Description

The invention relates to a mounting system, in particular for mounting photovoltaic modules, wherein the mounting system has at least one frame for enclosing a PV module, wherein the frame comprises a plurality of side strips and preferably at least four side strips. The invention further relates to a use of a mounting system and a method for installing a mounting system.Such a mounting system for photovoltaic (PV) modules is already known from CN 209881696 U. An approximately W-shaped profile has a small, T-shaped tip in the middle on its top and in cross section. A clamp of approximately U-shaped cross-section is latched onto this nose, for which purpose the clamp comprises inwardly projecting latching wings on its U-legs. In addition, the clamp has clamping wings angled outwards on its U-legs, which apply a clamping force to an edge of a PV module from above. As a result, the PV module is pressed onto a lower side of the W-shaped profile, which is formed by a W-leg.The frames of the individual PV modules are substantially formed by two W-shaped profiles which extend along a plurality of PV modules and are quite long. The PV modules arranged one after the other between the two W-shaped profiles each have a gap between them, into which a transverse strut or side strip made of plastic is snapped as spacer between two PV modules. For this purpose, the cross strut / side strip has a plurality of barbs in cross section. Below the spacer cross strut there is a U-shaped cross section which connects the two W-shaped longitudinal sections to one another and stabilizes the mounting system.The disadvantage of the known mounting system is that it can be mounted quickly and largely without tools with respect to large surfaces. However, this system is quite inflexible because the W-shaped longitudinal profiles must be cut to size and, in addition, are difficult to transport. The object of the invention is therefore to further reduce the effort and in particular the transport and assembly effort and / or to increase the assembly flexibility.This object is achieved by a mounting system, in particular for mounting photovoltaic modules, wherein the mounting system has at least one frame for enclosing a PV module, wherein the frame comprises a plurality and preferably at least four side strips, wherein the mounting system or the frame has at least one and preferably at least four connectors, wherein the at least one connector is designed for connecting at least two of the side strips, wherein the connector and the side strips are designed such that the connector is connected or can be connected in a plugged manner to at least one side strip - and preferably to at least two side strips - of the plurality of side strips of the frame.The invention is initially based on the finding that long side strips can clearly accelerate the assembly, although this is accompanied by a slight flexibility. Finally, v.a. benefit. PV systems on large, monotone surfaces of mounting systems with long side bars. Large, monotone surfaces are very often not present, however, so that mounting systems with long side bars often cannot perform their mounting advantage.It has been found that the side strips are to be adapted to the length of the module sides, whereby the side strips are significantly shorter and easier to transport compared to the W-shaped profiles from CN 209881696 U. The plug-in connectors according to the invention enable a very comfortable, tool-free and thus quick connection of the side strips, as a result of which the mounting system according to the invention can be installed not only very flexibly but also very quickly.The invention is based in particular on the finding that a somewhat higher outlay in the production of the side strips with exactly configured length and corresponding connectors is overcompensated by the lower outlay during transport and assembly. As a result, a flexible, modular quick-fitting system is provided and the object mentioned at the beginning is achieved.The term "top side" or the word "top side" and words having the same word stem preferably relate to the orientation of the installed mounting system. In particular, these terms mean those sides or surfaces of the mounting system or of the components of the mounting system which face the sun. Expediently, the upper sides of components of the mounting system are parallel or substantially parallel to an active surface of a PV module and further preferably face in the same direction. Terms such as "bottom side" or "lower" are preferably to be understood analogously to "top" and the like. For example, in the case of a standing frame, the upper side of a component is not recognizable in a plan view, but in a side view.The term "axial" preferably means a direction of a longitudinal extent of a side strip. The term "longitudinal extent" expediently means that dimension of a body in which the body or the side strip has the greatest extent. Conveniently, the term "axial" refers to a longitudinal axis of a body. The longitudinal axis of a body or of a side strip preferably runs through a surface center point of a cross-sectional surface spanned by the body in cross section. Axial directions with respect to a side strip are expediently directions parallel to the longitudinal axis of the side strip. The term "transverse direction" preferably means a direction perpendicular to the height direction and perpendicular to the longitudinal direction of the side rail.It is very advantageous that the connector is connected or can be connected in a plugged manner to the at least one side strip or to at least one end side of the at least one side strip-in the axial direction of the at least one side strip.

It is very preferred that the end faces of the at least two side strips are open. It is very advantageous that the side strips or the end sides of the at least two side strips can engage or engage a positive fit and / or a frictional fit with the connector in the direction and / or in the transverse direction.

The stop can be formed in particular by an angle of the connector.Particularly preferably, the connector is insertable or plugged into the at least one side strip or into an end face of the at least one side strip. Particularly preferably, the connector is insertable or inserted into the at least two side strips or into end faces of the at least two side strips.

At the same time, the hollow profile can have a continuously constant cross section (apart from complementary latching elements and latching parts), so that the production process of the hollow profiles can be designed correspondingly efficiently. Preferably, the connector comprises at least a first leg and a second leg. Advantageously, the first leg can be connected or plugged to a first of the at least two side strips-in particular axially-and is preferably plugged or insertable.

In addition, the hollow profiles are particularly advantageously suitable as plug elements and in particular as plug-on elements.
