Description

  The present invention relates to a connection technique between mounting members when connecting a plurality of solar cell modules to a roof body with mounting members, and a wiring technique for lead wires of the solar cell modules.

  In recent years, as a countermeasure against global warming, technology development for attaching a solar cell module to a roof has been carried out. As a general method, a plurality of stands are partially attached to the roof plate, and attachment members are provided on the left and right ends of the solar cell module to be installed at a predetermined height on the roof body, and the attachment members are fixed to the stand. There is a method in which a plurality of solar cell modules are continuously provided along the inclination direction of the roof body. Lead wires extending from the output terminals on the lower surface of the solar cell module are wired along the lower surface of the solar cell module, the roof plate, or the mounting member.

  By the way, in the said technique, since the attachment member is independent for every solar cell module, it was difficult to connect the front and back attachment members correctly linearly, and when the installation position shifted | deviated, it might look bad. . In addition, since the solar cell modules that are connected are installed separately, when the strong wind flows under the solar cell module, the solar cell module may try to rise, and the installation strength is not satisfactory. There wasn't. On the other hand, since the lead wire is exposed to the outside, there is a problem that it is inferior in durability due to being hit by strong wind, and it is necessary to tighten the lead wire partially with a cable tie etc. It was necessary.
