Abstract: The invention relates to a tracking device (1) for solar modules (2a) with a series of posts (3) arranged along a longitudinal axis. A crossmember (6) is pivotably mounted on each post (3), and said crossmembers (6) are pivotable about a common pivot axis (S) extending parallel to the longitudinal axis. There is fastened to each crossmember (6) a toothed ring (7) of which the toothing (7a) is in engagement with a motor-driven toothed wheel (8) mounted on the respective post (3). Also provided is a positive guide means which forms a safeguard against a transverse displacement of the toothed wheel (8) relative to the toothed ring (7). Each toothed wheel (8) is mounted on the side of the respective post (3).

Abstract: The invention relates to a method for monitoring the ramming of a ram post (1) into the ground. A succession of blows are struck on the ram post (1) via an impact driving device (3), causing the ram post (1) to be rammed into the ground. Parameters for the load-bearing capacity of the ram post (1) in the ground are ascertained during the ramming of the ram post (1) via a monitoring unit (14).

Abstract: The invention relates to a support structure for solar modules, with an arrangement of posts mounted on a base. A carrier unit is pivotably mounted on each post, the carrier unit having two struts supporting a crossbeam. The ends of the struts facing away from the crossbeam are mounted in a pivot bearing. The crossbeam is mounted on the post by guide means so as to be movable. Receiving means for mounting solar modules are provided on the crossbeam. The inclination of the solar modules is defined by adjusting and fixing a pivot position of the carrier unit.

Abstract: A fastening system including a plurality of fastening modules to mount a solar module having a first longitudinal direction on a roof structure or a façade having a second longitudinal direction. Each fastening module comprises one module carrier mountable on the roof structure or on the façade; a slide block guidable inside the module carrier; a module clamp; and a fastener to connect the module clamp to the slide block to clamp a respective solar module between the module clamp and the slide block. The module clamp is rotatable between two positions on the fastener so that an arrangement of the fastening modules permits the solar module to be mounted on the roof structure or the façade with the first longitudinal axis perpendicular or parallel to the second direction.

Abstract: A support arrangement for a solar module includes a post having a first surface section. A support structure includes a connecting element presenting a second surface section facing the first surface section in a direction of a joint surface normal of the first and second surface sections. A stop element is arranged in the surface normal direction offset to the first and second surface sections. A first form-fitting connection exists between the stop element and the post and a second form-fitting connection exists between the stop element and the connecting element, providing vertical support of the connecting element relative to the post. The first and second form-fitting connections are producible at different heights of the connecting element relative to the post. A fastening element holds in place the first surface section and the second surface section relative to each other in the direction of the joint surface normal.
