As shown in FIG. 8, the roofing material type array 1 according to the second embodiment of the present invention includes a second outer wall portion 13b in the Y direction in the second outer wall portion 13b of the second frame 13 of the first solar cell module 3A. The first hole 13f that penetrates through the first hole 13f. Further, the first outer wall portion 12b of the first frame 12 of the second solar cell module 3B has a second hole portion 12g penetrating the first outer wall portion 12b in the Y direction. Further, the + Y side tip of the first flange portion 13 e of the second frame 13 covers the first frame 12 from below and reaches the + Y side of the first frame 12. The length of the second receiving portion 13i of the second frame 13 in the X direction is shorter than the length of the third outer wall portion 14b between the opposed third frames 14, and the second receiving portion when the solar cell module 3 is installed. The end of 13i in the X direction has such a length that it is above the flange member 4.

  According to the present embodiment, the first hole portion 13f of the second frame 13 and the second hole portion 12g of the first frame 12 are near the corner portion formed by the solar cell panel 11 and the first frame 12, and the solar cell. Since the solar cell module 3 is cooled by reducing the stagnation of air in the vicinity of the corner formed by the panel 11 and the second frame 13, the solar cell module 3 has a function of increasing the power generation efficiency.

  In addition, rainwater that has entered from the second hole 12g of the first frame 12 is received by the first flange portion 13e of the second frame 13 so as to suppress water immersion to the back side, and the rainwater wets the inclined surface 2 and causes corrosion. It can suppress the cause. Similarly, the rainwater that has entered from the first hole 13f of the second frame 13 can be received by the second receiving portion 13i, and the infiltration to the back side can be suppressed.

  Further, the length of the second receiving portion 13i of the second frame 13 in the X direction is shorter than the length of the third outer wall portion 14b between the opposing third frames 14, and the second length when the solar cell module 3 is installed is second. The length of the end portion in the X direction of the receiving portion 13 i is located on the flange member 4. Thereby, the water received by the 2nd receiving part 13i can be drained on the gutter member 4, and it can drain without making the inclined surface 2 wet.

<Third Embodiment>
The roofing material type | mold array 1 which concerns on 3rd Embodiment of this invention has the short eaves member 4 arrange | positioned at the 1st solar cell module 3A and the 2nd solar cell module 3B, as shown in FIG.

  Thereby, the eaves member 4 drains rainwater between the first solar cell module 3A and the second solar cell module 3B by connecting between the second flange portion 14e and the third receiving portion 14g of the third frame 14. Can do.

  In this embodiment, the raw material of the gutter member 4 can be reduced, and the workability of the operator can be improved by downsizing the member handled on the inclined surface 2.

  Note that the solar cell module 3 applicable to the present embodiment is not limited to the super straight structure solar cell module described in the above embodiment, and has various structures such as a glass package structure or a substrate structure. It is applicable also to a solar cell module.
