of the invention, the first element and the second element each have a structure (positive and negative) in the axial displacement direction. These structures, such as gears, waves or stripes interlock. As a result, loose and play between the first and second elements are minimized and a large contact surface between the two elements is achieved in order to achieve a high stability over the entire length of the stabilizing element according to the invention.

According to one aspect of the invention, the second element comprises a nut, which is held by a holder behind an opening of the second element. The frame of the photovoltaic module also has an opening. Through these two openings, the second element and the frame of the photovoltaic module are connected by screwing a bolt with the nut. In this way, a simple and very stable mechanical connection between the stabilizing element according to the invention and the frame of the photovoltaic module is produced, via which the forces acting on the photovoltaic module, to transfer to the frame. It is advantageous, the thread into which the bolt is screwed during assembly, already z. B. by a nut in the element to be mounted and to fix this nut there by a holder in position and orientation and against twisting when screwing the bolt. As a result, during assembly, the bolt must be screwed in only through the two openings without the mother for this purpose to be introduced during assembly in the element and fix it there during screwing. This insertion and fixing during assembly would have to be made by the installer, which depends on the location and location, eg. As an overhead installation, can make very difficult and possibly would require the installation by at least two people. By providing the fixed thread in the element stabilizing element according to the invention, however, can always be very easily and conveniently mounted by a person alone, since only the stabilizing element positioned relative to the frame and the bolt must be screwed.

The idea of the invention relates to a support system which overcomes the disadvantages of existing systems. It is universally adaptable to most common module types and also offers sufficient protection against damage to the modules. The installation is very simple and can be carried out by one person only. In addition, the system offers a very high degree of flexibility and, depending on the area of application, can even be used for the heaviest loads (combined). In order not to drive up the cost factor of the photovoltaic system too much, this support system is available as an option. The installer can order this add-on if needed. The advantage is that there are no additional costs in regions without increased loads. The additional costs for areas with high loads can be explained by the increased service life of the equipment and its resistance to loads.
