【考案の詳細な説明】
〔産業上の利用分野〕
この考案は太陽電池の支持構造に関し、詳しく
は地表が比較的高い反射率を有する地域、特に冬
季積雪するような地域でも有効に利用出来る太陽
電池の支持構造に関する。[Detailed explanation of the invention] [Industrial application field] This invention relates to a support structure for solar cells, and more specifically, it is a solar cell support structure that can be used effectively even in areas where the ground surface has a relatively high reflectance, especially in areas where there is snowfall in the winter. Related to battery support structure.
太陽エネルギの有効利用の一手段として、太陽
電池の利用が広く知られている。
The use of solar cells is widely known as a means of effectively utilizing solar energy.
この太陽電池を用いた装置においては、効率を
良くするため発電を行う受光面をその地の緯度と
太陽の南中高度とを勘案して、太陽光線に対し直
角に対面するように仰角を調節して設置すること
が重要であり、上記のように太陽光受光面を設置
するには、受光面の地平線に対する傾斜角を、そ
の他の緯度±10°設定することが一般に行われて
いる。 In order to improve the efficiency of this solar cell-based device, the elevation angle of the light-receiving surface that generates electricity is adjusted so that it faces the sun's rays at right angles, taking into account the latitude of the area and the altitude of the sun's meridian. In order to install the solar light receiving surface as described above, it is generally done to set the inclination angle of the light receiving surface with respect to the horizon by ±10° of other latitudes.
ところが太陽電池を設置して発電をしようとす
る場所の地表面が光の反射率の高い地域、あるい
は砂や雪の様に反射率の高いもので、おおわれて
いる場合地表からの反射光量は無視できないが、
従来これらをみすみす損失していることとなる。
However, if the ground surface where you want to install solar cells to generate power is in an area with high light reflectivity, or is covered with highly reflective materials such as sand or snow, the amount of light reflected from the ground surface is ignored. I can't, but
This means that we have been losing out on these things.
さらに上記従来例のような角度に受光面を設定
すると冬季積雪する地域においては受光面上にも
積雪するので受光が不可能となり、また、曇天の
日も多いなどの理由で積雪地においては太陽電池
を用いたエネルギ利用は殆ど実用化されていない
のが現状である。 Furthermore, if the light-receiving surface is set at an angle like the conventional example above, in areas where it snows in the winter, snow will also accumulate on the light-receiving surface, making it impossible to receive light. At present, energy utilization using batteries has hardly been put into practical use.
しかし、融雪、暖房用のエネルギ源として太陽
電池の利用は、かかる積雪地域においてこそ必要
であり、積雪にもかかわらず太陽電池を有効に作
動させ得ることが望まれる。
However, the use of solar cells as an energy source for snow melting and heating is necessary only in such snowy areas, and it is desired that solar cells be able to operate effectively despite snowfall.
さらに海岸の砂地等にでも地表からの反射を有
効に利用することが望まれる。 Furthermore, it is desirable to effectively utilize reflection from the ground surface, such as on sandy beaches.
この考案は上記問題点を解決することを目的と
してなされたものである。 This invention was made for the purpose of solving the above problems.
なお、ここで用いる地表面とは、地表上の堆積
物の表面の意であり、すなわち太陽光にさらされ
る面のことである。 Note that the earth surface used here refers to the surface of deposits on the earth's surface, that is, the surface exposed to sunlight.
即ち、この考案の太陽電池の支持構造は多面体
上下側面を含む外表面全面に受光素子が貼着さ
れ、前記多面体は立設した支柱上端に取付けられ
たことを特徴とするものである。
That is, the solar cell support structure of this invention is characterized in that a light-receiving element is affixed to the entire outer surface of the polyhedron including the upper and lower side surfaces, and the polyhedron is attached to the upper end of an upright support.
周知のように海岸の砂地や積雪表面は白色であ
り、その反射光は曇天下であつてもかなり強い。
As is well known, the sandy and snowy surfaces of the coast are white, and their reflected light is quite strong even on cloudy days.
また曇天下における砂地面や積雪表面の反射光
は散乱光となり、例え北面した垂直面であつても
かなりの入射光量が有る。 In addition, reflected light from sandy or snowy surfaces under cloudy weather becomes scattered light, and even if the surface is vertical and faces north, there is a considerable amount of incident light.
即ち、積雪時の光線の入射方向は雪面からの散
乱光によつて特定せず無指向性の光線と言うこと
が出来る。 That is, the direction of incidence of the light beam during snowfall is not specified by the scattered light from the snow surface, and it can be said that the light beam is non-directional.
従つて、太陽電池の受光素子を多面体の上下側
面を含む表面全面に設け、これを支柱上に高く支
持すれば地表面からの反射光を含め全方向からの
受光が可能となるのである。 Therefore, if the light-receiving element of the solar cell is provided on the entire surface of the polyhedron, including the top and bottom sides, and this is supported high on a support, it becomes possible to receive light from all directions, including light reflected from the ground surface.
さらに重要なことは、積雪地では多面体表面に
は積雪しにくく、しかも太陽電池の受光素子は受
光して発電する際、発熱するので、これが融氷熱
源となることである。 More importantly, in snowy areas, it is difficult for snow to accumulate on the surface of the polyhedron, and the light-receiving elements of solar cells generate heat when they receive light and generate electricity, which serves as a heat source for melting ice.
また、上記の積雪地に限らず海辺の砂浜など地
表よりの光反射が多い地域にも同様のことが言
え、かかる支持構造により直射光及び反射光の両
者を同時に受光可能となり効率化が図られる。 In addition, the same applies not only to the above-mentioned snowy areas but also to areas where there is a lot of light reflection from the ground surface, such as sandy beaches at the seaside, and this support structure makes it possible to receive both direct light and reflected light at the same time, improving efficiency. .
次に、この考案について積雪地の実施例につい
て説明する。
Next, an example of this invention in a snowy area will be described.
第１図はこの考案の実施例の側面図である。 FIG. 1 is a side view of an embodiment of this invention.
直径１ｍのプラスチツク製の球１を用意し、こ
の球１の外表面に３cm×３cmのａ−Si太陽電池２
……２を一面に貼着し、前記球１の下部１Ａに固
定用台座３を設けて第１図に示すように雪面４上
に高さ１ｍとなるよう支柱５上端に固定支持し
た。 A plastic sphere 1 with a diameter of 1 m is prepared, and on the outer surface of this sphere 1, 2 a-Si solar cells of 3 cm x 3 cm are attached.
A fixing base 3 was attached to the lower part 1A of the ball 1 and fixed to the upper end of a support 5 so as to be 1 m above the snow surface 4 as shown in FIG.
上記太陽電池２……２表面の照度を測定したと
ころ、南側半球面で平均50mw／cm2、北側及び下
面半球面でも平均30mw／cm2となり、球面のほぼ
全面で受光されることが判明した。 When we measured the illuminance on the surface of solar cell 2...2, it was found that the average illuminance was 50 mw/cm 2 on the southern hemisphere, and 30 mw/cm 2 on the northern and lower hemisphere, indicating that light was received over almost the entire spherical surface. .
また、球体１上面部の積雪は日出と共に開始す
る発電時の熱により徐々に融解し始め、午前９時
頃には曇天にもかかわらず、すべて融解した。 In addition, the snow on the upper surface of the sphere 1 gradually began to melt due to the heat generated during power generation, which started at sunrise, and by around 9 a.m., it had all melted despite the cloudy weather.
この考案は以上のように構成されているので、
直射、反射光共に万偏なく受光出来、効率が良
い。
This idea is structured as above, so
It can receive both direct and reflected light without any polarization, and is highly efficient.
特に地表面上に光の反射率の高い堆積物の有る
地域、例えば海岸の砂地、コンクリート面、積雪
面等では地表面からの反射光を有効利用でき、さ
らに受光面上の積雪も側面又は下面側での受光発
電の際生じる熱により融解され、流れ落ち、積雪
地でも太陽電池の有効利用が図れるのである。 Particularly in areas where there are deposits with high light reflectance on the ground surface, such as sandy beaches, concrete surfaces, snow-covered surfaces, etc., reflected light from the ground surface can be used effectively, and snow accumulation on the light-receiving surface can also be removed from the side or bottom surface. It is melted by the heat generated during power generation when the light is received on the side, and the solar cells can be used effectively even in snowy areas.
