  According to the embodiment, when installing a plurality of solar cell modules 7 on the existing roof 1 on which the roofing material 5 is spread, the solar cell modules 7 are sequentially constructed from the building side toward the eaves side, As shown in FIG. 2, a plurality of solar cell modules 7 are arranged on the roof material 5 by sandwiching the eaves side end portion of the roof material 5 between the fixing bracket 23 and the sandwiching body 35 of the solar cell module 7. A fixing tool 48 such as a nail is driven from above the fixing member 39 attached on the fixing bracket 23, and the fixing member 39, the fixing bracket 3, the sandwiching body 35, and the two roofing materials 5 are placed by the fixing tool 48. What is necessary is just to fix to 2 side.

At this time, the ridge-side solar cell module 7a and the eaves-side solar cell module 7b that are adjacent to each other in the roof flow direction are arranged at an interval A in the roof flow direction, and the ridge-side solar cell module 7a is installed. The position and the installation position of the eaves side solar cell module 7b are shifted in the roof flow direction by an integral multiple of the working dimension D of the roof material 5 in the roof flow direction (for example, three times the working dimension D).
And the draining board 55 fixed to the lower surface of the obstruction | occlusion cover 51 is fastened to the attachment parts 42 and 43 of the fixing member 39 with fasteners 62, such as a rivet, and the solar cell module 7a on the ridge side and the solar cell on the eaves side The module 7b is covered with a closing cover 51. At this time, even when there is a dimensional error or the like in the distance A between the solar cell module 7a on the ridge side and the solar cell module 7b on the eaves side, the draining plate 55 is fixed to the fixing member 39 with the fastener 62 such as a rivet. By moving and adjusting the closing cover 51 to the draining plate 55 in the roof flow direction with respect to the fixing member 39 to the fixing bracket 23, the gap A can be reliably closed. Therefore, the space between the solar cell module 7a on the ridge side and the solar cell module 7b on the eaves side is closed with the closing cover 51, so that the appearance can be improved. Moreover, the construction cover of the solar cell module 7 can be absorbed by the closing cover 51, and the installation position of the solar cell module 7a on the ridge side and the installation position of the solar cell module 7b on the eave side are Since the roof material 5 is shifted in the roof flow direction by an integral multiple of the working dimension D in the roof flow direction (for example, three times the working dimension D), a plurality of solar cell modules 7 corresponding to the roof flow direction are arranged in the roof material 5. The flow pitch can be accommodated, and the appearance of the roof 1 can be improved from this point as well.

  Moreover, even if the vertical dimension of the solar cell module 7 is different from the length (working dimension D) of the roof material 5 in the roof flow direction, the solar cell module 7a on the ridge side and the solar cell module 7b on the eave side Then, the position where the fixing tool 48 such as a nail for fixing the solar cell module 7 to the roof 1 is struck against each roofing material 5 is constant in the roof flow direction. About the obtained solar cell module 7, the fixing tools 45, such as a nail, can be hit | damaged to suitable positions, such as the center part of the roofing material 5, and the several solar cell module 7 can be favorably installed on the roof 1. FIG.

Further, since the snow stopper 65 is attached on the closing cover 51, the snow stopper 65 can minimize the influence of the shadow that blocks the solar rays on the solar cell 10, and the snow stopper 65 can be reduced. There is no risk of impairing the power generation efficiency of the solar cell module 7 due to the provision of.
Further, a draining plate 55 is provided below the closing cover 51, and the eaves side of the draining plate 55 is disposed on the ridge side end of the solar cell module 7 on the eaves side. Water such as rainwater that has entered the lower part of the closing cover 51 from the mounting hole of the bolt for attaching to the closing cover 51 is received by the draining plate 55 and can be smoothly drained onto the solar cell module 7 on the eaves side. The draining plate 55 has a central storage recess 56 recessed downward, a pair of fixed protrusions 57 protruding upward, and a pair of attachment wings 58 recessed outwardly, and in the direction of the row. In order to prevent the rainwater or the like that has entered under the closing cover 51 from flowing in the direction of roof flow in the storage recess 56 or the like so as not to spread significantly in the direction of the girder, I can guide you. Further, by providing unevenness on the draining plate 55, it is possible to give strength to the load from the snow stopper 65. In addition, since the fixing member 39 is integrally attached to the fixing bracket 23 of the solar cell module 7, it is possible to ensure attachment accuracy by integration, and to the fixing member 39, the fixing portions 40 and 41 and the attachment portions 42 and 43. By providing the unevenness due to, sufficient strength against the load from the draining plate 55 can be provided.

  8 and 9 show another embodiment, and the closing cover 51 includes a ridge side cover body 77 and an eaves side cover body 78, and the ridge side cover body 77 and the eaves side cover body 78 are bolt nuts or the like. These fasteners 79 are connected so that they can be expanded and contracted in the roof flow direction. That is, the ridge side cover body 77 and the eaves side cover body 78 are provided with mounting holes 80 and 81 through which the fasteners 79 are inserted, and the mounting hole 80 of the ridge side cover body 77 or the mounting hole of the eaves side cover body 78 is provided. One of 81 is comprised by the long hole of the roof flow direction, and it has comprised the obstruction | occlusion cover 51 so that expansion-contraction adjustment is possible in the roof flow direction in the range of this long hole. The other points are the same as those in the above embodiment.

Therefore, even if a considerable dimensional error or the like occurs in the distance A between the solar cell module 7a on the ridge side and the solar cell module 7b on the eaves side, the closing cover 51 to the draining plate 55 are fixed to the fixing member 39 with the fasteners 62 such as rivets. When the cover cover 51 is fixed, the gap A of the gap A can be reliably and satisfactorily closed by adjusting the expansion and contraction of the closing cover 51 in the roof flow direction.
FIG. 10 shows another embodiment, in which the snow stopper 65 attached on the closing cover 51 is omitted, and the formation of an attachment hole for inserting a fastener such as a bolt into the closing cover 51 and the attachment of the nut 61 are shown.
