Description

The present invention relates to an installation structure of a solar cell panel, and more specifically, a double-sided solar cell panel is vertically installed in a sleeve wall shape so as to protrude perpendicularly to the outer peripheral wall of a building having a wide light receiving surface or the outermost wall of an outdoor wall. In addition, the cover glass of the panel is formed with a convex bulge using ceramics and ink to increase the power generation area in addition to the rooftop, and at the same time improve the design of the building and to the environmental landscape It is related with the installation structure of the solar cell panel which considered consideration.

In recent years, solar power generation has attracted attention as a clean energy source that does not generate pollution such as exhaust gas and radiation from the standpoint of global environmental conservation, and a wide variety of solar cells have been developed, and the price can be reduced by mass production. A wide range of applications has been developed, and the government's environmental policy on housing has been used in buildings and other buildings. As solar power generation is promoted and promoted in this way, its appearance has also become important, and solar power generation systems are installed on buildings with wide light receiving surfaces such as building walls and rooftops. At the same time, in addition to consideration for the landscape environment in addition to power generation, there is an increasing interest in the use of information as a medium for advertising and advertising such as decorative design, letters, and designs.
Since the rooftops of buildings such as buildings and the roofs of houses are empty spaces and are the best parts of 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.
In order to solve the above problems, for example, the following proposals have been made as means for increasing the installation area. Japanese Patent Application Laid-Open No. 2002-076415 and Japanese Patent Application Laid-Open No. 08-162660 propose that the empty space can be used effectively by attaching the solar cell module to one pole in multiple stages. The module shakes due to wind pressure and there is a question about its stability. JP-A 06-318726 and JP-A 06-244445 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 much consideration is not given to the design of the building, the surrounding environment, and the like.

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 inevitably 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 Application 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 a wall surface in accordance with the sun direction. . 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, making the room darker and irritating. Also, 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 planar shape. It is not installed so as to protrude vertically from the wall surface of the building, and it is insufficient in view of 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. Patent Document 6 (WO2005 / 074039) describes a solar power generation device using a solar cell module in which a plurality of solar cell elements are connected and arranged. The invention of the present application is a structure of a double-sided light receiving power generation device. Is different. In the present invention, the two panels are combined into a single double-sided light receiving panel. That is, it is a configuration in which the single-sided light receiving panels on the upper and lower sides are fixed back-to-back with a frame at the joint of the back surface covering material. On the other hand, in patent document 6, it is the structure which assembled the solar cell element group of the single-sided light reception on the upper and lower sides integrally with the filler (EVA) on both sides of the intermediate member. That is, the double-sided light receiving panel is formed as a single panel. Moreover, in patent document 6, there is no description about vertically installing a double-sided light reception type solar cell module in the shape of a sleeve wall so that it protrudes from the outer wall surface of a building at right angles, and the attachment structure to an outer wall surface. Furthermore, in Patent Document 6, a simple double-sided structure is integrally formed with the filler using the upper and lower integral molding, but the restriction of integral molding is unavoidable even with repair replacement. On the other hand, in the double-sided light receiving panel of the present invention, the frame on both sides can be removed and repaired for each side, and if the frame is removed, it can be divided into two pieces and a new frame of appropriate size (thickness) is attached. The conventional single-sided light receiving panel is different in configuration.

Japanese Patent Application Laid-Open No. 2003-166220 discloses an outdoor workpiece in which a double-sided solar panel protrudes from the opposite side of a protective fence road. In other words, a conceptual diagram of an outdoor workpiece with a double-sided solar panel is described, and an outdoor workpiece consisting of a protective fence equipped with a double-sided solar panel is a double-sided solar panel. It is characterized by being. However, although the protective fence provided with the double-sided solar cell panel is illustrated, there is no description about how to install it specifically, its installation method, and installation method as an installation structure.

Problems to be solved by the invention

It is an object of the present invention to provide a solar panel installation structure that can be installed by effectively using unused parts of the outer wall without damaging the design of the building, and that can assist in power generation on the roof. Yes.

Means for solving the problem

The present invention relates to a structure that is three-dimensionally installed so as to protrude perpendicularly from the outer wall surface of a building. Specifically, two single-sided light receiving solar cell panels are processed back-to-back and installed vertically in a sleeve wall shape. The present invention has been completed.
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 coated on one side peripheral surface of the convex portion using colored ceramics and ink, and an optically transparent portion is exposed on the other 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, in the solar cell module described in Japanese Patent No. 3049238, the surface is formed on at least one surface of the convex portion in the convex bulge portion that is formed by ceramic printing and using a screen printing method so as to be approximately uniform and regularly formed as desired. It is the composition of the translucent substrate which provided the coloring layer, and it works to suppress the direct reflected light in combination with the coloring effect of the surface cover glass of the solar cell module, and to the solar cell by irregular reflection with respect to the incidence of sunlight. The light receiving efficiency can be expected to be prevented from decreasing, and the direct reflection of the solar cell module can be expected to be suppressed.

Thus, 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 looks up from the ground. In this case, an effect that the color surface can be emphasized can be obtained. In addition, since rainwater, dust, and the like can be easily removed, the efficiency of electricity transmission does not decrease even during long-term outdoor exposure, and costs can be reduced. As described above, in the present invention, when the surface coloring layer is layered by using the colored ceramic ink on the cover glass in the solar cell module described in Japanese Patent No. 3049238, the solar cell panel of the present invention is attached to the outer peripheral wall. Or, when installed on an outdoor wall, the solar cells are displayed colorfully with anti-reflection of light and color decorations such as letters and pictures that harmonize with the environmental landscape. It works to brighten the environment, provide a display effect, and expand its use as an exterior member.
In addition, the solar cell panel according to the present invention has a ceramic printing convex bulge in the prior patent No. 3482370 proposed by the above-mentioned applicant. There is a description that it is easy to flow dust and the like, but further uses a ceramic ink mixed with tourmaline ore powder particles that form negative static electricity, and exhibits a function of preventing dirt. In the present invention, to prevent the stain on the cover glass on the light-receiving surface, the solar cell is colorfully displayed on the color decoration display by the surface coloring layer using colored ceramics ink, and also has a colorful fashionability. In addition to kneading the tourmaline ore powder, it is possible to prevent contamination of the light-receiving surface by using a mixture of a natural ore powder containing a photocatalytic titanium dioxide or a rare element and a far-infrared ceramic.
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.
In the case of a sleeve-wall-like vertical installation structure, a plurality of installations may be provided on the entire side wall having no opening, or between the opening and the opening, and the size and position of the opening. And a well-balanced installation location of solar panels can create a building with a rich expression. Outside scenery can be seen from the indoor side, and since it is not attached to the upper part like a kite, it does not interfere with daylighting and functions as a blindfold or partition for privacy protection.
Light that hits the light-receiving surface passes through the 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, light is not easily absorbed, and low-reflection glass is used. Even if it is a solar panel, there is no perfect absorption, and the flat light installed on the roof only dissipates the reflected light. On the other hand, by vertically installing a plurality of sets of double-sided light receiving panels according to 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.
In addition, in the structure of the present invention that is installed vertically on the outer wall of the building in the form of a sleeve wall, the double-sided light-receiving solar cell of the present invention and, for example, the light-receiving surfaces of two single-sided light-receiving solar cell panels are arranged outside, The fashionability of a building can be further improved by combining and arranging triangular bay window solar cell panels that are assembled and installed in a triangular bay window.
In general, it is known that the performance of a semiconductor element decreases with increasing humidity, and it is said that the conversion efficiency of a non-crystalline optical semiconductor element solar cell is reduced by about 0.25% per 1 ° C. temperature increase. . Therefore, how to keep the temperature rise of the panel low and prevent the conversion efficiency from falling is one of the important issues. In the double-sided light-receiving solar cell panel of the present invention, a gap is provided between the wall surface and the solar cell panel formed between the two panels, and when installed on the outer wall surface of the building, the panel body is bolted to the housing. It is installed and mounted on the outer wall surface using installation fittings such as nuts, and the presence of the gap space works to suppress the temperature rise.
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 glass surface is ceramic-printed, the attached dust is easily washed away, thus preventing a decrease in power generation efficiency. be able to. The larger the size of the panel that can be installed, the larger the light-receiving area. The direction is preferably 300 to 600 mm, and the length, that is, the longitudinal direction corresponds to the floor height, for example, 2500 to 3000 m. In addition, the thickness is about 100 mm in the case of a double-sided light-receiving panel in which single-sided light-receiving solar cell panels are back to back.
For installation in a new building, anchor bolts, nuts, washers, etc. provided on the long side of the solar panel are joined to the anchor bolts fixed to the horizontal bars of the frame and fixed to the wall surface. That's fine.
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 bracket.
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.

The invention's effect

According to the solar cell panel installation structure of the present invention, by attaching a plurality of sets to the outer wall of the building in the form of a sleeve wall, the amount of power generation per building can be significantly increased in addition to the array of roofs. In addition, the function of the configuration in which the convex bulge is formed on the cover glass using ceramic ink can be exhibited. In addition, if the installation location is designed by the architect's original idea, the fashionability of the building can be improved.

In addition, when the solar cell panel of the present invention is installed on the outer wall surface of a building or the like, the solar cell is displayed in a colorful manner by color decoration display such as anti-reflection of light and characters, picture patterns etc. in harmony with the environmental landscape. Together with the original power generation of the solar cell, the design display can brighten the environment and add a display effect, so that the use as an exterior member can be expanded.
Furthermore, when the solar cell panel according to the present invention is installed on a wall surface or roof, the cover glass is formed with a ceramic printing convex bulge, so that dirt accumulation due to conditions of outdoor exposure for a long period of time can easily flow. In addition, the surface coloring layer is coated with colored ceramics and ink on one peripheral surface of the convex part, and the light transmission property remains on the exposed part of the other peripheral surface. In addition, the layering of the surface coloring layer makes the solar cells look colorful with colored decoration displays such as letters and pictures that harmonize with the environmental landscape, and this advertising decoration design display brightens the environment together with the original power generation of the solar cells. , It can amplify the display effect and work to expand its use.

However, the present invention is not limited to these examples. In the present invention, the structure provided with the ceramic printing convex bulging portion is that the outer peripheral wall of the building or the outermost wall of the outdoor wall has a wide light receiving surface. In the implementation area, the two-sided light receiving panel of the present invention removes both frames and replaces and repairs each side depending on the circumstances that require restrictions or restrictions on advertising or color decoration display due to consideration of the environmental landscape, etc. In addition, if the frame is removed, it is divided into two pieces, so that a ceramic / ink convex bulge can be formed only on one side. Further, when a frame having an appropriate dimension (thickness) is newly attached, a normal single-sided light receiving panel can be obtained.
