Description

The present invention relates to an installation structure of a solar cell panel to which a light source is attached. Specifically, the installation area is increased in order to increase the amount of power generation in the daytime, and an advertisement can be displayed at night, and the design of the building It is related with the installation structure of the solar cell panel which improves performance.

Photovoltaic power generation has become increasingly popular these days when the use of renewable energy is promoted. Developed a wide variety of solar cells, and, price reduction by mass production also made progress in a wide range of applications, has come to Ru is also widely used in environmental policy is also building I phase俟on housing of the government.
Since the roofs of houses and the rooftops of buildings are empty spaces with the best sunlight, the installation locations are concentrated here. However, there is a need for an elevator machine room and staircase on the rooftop of the building, and in some cases, an air conditioner outdoor unit, etc. Recently, the rooftop is used to prevent the heat island phenomenon or raise awareness of coexistence with the natural environment. Many buildings have gardens, biotopes, vegetable gardens, etc., and their usage area is limited. Even if you want to occupy as wide a range as possible, the installation location of solar panels is usually limited.
As means for enlarging the installation area, Japanese Patent Application Laid-Open No. 2002-076415 and Japanese Patent Application Laid-Open No. 08-162660 propose that an empty space can be used effectively by attaching a solar cell module to a single pole in multiple stages. However, there are doubts about the stability of a plurality of strip-shaped modules that shake under the wind pressure. JP-A 06-318726 and JP-A 06-44445 also propose installation on the outer wall as well as the roof.
However, in these inventions, attention is paid only to efficient light receiving means, and little consideration is given to the design of the building or the building, the surrounding environment, and the like.

Prior patent documents

Patent Document 1 (Japanese Patent Application Laid-Open No. 2008-111322) discloses a decorative decorative plate to be attached to a wall surface, on which a dye-sensitized solar cell having a visible light transmittance of 20% or more is provided. Therefore, it is proposed that the text on the decorative plate can be seen through the solar cell. Although it is an invention pursuing the design of the solar cell panel itself, the installation to the wall surface is flat, so that the installation area is not greatly earned. Patent Document 2 (Japanese Patent Laid-Open No. 10-018467) proposes an integrated panel of a sound insulating material and a solar cell that does not impair the installation landscape. The appearance of a huge building with solar cells facing the outside of the noise barrier on the highway is a strange sight with a blackish tone, and has no design. Patent Document 3 (Japanese Patent Application Laid-Open No. 09-021117) proposes to heal the monotonousness of the driver by projecting the picture provided in the tunnel with the electric power obtained from the solar cell panel integrated with the sound insulation wall of the highway. However, the light receiving surface is still poor in design. Patent Document 4 (Japanese Patent Application Laid-Open No. 2002-010494) proposes attachment to a bridge girder, a fence, a side wall, a concrete pillar, or the like of an expressway. Although the idea of effective use of a vast space is excellent, it is attached to the side wall in a flat shape, and the design as a building is low as described above. Patent Document 5 (Japanese Patent Laid-Open No. 2005-223164) describes a double-sided light receiving solar cell, which is proposed to be capable of efficient power generation if it is installed vertically on the wall surface in accordance with the sun direction. Yes. However, the backside of the double-sided solar cell of Patent Document 5, that is, the transparent efficiency on the transparent backsheet side will be inferior to that on the front side, particularly when using a thin-film silicon solar cell. There is no choice but to use polycrystalline silicon molds, and these are dark and opaque, which makes the room dark and unpleasant. The single crystal or polycrystalline silicon type is more expensive than the thin film silicon type, and it is extremely uneconomical when many panels are arranged in parallel. Furthermore, it is described that when the installation angle is set to 60 degrees in the double-sided light receiving solar cell of Patent Document 5, an electric energy of 120 degrees can be obtained compared to the single-sided light receiving type, In comparison, it is natural that a system with a backside power function on the back side will increase the annual power generation. Further, in the vertical installation method, the building is characterized in that it is perpendicular to the ground surface as a fence-integrated or handrail-integrated shape mainly on the roof of the building, and the plurality of panels are arranged in a plane. It is not enough to install it so as to protrude vertically from the wall surface of the building, and it is insufficient in view of the effective use of the installation area. The same applies to the installation on the side walls, piers, etc. of the expressway, and there is no change to planar light reception.

An object of the present invention is to provide an installation structure of a solar cell panel with a light source capable of expanding the installation area of the solar cell panel and capable of advertising at night.

It has been found that by arranging a light source on one end of the solar cell panel in the longitudinal direction, it is possible to advertise it that can display characters such as company names and logos and designs and designs at night. It was.
Specifically, two single-sided solar cell panels are back-to-back via a transparent substrate, and in some cases, a light-reflective layer is provided between the two, and is fixed by being sandwiched between frames and processed into a double-sided light-receiving solar cell panel . On one end surface of the frame of the panel in the longitudinal direction, an installation bracket and a lighting fixture for attaching to the wall surface of the building are arranged, and the opposite side longitudinal end surface exposes the long side end of the transparent substrate. If you install multiple sets on the unused part such as outer wall and rooftop outer periphery parapet, etc., you can increase the power generation area in the daytime and it is effective for auxiliary power generation of rooftop solar panel, At night, it can be used as a panel with a display that can display neon sign-like light by emitting light from a lighting fixture.
The solar cell panel according to the present invention has a convex bulge by a screen printing method using the ceramic ink described in the prior patents 32867777, 3482370 and 30409238 proposed by the applicant. It is desirable to use a solar cell module of the formed translucent substrate.
Among them, in the solar cell module described in Japanese Patent No. 3049238, a surface coloring layer is layered on one side of the convex portion using colored ceramic ink, and light is transmitted to the exposed portion of the other one side peripheral surface. For example, when the non-printing part with light transmission and the printing part of the coloring layer are arranged vertically, the power generation by light reception from above and when looking up from below It is intended to provide a solar panel installation structure that has a variety of fashionability.
In addition, the solar cell module described in Japanese Patent No. 3049238 uses at least one surface of the convex portion of the convex bulge portion, which is formed by ceramic printing ink, and is formed in a substantially uniform and regular manner by a screen printing method. The structure of a translucent substrate provided with a surface coloring layer on the surface, and in combination with the coloring effect of the surface cover glass of the solar cell module, works to suppress the direct reflected light, and the solar cell by irregular reflection with respect to the incidence of sunlight The structure can be expected to prevent the light receiving efficiency from being reduced to the cell and to suppress direct reflection of the solar cell module.
Therefore, in the solar cell installation structure according to the present invention, in the configuration in which color printing is performed on the half surface of the convex bulging portion of the surface cover glass, in the case of wall surface installation in the present invention, the observer comes to look up from the ground. In this case, the color surface can be emphasized. In addition, since it is easy to remove rainwater, dust, etc., the efficiency of electricity transmission does not decrease even when exposed outdoors for a long period of time, and the cost can be reduced. Thus, in the present invention, the solar cell module described in Japanese Patent No. 3049238 In the case where the surface coloring layer is layered using colored ceramics and ink on the cover glass, when the solar cell panel of the present invention is installed on the outer wall or the roof outer peripheral parapet, etc., the characters that prevent reflection of light and harmonize with the environmental landscape , show the colorful solar cell color decoration display, such as a picture pattern, together with the solar cells original發電by this ad decorative design display, brighten the environment, exhibit the display effect, demonstrate the spread of the use of as an exterior member To work.
Furthermore, in the present invention, when the surface coloring layer is applied to the cover glass of the solar cell module described in Japanese Patent No. 3049238 by using colored ceramics and ink, the solar cell panel of the present invention is installed on the wall surface or the roof. When displaying the solar cell, it is displayed in a colorful manner with anti-reflection of light and color decorations such as letters and pictures that harmonize with the environmental landscape, and this advertisement decoration design display makes the environment brighter together with the original power generation of the solar cell. Another display effect can be added, and the use as an exterior member expands.
Further, the solar cell panel according to the present invention is also provided in the prior patent No. 3482370 proposed by the above-mentioned applicant. Although it is easy to flow, there is a description that the anti-smudge function is exhibited using ceramic ink kneaded with tourmaline ore particles that form negative static electricity. Furthermore, in the present invention, in order to prevent the stain on the cover glass on the light receiving surface in order to make the solar cell look colorful with colored decoration display by the surface coloring layer using colored ceramics and ink, and also to have rich fashionability. In addition to kneading the above-mentioned tourmaline ore particles, the photocatalytic titanium dioxide-containing or natural ore powder containing rare elements and a mixture of far-infrared ceramics can be used to prevent contamination of the light-receiving surface.
However, a double-sided light-receiving solar cell described in Patent Document 5, a single crystal silicon type, a polycrystalline silicon type, or a thin film silicon type solar cell can also be used. Among these, an inexpensive thin-film silicon mold is preferable because of the advantage that the module size can be freely changed.
The transparent substrate sandwiched between the single-sided light-receiving solar cell panels is preferably a white plate glass or an acrylic plate having a thickness of 3 to 5 mm, and ordinary blue plate glass is not preferable.
Depending on the material of the transparent substrate, the light emitted from the light source may diffuse and be transmitted and absorbed by the back surface coating material side. In order to prevent this, an aluminum foil or an aluminum vapor deposition film is sandwiched as a light reflecting material. The light source that emits light at night whose thickness is preferably 10 to 15 microns is not particularly limited, but an LED lighting apparatus that consumes at least a long life is desirable. Light bulbs and fluorescent lamps are becoming popular, and a plurality of LEDs may be inserted into a dedicated socket holder that can be set on a mounting frame, and then inserted.
In the case of a sleeve-wall-like vertical installation structure, it is desirable that the part be easily accessible to the night, and a plurality of parapets on the building roof or on the entire side wall having no opening may be installed, or between the openings. It is possible to create a building with a rich expression in the daytime by setting the size of the opening and its location and the location of the solar panel in a well-balanced manner, and as an advertising panel at night Works effectively.
Whether it is daytime or nighttime, it is possible to see the outside scenery from the indoor side, and it is not attached to the top like a kite, so it does not interfere with daylighting, and it is also useful as a blindfold or partition for privacy protection It is.
Light that hits the light-receiving surface passes through the cover glass on the surface and is absorbed by the solar cell element.However, when the solar altitude is low in the morning and evening, that is, when the incident angle is large, the light is not easily absorbed, and a low-reflection cover glass is used. Even if it is the used solar cell panel, there is no complete absorption. In the flat type installed on the roof, the reflected light is merely dissipated. On the other hand, by vertically installing a plurality of sets of double-sided light receiving panels of the present invention, it becomes possible to receive reflected light from adjacent panels for power generation, and as a result, the power generation efficiency per set of panels is improved. .
In addition, although the power generation efficiency on the wall surface is lower than that on the rooftop, it can be compensated by increasing the number of installations, making it possible to reduce costs by taking advantage of the scale advantage. At dusk, it can block the sun and suppress the temperature rise in the room.
The type that is attached to the sloped roof of a detached house, the flat type that is installed on the roof of a building, etc. are easily affected by pollutants due to rainfall, and the reduction in power generation efficiency due to dirt is regarded as a problem. For example, Japanese Patent Application Publication No. 2009-164434 has proposed that the shape of the frame is devised so that water does not stay. Japanese Patent Laid-Open No. 10-290020 proposes means for decomposing adhering contaminants with a photocatalyst. According to the present invention, since it is installed in the vertical direction, it is less likely to receive rainfall directly, and since the cover glass surface is ceramic-printed, the adhering dust is easily washed away, reducing the power generation efficiency. Can be prevented.
The larger the size of the panel that can be installed, the larger the light receiving area, but there is a limit to the mounting strength, and in consideration of the pressure and the external appearance of the building when looking at the outside from the inside, the width, that is, It is desirable that the short piece direction is 300 to 600 mm, and the length, that is, the longitudinal direction corresponds to the floor height, for example, 2500 to 3000 mm . Further, the thickness is 100 mm or less, preferably 20 to 30 mm in the case of a double-sided light-receiving solar cell panel in which single-sided light-receiving panels are processed back to back with a transparent substrate interposed therebetween.
For installation in a new building, it is only necessary to fix the bolts, nuts, washers, etc. provided on the long side of the solar panel through the plate to the anchor bolts fixed to the horizontal bars of the frame, and fix them to the wall surface. . In addition, when a continuous balcony around the outer wall is provided for each floor height, it is more stable if the lower end of the solar cell panel is installed on the balcony in addition to the joining by the installation fitting.
In the case of retrofitting by renewal, a chemical anchor is fixed after drilling in the housing structure, and the installation bracket of the solar cell panel may be fixed thereto.

According to the installation structure of the solar cell panel with a light source according to the present invention, by arranging a plurality of sets on the outer wall or parapet of the building, the power generation amount per building is greatly increased in addition to the array of the roof portion. In addition, it is possible to improve the corporate image and the fashionability of the building by incorporating the design and installation location into a design as a display that can display advertisements at night.
Furthermore, when the solar cell panel with a light source according to the present invention is installed on the wall surface or the roof, the cover glass is formed with a ceramic printing convex bulge, so that dirt such as dust easily flows and acts on the antifouling property. In addition, in the configuration in which the surface coloring layer is layered using colored ceramics and ink on one week surface of the convex portion, and the light transmittance remains on the exposed portion of the other one circumferential surface, antireflection of light, and With the surface coloring layering, the solar cells are displayed colorfully with color decorations such as letters and pictures that harmonize with the environmental landscape, and this advertisement decoration design display makes the environment brighter together with the original power generation of the solar cells. Another display effect can be added and amplified, and it works to expand its use.
