Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slate tile type solar cell module which is arranged as a roof tile on a roof of a house to generate solar power, a roof mounting member for the slate tile type solar cell module, and a slate tile type. The present invention relates to a method for mounting a solar cell module on a roof.

[0002]

2. Description of the Related Art As a solar cell for arranging on the roof of a house of a general household for photovoltaic power generation, a Japanese tile type solar cell module having the same curved shape as the Japanese tile arranged on the roof of an ordinary house. And, a slate roof type solar cell module having a flat plate shape like a slate roof has been proposed.

[0003]

Since the Japanese tile type can be directly replaced with the ordinary Japanese tile, no special consideration is required for installation on the roof, but the light receiving surface of the solar cell has a curved shape. Therefore, the manufacturing process is complicated, and it is said that there is a difficulty in cost.

On the other hand, the slate roof tile type has a flat light-receiving surface, so that it is easy to form a solar cell, but a means for arranging it on the roof is indispensable. The most common method is to provide a hole in the main body of the glass substrate for attachment and screw it to the roof surface through the hole. If tightened too tightly, there is a problem such as breaking the board itself. In addition, since the work is performed on a roof where the working environment is extremely poor, a simpler mounting method is desired in order to secure the work safety and speed the work.

In view of the above circumstances, it is an object of the present invention to provide a structure and method for easily mounting a slate tile type solar cell module on a roof.

[0006]

In order to solve the above-mentioned problems, the slate roof tile solar cell module of the present invention comprises a plate-shaped member to form a main body, which is a rear area where roof tiles are stacked on the roof. The solar cell is attached to the area excluding the area, and a ring-shaped locking member is provided on the lower surface of the rear area.

The roof mounting member of the slate tile type solar cell module of the present invention is formed by connecting a plurality of pipe-shaped support rods, and each pipe-shaped support rod has an engaging portion for connecting pipes. And a mounting portion for forming a fixed interval with respect to the base plate and mounting it on the base plate.

Further, in the method for mounting the slate tile type solar cell module on the roof of the present invention, a plurality of pipe-shaped support rods are directed in the same direction as the inclination direction of the roof and are parallel to each other with a certain space therebetween on the field board. , The ring-shaped locking member provided in the slate roof tile solar cell module is fitted into the pipe-shaped support rod, and then the pipe-shaped support rod of the next stage is connected to the pipe-shaped support rod. It is characterized in that the ring-shaped locking member provided on the slate roof tile solar cell module of the next stage is fitted on the base plate and fitted into the pipe-shaped support rod of the next stage repeatedly.

[0009]

According to the first construction described above, the slate tile type solar cell module can be easily fixed on the roof by fitting the ring-shaped locking member into the pipe-shaped support rod. The property is improved. Further, since the slate roof tile solar cell module is attached by the above-mentioned pipe-shaped support rod, there will be no problem such as breakage of the glass substrate when fixed by screwing. Further, the ring-shaped locking member is fitted into the pipe-shaped support rod so that it can be easily positioned.

Further, according to the second structure, the roof mounting member is formed by connecting a plurality of pipe-shaped support rods, but each pipe-shaped support rod can be easily handled. It is possible, and it can be easily mounted on the field board at its mounting portion. Furthermore, the above-mentioned roof mounting member eliminates the need for a shackle.

Further, according to the third structure, the pipe-shaped support rods → the solar cell module → the pipe-shaped support rods may be alternately arranged on the roof, so that even a so-called unskilled person can comparatively arrange them. The solar cell module can be easily mounted on the roof. Further, when the solar cell modules are arranged on the roof in this way, a gap is formed by interposing the pipe-shaped support rods between the solar cell modules and the ground plate. Since the air is passed through, the temperature rise of the solar cell can be suppressed and the output reduction can be prevented.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings showing its embodiments.

1A and 1B are views showing a slate roof tile solar cell module 10 of the present invention. FIG. 1A is a plan view thereof, and FIG. 1B is a sectional view taken along the line AA.

In the figure, reference numeral 1 denotes a metal plate which constitutes the main body of the slate roof tile type solar cell module, and is composed of a stainless plate or an iron plate coated with anticorrosion. The metal plate 1 has a long side of about 60 to 90 cm, a short side of about 40 cm, and a thickness of 0.
It is about 5 to 1 mm. It should be noted that the sizes of the above-mentioned parts are merely examples, and the sizes are not limited to these. Further, the metal plate 1 is bent at a substantially central portion to form a step shape. The bending depth matches the thickness of the bonding structure of the solar cell 2 described later, and the width of the bent lower side matches the width of the bonding structure of the solar cell 2.

Reference numeral 2 in the figure denotes a solar cell which is attached from the front surface side along one side of the long side of the metal plate 1, and is usually made of amorphous silicon for increasing the area. The solar cell 2 is provided in the lower half of the metal plate 1 or in an area less than that. The reason why the area of the solar cell 2 attached is half or less than the entire surface of the metal plate 1 is that when the roof is usually a slate tile type roof, and the slope of the roof is a Japanese tile. This is because the tiles are considerably loose compared to each other, and the overlapping portion of the tiles is extremely large because it is necessary to prevent rainwater from seeping through the gaps between the slate tiles. Specifically, as will be apparent from the description below, most of the rear end side region of the metal plate 1 where the solar cell 2 is not provided is the overlapping region of roof tiles.

Next, the attachment structure of the solar cell 2 will be described. As shown in FIG. 1B, this pasting structure is provided on the first adhesive layer 3a made of an adhesive provided on the metal plate 1 and on the first adhesive layer 3a. The solar cell 2 thus formed, the second adhesive layer 3b made of an adhesive provided on the solar cell 2, and the transparent cover glass 4 placed on the second adhesive layer 3b. It is configured, and the sealing structure of the solar cell 2 is realized by this structure.

Such a structure is manufactured by the following method. For example, a cover glass 4, an EVA (ethylene vinyl acetate) sheet to be the first adhesive layer 3a, a solar cell 2, and a solar cell 2 are provided in a lower chamber in a vacuum container separated into an upper chamber and a lower chamber by a flexible silicon sheet. E to be the adhesive layer 3b of No. 2
Set the VA sheet and the metal plate 1 in this order,
Vacuum both lower chambers. Then, the above sample is heated to about 100 ° C. by a heater to melt the EVA sheet. Next, the upper chamber is leaked to atmospheric pressure. At this time, the silicon sheet separating the upper chamber and the lower chamber is pressed against the sample by the pressure difference between the upper chamber and the lower chamber, whereby the sample is brought into close contact with and integrated with the sample. Finally the sample at 150 ℃,
The EVA is crosslinked (stabilized) by heating for about 30 minutes. As a result, the above-mentioned sticking structure is obtained.

At a portion of the metal plate 1 where the solar cell 2 is not provided, that is, in a rear end side area where the roof tiles are overlapped with each other, the solar cell module is mounted on the roof 1 as will be described later.
6, a pair of ring-shaped locking members 15a, 15 for attaching to
Two sets of b are provided. Ring-shaped locking members 15a, 15b
Are fixed to the metal plate 1 by screws 20. Further, in each set of the ring-shaped locking members 15a and 15b, the ring-shaped locking member 15b is formed higher than the ring-shaped locking member 15a. Then, these ring-shaped locking members 15a, 15a
The distance from the side surface of the metal plate 1 in the space (between 15b and 15b) is set to 1/4 of the entire width of the metal plate 1.

Next, the case where the solar cell module 10 having such a structure is installed on the roof of a house will be described.
For this installation, as shown in FIG. 2 and FIG. 3, roof mounting members 16 ... Are used. Then, the solar cell modules 10 are arranged, for example, in a staggered manner (in a staggered arrangement) by the roof mounting members 16 ... Hereinafter, the configuration of the roof mounting member 16 ... And the procedure for installation will be described.

The roof mounting member 16 is, for example, a pipe-shaped support rod 1 made of metal such as aluminum or synthetic resin.
It is configured by connecting a plurality of 7. Pipe-shaped support bar 17
Is provided with an engaging portion 18 for connecting the pipes to each other, and an attaching portion 19 for forming a fixed interval with respect to the base plate 11 and attaching the same to the base plate 11.

The above-mentioned engaging portion 18 is used for each pipe-shaped support rod 1.
7 are formed at the front and rear ends, respectively. One is a male side engaging portion 18b and the other is a female side engaging portion 18a.

The mounting portion 19 has a leg portion that hangs bifurcated from the pipe-shaped support rod 17, and a screw fixing hole (not shown) is formed in each leg portion. Since the mounting portion 19 is mounted near the male-side engaging portion 18b of the pipe-shaped support rod 17, the ring-shaped locking members 15a and 15b can be attached to the pipe-shaped support rod 17 without being disturbed by this.
Can be fitted into. Further, in this fitting, the slate roof tile solar cell module is positioned by bringing the ring-shaped locking member 15b into contact with the mounting portion 19.

Next, the installation procedure will be described. The solar cell module is installed from the lower side of the roof. First, the first
The pipe-shaped support rods 17 of the tiers are attached on the field board 11 in the same direction as the roof inclination direction and in parallel with each other at a constant interval (corresponding to the distance between the two sets of ring-shaped locking members). . This mounting is performed by screwing a screw into the screw fixing hole of the mounting portion 19. Next, the solar cell module 10 of the first stage is connected to the pipe-shaped support rod 1 of the first stage.
Attach to 7. This attachment is performed by the ring-shaped locking members 15a, 1
5b is fitted into the pipe-shaped support rod 17 to carry out.

The first-stage solar cell module 10 ...
After the installation of the, the second stage pipe-shaped support bar 17 ...
Are connected to the first-stage pipe-shaped support rods 17, which are arranged in advance, and are fixed to the base plate 11. The connection is performed by fitting the male side engagement portion 18b of the second stage pipe-shaped support rod 17 into the female side engagement portion 18a of the first stage pipe-shaped support rod 17. Also, fixing to the base plate 11 is the same as above.
This is performed by screwing a screw into the screw fixing hole of the mounting portion 19.

Then, the solar cell modules 10 ... Are attached to the above-mentioned second stage pipe-shaped support bar 17. This installation is done in a staggered arrangement. By repeating the above steps, the solar cell modules 10 ... Are mounted on the roof. As described above, the ring-shaped locking member 15a,
Since the distance from the side surface of the metal plate 1 between 15a (between 15b and 15b) is set to 1/4 of the total width of the metal plate 1, such a staggered arrangement is possible.

As described above, the ring-shaped locking member 15
Since the slate roof tile solar cell module 10 can be easily fixed on the roof by fitting the pipes a and 15b into the pipe-shaped support rod 17, the workability of mounting on the roof is improved. Further, the solar cell module 10 is attached by the pipe-shaped support rod 17 described above, and there is a problem in fixing with a screw, for example, the glass when the main body of the solar cell module 10 is made of a glass substrate. Problems such as substrate cracking will not occur. In addition, the ring-shaped locking members 15a and 15b are connected to the pipe-shaped support bar 17

Further, the roof mounting member 16 is formed by connecting a plurality of pipe-shaped support rods 17, but the individual pipe-shaped support rods 17 can be easily handled. Moreover, it can be easily mounted on the field board 11 at its mounting portion. Further, by providing the above-mentioned roof mounting member 16 ..., a pier is unnecessary.

In addition, in the method of mounting the slate tile type solar cell module on the roof, the pipe-shaped support rods 17 → the solar cell module 10 → the pipe-shaped support rods 17 may be alternately arranged on the roof. The so-called unskilled person can relatively easily mount the solar cell module 10 on the roof. Further, when the solar cell modules 10 are arranged on the roof in this way, a gap is formed between the solar cell modules 10 and the base plate 11 at the height of the mounting portion 19 and the ring-shaped locking member 15b. Since air will pass through this gap, the solar cell 2
It is possible to suppress the temperature rise and prevent the output from decreasing.

Further, since the solar cell module 10 is arranged while being held at a constant angle by the ring-shaped locking members 15a and 15b, the front surface of the module 10 arranged first and the back surface of the module 10 arranged later are arranged. It will be harder to create a gap between them, which will eliminate problems such as rain leaks and wind-up of roof tiles.

In this embodiment, the main body of the slate roof tile solar cell module is made of the metal plate 1, but it may be made of a glass substrate.

[0031]

As described above, according to the present invention, the slate roof tile solar cell module can be easily attached to the roof. In addition, the positioning of the module can be prevented, and the roof tiles can be prevented from being leaked due to rain leaks or wind. Further, it is possible to reduce the weight while maintaining the strength against bending and the reliability against wind pressure, and it is possible to improve the workability of mounting the solar cell module on the roof. Furthermore, the effect of preventing a decrease in the output of the solar cell due to the improved heat dissipation is also exhibited.
