Description

本発明は太陽電池本体の裏面側に光反射部を備えた反射性部材を備えた太陽電池モジュールに関するものである。もしくは本発明は太陽電池本体の裏面側に光反射部と光透過部とを備えた背面部材を備えた太陽電池モジュールに関するものである。   The present invention relates to a solar cell module including a reflective member having a light reflecting portion on the back side of a solar cell body. Or this invention relates to the solar cell module provided with the back member provided with the light reflection part and the light transmission part in the back surface side of the solar cell main body.

近年、地球環境問題、省エネルギーへの関心の高まりとともに、自然エネルギーを利用した新エネルギー技術が注目されている。そのひとつとして、太陽エネルギーを利用したシステムへの関心が高く、とくに太陽光発電装置の住宅への普及が加速されてきている。   In recent years, attention has been paid to new energy technology using natural energy as global environmental problems and energy conservation have increased. As one of them, interest in systems using solar energy is high, and in particular, the spread of solar power generation devices to houses has been accelerated.

太陽光発電装置は、その主要な構成要素である太陽電池モジュールにより太陽光エネルギーを電力に変換して利用することにより、家庭の電気負荷を低減させるものである。   A solar power generation device reduces the electric load of a home | house by converting solar energy into electric power and using it by the solar cell module which is the main component.

住宅においては、家屋の屋根上に太陽電池モジュールを配設して利用されることが多いため、屋根上への太陽電池モジュールの取り付け構造も種々考案されている。   In a house, since a solar cell module is often used on a roof of a house, various structures for mounting the solar cell module on the roof have been devised.

この太陽光発電システムに使用される太陽電池モジュールは住宅屋根に代表される既設の設置面、あるいは地上架台、陸屋根架台等に代表されるような新設された設置面に設置される。   The solar cell module used in this photovoltaic power generation system is installed on an existing installation surface represented by a residential roof, or a newly installed installation surface represented by a ground mount, a flat roof mount, or the like.

それらの設置面に設置するための太陽電池モジュールは、複数の太陽電池素子を直並列に接続し、強化ガラス・封入樹脂・耐候性フィルムで挟持する構造が一般的である。   Solar cell modules for installation on those installation surfaces generally have a structure in which a plurality of solar cell elements are connected in series and sandwiched between tempered glass, encapsulating resin, and a weather resistant film.

図１１は従来の太陽光発電装置に係る太陽電池モジュールの概略断面図である。   FIG. 11 is a schematic cross-sectional view of a solar cell module according to a conventional solar power generation device.

同図に示す太陽電池モジュール４０によれば、１０は太陽電池素子であり、たとえばシリコン等から成る半導体の光電変換効果を利用して電力が得られるように構成したものであって、このような太陽電池素子１０を複数個直列および並列に電気的に接続し、そして、耐候性のある素材で覆うように成し、所要の出力電圧や出力電流を得るようにしている。   According to the solar cell module 40 shown in the figure, reference numeral 10 denotes a solar cell element, which is configured to obtain electric power by utilizing a photoelectric conversion effect of a semiconductor made of, for example, silicon. A plurality of solar cell elements 10 are electrically connected in series and in parallel and covered with a weather-resistant material so as to obtain a required output voltage and output current.

この太陽電池素子１０は単結晶や多結晶シリコンなどの結晶系太陽電池や、薄膜系太陽電池などにより構成する。   This solar cell element 10 is constituted by a crystalline solar cell such as single crystal or polycrystalline silicon, a thin film solar cell, or the like.

かかる太陽電池モジュール４０においては、太陽電池素子１０の受光面にはガラス板や合成樹脂板などの光透過板１１を配置し、その裏面である非受光面にはテフロン（登録商標）フィルムやＰＶＦ（ポリフッ化ビニル）、ＰＥＴ（ポレエチレンテレフタレート）などの耐候性フィルム１２を被着し、光透過板１１と耐候性フィルム１２との間には、たとえばＥＶＡ（エチレン−酢酸ビニル共重合樹脂）などから成る透明な合成樹脂を介在し、充填材１６と成している。   In such a solar cell module 40, a light transmissive plate 11 such as a glass plate or a synthetic resin plate is disposed on the light receiving surface of the solar cell element 10, and a Teflon (registered trademark) film or PVF is disposed on the non-light receiving surface which is the back surface thereof. (Polyvinyl fluoride), PET (Polyethylene terephthalate) or other weather-resistant film 12 is deposited, and between the light transmission plate 11 and the weather-resistant film 12, for example, EVA (ethylene-vinyl acetate copolymer resin) A transparent synthetic resin made of

そして、これら光透過板１１、太陽電池素子１０および耐候性フィルム１２の重ね構造の矩形状の本体に対し、その各辺周囲をアルミニウム金属やＳＵＳ等から成る枠体１５を挟み込むように装着し、太陽電池モジュール４０全体の強度を高めている。   And with respect to the rectangular main body of the stacked structure of the light transmission plate 11, the solar cell element 10 and the weather resistant film 12, the periphery of each side is mounted so as to sandwich the frame body 15 made of aluminum metal, SUS, or the like, The strength of the entire solar cell module 40 is increased.

また、太陽電池モジュール４０の裏面には、すなわち耐候性フィルム１２の上にはＡＢＳ樹脂などの合成樹脂やアルミニウム金属などで構成したジャンクションボックス１３を接着し、太陽電池モジュール４０の出力電力を取り出すターミナルと成している。   Further, a junction box 13 made of synthetic resin such as ABS resin or aluminum metal is bonded to the back surface of the solar cell module 40, that is, on the weather resistant film 12, and a terminal for taking out the output power of the solar cell module 40. It is made.

図１２は従来の住宅の屋根上に太陽電池モジュールを複数載置し、太陽光発電装置とした様子を示す斜視図である。   FIG. 12 is a perspective view showing a state in which a plurality of solar cell modules are placed on the roof of a conventional house to obtain a solar power generation device.

同図に示すごとく、住宅の屋根上に複数の太陽電池モジュール４０を載置した太陽光発電装置３９によれば、太陽電池モジュール４０を複数配設して太陽電池アレイと成し、この太陽電池アレイで発電された電力を送電ケーブル３８および接続３７を通して系統連系インバータ３６へ送電する。   As shown in the figure, according to the solar power generation device 39 in which a plurality of solar cell modules 40 are placed on the roof of a house, a plurality of solar cell modules 40 are arranged to form a solar cell array. The electric power generated by the array is transmitted to the grid interconnection inverter 36 through the transmission cable 38 and the connection 37.

さらに詳しく述べると、通常、送電ケーブル３８の電線は複数本であることが多く、送電ケーブル３８の電線を接続箱３７で並列接続している。そして、太陽電池アレイで発電された直流電力を交流電力に変換する系統連系インバータ３６に入力し、一般の交流負荷に供給したり、もしくは系統連系により電力会社へ売電することができるように構成している。   More specifically, there are usually many electric wires of the power transmission cable 38, and the electric wires of the power transmission cable 38 are connected in parallel by the connection box 37. And it can input into the grid connection inverter 36 which converts the direct current power generated with the solar cell array into alternating current power, can be supplied to a general alternating current load, or can be sold to an electric power company by the grid connection. It is configured.

ところで、太陽電池素子は、光電変換効率の向上を目的として設計されているため、青・濃紺・黒色などの低反射率の色をしていることが多く、前述したような太陽電池モジュール４０を家屋の外から見ると、太陽電池モジュール４０は青・濃紺・黒色の太陽電池素子の色の間を白い線が縦横に走っているように見える。   By the way, since the solar cell element is designed for the purpose of improving the photoelectric conversion efficiency, the solar cell element often has a low reflectance color such as blue, dark blue, and black. When viewed from outside the house, the solar cell module 40 appears to have white lines running vertically and horizontally between the colors of the blue, dark blue, and black solar cell elements.

図１３は従来の住宅の屋根上に載置した太陽電池モジュールの色の見え方を説明する概略断面図である。   FIG. 13 is a schematic cross-sectional view illustrating how the color of a solar cell module placed on the roof of a conventional house is seen.

同図に示すように、太陽電池素子１０の隙間から太陽電池モジュール４０の裏面である非受光面に被着される耐候性フィルム１２が視認でき、しかも、この耐候性フィルム１２が白色などの高い反射率を有する色であり、これにより、太陽電池素子と太陽電池素子外周部や太陽電池素子間において大きな色の差を有し、その結果、視認しやすいものである。   As shown in the figure, the weather resistant film 12 attached to the non-light-receiving surface, which is the back surface of the solar cell module 40, can be visually recognized from the gap between the solar cell elements 10, and the weather resistant film 12 is high in white or the like. This is a color having a reflectance, and thus has a large color difference between the solar cell element and the outer periphery of the solar cell element or between the solar cell elements, and as a result, is easily visible.

前記耐候性フィルム１２については、太陽電池素子外周部や、太陽電池素子間に照射された太陽光を効率よく太陽電池モジュール内部に反射させ、太陽電池モジュールの発電能力を高める効果がある。   About the said weather-resistant film 12, the sunlight irradiated between a solar cell element outer peripheral part and a solar cell element is reflected in a solar cell module efficiently, and there exists an effect which improves the electric power generation capability of a solar cell module.

この効果を高めるためには、耐候性フィルムや太陽電池素子裏面側の封入樹脂を白などの高い反射率を有する色にすることが有効である。   In order to enhance this effect, it is effective to make the weather resistant film or the encapsulating resin on the back side of the solar cell element a color having a high reflectance such as white.

そこで、耐候性フィルムの耐候性を維持したまま、より反射性能が向上するように耐候性フィルムを役割の異なる層を多層に重ね合わせる多層構造とした技術が提案されている（特許文献１参照）。
特開２００２−１００７８８号公報 Thus, a technique has been proposed in which the weather resistant film has a multilayer structure in which layers having different roles are overlapped so as to improve the reflection performance while maintaining the weather resistance of the weather resistant film (see Patent Document 1). .
Japanese Patent Laid-Open No. 2002-100788

しかしながら、前述したように太陽電池素子１０と耐候性フィルム１２との間にて、色の差がある場合、次のような課題があった。   However, as described above, when there is a color difference between the solar cell element 10 and the weather-resistant film 12, there are the following problems.

たとえば、屋根上に設置された太陽電池モジュールを視認すると、高反射率を有する太陽電池素子の外周部や太陽電池素子間が目立ち、青・濃紺・黒の太陽電池素子が暗色系の色によって視覚的に屋根を重厚に見せようとしても、その意図を阻害し、とくに暗系色の屋根材を使用した傾斜屋根面に太陽電池モジュールを設置すると、屋根の一部だけに白色系の線が縦横に走ることとなり、これによって住宅の設置外観を大きく損なっていた。   For example, when a solar cell module installed on a roof is visually recognized, the outer periphery of solar cell elements having high reflectivity and between the solar cell elements are conspicuous, and the blue, dark blue, and black solar cell elements are visually recognized by dark colors. Even if you try to make the roof look heavy, it will hinder your intention, and when you install a solar cell module on a sloped roof that uses dark-colored roofing material, white lines will appear vertically and horizontally on only part of the roof. As a result, the installation appearance of the house was greatly damaged.

一方、このような問題の対策として、外観意匠性を重視し、黒などの低反射率の耐候性フィルムを用いて暗色系の太陽電池素子と太陽電池素子間の耐候性フィルムと極端な明暗の差を生じさせないようにする技術がある。   On the other hand, as a countermeasure for such problems, emphasizing the appearance design, using a weather-resistant film with a low reflectance such as black, the weather-resistant film between the dark-colored solar cell element and the solar cell element and the extreme brightness and darkness There is a technique to prevent the difference.

しかしながら、このような構成によれば、反射光による発電能力向上効果が損なわれ、太陽電池モジュールの発電能力低下を余儀なくされ、その効率低下は５５Ｗの太陽電池モジュールで、およそ５％に達し、太陽光発電として大きな発電損失を生じさせる。   However, according to such a configuration, the effect of improving the power generation capability due to the reflected light is impaired, and the power generation capability of the solar cell module is inevitably decreased. The efficiency decrease is about 5% in the solar cell module of 55 W, and the solar cell module A large power generation loss occurs as a photovoltaic power generation.

また、特許文献１においては、発電効率を向上させるため、機能や効果の異なる層を積層した耐候性フィルムを用いる技術が提案されているが、上述したごとき外観意匠性を改善する方法については記載されていない。   Further, in Patent Document 1, a technique using a weather-resistant film in which layers having different functions and effects are laminated is proposed in order to improve power generation efficiency, but a method for improving the appearance design as described above is described. It has not been.

また、従来の太陽電池モジュールによれば、上述のごとき外観意匠以外に、各太陽電池素子の間に入射する光について、発電効率を高めるための好適な構成が、いまだ十分に検討されていなかった。   Further, according to the conventional solar cell module, in addition to the appearance design as described above, a suitable configuration for increasing the power generation efficiency has not been sufficiently studied for the light incident between the solar cell elements. .

ところで、近年、採光も行なえるようにした住宅用屋根が提案されている。   By the way, in recent years, there has been proposed a roof for a house that can also perform daylighting.

このような住宅用屋根によれば、採光箇所に耐候性フィルムを透光性のものとした透光性太陽電池モジュールを用いて、他方、採光を必要としない箇所に対して前述したような高反射率もしくは着色された耐候性フィルムを用いた構成にしており、このような構成の太陽電池モジュールを配置することで、２種類の太陽電池モジュールを用意しなければならず、これにより、施工が複雑化するという課題があった。   According to such a roof for a house, a light-transmitting solar cell module having a weather-resistant film as a light-transmitting material is used for the daylighting place, and on the other hand, the height as described above for the place not requiring daylighting is used. Two types of solar cell modules have to be prepared by arranging the solar cell module having such a configuration, using a reflectance or colored weather-resistant film. There was a problem of increasing complexity.

したがって本発明の目的は、光反射部を備えた反射性部材を用いることで、各太陽電池素子の間隙に入る太陽光を、さらに発電効率を高めるように有効に利用した太陽電池モジュールを提供することにある。   Accordingly, an object of the present invention is to provide a solar cell module that effectively uses the sunlight entering the gaps between the solar cell elements to further increase the power generation efficiency by using a reflective member having a light reflecting portion. There is.

It is to provide.

The object is to provide a solar cell module.

また、本発明の目的は、設置外観が損なわれることを低減し、意匠性を高めた太陽電池モジュールを提供することにある。   Moreover, the objective of this invention is providing the solar cell module which reduced that the installation external appearance was impaired and improved the designability.

本発明は、光反射部を備えた反射性部材の上に、太陽電池本体を配置した太陽電池モジュールであって、この太陽電池本体は、複数個の太陽電池素子を充填材により封止して成る太陽電池素子群と透光性基板とを備え、隣接する各太陽電池素子の隙間を通して入射した太陽光が、光反射部にて反射し、その反射光が、その隙間を通るように成し、さらに太陽電池本体と、前記反射性部材の間に、前記光反射部の上面を平滑にすべく、透光性樹脂層を形成したことを特徴する。   The present invention is a solar cell module in which a solar cell body is disposed on a reflective member having a light reflecting portion, and the solar cell body is formed by sealing a plurality of solar cell elements with a filler. The solar cell element group and the translucent substrate are configured such that sunlight incident through the gaps between adjacent solar cell elements is reflected by the light reflecting portion, and the reflected light passes through the gaps. Furthermore, a translucent resin layer is formed between the solar cell body and the reflective member so as to smooth the upper surface of the light reflecting portion.

And

また、本発明の太陽電池モジュールは、前記太陽電池モジュールを、壁体に設置するように供したことを特徴とする。   Moreover, the solar cell module of the present invention is characterized in that the solar cell module is provided to be installed on a wall body.

本発明の太陽電池モジュールは、上記構成のごとく、光反射部を備えた反射性部材の上に、太陽電池本体を配置したモジュール構成において、前記太陽電池本体は、複数個の太陽電池素子を充填材により封止して成る太陽電池素子群と透光性基板とを備え、隣接する各太陽電池素子の隙間を通して入射した太陽光が、上記光反射部にて反射し、その反射光が、当該隙間を通るように成し、さらに太陽電池本体と、前記反射性部材の間に、前記光反射部の上面を平滑にすべく、透光性樹脂層を形成したことで、その光反射部の凹凸面に起因して残りやすい残渣や埃、その他の不純物が付着しなくなり、これにより、乱反射が生じにくくなり、光反射部における反射光が隙間を通りやすくなり、その結果、所望どおりの光電変換性能が得られ、発電効率を高めることができる。   As described above, the solar cell module of the present invention is a module configuration in which a solar cell main body is disposed on a reflective member having a light reflecting portion. The solar cell main body is filled with a plurality of solar cell elements. A solar cell element group formed by sealing with a material and a translucent substrate, and sunlight incident through a gap between adjacent solar cell elements is reflected by the light reflecting portion, and the reflected light is A light-transmitting resin layer is formed between the solar cell main body and the reflective member so as to smooth the upper surface of the light reflective portion. Residues, dust, and other impurities that are likely to remain due to uneven surfaces do not adhere, making it difficult for irregular reflection to occur, making it easier for reflected light at the light reflecting portion to pass through the gap, and as a result, photoelectric conversion as desired Performance, It is possible to increase the efficiency.

また、本発明の太陽電池モジュールは、上記構成のごとく、さらに太陽電池本体および反射性部材の双方の縁部を保持する支持体を備えたことで、一体化させ、これにより、隣接する各太陽電池素子の隙間を通して入射した太陽光が、前記光反射部において正確な部位でもって反射し、その結果、所望どおりの光電変換性能が得られ、発電効率を高めることができる。   Moreover, the solar cell module of this invention was integrated by providing the support body which hold | maintains the edge part of both a solar cell main body and a reflective member like the said structure, and, thereby, each adjacent solar The sunlight that has entered through the gap between the battery elements is reflected by an accurate portion in the light reflecting portion, and as a result, the desired photoelectric conversion performance can be obtained and the power generation efficiency can be increased.

For example, it is possible to easily replace a reflective member that has deteriorated and becomes a quality problem. Furthermore, by attaching the reflective member to the support, it is possible to perform excellent daylighting, and it is possible to easily switch to the aim of improving the power generation efficiency by removing it from the support, and as a result, the solar with always high power generation efficiency.

本発明の太陽電池モジュールによれば、その設置に当り、さまざまな仕様が考えられる。たとえば、ビルの屋上において、そのモジュールを水平に設置してもよく、もしくは傾斜屋根上に設置するように供してもよい。   According to the solar cell module of the present invention, various specifications can be considered for the installation. For example, the module may be installed horizontally on the roof of a building, or may be provided to be installed on an inclined roof.

そして、本発明の太陽電池モジュールによれば、前記入射光の入射角度に変動に伴って、その反射光が当該隙間を通るようにすべく、前記光反射部に曲面部を形成した構成にしてもよい。このような構成にしたことで、太陽の移動に伴って、太陽光の入射角度が変わっても、その反射光も各太陽電池素子の隙間を通るようにでき、その結果、大きな光電変換性能が得られ、発電効率を高めることができる。   And according to the solar cell module of the present invention, a curved surface portion is formed in the light reflecting portion so that the reflected light passes through the gap as the incident angle of the incident light varies. Also good. With such a configuration, even if the incident angle of sunlight changes with the movement of the sun, the reflected light can also pass through the gaps between the solar cell elements. As a result, the power generation efficiency can be increased.

また、本発明の太陽電池モジュールによれば、前記光反射部が階段状を成し、この階段上面の太陽光に対する反射率より階段側面の太陽光に対する反射率を低くしたことで、傾斜屋根上に設置した太陽電池モジュールにおいて、人から太陽電池モジュールを見たとき、太陽電池素子と光反射部の階段側面との色の差が目立たなくなり、その結果、反射光による発電能力向上効果を損なうことなく、太陽電池素子と、太陽電池素子外周部や太陽電池素子間の色の差により、住宅の設置外観が損なわれることを低減できる。   Further, according to the solar cell module of the present invention, the light reflecting portion has a staircase shape, and the reflectance with respect to sunlight on the side of the staircase is made lower than the reflectance with respect to sunlight on the top surface of the staircase. In the solar cell module installed on the solar cell module, when the solar cell module is viewed by a person, the color difference between the solar cell element and the staircase side surface of the light reflecting portion becomes inconspicuous, and as a result, the effect of improving the power generation capability by reflected light is impaired. However, it can reduce that the installation external appearance of a housing | casing is impaired by the solar cell element, the solar cell element outer peripheral part, and the color difference between solar cell elements.

さらにまた、隣接する各太陽電池素子の隙間を通して入射した太陽光が、光反射部にて反射し、その反射光が、当該隙間を通るように成したことで、さらに人から見えるのは、階段状の光反射部の各々の間における間隙からなる段差部になり、これにより、太陽光等が強い場合でも、それにより生じる影で段差部となる間隙は一層暗く見える効果を得ることができる。   Furthermore, the sunlight incident through the gaps between the adjacent solar cell elements is reflected by the light reflecting portion, and the reflected light passes through the gaps. Thus, even when sunlight is strong, the gap that becomes the stepped portion can be obtained with the effect of appearing darker.

また、前記光反射部が階段状を成し、この階段上面の太陽光に対する反射率より階段側面の太陽光に対する反射率を低くしたことで、階段状の光反射部の階段側面に照射される散乱光も、この階段側面に吸収され、本発明の効果を一層高めることができる。   In addition, the light reflecting portion has a stepped shape, and the reflectance for sunlight on the side of the staircase is lower than the reflectance for sunlight on the top surface of the staircase, so that the stepped light reflecting portion is irradiated on the side surface of the staircase. Scattered light is also absorbed by the side surfaces of the steps, and the effects of the present invention can be further enhanced.

さらにまた、本発明の太陽電池モジュールにおいては、上記構成のごとく、光反射部と光透過部とを備えた背面部材の上に、太陽電池本体を配置し、そして、この背面部材と太陽電池本体との位置関係を制御して、隣接する各太陽電池素子の隙間を通して入射した太陽光が背面部材の光反射部に投光されるように成したことで、もしくは背面部材の光透過部に投光されるように成したことで、さらに使用上の自由度を高め、たとえば、室内などの採光にも利用することができる。   Furthermore, in the solar cell module of the present invention, as described above, the solar cell main body is disposed on the back member provided with the light reflecting portion and the light transmitting portion, and the back member and the solar cell main body are arranged. The solar light incident through the gap between adjacent solar cell elements is projected onto the light reflecting portion of the back member, or projected onto the light transmitting portion of the back member. By being configured to be illuminated, the degree of freedom in use can be further increased, and for example, it can be used for daylighting in a room or the like.

本発明の太陽電池モジュールにおいては、上記構成のごとく、太陽電池本体および背面部材の双方の縁部を保持する支持体を備えたことで、太陽電池本体および背面部材に対する位置関係を所要通りに設定することができ、設計上の自由度を高めることができる。   In the solar cell module of the present invention, as described above, the positional relationship with respect to the solar cell main body and the back member is set as required by including a support body that holds both edges of the solar cell main body and the back member. It is possible to increase the degree of freedom in design.

たとえば、反射性部材を支持体に対し着脱自在に設けることができる。あるいは、反射性部材を太陽電池本体に対し相対移動すべくスライド構造にもできる。このような構成にしたことで、採光と発電効率向上という切り替えを容易にしている。さらにまた、本発明の太陽電池モジュールよれば、太陽電池モジュールを、壁体に設置するように供することもできる。   For example, the reflective member can be detachably provided on the support. Alternatively, the reflective member can be configured to slide relative to the solar cell body. Such a configuration facilitates switching between lighting and power generation efficiency. Furthermore, according to the solar cell module of the present invention, the solar cell module can be provided to be installed on the wall.

また、本発明によれば、前記のごとく、光反射部を備えた反射性部材や背面部材を構成するに当り、その光反射部を所望する部位、すなわち、太陽電池素子の裏面側の太陽電池素子間および周辺部と対応する部位のみに配置することで、軽量化をはかることができる。   In addition, according to the present invention, as described above, in configuring the reflective member or the back member provided with the light reflecting portion, the portion where the light reflecting portion is desired, that is, the solar cell on the back side of the solar cell element. Weight reduction can be achieved by disposing only between the elements and the part corresponding to the peripheral part.

しかも、本発明によれば、さらに太陽電池本体と反射性部材の各縁部を保持する支持体とを備えたことで、空気層ができ、これによって太陽電池本体に対する断熱性が得られる。しかも、その支持体の構造を規定することで、その空気層の総量を増やし、その結果、断熱性をさらに向上させられる。これにより、家屋の屋根に対し、太陽光による加熱を低減でき、さらには最小限に抑えることができるという効果が得られる。   Moreover, according to the present invention, an air layer is formed by further including the solar cell main body and the support body that holds each edge of the reflective member, and thereby heat insulation with respect to the solar cell main body is obtained. Moreover, by defining the structure of the support, the total amount of the air layer is increased, and as a result, the heat insulation can be further improved. Thereby, the effect that the heating by sunlight can be reduced with respect to the roof of a house, and also it can suppress to the minimum is acquired.

以下、本発明に係る太陽電池モジュールの一実施形態について、模式的に示した図面に基づいて詳細に説明する。   Hereinafter, an embodiment of a solar cell module according to the present invention will be described in detail based on the drawings schematically shown.

（例１）
図１は本発明に係る太陽電池モジュールの一実施形態を模式的に示した側面図（一部断面図）である。 (Example 1)
FIG. 1 is a side view (partially sectional view) schematically showing one embodiment of a solar cell module according to the present invention.

同図に示すように、２０は太陽電池モジュールであり、この太陽電池モジュール２０は太陽電池本体を備える。この太陽電池本体は前記透光性基板である透光性表面部材１と、複数個の太陽電池素子３を透光性充填材２により封止して成る前記太陽電池素子群とから成る。   As shown in the figure, 20 is a solar cell module, and this solar cell module 20 includes a solar cell body. This solar cell body is composed of a translucent surface member 1 which is the translucent substrate and the solar cell element group formed by sealing a plurality of solar cell elements 3 with a translucent filler 2.

具体的には、透光性表面部材１と透光性を有する耐候性フィルム７との間に透光性充填材２を介して太陽電池素子３が挟持される構造となっている。   Specifically, the solar cell element 3 is sandwiched between the translucent surface member 1 and the weatherable film 7 having translucency via the translucent filler 2.

また、太陽電池モジュールの外周には前述の透光性表面部材１などを外部からの衝撃等から保護したり、太陽電池モジュールを固定する役割を持つ枠体１７が取り付けられる。   Further, a frame 17 having a role of protecting the above-described translucent surface member 1 and the like from external impacts and the like and fixing the solar cell module is attached to the outer periphery of the solar cell module.

４は前記反射性部材である反射部材であり、この反射部材４は枠体１７の溝部に嵌り込むようにして取り付けられる。   Reference numeral 4 denotes a reflective member which is the reflective member, and the reflective member 4 is attached so as to be fitted into the groove portion of the frame body 17.

反射部材４はＳＵＳ、鉄やステンレスやアルミニウムのような金属、またはＦＲＰやポリカーボネイトのような耐候性の良い樹脂材から成り、そして、その表面部分（太陽電池モジュール側）に対し、光を高反射率で反射させる鏡面コーティング処理するか、もしくは白色などのような塗装処理をおこなう。さらに表面（受光面側）が図１に示されるような階段形状に成型されている。そして、このような処理でもって前記光反射部を構成する。   The reflecting member 4 is made of SUS, a metal such as iron, stainless steel or aluminum, or a resin material having good weather resistance such as FRP or polycarbonate, and highly reflects light to the surface portion (solar cell module side). Mirror surface coating to reflect at a rate, or paint processing such as white. Furthermore, the surface (light-receiving surface side) is molded into a staircase shape as shown in FIG. And the said light reflection part is comprised by such a process.

次に反射部材４の各部の好適な角度について説明する。   Next, the suitable angle of each part of the reflecting member 4 will be described.

反射部材４は太陽光を反射させて太陽電池素子の発電効率を向上させる面である棟方向面４−Ａ（屋根設置の場合に屋根の棟に平行な面）と、傾斜状態で設置された太陽電池モジュールを地上９から見たときに観測者の目に映る面である軒方向面４−Ｂ（屋根設置の場合に屋根の軒側に向いた面）とから構成される。   The reflecting member 4 is installed in a tilted state with a ridge direction surface 4-A (a surface parallel to the roof ridge in the case of roof installation) that reflects sunlight and improves the power generation efficiency of the solar cell element. The solar cell module is composed of an eave direction surface 4-B (a surface facing the eave side of the roof in the case of roof installation), which is a surface that is seen by the observer when viewing the solar cell module from the ground 9.

そして、太陽電池モジュール２０の非受光面側に前記階段形状を備えた反射部材４を配置するに当り、透光性樹脂層を介して固定する。   And when arrange | positioning the reflective member 4 provided with the said step shape in the non-light-receiving surface side of the solar cell module 20, it fixes through a translucent resin layer.

この透光性樹脂層については、たとえばＥＶＡ（エチレン−酢酸ビニル共重合樹脂）などから成る透明な合成樹脂である透光性封入樹脂層および／またはテフロン（登録商標）フィルムやＰＶＦ（ポリフッ化ビニル）、ＰＥＴ（ポレエチレンテレフタレート）などの透光性耐候性フィルムを用いればよい。   For the light-transmitting resin layer, for example, a light-transmitting encapsulating resin layer and / or a Teflon (registered trademark) film or PVF (polyvinyl fluoride), which is a transparent synthetic resin made of EVA (ethylene-vinyl acetate copolymer resin) or the like. ), PET (polyethylene terephthalate) or the like, a light-transmitting weather resistant film may be used.

太陽電池モジュールの設置角度γは、傾斜屋根の屋根角度と同等になる場合が多く、一方、屋根角度は通常４寸（２１．８度）から６寸（３１．０度）程度の範囲であることが多い。棟方向面４−Ａの設置時の地上面に対する角度αは、地上面から可能な限り棟方向面４−Ａを視認させない角度がよい。観測者が遠方にいる場合を想定すると０度が理想である。また、軒方向面４−Ｂの設置時の地上面に対する角度βは、太陽からの直達光が可能な限り到達しない角度が理想的である。設置面が南向き傾斜面の場合は、設置地点における冬至正午の太陽高度以下であることが望ましい。   The installation angle γ of the solar cell module is often equal to the roof angle of the inclined roof, while the roof angle is usually in the range of about 4 (21.8 degrees) to 6 (31.0 degrees). There are many cases. The angle α with respect to the ground surface when the ridge direction surface 4-A is installed is preferably an angle at which the ridge direction surface 4-A is not visible as much as possible from the ground surface. Assuming that the observer is far away, 0 degree is ideal. Further, the angle β with respect to the ground surface when the eave direction surface 4-B is installed is ideally an angle at which direct light from the sun does not reach as much as possible. If the installation surface is a south-facing inclined surface, it is desirable that the solar altitude is less than the solar altitude at noon in the winter at the installation point.

図２は本発明に係る太陽電池モジュールの太陽光に対する反射状態を説明するための側面図（一部断面図）である。   FIG. 2 is a side view (partially sectional view) for explaining a reflection state of the solar cell module according to the present invention with respect to sunlight.

同図に示すように、太陽光５は太陽電池素子３の表面を照射する以外に、各太陽電池素子３の間から透明の耐候性フィルム７を通り抜けて反射部材４の棟方向面４−Ａ（太陽電池素子３間の隙間の部分）を照射する。   As shown in the figure, the sunlight 5 irradiates the surface of the solar cell element 3, passes through the transparent weather-resistant film 7 from between the solar cell elements 3, and the ridge direction surface 4-A of the reflecting member 4. (A gap portion between the solar cell elements 3) is irradiated.

この場合、棟方向面４−Ａで反射された光が再度、各太陽電池素子３の間を通って透光性表面部材１で再反射し、太陽電池素子３の受光面に照射されて発電に貢献する。   In this case, the light reflected by the ridge direction surface 4-A is again reflected by the translucent surface member 1 through the solar cell elements 3 and irradiated on the light receiving surface of the solar cell elements 3 to generate power. To contribute.

そして、観測者６から太陽電池モジュール２０を視認した場合には軒方向面４−Ｂには太陽光５の直達光が照射されない場合が多く、この場合は軒方向面４−Ｂには散乱光のみが照射され、これにより、地上の観測者６は主に軒方向面４−Ｂのみを視認するので、反射部材４が暗色系の低反射色に見える。   When the observer 6 visually recognizes the solar cell module 20, the eaves direction surface 4-B is often not irradiated with the direct light of the sunlight 5, and in this case, the eaves direction surface 4-B is scattered light. As a result, the observer 6 on the ground mainly sees only the eaves direction plane 4-B, so that the reflecting member 4 appears to be a dark low reflection color.

以上のとおり、反射部材４の光反射面を白色などの反射率を高くした色で製作すると、太陽光５からの入射光の大半は、複数の棟方向面４−Ａに照射され、乱反射されて、その一部は透光性表面部材１や透光性充填材２を通って太陽電池素子３の受光面に照射され、これによって、太陽電池モジュールの発電量が増加するが、本発明者の実験によれば、反射がない場合に比べて約５％の発電量増加が確認され、この反射による発電量増加効果は、従来の太陽電池モジュールにおける白色の耐候性フィルムが平坦に成型されている場合と概略同等である。   As described above, when the light reflecting surface of the reflecting member 4 is manufactured with a color having a high reflectance such as white, most of the incident light from the sunlight 5 is irradiated to the plurality of building direction surfaces 4-A and diffusely reflected. A part of the light is irradiated on the light receiving surface of the solar cell element 3 through the translucent surface member 1 and the translucent filler 2, thereby increasing the power generation amount of the solar cell module. According to the experiment, it was confirmed that the power generation amount increased by about 5% compared to the case where there was no reflection, and the effect of increasing the power generation amount due to this reflection was that the white weather-resistant film in the conventional solar cell module was formed flat. Is roughly equivalent to

かくして詳述したとおり、太陽電池素子３の受光面は低反射色であり、太陽電池素子３間や太陽電池素子３の外周部から見える軒方向面４−Ｂも低反射色に見えるため、観測者６は太陽電池素子３と軒方向面４−Ｂの色の差を認識しがたくなり、その結果、反射光による発電能力向上効果を損なうことなく、太陽電池素子と太陽電池素子外周部や太陽電池素子間の色の差により設置外観が損なわれることを低減できた太陽電池モジュールが得られる。   Thus, as described in detail, the light receiving surface of the solar cell element 3 has a low reflection color, and the eaves direction surface 4-B seen from between the solar cell elements 3 and from the outer periphery of the solar cell element 3 also appears to have a low reflection color. The person 6 becomes difficult to recognize the difference in color between the solar cell element 3 and the eaves direction surface 4-B, and as a result, the solar cell element and the outer periphery of the solar cell element and It is possible to obtain a solar cell module that can reduce the appearance of the installation from being damaged due to the color difference between the solar cell elements.

図１０は本発明に係る反射部材４の他の実施形態を模式的に示した斜視図である。   FIG. 10 is a perspective view schematically showing another embodiment of the reflecting member 4 according to the present invention.

同図に示すように、反射部材４の受光面側（太陽電池モジュール側）を階段状にして、棟方向面４−Ａを白色などの高反射色に着色し、軒方向面４−Ｂを黒色などの低反射色に着色した反射部材４ａとした場合は、軒方向面４−Ｂに照射された散乱光も含めて軒方向面４−Ｂに吸収される率が高くなるため、本考案の効果を一層高めることができる。   As shown in the figure, the light receiving surface side (solar cell module side) of the reflecting member 4 is stepped, the ridge direction surface 4-A is colored in a highly reflective color such as white, and the eave direction surface 4-B is In the case of the reflecting member 4a colored in a low reflection color such as black, the rate of absorption by the eaves direction surface 4-B including the scattered light irradiated to the eaves direction surface 4-B is increased. The effect can be further enhanced.

（例２）
次に太陽電池モジュールと反射部材の組付け構造の例について、図３〜図４を基に説明する。 (Example 2)
Next, an example of the assembly structure of the solar cell module and the reflecting member will be described with reference to FIGS.

本例によれば、太陽電池モジュール２０の非受光面側に空気層を介して反射部材４を配置し、そして、固定する構成である。   According to this example, the reflecting member 4 is disposed on the non-light-receiving surface side of the solar cell module 20 via the air layer and fixed.

具体的には、図３（ｂ）に示すように、太陽電池モジュール２０はその外周にある枠体１７によって屋根上に取り付けられたＳＵＳ、鉄やステンレスやアルミニウム等のレールで構成される架台１８にネジやボルト１９で設置固定される。この時、枠体１７の太陽電池モジュール２０の裏面側に挿入溝２１を設けておけば、図３（ａ）に示すように反射部材４を太陽電池モジュール２０と一体的に取り付けることができる。さらに反射部材４の組付けは太陽電池モジュール２０の架台への設置前でも後でもよく、施工の容易な方を選択することが可能である。   Specifically, as shown in FIG. 3 (b), the solar cell module 20 has a frame 18 composed of SUS, rails of iron, stainless steel, aluminum, or the like attached on the roof by a frame body 17 on the outer periphery thereof. Are fixed with screws and bolts 19. At this time, if the insertion groove 21 is provided on the back surface side of the solar cell module 20 of the frame body 17, the reflecting member 4 can be integrally attached to the solar cell module 20 as shown in FIG. Further, the reflection member 4 may be assembled before or after the solar cell module 20 is installed on the gantry, and it is possible to select the easier construction.

この反射部材４が太陽電池モジュール２０に嵌め込む様子を図４（ａ）〜（ｃ）に示す。同図（ａ）、（ｂ）および（ｃ）の順でもって反射部材４を装着することができる。また、その逆の順序でもって反射部材４を外すことができる。   FIGS. 4A to 4C show how the reflecting member 4 is fitted into the solar cell module 20. FIG. The reflecting member 4 can be mounted in the order of FIGS. 9 (a), (b) and (c). Further, the reflecting member 4 can be removed in the reverse order.

また、このような着脱自在の構造であれば、反射部材４を太陽電池本体に対し相対移動すべくスライド構造になる。   Moreover, if it is such a detachable structure, it will become a slide structure so that the reflection member 4 may move relatively with respect to a solar cell main body.

次に反射部材のその他の構造案について、図５〜図９を基に説明する。   Next, another structure plan of the reflecting member will be described with reference to FIGS.

（例３）
前記反射部材４については、本例のような構成にしてもよい。 (Example 3)
The reflective member 4 may be configured as in this example.

図５に示すように表面の太陽光を反射させて太陽電池素子の発電効率を向上させる面である棟方向面４−Ａと傾軒方向面４−Ｂから成る凸部２２を、板上の基板状に配置した反射部材４１としてもよい。これによって、様々な太陽電池モジュールの大きさに合わせて容易に製造できる構造となる。   As shown in FIG. 5, the convex part 22 which consists of the ridge direction surface 4-A which is the surface which reflects the sunlight of the surface and improves the power generation efficiency of a solar cell element, and the inclined direction surface 4-B is formed on a board. It is good also as the reflection member 41 arrange | positioned at substrate form. Thereby, it becomes a structure which can be easily manufactured according to the size of various solar cell modules.

もしくは図６に示すごとく、一枚の板を凸部２２と凹部２３から成る階段形状に成型または折り曲げた構造にしてもよく、これによって、部材の薄型化による重量の低減化が得られる。   Or as shown in FIG. 6, you may make it the structure which shape | molded or bent one board in the step shape which consists of the convex part 22 and the recessed part 23, and the reduction of the weight by the thickness reduction of a member is obtained by this.

（例４）
また、図７に示すように凸部２２の配置を太陽電池モジュールの太陽電池素子間の隙間部分のみにした反射部材４３とすることにより、余分な凸部を無くして重量軽減となるようにしても良い。 (Example 4)
Moreover, as shown in FIG. 7, by arranging the protrusions 22 to be the reflecting members 43 that are only the gaps between the solar cell elements of the solar cell module, the extra protrusions are eliminated and the weight is reduced. Also good.

さらにまた、図８に示すように凸部２２の表面形状を曲面もしくは多方向へ光が乱反射するように複数の反射面を持つ構成の反射部材４４としてもよい。   Furthermore, as shown in FIG. 8, the convex shape of the convex portion 22 may be a curved surface or a reflective member 44 having a plurality of reflective surfaces so that light is irregularly reflected in multiple directions.

このように入射光の入射角度の変動に伴って、その反射光が各太陽電池素子の隙間を通るようにすべく、凸部２２に曲面部を形成したことで、太陽光の入射角度の変化が生じても透光性表面部材に向けて効果的に反射させることができる。   As the incident angle of the incident light varies in this manner, the curved surface portion is formed on the convex portion 22 so that the reflected light passes through the gaps between the solar cell elements, thereby changing the incident angle of sunlight. Even if this occurs, it can be effectively reflected toward the translucent surface member.

すなわち、このような構成にしたことで、太陽の移動に伴って、太陽光の入射角度が変わっても、その反射光も各太陽電池素子の隙間を通るようにでき、その結果、大きな光電変換性能が得られ、発電効率を高めることができる。   That is, with such a configuration, even if the incident angle of sunlight changes with the movement of the sun, the reflected light can also pass through the gaps between the solar cell elements, resulting in a large photoelectric conversion. Performance can be obtained and power generation efficiency can be increased.

（例５）
また、反射部材を前述した図７のように太陽電池素子間の部分にのみ凸部を配し、かつ反射部材の凹部を光が透過できるように透光性もしくスリットを設けた反射部材４５とし、反射部材４５が可動可能な状態で設置することにより、太陽電池モジュールの発電効率向上と採光を選択可能とすることができる。 (Example 5)
Further, as shown in FIG. 7 described above, the reflecting member 45 is provided with a convex portion only at a portion between the solar cell elements, and the reflecting member 45 is provided with a light transmitting and slit so that light can pass through the concave portion of the reflecting member. In addition, by installing the reflecting member 45 in a movable state, it is possible to select the power generation efficiency improvement and the daylighting of the solar cell module.

具体的には図９（ａ）に示すように太陽電池モジュール２０の枠部１７に、前記背面部材である反射部材４５を取り付けた状態では、太陽電池素子３間を通り抜けた太陽光５は反射部材４５の凸部２２で反射され、透光性表面部材１で再反射して太陽電池素子３の発電に寄与する。   Specifically, as shown in FIG. 9A, in a state where the reflection member 45 that is the back member is attached to the frame portion 17 of the solar cell module 20, the sunlight 5 that has passed between the solar cell elements 3 is reflected. The light is reflected by the convex portion 22 of the member 45, re-reflected by the translucent surface member 1, and contributes to power generation of the solar cell element 3.

一方、反射部材４５の位置を図９（ｂ）のように移動させることによって、各太陽電池素子３の隙間を通り抜けた太陽光５は、反射部材４５の光を透過させる部分である凹部２３を通過し、家屋内への採光が行なわれるようになる。   On the other hand, when the position of the reflecting member 45 is moved as shown in FIG. 9B, the sunlight 5 that has passed through the gaps between the solar cell elements 3 passes through the recesses 23 that transmit light from the reflecting member 45. The light passes through the house and daylighting begins.

このように反射を行なう凸部２２と、光を透過させる凹部２３を使い分けることによって太陽電池モジュール２０を採光用と発電重視型の２つのいずれかを選択できる多機能太陽電池モジュールと成る。   As described above, the solar cell module 20 is a multi-function solar cell module that can select either the daylighting type or the power generation-oriented type by properly using the convex portion 22 that performs reflection and the concave portion 23 that transmits light.

なお、本例では反射部材４５の移動方向を家屋の棟側としたが、上下左右いずれの方向でも良く、また、移動の方法としては手動のほかに電動モーターなどを使って複数の移動を同時に行なえるようにしてもよい。   In this example, the moving direction of the reflecting member 45 is the ridge side of the house. However, the moving direction may be either up, down, left, or right. In addition to manual operation, a plurality of movements may be performed simultaneously using an electric motor or the like. You may be able to do it.

また、とくに図示しないが、太陽電池モジュールの一部を常に採光する部分とした場合、反射部材を用いなければ良いので、太陽電池モジュールを多数配する太陽電池アレイにおいて、透光性を有する太陽電池モジュール（太陽光を背面に通過させる採光型太陽電池モジュール）を通常の太陽電池モジュールと混在して設置する場合に、２種類の太陽電池モジュールを必要とせず、透光性を有する太陽電池モジュールのみを使用し、採光の必要のない場所の太陽電池モジュールに対しては本発明の階段形状に成型または折り曲げた板状の耐候性フィルムを太陽電池モジュールの枠体などに固定して取り付けることにより発電効率を向上させて、太陽光発電装置全体の総発電量を増加させる効果が得られるようにすれば良く、１種類の太陽電池モジュールのみを用いるので施工が簡単で、工場の出荷管理も容易である。   In addition, although not particularly illustrated, when a part of the solar cell module is always a part for daylighting, it is not necessary to use a reflecting member. Therefore, a solar cell having translucency in a solar cell array in which a large number of solar cell modules are arranged. When installing a module (a daylighting solar cell module that allows sunlight to pass through the back) in combination with a normal solar cell module, two types of solar cell modules are not required, and only a solar cell module having translucency. For solar cell modules where lighting is not required, a plate-like weather-resistant film molded or folded into a staircase shape according to the present invention is fixed and attached to the frame of the solar cell module. It is only necessary to improve the efficiency and increase the total amount of power generated by the entire photovoltaic power generation apparatus, so that one type of solar cell can be obtained. Only the construction is simple because using Joule, shipping management of factory is easy.

さらに、図３（ａ）に記したように反射部材４と透光性裏面部材７との間に空気層１４が介在するようになることにより、太陽光で太陽電池モジュール２０が加熱されてもその温度上昇を前記空気層１４と反射部材４及びその背面の空間の３重層で断熱されるので、家屋内への加熱と家屋側からの熱の放出を緩和して家屋内の冷暖房の効率を向上させる。また、このとき、反射部材４と透光性裏面部材７との間の空気層１４に空気の流通ができるようにして太陽電池モジュールの冷却を行い、発電効率の向上ができるようにすると好適である。   Furthermore, even if the solar cell module 20 is heated by sunlight, the air layer 14 is interposed between the reflecting member 4 and the translucent back member 7 as shown in FIG. Since the temperature rise is insulated by the air layer 14, the reflecting member 4 and the triple layer of the space behind it, the heating to the house and the release of the heat from the house side are alleviated to improve the efficiency of the air conditioning in the house.
