Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an output output structure for a solar cell module. More specifically, the present invention relates to a solar cell module output take-out structure using a waterproof and moisture-permeable membrane and having improved mounting workability and reliability.

[0002]

2. Description of the Related Art The output terminals of a solar cell module include a screw-in type, a lead type, a socket type, etc. In each case, an electrical connection between the solar cell element and an output lead wire is provided for insulation. A terminal box having a waterproof structure provided inside is often provided. Particularly recently, a building material-integrated solar cell module in which a solar cell element is integrated with a building material has been attracting attention, and it is necessary to provide compatibility with ordinary building materials, and to increase the thickness of the building material-integrated solar cell module from an aesthetic point of view. It is desired to make it thinner. Accordingly, it is necessary to make the terminal box attached to the back surface smaller. JP-A-7-
No. 273361 discloses that a terminal box having a waterproof property is manufactured by filling the inside of the terminal box with a filler, and curing the terminal box in order to reduce the size of the terminal box and obtain a necessary waterproof property. It is described.

[0003]

In the terminal box as described above, if the solar cell module is transported in a state where the filler is uncured, the electrical connection inside the box member is exposed. In the worst case, there is a problem that the filler overflows outside the box member. Therefore, there is a problem that it takes a time for the solar cell module to stand still and harden until the filler does not flow, and it takes much time to manufacture the solar cell module by the hardening time of the filler. Further, it is conceivable to cover the box member in a state where the filler is uncured in order to shorten the manufacturing time of the solar cell module. However, in particular, in the case of a terminal taking-out structure of a thin solar cell module, a sufficient distance cannot be maintained between the liquid level of the filler and the top plate of the lid, and the filler is almost completely filled with the box, In addition, since a low-viscosity filler is used so that the filler wraps around the inside of the box member, the filler is extruded by air pressure when arranging the lid, and flows out of the box or comes into contact with the lid. By curing in the state that
Insufficient filling and associated insulation failure may occur. Also, even if the lid is carefully covered so that the filler is not extruded, it is necessary to carefully transport the solar cell module so that it does not tilt when flowing the solar cell module to the next process such as inspection and packing. However, in the measurement such as the output measurement in which the light receiving surface of the solar cell module is directed upward, the filler flows out, so that there is also a problem that the measurement cannot be performed until the filler is hardened to the extent that the filler does not flow out. .

[0004]
