Abstract: A fastening system for connecting two components to each other, which is particularly suitable for attaching mirror elements of a solar collector module to a support frame, and which enables in particular simple handling during assembly of the components, includes a base provided with an upwardly projecting locking pin and intended for mounting on one of the components, and a cylindrical casing forming a receiving channel for the locking pin and intended for mounting on the other component. When the locking pin is inserted in the receiving channel, the cylindrical casing forms in conjunction with the base plate a receptacle for liquid adhesive.

Abstract: Producing a solar trough collector includes fastening a mirror to a structure so that the mirror connects to the structure and has a holding container and a mirrored side facing away from the holding container, the mirror and structure forming joining components, aligning the mirror and structure into a joining position to form a joining gap between joining surfaces; at least temporarily fixing the joining components in the joining position by laying the mirrored side downward in a first holding device, suspending the structure in a second holding device arranged above the mirror, and moving holding devices into the joining position; filling the joining gaps with a joining medium; and allowing the joining medium to harden in the gap to form a permanent connection, wherein the holding devices are held in position until the joining medium has at least partially hardened.

Abstract: The invention relates to an assembly method for the permanent mechanical connection of two components to be assembled, said method being simplified and improved in relation to the compensation possibility of the dimensional variations of the components to be assembled. To this end, the assembly method comprises the following steps: a) a first and a second assembly component (1, 4) are aligned in a precise manner, in an assembly position, forming an assembly gap (7) between the assembly surfaces (3, 3a; 6, 6a) of the components (1, 4) to be assembled; b) the components (1, 4) to be assembled are at least temporarily fixed in this assembly position; the assembly gap (7) is filled with a fluid assembly medium (8), and d) the assembly medium (8) is hardened in the assembly gap (7) to form a permanent connection generating cohesion and adhesion forces, transmitting said forces between the components (1, 4) to be assembled.

Abstract: The invention relates to a method for controlling the orientation of a sun collector (K1, K2, K3, K4), with a heat collecting element (10) respectively arranged in the focal line. The temperature and/or the heat quantity of the heat transfer medium flowing through the heat collecting element (10) are measured in the region of a sun collector (K1, K2, K3, K4) in such a way that they can be associated with same, and the determined temperature values (T1, T2, T3, T4; T?1, T?2, T?3; T?4, T?5) and/or heat quantity values are supplied to a control unit controlling the orientation of each sun collector (K1, K2, K3, K4) and orienting the respective sun collector (K1, K2, K3, K4) according to a determined orientation parameter.

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.
