Problems solved by technology

[0003] If a lot of water gets into the module through a damaged seal so that both the positive and negative conductors are connected to each other by the water, a short circuit is created which can, for example, cause a fire, including damage to the diodes in the terminal box of the module

Embodiment Construction

[0026] exist Figure 1-4 A photovoltaic module 101 known from the prior art (hereinafter also simply referred to as module 101 ) is depicted in FIG. 2 , which comprises a surrounding frame 2 and a composite 10 embedded in the frame 2 . As is known, the composite 10 has photovoltaic cells arranged in a plane, an EVA film is arranged on these photovoltaic cells, and a glass plate is arranged on this EVA film. A Tedlar film can be provided on the underside of the cell. In these figures, only the composite body 10 is shown as a whole, ie its elements (cells, membranes, glass panes) are not shown in detail.

[0027] The composite body 10 is located on four interconnected support profiles on the edge side, namely the transversely extending support profiles 3a, 3b of the frame 2 and the longitudinally extending support profiles 4a, 4b (see figure 1 ). The transversely extending support profiles 3a are defined here as support profiles which form the horizontal lower edge of the mod...

Abstract

The invention relates to a photovoltaic module (1) having a frame (2) made of profiled struts (3a, 3b, 4a, 4b) and a composite (10) which is fastened to the frame (2) and comprises a plurality of photovoltaic cells and at least one transparent layer, preferably an EVA layer, applied to the photovoltaic cells and / or a transparent glass panel. The photovoltaic module (1) according to the invention is characterized in that a spacer device (20) fastened to the frame (2) is spaced apart from the upper face (11) of the composite (10) and also spaced apart from the end face (15) of the composite (10), such that between the spacer device (10) on the one hand and the upper face (11) and the end face (15) of the composite (10) on the other hand a continuous path (28) is provided, by means of which water, in particular rainwater, can run off. The invention further relates to a method for processing a known photovoltaic module.

Description

technical field [0001] Photovoltaic modules usually consist of photovoltaic cells on which an EVA layer (ethylene-vinyl acetate copolymer) and finally a glass plate is placed. A so-called Tedlar membrane is usually arranged on the underside, which has at least one polyvinyl fluoride layer (PVF) (so-called backing membrane), which protects the membrane from the underside against environmental influences. In addition to high UV resistance, the Tedlar film also acts as a moisture barrier. The composite of battery, EVA layer, glass plate and Tedlar film is housed at the edges by a surrounding aluminum frame, which mostly consists of four supporting profiles, where the composite (battery / EVA / glass Plate / Tedlar) and the frame are provided with a U-shaped seal in cross section. Background technique [0002] Undesirable delaminations frequently occur in known photovoltaic modules, in which the aforementioned composite of cell, EVA, glass and Tedlar film is loosened. The reasons f...
