Description

  The present invention relates to the installation of a solar cell module on a roof, and the wiring of a solar cell module can be used for grounding (grounding between modules) that can prevent the cable from hanging down and prevent deterioration. It relates to a cable holding material.

Regarding the installation of the solar cell module on the roof, there has been a lot of work in connecting the wiring cables at the location where there is a gap between the solar cell modules. That is, the wiring cable does not adopt a material configuration suitable for outdoor installation, and deterioration due to ultraviolet rays and wear (deterioration) due to rubbing with the roof occur.
As a process for preventing the above-mentioned problem, a method of protecting the solar battery module from ultraviolet rays through a wiring cable in a tubular member such as a PF tube, a binding cable of a wiring cable so as not to rub against the roof, or A method of fixing with a support (support member) as shown in Patent Document 1 or a method of using both of them has been adopted. In addition, these fixations were fixed to the module frame, the support material for PV installation, etc.

However, the above-described operation using the tubular member such as the PF tube has to be performed in parallel with the connection operation that requires a large amount of labor such as tilting the solar cell module in the process.
In addition, as with the wiring cable, the grounding wire used for grounding between the solar cell modules does not adopt a material configuration suitable for outdoor installation. It has been carried out in parallel with the connection work.
As described above, the work required for the wiring cable connection work is complicated and extremely troublesome. In addition, since the labor of the work is complicated, there is a problem in that an equal work level cannot be obtained by leaving the work to the operator.

  Therefore, the present invention relates to the installation of a solar cell module on a roof, a solar cell module that can suppress the sagging of a wiring cable and prevent deterioration and can be easily used for grounding (grounding between modules). The purpose is to propose a wiring cable holding material.

  The present invention has been proposed in view of the above, and is a wiring cable holding material having a position restricting portion that abuts each end edge of adjacent solar cell modules, and the upper surface of the supporting material in the disposed state. An upper surface portion along the upper surface portion, a storage portion that is located below the upper surface portion and stores the wiring cable of the solar cell module, and a covering portion that covers the storage portion and is wider than the interval between the solar cell modules facing the support material And a wiring cable holding material for a solar cell module.

  Furthermore, the present invention is a wiring cable holding member that is mounted on a support member that supports each edge of adjacent solar cell modules, and abuts each edge of adjacent solar cell modules in the installed state. A position restricting portion to be moved, an upper surface portion along the upper surface of the support material, a storage portion positioned below the upper surface portion for storing the wiring cable of the solar cell module, and covering the storage portion and facing on the support material The present invention also proposes a wiring cable holding member for a solar cell module, which has a covering portion wider than the interval between the solar cell modules.

Since the wiring cable holding material of the present invention can be fixed along the support material, and can cover the wiring cable and be stored in the storage portion, the wiring cable can be prevented from sagging and protected from sunlight (ultraviolet rays). Thus, deterioration can be prevented. Therefore, the PF pipe that has been used to protect the distribution cable, the binding band and the support that have been used to fix the distribution cable, and the member that combines the roles of fixing screws into one member. it can.
In addition, the wiring cable holding material of the present invention can be performed in a separate process from the wiring cable connection work that requires a large amount of labor, such as tilting the solar cell module greatly, and the work itself requires special techniques and tools. Because it can be easily attached to the support material, it can reduce the burden on the installer, reduce work errors such as forgetting to do work, and reduce variations in construction quality due to the skill of the operator.
Furthermore, when adopting a mechanism that can be housed in the housing part simply by lifting the wiring cable from below as in the illustrated embodiment (first embodiment) described later, substantially no troublesome operation is performed. The wiring cable can be protected at an appropriate position very easily.
Further, since the support member has the position restricting portion of the solar cell module, it is only necessary to arrange the solar cell module so that the edge abuts the position restricting portion, and the solar cell module can be easily arranged. it can.

  Further, the wiring cable holding member having the position restricting portion of the solar cell module may be provided with the solar cell module so that the end abuts against the position restricting portion, and the solar cell module can be easily arranged. .
