Description

State of the art

[0001] Various mounting systems for photovoltaic modules are known from the state of the art. Typically, individual clamps are used to fix the modules to a support structure at specific points. However, these solutions have several disadvantages: Installation requires a large number of individual fastening elements, which increases installation effort. There is also a risk of water penetrating the area between the modules, especially if the clamps do not seal sufficiently at the connection points.

[0002] Some solutions include continuous mounting rails that provide improved stability. However, these are often not equipped with integrated sealing elements, thus still presenting a risk of water ingress. Furthermore, they lack an efficient and mechanically stable clamping structure that enables a secure connection to the modules without requiring additional components. Problem underlying the invention

[0003] The object of the invention is to provide a mounting rail that ensures both secure mechanical clamping of photovoltaic modules and enables rainproof installation. The design should allow for simple and quick installation and be highly stable and durable. Solution to the problem

[0004] This task is solved by a rail for fastening components, which includes the following features: • An upper roof structure that serves as protection against water penetration. • Two laterally protruding support structures with a raised or protrusion at their outer ends directed into the interior of the rail. These structures enable mechanically stable fixation of the photovoltaic modules. • A mounting groove for receiving a fastening element, in particular a screw connection.

[0005] The roof structure acts as a barrier against penetrating rainwater and diverts it in a targeted manner. The raised or protrusions within the support structures, directed toward the rail, prevent capillary forces that could otherwise suck water into the space between the modules. The mounting groove allows for secure attachment of the rail to the support structure using standardized fasteners, such as M8 hexagon bolts. Advantages of the invention

[0006] The rail according to the invention offers the following advantages over the prior art: • Stability: The continuous rail construction enables even force application to the photovoltaic modules, thereby reducing localized mechanical loads. • Quick installation: The rail replaces several individual clamps, reducing assembly effort and shortening installation time. • Rainproof installation: The special roof structure and the capillary-breaking elevations effectively prevent water from penetrating the spaces between the modules, which is particularly interesting for in-roof systems. • Universal applicability: The rail can be used with standardized screw connections and common photovoltaic modules without the need for additional sealing elements.

[0007] Due to these features, the rail according to the invention represents an optimized solution for the installation of photovoltaic modules, which meets both mechanical and weather-related requirements.
