Next, the roof structure 2 of a house constituted by the solar cell panel 1 having the above-described structure will be described. Here, for the sake of explanation, the upper frame 5 will be referred to as the ridge-side frame, and the lower frame 6 will be referred to as the eave-side frame. Also, the ridge side here is synonymous with the upper side in the installed state, and the eave side is synonymous with the lower side in the installed state. As shown in FIGS. 7, 8, 9 and 10, the roof structure 2 is configured by arranging a plurality of solar cell panels 1 on a roof base plate 27 in a row from the eaves side to the ridge side. The base plate 27 has a downward slope from the ridge side to the eaves side, on which the eaves-side edge of the ridge-side solar panel 1 is ridge-side frame 5 of the eaves-side solar panel 1. Are sequentially arranged so as to overlap with each other, and are fixed on the base plate 27 by screws.

If there is a boundary between the roof structure 2 formed by the solar cell panel 1 and the general roof structure 2A, FIG.
As shown in FIG. 8, a gutter member 28 is provided in the vertical direction at the boundary portion, a roof material 29 on the general roof structure 2A side is overlapped with the gutter member 28, and a third gutter structure 16 is provided on the gutter member 28 side. The solar cell panel 1 is arranged so that the frame 8 faces.
Of the roof structure 2 is constituted. The lower gutter 11 of the vertical frame 7 of the solar panel 1 on the ridge side is connected to the solar panel 1 on the eave side.
And the inner gutter 9
Is installed on the ridge side frame 5 of the solar cell panel 1 on the eave side (see FIGS. 9 and 10). Such an array is arranged in a plurality of rows in the wife direction to form a roof structure 2 of the solar cell panel 1. The solar panel 1 on the wife side engages with the vertical frame 8 having the third gutter structure 16 adjacent to the vertical frame 7 having the inner gutter 9 and the lower gutter 11 as the engaging portion 1.
2 are joined by butt engagement. The joint portion and the third gutter structure 16 are received by a portion that extends outside the lower gutter 11.

The electrical connection between the solar panels 1 adjacent to each other in the wife direction is made by connecting the male connector 34 of the lead 32 to the lead 31 of the adjacent solar panel 1 in the wiring fixing portion 35 opened to the outside. The female connector 33 of the lead wire 31 is connected to the female connector 33, and the male connector 34 of the lead wire 32 of another adjacent solar cell panel 1 is connected to the female connector 33.
(See FIG. 10). At this time, as shown in FIG. 9, one connector connection part of the lead wires 31 and 32 is arranged for each of the wiring fixing parts 35 of each solar cell panel 1. By adopting this wiring configuration, the two lead wires 31 and 32 do not come into contact with each other, and only one connector connection portion is provided. Therefore, the portion may be burned by the heat generated by the connector connection portion or the like. However, this can be prevented for the spread of fire.

In the roof structure 2 of the solar cell panel 1 having such a structure, rainwater that has entered the inner gutter 9 of the solar cell panel 1 on the ridge side flows down the inner gutter 9 and the lower surface of the bottom at the lower end is cut off. From the water holes 10 formed in the eaves-side portion to the surface of the solar cell panel 1 on the eaves side, successively down the surface of the solar cell panel 1 and drained at the eaves-side end (first rainwater flow path) ). The rainwater that has entered the lower gutter 11 is the lower gutter 1
1 flows down from the lower end thereof to the gutter structure 20 formed in the ridge-side frame 5 of the solar cell panel 1 on the eaves side, and further passes through the water passage holes 23 of the gutter structure 20 to form the solar cell panel 1 on the eaves side. It flows down to the inner gutter 9 of the vertical frame 7 (second rainwater flow path).

A part of the rainwater which has flowed into the horizontal gutter structure 20 passes through the gap between the abutting portions, and the extension 14 of the lower gutter 11 and the third gutter structure 16 in the vertical frames 7 and 8 of the solar cell panel 1 on the eaves side. And flows down (third rainwater channel). The rainwater diverted to the lower gutter 11 of the solar cell panel 1 on the eave side is further divided and flows down sequentially in the horizontal gutter structure 20 of the solar cell panel 1 on the eave side as described above. Also, the rainwater diverted to the inner gutter 9 of the solar cell panel 1 on the eaves side flows down to the surface of the solar cell panel 1 on the eaves side, and sequentially passes through the first rainwater flow path described above. It drains down the surface and is drained at the eaves end.

The rainwater that has entered the third gutter structure 16 of the vertical frame 8 flows down the vertical frames 8 connected by the water holes 17 and is drained at the eave tip (fourth rainwater channel). The gutter structure 20 of the ridge-side frame 5 receives rainwater that enters from a joint portion of the ridge-side frames 5 of the solar cell panels 1 adjacent to each other in the wife direction, and the water passage holes 2 formed in the web portion 22.
3 is a structure for splitting and flowing down to the inner gutter 9 which is a vertical gutter and the third gutter structure 16.

As described above, the roof structure 2 of the solar cell panel 1 has the gutter structure as a drainage structure of three rows in the vertical direction and one row in the horizontal direction. Since the rainwater flow path is configured, the roof structure 2 can be constructed without a drainage structure being specially constructed on the base plate 27, thereby reducing the labor and cost of construction. In addition, since the structure drains water from the lower gutter 11 to the inner gutter 9 and the surface of the base 3 as compared with a roof structure in which drain is drained by a single row of gutter members in each row, the capacity of the gutter can be set smaller and the flat area of the roof can be reduced. It can be used more effectively. Furthermore, since the rainwater flow path that diverges sequentially toward the eaves is formed by the water passage holes 23 of the gutter structure 20, the treated rainwater does not increase in volume toward the eaves, and the rainwater flows smoothly. Wastewater treatment is possible.

Further, a cable retainer 36 is provided as holding means for holding the lead wires 31 and 32 floating from the structural surface. The cable retainer 36 is made of flame-retardant plastic, and has a structure in which a mounting structure 38 with legs is integrally formed with a holding portion 37 that holds the lead wires 31 and 32. By fitting the mounting structure 38 into the mounting hole opened in the web portion 22, a plurality of the mounting portions are mounted in the middle of the web portion 22, and the lead wires 31 and 32 are floated from the web portion 22 and the flange 19 and held. As shown in FIG. 11, the attachment position of the cable retainer 36 is convenient because the connector connection portion does not loosen due to its own weight and can stably hold the leads 31 and 32, as shown in FIG. By adopting such a configuration, it is possible to prevent fire from spreading from the electric system to other members, and it is possible to further enhance the safety of the solar cell panel 1 and the roof structure 2 therewith.
