Abstract: An arrangement which has a panel-like electrical/electronic module, such as a solar power module, and a connection unit which are electrically connected to one another. The module and the connection unit each have an essentially flat printed conductor structure with connecting sections. The printed conductor structures are situated in parallel planes. The connecting sections are rigid electrical conductor sections and are bent out from the planes of the printed conductor structures of the connection unit and the module. The connecting sections of the connection unit are situated corresponding to the arrangement of the connecting sections of the module so that for the connection unit connected to the module each connecting section of the module is electrically connected to a respective connecting section of the connection unit and these adjoin one another in one section situated in a different spatial position than that of the planes of the printed conductor structures.

Abstract: In a photovoltaic solar module in plate form with an outer plate, an inner plate and a plastic interlayer joining them, in which are embedded solar cells, where the solar cells are interconnected with one another electrically be means of several connecting conductors and where the connecting conductors are each connected so as to be electrically conductive to a connection device arranged in an opening in the inner plate, several connecting conductors are durably connected to a common connection device, which comprises a multiple plug-and-socket connector.

Abstract: A photovoltaic solar module in plate form, in particular for use as a curtain wall or roof element, with at least one outer pane facing towards the incident light, at least one inner cover arranged at a distance behind it in the direction of the incident light, and, if necessary, an edge structure surrounding the outer pane and the inner cover, joining them to one another to form a seal. Solar cells are arranged between the outer pane and the inner cover, embedded in cast resin, laminating film(s) or the like, with a system of conductors interconnecting them electrically, from which connecting leads for electrical connection to other adjacent solar modules lead into the area located outside the plate structure.

Abstract: A plate-shaped solar module, particularly for use as facade element or roof element is provided with an outer pane facing the incident light, at least one inner plate arranged at a distance behind it in the direction of light incidence to create an intermediate space and a peripheral construction running around the outer pane and the inner plate for connecting them in sealing manner. Solar cells are arranged between the outer pane and the inner plate, imbedded in cast resin, compound foil/s or the like, and with a conductor system electrically connecting them. The connecting lines for electric connection with other adjacent solar modules lead into the area of the periphery and the connecting lines are attached on a lug that projects into the intermediate space and is imbedded in the cast resin or the compound foil/s.
