[0015]

The roofing material with a solar cell according to the present invention having such a structure has a structure in which the backup material is dropped between the trees to store the cords and connectors of the solar cell and the backup material. There is an advantage that an operation such as providing a gap for passing a cord therebetween is not required. In the roofing material with a solar cell according to the present invention, the cord and the connector of the solar cell are provided with a groove portion provided on a back-up material attached to the back surface of the roofing material with a solar cell and a backup for connection. Since it is housed in the groove provided in the material, the construction can be performed more simply.

The width of the connecting backup material is large enough to connect the connectors at the ends of the cords extending from the roofing material for roofing with solar cells located on the left and right. The work for connecting the left and right connectors can be performed after the backup material for the roof and the roofing material for the horizontal roofing with solar cells on the left and right sides thereof are installed on the foundation, and there is also an advantage that the work is easy. After connecting the connector in this way, store the connector and cord in the groove of the backup material for the connection, and cover the surface material for the connection, but it is possible to construct without special skill. There is an advantage that you can.

Further, since the back-up material is attached to the back surface of the front material, the space 8 shown in FIG. 9 does not exist. For this reason, "If the roofing material with solar cells is not formed of a thick plate material, if the roofing material with solar cells on the space is stepped on during work, the roofing material with solar cells will be recessed. The problem is that you can do it. "
Is resolved. Even if you step on the roofing material with solar cells while working, the backing material is attached to the back surface, so it is possible to prevent the roof material with solar cells from being dented. It is.
