Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a solar cell panel placed on the roof of a house to generate solar power.

0002

[Prior Art] As a solar cell placed on the roof of an ordinary house to generate solar power, a Japanese tile type solar cell panel with the same curved surface shape as the Japanese tiles placed on the roof of an ordinary house is used. A slate tile type with a flat surface like a slate tile has been proposed.

0003

[Problem to be solved by the invention] Since the Japanese tile type can be used in place of regular Japanese tiles, no special consideration is required when installing it on the roof. However, the light-receiving surface of the solar cell is curved. Therefore, the manufacturing process is complicated, and there are problems in terms of cost.

On the other hand, since the receiving surface of the slate tile type is flat, it is easy to form a solar cell, but a means for arranging it on the roof is essential. The most common method is to make holes for direct mounting on the flat board that serves as the base plate, and then screw them to the roof surface through those holes. Because of this, it is difficult to tighten the screws consistently, and there are problems such as insufficient tightening causing leaks, or conversely, over tightening causing the board itself to break.

Particularly in the case of this type of solar cell panel, it is essential that the flat substrate be transparent to light, and considering that tempered glass is usually used for this purpose, cracking of the substrate has been a major problem.

[0006]

[Means for Solving the Problems] The present invention has been made to solve the above problems, and provides a solar cell panel in which solar cells are adhered to a flat transparent glass substrate, the transparent glass substrate This is a structure in which a plurality of mounting pieces for attaching the solar cell panel to the roof surface are protruded from the roof, and the solar cell panel is attached to the roof surface via the mounting pieces.

More specifically, a solar cell is attached to one side of a transparent glass substrate, and a plurality of mounting pieces for attaching the solar cell panel to the roof surface are attached to the other side of the transparent glass substrate. This is a structure in which the solar cell panel is attached to the roof surface via a protruding mounting piece.

[0008]

[Function] According to the present invention, when installing the solar panel on the roof, no force is applied directly to the transparent glass substrate.
There is no possibility that the glass substrate will be damaged.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 and 2 are a front view and a side sectional view of a solar cell panel employing the structure of the present invention, in which 1 is a transparent glass substrate, which is usually made of tempered glass. The size of this board 1 is about 90 cm on the long side, about 40 cm on the short side, and 0 thickness.
．． It is about 6 cm. A solar cell 2 is attached from the back side along one long side of the substrate 1, and is usually made of amorphous silicon in order to increase the area. As is clear from FIGS. 1 and 2, the solar cell 2 is provided in the lower half of the glass substrate 1 or in an area smaller than that. The reason why the area to which the solar cells 2 are attached is half or less of the total surface of the substrate 1 is that when a slate tile type roof is normally installed, the slope of the roof is higher than when the roof is made of Japanese tiles. This is because the overlap between the slate tiles is extremely large in order to prevent rainwater from seeping in through the gaps between the slate tiles. Specifically, as will become clear from the explanation that follows, most of the areas on the substrate 1 where the solar cells 2 are not provided are areas where tiles overlap each other. Further, the specific structure of the solar cell 2 part is as shown in an enlarged view in FIG. The back surface of the solar cell thin film 4 was then exposed to E again.
After covering with a VA thin film 3, it is covered with a back protection film 5 having a structure in which a thin aluminum film is sandwiched between PET (polyethylene terephthalate) films. It goes without saying that sunlight 6 for solar power generation is irradiated from the glass substrate 1 side.

Reference numerals 7 and 7 denote a pair of mounting pieces fixed with adhesive 8 to the back surface of the transparent glass substrate 1 where the solar cells 2 are not provided, and are used when attaching the solar cell panel to the roof surface. . This mounting piece has a length of 20~
It is composed of a metal plate made of iron or the like and has a size of about 30 cm, a width of about 3 cm, and a thickness of about 0.4 cm, and about half of its length protrudes from the top surface of the transparent glass substrate 1. Also, the mounting points of these mounting pieces 7, 7 are important, and the glass substrate 1
It is necessary that the distance be approximately 1/4 of the length of the substrate 1 from the end face of the substrate 1. The importance of this attachment point will be explained later. FIG. 4 shows a solar cell 2 on a glass substrate 1,
It also shows different mounting structures for the mounting piece 7, in which both the solar cell 2 and the mounting piece 7 are integrally molded with EVA 3, and a back protection film 5 is provided on the back of the integral mold. be. According to this configuration, a larger amount of EVA 3 is required than those in FIGS. 1 and 2, but the assembly process is simplified and the back surface of the glass substrate 1 is flat, so the solar cell panel can be It is expected to improve safety and workability when installed on the roof.

Next, a case will be described in which a solar cell panel having such a configuration is installed on the roof of a house. As shown in FIG. 5, the basic configuration for installation is that panels are installed on the field board 10 at predetermined intervals, specifically at intervals equal to the intervals between the mounting pieces 7, 7 attached to the glass substrate 1 of the solar panel. The mounting pieces 7, 7 are fixed to the crosspieces 11, 11, . . . by screwing or the like. At this time, the area where the solar cell 1 of the next glass substrate 1 is provided is superimposed on the area where the solar cell 2 of the glass substrate 1 is not provided,
As a result, only the solar cell 1 is installed on the roof surface. This overlapping portion of the glass substrate 1 prevents rainwater from entering as described above.

It is also conceivable to arrange the glass substrates 1 in a staggered manner with respect to the crosspieces 11, 11, . . . as shown in FIG. The choice of arranging the solar panels in a staggered manner or in a straight line as shown in FIG.
This is made possible by providing 7 at a position 1/4 from the end surface of the glass substrate 1.

In this way, the beams 11, 11 are placed on the roof board 10.
... and attaching the mounting pieces 7, 7, ... of the solar cell panel to the crosspieces 11, 11..., as shown in FIG. 7, the glass substrates 1, 1 of the solar cell panel
A space corresponding to the thickness of the crosspieces 11, 11... is created between ... and the roofing board 10, and by allowing air to circulate through this space, the solar panel can be inserted from the back side. Can be cooled. Furthermore, if necessary, a configuration can be adopted in which cooling air is forced into the space, and a large cooling effect can be expected.

Generally, as shown in FIG. 1, the power generated by the solar panel is taken out through a pair of positive and negative waterproof connectors 12, 12, etc., and is connected to the side where a large number of each panel is arranged. As shown in Figure 8, the current collection box 1
It is connected to power main lines 14 and 14 via cables 3 and 13, guided into the house, and supplied to predetermined power demand areas. Therefore, if a space as shown in FIG.
can be placed.

On the other hand, mechanical attachment of the solar panel is carried out using attachment pieces 7, and electrical output is taken out using connectors 12, 12, as shown in FIGS. 1 and 8.
Although this is done through the above, it is also possible to do both at the same time. That is, as shown in FIG. 9, the mounting pieces 7, 7 are made of a conductive material such as metal, and the mounting pieces 7, 7 serve as both the positive and negative output terminals of the solar cell 2, and the crosspiece 11
, 11 are provided with power main lines 14, 14, and the panels are attached to the crosspieces 11, 11 using the mounting pieces 7, 7, and at the same time electrical connection with the power main lines 14, 14 is also made.

Effects of the Invention As is clear from the above description, the present invention includes a plurality of mounting pieces protruding from a transparent glass substrate of a solar cell panel to which solar cells are attached, for attaching the solar cell panel to the roof surface. Since the solar panel is attached to the roof surface via the mounting piece, no direct force is applied to the transparent glass substrate when installing the solar panel on the roof, so there is no risk of damage to the glass substrate. . Therefore, mounting the solar cell panel on the roof, which is not a good working environment, does not require much attention and can be easily carried out even by workers who are not particularly skilled.
