Abstract: A channel nut includes a web, a first flange projecting from the web where the first flange has a first notch for receiving a first lip of a strut channel, and a second flange projecting from the web where the second flange has a first notch for receiving the first lip of the strut channel. The first notch of the first flange and the first notch of the second flange are arranged in a non-aligned relationship with respect to each other such that the first notch of the first flange and the first notch of the second flange form a curved first seat for the first lip of the strut channel.

Abstract: An electrical conductor arrangement, particularly as a component of a photovoltaic array. Such an arrangement is designed having a first electrically conductive element, a second electrically conductive element, and an electrically conductive rod which itself has a threading, wherein the two elements are in electrical contact with each other via said rod.

Abstract: A fastening device for fastening at least one solar panel to an assembly rail which has a slot bordered by two parallel webs is disclosed. The fastening device includes a locking element with two locking hooks which can be inserted under elastic deformation of at least a part of the locking element into the slot, and which, when the locking element is relaxed, can then reach behind the webs of the assembly rail. The fastening device further includes at least one hold-down element for a solar panel which is connected with the locking element. At least one interlocking element is provided which can be inserted into an interlocked position between the two locking hooks, where the interlocking element prevents the two locking hooks from coming closer to each other.

Abstract: A connecting device for a frame structure made of support profiles and crossbars for the arrangement of solar panels, as well as a frame structure with a connecting device, is disclosed. The connecting device has a base element, a receptacle element, and a locking device by which the receptacle element can be fixed relative to the base element on the base element. The base element has a fastening section as well as a support section with a support side facing the receptacle element. The receptacle element has a receptacle for a crossbar of the frame structure as well as an application section with an application side facing the base element. The locking device has a clamping device as well as a bearing device. An application area and at least one depression area are provided between the clamping device and the bearing device.

Abstract: A self-supporting solar array includes a plurality of solar modules and a substructure that supports the solar modules and connects them to each other. The substructure defines a plurality of module positions at each of which a solar module is arranged. Module positions configured as S-module positions are provided in the substructure, and they each have a wind deflector that covers up a passage opening leading to the bottom of the solar module arranged in each S-module position. Aside from the S-module positions, the substructure also has module positions configured as F-module positions in which at least part of the passage opening is free, whereas it is covered by the wind deflector in the case of an S-module position.
