DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a method for arranging solar cell modules.

[0002]

2. Description of the Related Art Conventionally, solar cells have been used to effectively utilize solar energy as electricity. When a solar cell is used, generally, a rectangular flat-panel solar cell panel in which a predetermined number of solar cells are incorporated in a frame-like frame is used as a solar cell module, and the solar cell panel is used as a roof, road, or ground. (See Japanese Patent Application Laid-Open No. 7-180310).

[0003]

However, in the conventional arrangement method, since the solar cell panels are simply arranged in the vertical and horizontal directions, the design is not considered and the appearance is good. Did not.

An object of the present invention is to provide a method for arranging solar cell modules that can have a good appearance, for example, when the whole is viewed from a distance.

[0005]

The method for arranging solar cell modules according to the present invention is described with reference to the reference numerals used in the embodiments, and is a method for arranging solar cell modules 1 having solar cells 12 provided therein. While arranging a plurality of solar cell modules in a direction in which solar rays hit the solar cells,
It is characterized by being arranged so as to form at least one of characters, symbols and patterns.

According to the present invention, by using, for example, a solar cell provided in each solar cell module as one dot, a variety of characters, symbols,
The pattern can be easily drawn, and the appearance becomes better as compared with the conventional case where the pattern is simply arranged in the vertical direction and the horizontal direction.

At this time, the solar cell modules may be arranged in a vertical direction and a horizontal direction when viewed from the position where the characters, symbols and patterns are viewed from the normal direction, or may be arranged in an oblique direction. By changing the arrangement of the solar cell modules, the design of characters, symbols, and patterns can be varied. In addition, by changing the arrangement of the solar cell modules, it is possible to set the characters and symbols to be visible from any direction while the solar cell modules are directed to the south side, which is advantageous for power generation. As described above, each solar cell module can be installed at the minimum front-rear pitch, and the amount of power generation per unit installation area can always be maximized.

In the present invention, the solar cell module may include a three-dimensional frame 11, and the characters, symbols, and patterns may be formed using at least one surface of the frame. In such a case, even if the solar cell modules are arranged on a horizontal plane, characters, symbols, and patterns are formed on one side of the frame that rises up to this horizontal plane, so that characters can be displayed even from a not so high position. , Symbols and patterns can be visually recognized with certainty.

[0009] In the frame, a surface 11A on which the solar cells are provided may be different from a surface 11C on which the characters, symbols, and patterns are formed. In such a case, unlike the case where characters, symbols, and patterns are formed on the surface on which the solar cells are provided, there is no limitation on the color or shape of the dots. Therefore, it is possible to form more various characters, symbols, and patterns. In addition, it is possible to provide a large number of solar cells regardless of the shape and size of characters, symbols, and patterns to be expressed, and it is possible to generate more power than in the case where solar cells are used as dots.

As described above, by attaching the solar cell units 10 to the rails 3 while connecting them, the solar cell modules 1 of this embodiment are arranged to form an "M" shape. In the case where the solar cell modules 1 are electrically connected to each other, the wiring is connected to the wiring space 3A in the rail 3.
To be stored.

According to this embodiment, the following effects can be obtained. 1) Each of the solar cells 12 (solar cells) of blue or various colors provided in each solar cell module 1 is used as one dot, and the number of connected solar cell units 10 having the solar cells 12, Since the number and direction of arrangement of the solar cell modules 1 constituted by the solar cell units 10 are set to clearly draw the "M" shape, the conventional solar cell modules 1 are simply arranged in the vertical and horizontal directions. The appearance can be improved as compared with.

2) The solar cell module 1 is vertically
In addition to the arrangement in the rows, the arrangement in the first to third rows also in the horizontal direction allows characters having a complicated shape such as an "M" shape to be reliably formed, thereby increasing the variety of characters that can be formed.

3) The solar cell module 1 includes a plurality of solar cell units 10.
Is configured to include the hollow triangular prism-shaped frame 11,
Even if the solar cell modules 1 are arranged on the horizontal installation part 2, the "M" shape can be formed by the slope 11A raised up to the installation part 2, and even if the view from a position not so high is "M". The "" shape can be visually confirmed.

4) The frame 11 is an isosceles triangle with a right-angle cross section, and the rear surface 11C is arranged so as to be vertical. Therefore, when viewed not only from a position not so high but also from a direction directly above. However, only the slope 11A can be seen, and the "M" shape can be visually recognized even from a higher position.

5) Since the "M" shape is drawn using the blue color of the solar cell constituting the solar cell 12, it can be drawn with a unique color unique to ordinary paints. The appearance can be further improved.

Second Embodiment FIG. 5 shows a solar cell module 1 having an "A" shape formed by the arrangement method of the second embodiment. In the present embodiment, the arrangement of the solar cell modules 1 is significantly different from that of the first embodiment. That is, the solar cell modules 1 of the present embodiment are arranged in a state of being inclined in an oblique direction when the “A” shape is viewed from the normal viewing position. However, also in the present embodiment, the solar cell module 1 is configured by the same solar cell unit 10 as the first embodiment,
The slope 11A (light receiving surface) of each solar cell unit 10 faces the south side. Other configurations are the same as the first embodiment,
Here, the description is omitted.

According to the present embodiment, 1) and 3) described above.
5) can be obtained in the same manner, and the following effects can be obtained. 6) Since the respective solar cell modules 1 are arranged at an angle, the design can be different from the case where the "A" shape is formed by arranging in the vertical and horizontal directions as in the first embodiment, for example. Variations can be increased. That is, even if the configuration is different from that of the first embodiment, the above-described effect 2) can be obtained similarly.

7) In the first embodiment described above, in order to reliably generate electric power, it is necessary to match the vertical direction of the character with the north-south direction, and thus to turn the slope 11A to the south side. Although the direction (direction) to perform is limited, in the present embodiment, since the inclined surface 11A can be directed to the south side by inclining each solar cell module 1, the vertical direction of the characters does not necessarily match the north-south direction. There is no need to perform this operation, and the degree of freedom in forming characters can be increased. That is, the layout can be made so that the amount of power generation per unit installation area is maximized.

[Third Embodiment] FIG. 6 shows an example in which an "S" shape is formed by the arrangement method of the fifth embodiment. In the present embodiment, the solar cell modules 1 including the same number of solar cell units 10 are arranged only in the vertical direction. Moreover, the cross-sectional shape of each solar cell unit 10 is substantially a regular triangle as schematically shown in the figure, and the “S” shape is the back surface 11 of the solar cell unit 10.
C, that is, a surface opposite to the inclined surface 11A, which is a light receiving surface, is used.

In this embodiment, the flat back surface 11C is painted in a color different from that of the back surface 11C, or a color sheet is pasted on the flat back surface 11C to form an "S" -shaped portion. When the battery module 1 is viewed from the north side (in the direction of the dashed-dotted arrow), an “S” shape appears as a whole.

According to the present embodiment, the following effects can be obtained. 8) Since a colored portion is provided in a part of the solar cell module 1 and this portion is formed as a dot to form an "S" shape, the appearance can be improved as compared with the related art. Therefore,
Although the configuration is different, the above-mentioned effect 1) can be obtained similarly.

9) In the first and second embodiments, the characters are drawn in the blue color of the solar cells. However, in the present embodiment, the characters are not drawn by the solar cells. Color can be freely selected to draw characters of any color, and the degree of freedom in design can be greatly increased.

10) In the first and second embodiments, since the solar cell unit 10 having a predetermined length is one basic dot, it is difficult to smoothly draw a curve or the like. On the other hand, in the present embodiment, since a part to be colored and a part not to be colored in one solar cell unit 10 can be formed, a character having a curve such as an “S” shape can be formed more clearly.

11) Furthermore, in the first and second embodiments, power is generated only by the solar cell units 10 forming characters, but in this embodiment, a large number of solar cell units 10 not forming characters are used. For example, when the same character is formed, the amount of power generation can be increased.

It should be noted that the present invention is not limited to the above-described embodiment, but includes other configurations that can achieve the object of the present invention, and the following modifications are also included in the present invention.
For example, in each of the above embodiments, the solar cell module 1
(Solar cell unit 10) is a frame 1 having a triangular cross section
However, the solar cell module according to the present invention may be a rectangular flat panel solar cell panel as described in the conventional example, and as shown in FIG. 'May be arranged on the roof surface to form characters or the like.

Further, even when the solar cell module is configured to include a frame, the shape of the frame is not limited to a triangular cross section, but may be arbitrary, for example, a trapezoidal cross section or a circular arc cross section.

Further, each solar cell 12 (solar cell)
Is used as one dot, the size of such a solar cell 12 is also arbitrary. In other words, by using smaller and smaller solar cells, especially in the case of drawing letters, symbols, and patterns as in the first embodiment,
Curved portions can be formed more clearly.

In the present invention, what is formed by the solar cell module may be not only characters but also symbols and patterns. Furthermore, you may form combining a character, a symbol, and a pattern.

[0046]

As described above, according to the present invention,
By using, for example, solar cells provided in individual solar cell modules as one dot, various characters,
Symbols and patterns can be easily drawn, and there is an effect that the appearance can be improved as compared with the related art in which the symbols and patterns are simply arranged in a vertical direction and a horizontal direction.
