Abstract: A compensating element having a first and a second assembly, wherein a locking mechanism is provided which can be switched over between a first and a second operating state. In the first operating state, the first assembly is connected fixedly to the second assembly and, in the second operating state, the first and second assemblies are connected to each other via a spring mechanism in such a manner that they are movable relative to each other. The locking mechanism includes an electric motor that can be used to switch over between the first and the second operating state. A locking ring is or is not braced against at least three balls depending on its rotational position with respect to a center axis. The locking ring is connected in terms of rotary drive to the electric motor via a torsion spring which is elastic with respect to the center axis.

Abstract: The invention relates to a holding system (1) for mounting a photovoltaic module (6) to a base (8) by means of ground supports (2, 2a, 44, 44a) which comprise a bearing head (4, 4a, 50, 50a), a ground support body (22) and a bearing surface (28, 48) on the bottom side which counteracts a penetration of the ground supports into the base (8), wherein the ground supports (2, 2a, 46, 46a) comprise on their head side a bearing plate (14, 14?, 14a, 14a?, 54, 54?, 54a, 54a?) that is disposed at a slanted angle (?) in relation to the base (8), and wherein the ground supports (2, 2a, 46, 46a) are provided and prepared such that, in the mounted state, the bearing plates (14, 14?, 14a, 14a?, 54, 54?, 54a, 54a?) of a ground support pair (2, 2a, 46, 46a) are spaced apart from each other vertically in relation to the base (8) and from each other horizontally in adjustment to the photovoltaic module (6) and that they are aligned with each other at least in essence.
