A bearing axle for photovoltaic modules includes at least two tubes, which each have a non-circular cross section at least in one end region. The non-circular cross sections of the at least two tubes are designed to correspond to each other such that a non-rotatable connection between at least one first and at least one second of the at least two tubes can be produced by way of inserting the at least one first of the at least two tubes into the at least one second of the at least two tubes. The bearing axle includes at least one separate connection means, which can be arranged intermediately between at least two tubes, and by way of which the particular at least two tubes are connectible non-rotatably to each other by form-lockingly coupling the at least one connection means to their free end regions with non-circular cross sections.

The present invention concerns a holding device (10) to fasten, especially to clamp, a surface module (20), especially a framed solar panel, on at least one support (30), especially a profile rail, with a head section (12; 112) that is suitable to interact with the surface module (20), a foot section (16; 116) that is suitable for interacting with the support (30) and a connecting element (19) that is suitable for linking the head section (12; 112) with the foot section (16; 116), with the head section (12; 112) being shiftable relative to the foot section (16; 116) along a vertical axis (H) of the holding device (10) by means of the connecting element (19), with the head section (12; 112) being positionable relative to the foot section (16; 116) in at least two angle positions that are twisted towards each other around the vertical axis (H) in such a way with a pre-determined twisting angle that the head section may be positioned at least in two of the angle positions each on at least one or at least two surface modules, especially with one or several contact sections that are arranged according to the respective angle positions. This allows an installation of surface modules in a simple and flexible way using only a single type of holding device.

A system to prevent a sliding nut in a channel in a bar from escaping from the channel, and to prevent the nut from entering a no-go-zone at the end of the channel. The system is adjustable to position the nut at a desirable location along the length of the channels to mount coupling devices onto the bar.

A photovoltaic mounting system for tile roofs is disclosed. In one embodiment, mounting bracket is attached to a roof deck and passes through a flashing support and flexible flashing that mimics the contour of the adjacent roof tiles. In other embodiments, a tile hook passes through partial or full tile replacement flashing. A plug or other structure blocks the space around the tile hook preventing the ingress of pests and debris under the flashing and surrounding tiles. Additional photovoltaic module mounting hardware, including sections of rails and frame mounts are attached either the mounting bracket or tile hook.

A support frame is for a photovoltaic power generation system. The support frame includes a frame member including a first portion positioned at one surface of a solar cell panel and a second portion positioned at the other surface of the solar cell panel, wherein the second portion is openably coupled to the first portion.

The present disclosure relates to the field of sensor manufacturing technology, particularly discloses a method for manufacturing a micro-sensor body, comprising the steps of S1: applying a wet colloidal material on a substrate to form a colloidal layer, and covering a layer of one-dimensional nanowire film on the surface of the colloidal layer to form a sensor embryo; S2: drying the colloidal layer of the sensor embryo to an extent that the colloidal layer cracks into a plurality of colloidal islands, a portion of the one-dimensional nanowire film contracting into a contraction diaphragm adhered to the surface of the colloidal islands while the other portion of the one-dimensional nanowire film being stretched into a connection structure connected between the adjacent contraction diaphragms. By the method for manufacturing a micro-sensor body of the present disclosure, the contraction diaphragms and connection structures formed by stretching the one-dimensional nanowire film are connected stably, which enhances the stability of the sensor devices; and the cracking manner renders it easy to obtain a large-scale of sensor bodies with connection structure arrays in stable suspension.

Disclosed herein is a roof attachment assembly for mounting a solar panel on a roof without the use of rails. The assembly includes a flashing member, a pivot bracket member, a clamp member, an array skirt and a splice member. The flashing member anchors the roof attachment assembly to the roof. The pivot bracket member is rotatably connected to the flashing member. The clamp member is connected to the pivot bracket member and is rotatably connected thereto. The clamp member includes grounding elements for electrically grounding the solar panel. The array skirt is removably connected to the clamp member. The splice member includes grounding elements for electrically grounding the solar panel and is removably connected to the array skirt. Also disclosed is a method of using the assembly and an assembly kit.

In an example, the present invention provides a solar tracker apparatus. In an example, the apparatus comprises a center of mass with an adjustable hanger assembly configured with a clam shell clamp assembly on the adjustable hanger assembly and a cylindrical torque tube comprising a plurality of torque tubes configured together in a continuous length from a first end to a second end such that the center of mass is aligned with a center of rotation of the cylindrical torque tubes to reduce a load of a drive motor operably coupled to the cylindrical torque tube. Further details of the present example, among others, can be found throughout the present specification and more particularly below.

A solar panel awning device may include a solar panel having first and second opposing ends, first and second opposing sides extending between the first and second opposing ends, and first and second opposing major surfaces.
