Abstract

The invention is directed to a solar module (1) having an electrical connecting system (3) which allows considerable flexibility with regard to the arrangement and interconnection of a plurality of solar modules (1) to form a solar module arrangement, for example on a flat surface.

The electrical connecting system (3) comprises at least one connector element (4) for external electrical connection of the solar module (1), wherein the connector element (4, 7, 8, 9) is connected with the layer arrangement (2) in a peripheral area (26) thereof via at least one contact element (5) projecting into the layer arrangement (2). The connector element (4, 7, 8, 9) comprises at least one mechanical connecting means, by means of which the connector element (4, 7, 8, 9) may be connected with a separately formed, further connector element (4, 7, 8, 9), which is in turn connected with the layer arrangement in the peripheral area via at least one contact element projecting into the layer arrangement (2).

Claims
