DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar cell roof in which a plurality of solar cell modules are provided on a roof surface in a vertical and horizontal direction, and a snow stopper structure for the solar cell roof.

[0002]

2. Description of the Related Art A solar cell roof and a snow stopper structure of the solar cell roof are known, for example, from JP-A-8-13725. As shown in FIG. A plurality of solar cell panels 51 are arranged side by side on a sloped roof surface 53 of a building 52. As shown in FIG. 10, the solar cell panel 51 is supported by the frame 54 via a support member 55 at the opening of the frame 54 and having a substantially rectangular shape in a plan view. A solar cell portion 56 is provided, and a concave portion 57 formed integrally with the frame 54 in advance, and a concave portion 57 formed between the upper surface of the frame portion 58 of the frame 54 and the upper surface of the solar cell portion 56 in advance. The stepped portion D serves as a snow stopper that prevents falling snow on the roof that tends to slide down along the inclination direction.

[0003]

Incidentally, the amount of snow varies depending on the area. When a snow stopper is installed on a solar cell roof in accordance with the amount of snow, as described above, a conventional solar cell is used. Since the snow stopper structure of the roof is provided with the snow stopper portion integrated in advance in the solar cell panel body, the snow stopper portion can be changed to a snow stopper portion having a shape corresponding to the amount of snow, or the number of the snow stopper portions can be reduced. It was technically difficult to increase or decrease as necessary. In addition, since the power generation efficiency is reduced when dust and dirt adhere to the solar panel, periodic cleaning of the surface is required. However, since the solar panel is provided on the roof surface, work is required on the roof surface. It is difficult to secure a stable work place when performing maintenance such as cleaning, and the workability is poor.

Accordingly, the present invention has been made in view of the above circumstances, and a required number of snow stoppers corresponding to the amount of snow can be easily attached to a solar battery roof, and a work place on the roof surface is required. It is an object of the present invention to provide a solar cell roof and a snow stopper for the solar cell roof, which can secure and improve workability.

The photovoltaic module can also be installed so as to span the solar cell modules arranged adjacent to each other vertically and horizontally. Also,
Since the required number of the snow stoppers can be prepared and installed on the upper surface of the solar cell module in accordance with the amount of snow, it is possible to reduce the labor and cost of preparing an extra snow stopper. it can.

According to the solar cell roof according to the fifth aspect of the present invention, the same effects as those of the first to fourth aspects can be obtained. Since the provided snow stopper is provided, the hook of the lifeline can be hooked on any of these hooks, so that work can be freely and easily performed everywhere on the solar cell roof. Furthermore, when the snow stoppers are sandwiched and engaged between the solar cell modules that engage with each other, the snow on the snow stoppers and the weight of the worker depend on the inclination direction of the roof surface. Since it can be sufficiently supported by the solar cell module via the surface of the orthogonal snow stopper, it is possible to simplify the reinforcement when the hanging portion is provided on the snow stopper.

According to the sixth aspect of the present invention, in the solar cell roof snow stopper structure according to any one of the first to fifth aspects, the snow stopper member corresponds to the amount of snow. The snow stopper can be attached to a smaller area in an area where the amount of snow is small.

Claims (6)

[Claims] 1. A solar cell roof in which a plurality of solar cell modules are provided vertically and horizontally on a roof surface of a building, wherein a plurality of solar cell modules are arranged vertically adjacent to each other on an inclined roof surface. A snow stopper that protrudes above the upper surface of the solar cell module from above, wherein the snow stopper is separate from the solar cell module and is sandwiched between solar cell modules arranged vertically adjacent to each other. A solar cell roof comprising: a sandwiched portion to be held; and a snow stopper extending from the sandwiched portion to above the upper surface of the solar cell module. 2. The solar cell roof according to claim 1, wherein the solar cell modules arranged vertically adjacent to each other are provided with engaging portions on sides that are in contact with each other, and the engaging portions are engaged with each other. By doing so, the upper and lower solar cell modules are connected, and the held portions of the snow stopper are sandwiched between the engaging portions engaged with each other and engaged with these engaging portions. And solar roof. 3. The solar cell roof according to claim 1, wherein the snow stopper has a fixing portion extending below the solar cell module from the pinched portion and fixed to the roof surface. A solar cell roof characterized by being made. 4. A solar cell roof in which a plurality of solar cell modules are provided vertically and horizontally on a roof surface of a building, wherein each solar cell module has a snow stopper extending upward from an upper surface of the solar cell module. A solar cell roof, wherein a member is detachably attached. 5. The solar cell roof according to claim 1, wherein the snow stopper is provided with a lifeline at a portion protruding from an upper surface of the solar cell module when working on the solar cell roof. A solar cell roof, wherein a hook portion for hanging is provided. 6.
