An embodiment of the present invention will be described below with reference to the drawings. FIGS. 1 and 2 show a solar cell roof 1 of the present embodiment.
Rafters 4 inclined downward from the eaves 3 to the eaves 3, a base plate 5A stuck along the rafters 4, and solar cell panels 10 arranged vertically and horizontally above the base plate 5A. It is a sloping roof. Rafters 4 is one in which both forms the frame of a house and purlins and beams (not shown). Field board 5A
Is a plywood with a waterproof surface material such as asphalt roofing attached to the surface. The roof surface 5 that secures the waterproof performance of the roof 1 is formed by attaching the field board 5A to the entire surface of the roof 1.

The solar cell panel 10 has a standardized size in which a predetermined number of solar cells are accommodated in a flat waterproof case 11. A frame member 12 for reinforcement is attached to the periphery of the solar cell panel 10. With such a structure, the solar cell is protected from accidents such as water leakage and short circuit due to water, and loads applied to the surface. The solar cell panel 10 is provided with a cable 6 for extracting electric power to the outside. Cable 6 is in Building 2
Is wired into the room through a hole 7 formed in the roof surface 5 near the center. The frame member 12 of the solar cell panel 10 is provided with a flange portion 13 extending horizontally to the eave 3 side. This flange 13 is the eaves 3
It is superimposed on the upper surface of the frame member 12 of the solar cell panel 10 adjacent to the side. The gap between the upper surface and the flange portion 13, such as the different solar cell panel 10, the seal member 13A such as urethane foam is put packed. Such a solar cell panel 10 is supported on the roof surface 5 via a rail-shaped member 14 which is a spacing member having a predetermined height.

The rail-shaped member 14 is an elongated tubular member having a substantially rectangular cross section. On the roof surface 5, a pair of rail-shaped members 14 are laid in parallel at intervals according to the width of the solar cell panel 10, and support both ends of the solar cell panel 10. Thereby, a gap 15 is formed between the solar cell panel 10 and the roof surface 5, and air for cooling the solar cell panel 10 flows through the gap 15. At both ends of the solar cell panel 10 arranged on the pair of rail-shaped members 14, adjustment surface materials 16 and 17 are respectively arranged in parallel with the roof surface 5. The adjustment surface members 16 and 17 are surface members arranged adjacent to the solar cell panel 10 at the ends arranged on the rail-shaped member 14, and have a thickness smaller than that of the solar cell panel 10. .

In addition, the dimension of the sides of the adjustment surface materials 16 and 17 along the inclination direction, in other words, the length of the intersection side that intersects with the adjacent side, that is, the depth size, is determined by the two adjustment surface materials 16 and 1.
The sum of 7 corresponds to the difference between the slope length L from the ridge 2 to the eave 3 of the roof surface 5 and the total length 1 of the row of the solar panel 10. In other words, the depth dimension of the adjustment face materials 16 and 17 is set to a length that compensates for the lack of the full length 1 with respect to the gradient length L. That is, the depth dimension of the adjustment surface material 16 arranged on the ridge 2 side is defined as a length m from the uppermost edge of the solar cell panel 10 to the ridge 2 which is the nearest edge of the roof surface 5. The depth dimension of the adjustment surface material 17 disposed on the third side is determined by the distance from the bottom edge of the solar cell panel 10 to the roof surface 5.
Is the length n up to the eave 3 which is the nearest edge of.

The adjusting surface member 16 is fixed to the roof surface 5 via a square member 20 having a height larger than that of the rail-shaped member 14. Thereby, the upper surface of the adjustment surface member 16 and the upper surface of the frame member 12 of the solar cell panel 10 form the same surface. On the other hand, the adjusting face member 17 is placed and fixed on the rail-shaped member 14, and a net-shaped member 21 having countless fine through holes is interposed between the adjusting face member 17 and the roof surface 5. The mesh member 21 has a honeycomb shape having a through hole whose overall length is longer than the diameter. The opening on the eaves 3 side of the gap 15 formed between the solar cell panel 10 and the roof surface 5 is closed by the mesh member 21 so that ventilation and water can pass therethrough, so that pests and the like can be prevented from entering the gap 15. In addition, the load of the adjusting face member 17 is supported. The opening of the gap 15 on the ridge 2 side communicates with the hollow portion 2A provided inside the ridge 2. This hollow part
2A has an opening communicating with the outside, and this opening is permeable to air by a mesh member 22 having the same structure as the mesh member 21. By discharging the air in the gap 15 from the mesh member 22, the solar cell panel 10 can be cooled.

In this embodiment, after the roof surface 5 of the roof 1 is completed, the rail-shaped members 14 and the square members 20 are laid, holes 7 are formed in the roof surface 5, and then the solar cell panel 10 is formed. To the rail-shaped member 14, and
The net-like member 21 is attached near the portion to be the opening on the 15 eave 3 side. After that, the roof 1 is completed by attaching the adjusting surface materials 16 and 17. Here, the adjustment face materials 16 and 17 can be manufactured on site by attaching the solar cell panel 10 to the roof surface 5 and then determining the depth dimension based on the result of actually measuring the dimensions m and n. When the dimensions of the roof 1 are determined at the time of designing the building, the dimensions of the adjusting face materials 16 and 17 are determined in advance, and the adjusting face materials 16 and 17 are manufactured in advance at a factory or the like. It is desirable.
