Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof with solar cells, in which a plurality of solar cell panels for receiving sunlight and converting it into electric power are arranged vertically and horizontally on a roof surface.

[0002]

BACKGROUND ART Conventionally, solar energy has been known as clean energy which does not adversely affect the environment and ecosystem. In using solar energy, a solar cell that converts sunlight into electricity is used. In order to make such a solar cell usable at home, a roof with a solar cell in which a solar cell is installed on a roof surface is known. Solar cells installed on roofs with solar cells need to prevent accidents such as short circuit and short circuit due to water.Solar cells, which are solar cells, are housed inside a flat, completely waterproof case, and solar panels It is installed as. This solar cell panel has a predetermined number of solar cells so that a predetermined voltage and power can be obtained by one sheet (see Japanese Patent Application Laid-Open No. H10-140770).

[0003] Here, the gabled roof has a flat rectangular roof surface, so that solar cell panels of the same shape may be adhered to each other. Generally, a flat rectangular solar cell panel, a so-called fixed solar panel, is used. Battery panels are used. On the other hand, the ridge roof has a flat triangular and trapezoidal roof surface. In addition, a solar cell panel having a plane triangular or trapezoidal shape, that is, a so-called irregular solar cell panel is used.

[0004]

However, when a fixed solar cell panel and a deformed solar cell panel are used in combination like a building roof, the light receiving area of the fixed solar cell panel and the deformed solar cell panel is reduced. And the number of solar cells forming the light receiving surface is different, so that the electrical characteristics are different. For this reason, in such a solar cell panel, when electrically connecting the solar cell panels, there is a problem that the electrical handling of the solar cell panels becomes complicated.

[0005] It is an object of the present invention to provide a roof with solar cells, which facilitates electrical handling of solar cell panels.

[0006]

The present invention will be described with reference to the drawings. A plurality of solar cell panels 30, 50 for receiving sunlight and converting it into electric power are arranged vertically and horizontally on roof surfaces 14, 15. A fixed solar cell panel (for example, a rectangular solar cell panel 30) having a rectangular planar shape, and a deformed solar cell panel (for example, a trapezoidal shape) having a different planar shape from the fixed solar cell panel. The solar cell panel 50), the fixed-shaped solar cell panel has a light receiving surface 37 for receiving sunlight, and the deformed solar cell panel has a deformed light receiving surface 58 different in shape and area from the light receiving surface 37. The electrical characteristics obtained by combining a plurality of the modified light receiving surfaces 58 of the modified solar cell panel are substantially the same as the electric characteristics obtained by the light receiving surface 37 of the fixed solar cell panel. And wherein the door. According to the present invention, for example, when a fixed roof panel is roofed by combining a fixed-shaped solar cell panel and a deformed solar cell panel, the dimensions of the deformed solar cell panel are set according to the dimensions of the fixed-shaped solar cell panel. It is not necessary to consider the difference in electrical characteristics between the fixed-form solar cell panel and the irregular-shaped solar cell panel as compared with the related art. This facilitates electrical handling of the solar cell panel.

[0007] In the above, the above-mentioned deformed solar cell panel (for example, trapezoidal solar cell panel 50) has the deformed light receiving surface 5
8 and a predetermined number of solar cells 57 for generating electricity with sunlight.
A light receiving surface 58A and a second light receiving surface 58B;
It is preferable that the solar cells 57 forming the first deformed light receiving surface 58A and the second deformed light receiving surface 58B are respectively provided in deformed cases (for example, the case 51) having substantially the same planar shape. As described above, if the deformed cases provided with the solar cells forming the first deformed light-receiving surface and the second deformed light-receiving surface have substantially the same planar shape, two deformed solar cell panels having the same configuration may be combined. So
It is possible to improve the productivity of the solar cell panel.

A solar cell 57 forming the first irregularly shaped light receiving surface 58A and the second irregularly shaped light receiving surface 58B is
The shape of the solar cells 36 forming the light receiving surface 37 of the fixed-shaped solar cell panel is substantially the same as that of the solar cells 36, and the sum of the numbers of the solar cells 57 forming the first modified light receiving surface 58A and the second modified light receiving surface 58B, respectively, is Is desirably the same as the number of solar cells 36 that form. As described above, if the shape of the solar cell used in the deformed solar cell panel is made substantially the same as the shape of the solar cell used in the fixed-shaped solar cell panel, a specially shaped solar cell becomes unnecessary, so that the deformed solar cell panel is manufactured. In doing so, the types of components hardly increase, and from this point, the productivity of the solar cell panel can be improved. Furthermore, if the number of solar cells having the same shape is the same in the fixed-shaped solar cell panel and the two modified-shaped solar cell panels,
Since the obtained electric power is substantially the same, it is possible to easily adjust the electric characteristics, thereby making it easier to handle the solar cell panel electrically.

Further, a deformed frame (for example, a frame 52) surrounding the deformed case is provided on the periphery of each of the deformed cases (for example, the case 51).
It is preferable that the two deformed frames have substantially the same plane shape and are provided on the same plane of the roof surfaces 14 and 15. Here, as the planar shape of the two deformed frame bodies, for example, when a solar cell panel is provided on a flat trapezoidal roof surface of a wing roof, the solar cell panel is formed according to a portion where a fixed solar cell panel is not provided. Can be adopted. If the two deformed frames have substantially the same planar shape, for example, when a solar cell panel is provided on a flat trapezoidal roof surface of a building roof, a margin portion where the solar cell panel is not attached to the roof surface is provided. This does not occur, so that sufficient power can be obtained. Further, if two deformed frames are provided on the same plane of the roof surface, in other words, if the fixed-shaped solar cell panel and the two deformed solar cell panels are provided on the same plane of the roof surface, the amount of sunlight received Are substantially the same, it is possible to make the power obtained by the fixed-shaped solar cell panel and the power obtained by the two deformed solar cell panels the same. As a result, the electrical characteristics can be reliably and easily adjusted, and the electrical handling of the solar cell panel is further facilitated.

Each of the above-mentioned deformed frames (for example, the frame 52) is formed in a substantially trapezoidal plan view.
The area of each of the deformed frames is larger than the light receiving area of each of the deformed light receiving surfaces, and each of the deformed cases preferably has an empty space 59 in which the solar cell 57 is not provided.
In this way, even if each dimension of the deformed solar cell panel is set according to the size of the fixed solar cell panel, it is possible to reliably arrange half of the solar cells provided in the fixed solar cell panel Becomes From this point as well, the electrical characteristics can be surely and easily adjusted, and the electrical handling of the solar cell panel becomes much easier.

Further, the above-mentioned shaped solar cell panel is formed in a flat rectangular shape, and the deformed solar cell panel is formed in a flat trapezoidal shape. It is preferable that the difference from the length A of the bottom is the length C of one side of the fixed solar cell panel. In this way, for example, when a solar cell panel is provided on a flat trapezoidal roof surface of a building roof, it is possible to reliably eliminate a margin portion where the solar cell panel is not stuck, and to maximize the roof surface. It can be used effectively. Thereby, it becomes possible to obtain sufficient electric power according to the size of the roof surface.
