Further, the fastening element 39 is inserted into the fixing hole 436 of the fixing portion 426 of the ridge side frame portion 405 of the solar cell module 402D and the fixing hole 445 of the conductive member 421, and is mounted on the roof tile bar 307.
In the left frame portion 407 of the solar cell module 402C, the closed portion 141 is in contact with or close to the closed portion 146 of the right frame portion 408 of the solar cell module 402D, and the upper portion of the flow path 135 is covered by the closed portion 146. ing.

When the laying of the second-stage solar cell module 402 on the basic roof structure 304 is completed, the roof tile member 300 and the solar cell module 402 of the third and subsequent stages are laid, and the roof structure 1 is completed.

According to the solar cell module 402 of the present embodiment, since the solar cell panel 5 is reinforced by the reinforcing bars 410, it is hard to be damaged.

In the above-described embodiment, the crystalline solar cell panel is adopted as the solar cell panel 5, but the present invention is not limited to this, and the solar cell panel 5 may be another type of solar cell panel. Good. For example, it may be a thin film solar cell panel in which thin film layers are laminated on a glass substrate.

In the above-described embodiment, the cutout portions 58, 59, 64 are formed at both ends and the middle portion in the extending direction of the snow stopper 66 to allow rainwater or the like flowing on the solar cell panel 5 to pass to the eaves side. However, the present invention is not limited to this. For example, as shown in FIG. 60, instead of providing the cutout portion 64 in the split piece 23, the second split pieces 23, 23 having no cutout portions 64 are provided at a predetermined interval with respect to the first split piece 22. Alternatively, the water passage port may be formed by forming the gap 560 in the lateral direction X by attaching the water passage port.
Further, for example, instead of providing the cutout portions 58 and 59 on the split piece 23, the second split piece 23 without the cutout portion 64 is not installed up to both ends of the first split piece 22 in the lateral direction X, and The water passages 561 and 562 where the second divided piece 23 is not provided are formed on the divided piece 22. Then, the water passages 563 may be formed by overlapping the water passages 561 and 562 of the solar cell modules 2 and 2 adjacent to each other in the column direction.

In the above-described embodiment, the snow stopper 66 of the eaves-side frame 16 has the one notch 64 formed at the intermediate portion in the extending direction, but the present invention is not limited to this. As shown in FIG. 61, the snow stopper 66 of the eaves-side frame 16 may have a plurality of notches 64 formed in the middle portion in the extending direction.

In the above-described embodiment, the roof tile member 300 and the solar cell modules 2 and 402 are laid in order from the right side to the left side with respect to the basic roof structure 304, but the present invention is not limited to this, and FIG. As described above, the roof tile member 300 and the solar cell modules 2 and 402 may be laid in order from the left side to the right side of the basic roof structure 304.

In the above-described embodiment, the ridge-side gasket portion 28 provided in the ridge-side frame portions 15 and 405 is integrally formed with the hard gasket portion 45 having a “U”-shaped cross section and the soft gasket portion 46 having an annular cross-sectional shape. However, the present invention is not limited to this. For example, in the ridge-side gasket portion 28, as shown in FIG. 63( a ), a hard gasket portion 45 having a “U”-shaped cross section and a soft gasket portion 46 having a “U”-shaped cross section are integrally formed. Alternatively, as shown in FIG. 63( b ), the two hard gasket portions 45 may be integrally formed with the soft gasket portion 46 having a “B”-shaped cross section.

In the above-described embodiment, the ridge-side gasket portion 28 is provided only on the ridge-side frame portion 15, but the present invention is not limited to this. For example, in the case of a solar cell module in which frame portions are provided on two sides of the solar cell panel 5 that face each other in the vertical direction as shown in FIG. 64, a gasket portion 28 may be provided on each frame portion. Furthermore, for example, in the case of a solar cell module in which frame portions are provided on the four sides of the solar cell panel 5 as shown in FIG. 65, a gasket portion 28 may be provided on each frame portion.

In the above-described embodiment, the ridge-side gasket portion 28 is formed by extrusion molding the two layers of the hard gasket portion 45 and the soft gasket portion 46, but the present invention is not limited to this. The hard gasket portion 45 and the soft gasket portion 46 may be separately formed by extrusion molding, and then the hard gasket portion 45 and the soft gasket portion 46 may be bonded to be integrated.
