Description

  The present invention relates to an information display apparatus and method for a solar power generation system that displays an image such as a stationary character or a still image using a solar battery panel of the solar power generation system.

In recent years, solar power generation systems have received a lot of interest in solar power generation from the viewpoint of energy saving and environmental protection. It is becoming larger.
However, the roofs of large sites and factory facilities do not exist unconditionally, and the amount of generated power varies depending on geographical conditions such as region, season, installation orientation, and weather conditions. There are various problems to spread and expand the installation of power generation systems. For example, the difficulty in securing a vast place for installing solar cell modules has also been a factor that hinders the spread of solar power generation systems.

As for the sunshine hours, the irradiation angle of sunlight changes in one day, and the irradiation angle of sunlight changes variously depending on the season. Therefore, the stationary solar cell panel has a problem that the maximum power generation cannot be performed because the inclination angle of the solar cell panel is constant, that is, the power generation efficiency is poor.
In order to solve this problem, in the conventional photovoltaic power generation system, as shown in Patent Document 1 and Patent Document 2, for example, the angle of attack of the solar cell panel is tracked (followed) by the movement of the sun and moved. A tracking device has been devised.

Embodiments of the present invention will be described below with reference to the drawings.
Referring to FIG. 1, a photovoltaic power generation system 10 according to this embodiment includes a solar battery panel 12 in which a plurality of solar battery cells 13 are arranged on a plane, and at least one or more solar battery panels 12 on the plane. And a follow-up device 20 that follows each of the solar cell panels 12 in the direction of sunlight irradiation.

  A power conditioner 41 (PCS) that converts DC power obtained from the solar cell module 11 into AC power, and various other components such as a power receiving / transforming facility 42, a power measuring device 43, and a display device 44 are included. Yes. In addition, necessary power is transmitted from the power receiving / transforming equipment 42. In the photovoltaic power generation system 10, at least one or more solar cell modules 11 are arranged on a plane.

On the back surface of the solar cell panel 12, a cell phosphor layer 14 is provided by applying a phosphorescent paint for storing energy received by each solar cell 13 in units of the solar cell 13.
The phosphorescent paint uses a phosphorescent material that absorbs light energy such as sunlight and fluorescent lamps and gradually emits light in the dark. This high-luminance phosphorescent pigment (phosphorescent material) and various resins and additives are used. It is a paint made by mixing. The phosphorescent material, which was mainstream until before 1990, contained radioactive materials, but the alumina-based oxides that have been mainstream since then contain no harmful substances and are safe. In addition, examples of the phosphorescent material include a material in which copper is bonded to zinc sulfide, and a material in which other metal is bonded to strontium aluminate.

The stronger the light energy absorbed, the brighter the paint, the brighter it will continue to emit light for a longer time. For example, in the case of light in the daytime, light is emitted for about 8 hours at night. The emission colors can be used in combination with basic green, blue and red.
Therefore, the plurality of cell phosphor layers 14 display a display image 15 such as a still character or a still image, for example, as shown in FIG. 2, for example, on the entire solar cell panel 12 or the entire solar cell module 11. The display unit 16 is formed.

  The follower 20 is a mechanism that moves the surface of the solar cell panel 12 to be perpendicular to the irradiation angle of the sun that moves during the day, and the angle of attack that adjusts the angle of attack of the solar cell panel 12 according to the tilt angle of the sun. Although it has the adjustment mechanism 21 and the azimuth angle adjustment mechanism 22 which adjusts the azimuth angle of the east-west direction, in this embodiment, the display image 15 of the display part 16 on the back surface in the solar cell panel 12 is displayed especially at night. In order to make it visible, it has the inversion mechanism 23 for turning over at least the solar cell panel 12 (inversion).

  As the follower device 20, as shown in FIG. 1 as an example, a turntable 24 that is rotated in a horizontal direction by a driving device (not shown) is provided as an azimuth angle adjusting mechanism 22 that adjusts the azimuth angle. And on the turntable 24, the solar cell panel 12 is rotatably supported via a bearing portion 27 by a column portion 26 in which a rotating shaft 25 supported substantially in the middle thereof is incorporated. Further, one rotary shaft 25 protrudes outward from the bearing portion 27, and the protruding portion is, for example, a rotation transmission device 28 such as a sprocket or a chain or a rotation drive device 29 such as a motor in accordance with the movement of the sun. An angle-of-attack adjustment mechanism 21 that rotates and adjusts the angle of attack of the battery panel 12 is provided. This angle-of-attack adjusting mechanism 21 also serves as a reversing mechanism 23 for turning over (reversing) the solar cell panel 12.

  Note that the drive device (not shown) of the turntable 24 and the rotation drive device 29 such as the motor of the angle-of-attack adjusting mechanism 21 are connected to the control device 40, and the control device 40 detects the position of the sun (not shown). Based on the signal from the position detection means, the control is performed by giving a command to move the attack angle adjusting mechanism 21 and the azimuth angle adjusting mechanism 22 so that the surface of the solar cell panel 12 is perpendicular to the irradiation angle of the sun.

  From the above, in the daytime, solar power generation is efficiently performed by the solar cell panel 12 following the sunlight irradiation direction by the tracking device 20 based on the command of the control device 40. The generated DC power is converted into AC power by a power conditioner 41 (PCS) and then stored in the power receiving / transforming equipment 42. Simultaneously with such normal power generation, a part of the received sunlight is stored in the cell storage layer 14 on the back surface of the solar battery panel 12. Then, at night, light is emitted from the cell phosphor layer 14.

  Then, based on the instruction | command of the control apparatus 40, it reverse | inverts by turning over the solar cell panel 12 by the tracking apparatus 20. FIG. A timer may be set for inversion of the solar cell panel 12. Since the entire solar cell panel 12 or the entire solar cell module 11 is preliminarily drawn on the back surface of the solar cell panel 12 with a display image 15 such as a stationary character or still image using a plurality of cell storage layers 14. Then, light is emitted from each cell phosphor layer 14 in the dark, and, for example, as shown in FIG. 2, a display image 15 of still characters clearly appears.

Even if the display image 15 is a static character or a still image, the entire solar cell panel 12 or the entire solar cell module 11 becomes a huge advertising panel, so that it can be clearly identified even from a distance and is sufficiently publicized. effective.
Further, when the revolving table 24 is slowly reciprocated by a certain range of angles in the horizontal direction, the display image 15 moves and becomes conspicuous even from a distance, so that the advertising effect can be enhanced.

  When the solar power generation system 10 is installed in a wilderness, a park, an open space in a factory, a rooftop of a factory building, or the like, a display image 15 of the solar cell module 11 is displayed at a high place such as a Shinkansen, a highland, an airplane, or a distant place. It becomes a huge advertising panel that can be confirmed even from. Therefore, this huge advertising panel contributes as an excellent condition for popularizing and expanding the installation of the photovoltaic power generation system 10. That is, it has both the advertising effect and the solar power generation system diffusion effect.

In the above-described embodiment, the follower 20 is provided with the azimuth angle adjusting mechanism 22 that adjusts the azimuth angle. However, in the present invention, at least the reversing mechanism 23 for turning over (reversing) the solar cell panel 12 is provided. If so, the azimuth adjusting mechanism 22 is not necessarily required.
For example, as shown in FIG. 3, the photovoltaic power generation system 10 of the embodiment is provided with the angle-of-attack adjusting mechanism 21 including the reversing mechanism 23 on a simple base 31. Since other parts are the same as those of the solar power generation system 10 of the embodiment of FIG. An example of the solar cell module 11 in which the plurality of solar cell panels 12 are arranged in a row is as shown in FIG. As for the huge advertising panel, there are the same operations and effects as in the case of FIG.

Although illustration is omitted, it is also possible to provide an information display device that employs “electronic paper” instead of the “cell phosphor layer 14” described above.
Electronic paper is an electronic device that enables display of two or more colors by changing the arrangement of fluids by applying a voltage. The device that applies the voltage is a data rewriting device that rewrites the display (data) on the electronic paper. The data rewriting device is formed so as to be driven by electric energy generated by the solar cell module.

  Electronic paper can rewrite the information displayed by the output from the data rewriting device. That is, if the “cell luminous layer 14” does not form “one pixel” in units of the solar battery cells 13, it is difficult to display typical information, but an information display device that employs “electronic paper” may be used. For example, complex expressions are possible. Further, if the output of the data rewriting device is controlled, the display contents can be changed one after another. Therefore, various displays are possible.

An information display device that employs “electronic paper” can be used to switch to an information display device when, for example, the weather changes from fine weather to cloudy weather and a large amount of power generated by solar power generation cannot be expected.
Note that since electronic paper does not emit light by itself, an illumination device is required to function as a night display device.

  The present invention has applicability in the solar cell manufacturing industry and the advertising industry.

It is a perspective view which shows the information display apparatus which concerns on embodiment of this invention. It is a perspective view which shows the example of the display image at night while showing the solar cell module of the state which arranged the some solar cell panel of FIG. 1 in a line. It is a perspective view which shows the information display apparatus which concerns on other embodiment in this invention. It is a perspective view which shows the example of the display image in the night while showing the solar cell module of the state which arranged the several solar cell panel of FIG. 3 in a line.
