  The rainwater flowing on the upper surface of the solar panel 2 is guided to the upper surface of the slate 3 by the eave cover 23 and the drainer 140.

The solar power generation roof 100 of the present embodiment will be described.
The photovoltaic roof 100 is constituted by the eaves cover 23, the drainer 140, and the ridge end of the roofing material 3 (see FIG. 2). The solar power generation roof 100 is provided between the solar panel 2 and the roof material 3 on the roof surface 100A.

  Next, the eaves cover 23 shown in FIG. 3 includes an attachment member 231 and an eaves cover portion 232. The eaves cover portion 232 extends a predetermined distance toward the eaves side and then extends downward. The eaves cover 232 is fixed to the gantry 20 via the mounting member 231.

  The drainer 140 includes a first drainer 141 and a second drainer 142. The draining section 140 guides rainwater flowing on the solar panel 2 on the ridge side to the upper surface of the roofing material 3 on the eave side. The first draining member 141 and the second draining member 142 are made of an aluminum material (extruded member).

  The first draining member 141 is disposed at a position where its ridge side end is covered by the eaves cover 23, and is provided on the base material 5 constituting the roof surface between the solar panel 2 and the roofing material 3 with an adhesive or the like. Fixed. A plurality of the first drainers 141 are arranged side by side in the width direction orthogonal to the inclination direction on the roof surface, and adjacent side surfaces are bonded to each other. The first drainer 141 has a role of supporting a second drainer 142 to be described later and fixing the same to the roof surface.

The first drainer 141 has a bottom surface 141A, a first inclined surface 141B, and a mounting surface 141C.
The bottom surface portion 141A extends along the base material 5 and is fixed to the base material 5 with screws. The ridge-side end of the bottom surface portion 141A is disposed on the lower surface of the eave-side end of the waterproof tape 24 disposed on the lower surface of the gantry 20 of the solar panel 2.

The first inclined surface portion 141B is formed to be thick so as to extend upward from the ridge side end of the bottom surface portion 141A toward the eaves side. At the eave-side end of the first inclined surface portion 141B, a concave portion 141D that is concave toward the ridge side is formed. A first engagement piece 142B of a second draining member 142, which will be described later, is engaged with the concave portion 141D. In addition, since this 1st slope part 141B is formed thick, the adhesiveness of the side surface of the adjacent 1st draining member 141 becomes favorable.
The mounting surface portion 141C extends along the lower surface of a second inclined surface portion 142A of a second draining member 142 described later. The mounting surface 141C supports the second inclined surface 142A.

  The second drainer 142 is detachably attached to the attachment surface 141C of the first drainer 141, and is disposed so as to cover the ridge-side end of the roofing material 3. More specifically, in the second draining member 142, a first engagement piece 142B, which will be described later, is engaged with the recess 141D, and a second engagement piece 142C is engaged with the ridge-side end 141E of the mounting surface 141C. In this state, it is detachably screwed to the mounting surface 141C.

The eave cover 23 can be attached before or after the first drainer 141 is attached.

In the construction step S2 shown in FIG. 5, the roof material 3 is attached to the roof surface. Specifically, the ridge-side end of the roofing material 3 is inserted with the water-stopping member 143 disposed in a groove formed between the eave-side end of the first drainer 141 and the mounting surface 141C. . Thereby, the installation range of the roofing material 3 is determined.

That is, the area from the virtual line X to the eaves side end and the area inside the virtual line Y (the area from one virtual line Y to the other virtual line Y) are the construction range of the roofing material 3. Thus, in this embodiment, the construction range of the roofing material 3 is clear, and more accurate construction of the photovoltaic roof 100 is possible.

In the construction step S3 shown in FIG. 6, the second drainer 142 is attached to the first drainer 141.
