This has the disadvantage that, on the one hand, the holes are produced in the region of the glass pane or plate which is spaced apart from the solar cells in order not to damage the solar cells, so that the region is not used. to generate current
The carrier has a relatively high temperature, especially in the case of very strong sunlight, which makes it difficult to integrate the electronics or the inverter into the junction box due to possible overheating, or to shorten the inverter. Transformer service life

Embodiment Construction
[0025] figure 1 The solar module 1 according to the invention is shown in a first state of manufacture. The solar cells 2 are arranged on the front side of the carrier 4 and are electrically connected to one another. The solar cells 2 and the carrier 4 are covered by a cover layer 5 . In one embodiment, the cover layer can be formed as an EVA (Ethylen-Vinyl-Acetat, Ethylene Vinyl Acetate) film, which is applied to the solar cells and the carrier, for example, by a vacuum method and completely encloses the solar cells. A further transparent element, for example a glass layer, is arranged on the cover layer 5 . The cover layer 5 itself can also be designed as a glass layer or include it. The electrical connection to the solar cells 2 is established via a main line, which is electrically connected to a plurality of strips 3 in the edge region of the carrier 4 , wherein the strips 3 are arranged between the carrier 4 and the cover layer 5 and protrude beyond the carrier 4 the ...

The invention relates to a solar module (1) having a plurality of solar cells (2) mounted on the front side of a carrier (4) of the solar module (1), wherein a plurality of conductive strips (3) are in electric contact with the solar cells (2) and extend from the front side to the rear side of the carrier (4), and the carrier (4) is enclosed on the periphery by a frame (6) of the solar module (1).The invention also relates to a connection system comprising the solar module (1) and a junction box (8) that can be connected to a module electronic device (12) by a socket (9) of the junction box (8) for forming a solar module system.
Description
technical field [0001] The invention relates to a solar module, a connection system with a solar module and a solar module system. Background technique [0002] Photothermal solar generators with solar modules are gaining increasing significance as decentralized, renewable energy generators and enable a sustainable, resource-friendly energy production. In order to be able to achieve energy generation costs that are competitive with those of fossil energy carriers, in particular solar modules need to be produced cost-effectively, but also the devices for converting the generated direct current power into the supply network for input into the supply network. Power electronics required for AC power. [0003] Leading the electrical connection lines out from the solar cells of the solar module is a particular technical challenge. Usually, for this purpose, a hole or holes are made in a glass plate, film or plate which is used as a cover or carrier for the solar cells, in order ...
