## Abstract

A stop element for at least one solar module holder, which can be fastened to a substructure by means of fastening means. The stop element comprises: two opposite stop portions and at least one connecting element that connects the two opposite stop portions. One of the two stop portions is coupled to the at least one solar module holder, and the other of the two stop portions is coupled to the fastening means or to a further solar module holder in order to generate a torque on the solar module holder caused by a load.

## Claims

### Claim 1

A stop element for at least one solar module holder which can be fastened to a substructure by a fastening device, comprising:
two opposing stop portions;
at least one connecting element that connects the two opposite stop portions, wherein one of the two stop portions can be coupled to the at least one solar module holder and the other of the two stop portions can be coupled to the fastening device or to a further solar module holder in order to avoid a load caused by a load torque on the solar module holder.

### Claim 2 (depends on 1)

The stop element according to claim 1, wherein the stop element is formed monolithically and can be placed on the substructure.

### Claim 3 (depends on 1)

The stop element according to claim 1, with the two opposite stop portions being formed as V-shaped portions which provide a stop for absorbing the torque, wherein the at least one connecting element couples at end points of the V-shaped portions and, after being placed on the substructure, runs laterally along the substructure.

### Claim 4 (depends on 1)

The stop element according to claim 1, wherein at least one slot is formed on the two opposite stop portions, into which at least part of the solar module holder (40) can be pushed.

### Claim 5 (depends on 4)

The stop element according to claim 4, wherein two stop portions each have a slot in order to allow the stop element to be displaced along adjacent solar module holders while the slots offer a form-fitting hold.

### Claim 6 (depends on 1)

The stop element according to claim 1, wherein the two opposite stop portions and/or the connecting element are formed from a metal in order to make an electrical potential equalization between the substructure and the solar module holder possible.

### Claim 7 (depends on 1)

The stop element according to claim 1, which is formed as a rectangular contour around a rectangular opening which is bent at least once along a line parallel to one of the rectangular edges.

### Claim 8

A solar module installation with:
at least one solar module;
at least one solar module holder which holds the at least one solar module;
a substructure on which the at least one solar module holder is fastened together with the respective solar module; and
at least one stop element according with:
two opposing stop portions;
at least one connecting element that connects the two opposite stop portions,
wherein one of the two stop portions can be coupled to the at least one solar module holder and the other of the two stop portions can be coupled to the fastening device or to a further solar module holder in order to avoid a load caused by a load torque on the solar module holder.

### Claim 9 (depends on 8)

The solar module installation according to claim 8, wherein the at least one stop element which is displaceably arranged along adjacent solar module holders, and
wherein the at least one stop element has at least one slot that is formed on the two opposite stop portions, into which at least part of the solar module holder can be pushed.
