【発明の属する技術分野】
本発明は、平板状の太陽電池モジュールを複数連結し、展開と収納が容易な可搬型太陽電池パネルに関する。
【０００２】
【従来の技術】
現在、エネルギー資源の確保と環境保護の立場からクリーンなエネルギーの研究開発が進められており、中でも太陽電池はその資源（太陽光）が無限であること、無公害であることから注目を浴びている。太陽電池の中でも、ひとつの基板上にプラズマＣＶＤ装置などで形成される薄膜太陽電池は、薄型で軽量、製造コストの安さ、大面積化が容易であることなどから今後の太陽電池の主流になると考えられる。
近年、この薄膜太陽電池を使用した平板状の太陽電池モジュールとして、薄膜太陽電池をガラス板、接着封止材、バックシートで積層封止して一体的に封止形成したスーパーストレート型太陽電池モジュール、および、薄膜太陽電池の表面（受光面）および裏面（受光面の反対側面）を保護材と接着封止材で封止し、裏面側に補強板を取り付けたサブストレート型太陽電池モジュールが作られており、一般住宅をはじめ、工場などの産業用、公共施設への適用展開が図られているのと同時に、災害時の緊急用小型電源として応用することなどが考えられている。
【０００３】
図９は平板状の太陽電池モジュールの１例の概要を示す断面図である。
太陽電池１０１は、その受光面である表面およびその反対側の裏面の両面を保護材と接着封止材を兼ねる保護層１０２で封止されており、太陽電池１０１の裏面の両側縁には電力を端子部３０まで導く内部リード線１０４（１０５）が設けられている。また、太陽電池１０１の非発電面側（裏側）には、補強板１０６が取り付けられている。太陽電池モジュールの構造はこれに限られるものではなく、保護層と接着封止材とが別である場合もある。
このような平板状の太陽電池モジュールが複数連結されてなる太陽電池パネルを展開収納する方式としては、折り畳む方式あるいはスライド方式の２つの方式があり、例えば、特許文献1や特許文献２に開示されている。
【０００４】
折り畳む方式は、太陽電池モジュール端部に櫛歯状のヒンジナックルを設けて隣接する太陽電池モジュールの櫛歯状のヒンジナックルと噛み合わせ、ヒンジナックルを貫通する可撓性ピントルで蝶番を形成して折り畳む方式である。折り畳んだ収納状態のとき、太陽電池モジュールは互いに同じ面が向かい合う。
スライド方式は太陽電池モジュールを互いにスライドさせて展開収納する方式である。収納状態のとき、太陽電池モジュールは互いに同じ面が向かい合う。
図１０は従来の折り畳む方式の太陽電池パネルの例を示す平面図であり、図１１は図１０におけるＡＡ断面図である。図１２は従来の太陽電池パネル（図１０、１１）を折り畳みかけた時の概略斜視図である。
【０００５】
太陽電池４０１は、表裏面を保護材と接着封止材である保護層４０２で封止されており、太陽電池４０１の両側面には電力を端子ボックス４０３まで導く内部リード線４０４、４０５が設けられている。また一点鎖線で示した折り曲げ位置４０６を避けて太陽電池４０１の非発電面側（裏側）には、金属板などから構成される補強板４０７が設けられている。各太陽電池モジュールは展開時あるいは収納時にはレール４０８に沿って移動される。

【特許文献２】
特開２００２−２６３５７号広報（第４−５頁、第１０、１４、1５図）
【０００７】
【発明が解決しようとする課題】
上記のようなパネルは元来建造物や広い場所に恒久的に設置されることを目的としているため、パネル自体にレールや枠が組み込まれており、可搬型に必要な取り扱いの容易さや軽量性などは考慮されていなかった。
本発明の目的は、展開や収納が容易で、また収納状態での搬送も容易な可搬型の太陽電池パネルを提供することである。
【０００８】
【課題を解決するための手段】
前述の目的を達成するために、太陽電池を挟んで表面（受光面）には保護層が裏面には補強板が一体化され、また電力を外部に取り出す端子部を有し、端子部間には端子部間配線がされた平板状の太陽電池モジュール（以下、太陽電池モジュール）が複数連結されてなり、太陽電池モジュールは展開時には平面状並列配置され、収納時には重ね合わされる可搬型太陽電池パネルにおいて、前記太陽電池モジュールの同じ側の両角部（下両角部という）に太陽電池モジュールのスライドを補助するガイドを設け、そのガイド隙間に他の太陽電池モジュールの板厚方向側面を挟み込む構造であり、展開時には複数枚の太陽電池モジュールが連結されほぼ平面状になり、収納時には全ての太陽電池モジュールは重ねあわされた形態であることとする。
【０００９】
前記太陽電池モジュールのスライドを補助するガイドの材質は滑り性の良い４フッ化エチレン樹脂、ポリテトラフルオロエチレン樹脂、またはこれらの樹脂を表面にコ−ティングした金属材料であると良い。
前記太陽電池モジュールの前記ガイドの反対側の辺の両角部（上両角部という）には前記ガイドに引っ掛かる大きさの突起を設けると良い。
前記端子部を、太陽電池モジュール受光側の下両角部に配置すると良い。
前記端子部間配線は太陽電池モジュールの側面方向外部空所に各々配置されると良い。
【００１０】
前記端子部間配線の形状を、コイル状とし収納時にコンパクトにまとめられると良い。
収納時に外側となる太陽電池モジュールの裏面に固定バンドを取り付けてあると良い。連結させた複数枚の太陽電池モジュールの先頭にあたる太陽電池モジュールの上側中央部と最後尾にあたる太陽電池モジュールの下側中央部に、太陽電池モジュール同士の伸縮を容易にするための取っ手を設けると良い。
【００１１】
【発明の実施の形態】
以下、実施例に従い本発明を詳細に説明する。
実施例１
このような太陽電池モジュールを複数枚連結した可搬型太陽電池パネルを展開し、受光しての発電している状態を以下にいくつか示す。
図１は本発明に係る可搬型太陽電池パネルを展開している状態の斜視図である。図２は本発明に係る可搬型太陽電池パネルを構成する１枚の太陽電池モジュールの斜視図である。図３は本発明に係る可搬型太陽電池パネルを展開している状態のガイド部の斜視図である。図４はガイド部を太陽電池モジュール板厚方向から見た側面図である。図５は本発明に係る折畳まれた状態の可搬型太陽電池パネルの斜視図である。図６は折畳まれた状態の可搬型太陽電池パネルの端子やガイドのある付近を示す斜視図である。
【００１２】
ガイド２０は太陽電池モジュール１０の下両角部１４に位置し、コの字型の形状をしており、太陽電池モジュール１０の受光面１６の下両角部１４にガイド２０の接続面２１を接触させながら、太陽電池モジュール１０の横端面１７とガイド２０の内側面２３との間にわずかなガイド隙間２４をあけ接着またはネジなどにより装着される。更にガイド２０には太陽電池モジュール１０の板厚よりわずかに大きいスライド隙間２２を設け、連結される他の太陽電池モジュール１０を挟み込む機能を有する。更にガイド２０の伸縮方向幅は後述される端子部３０の伸縮方向幅と同じかそれ以下の幅とする。更にガイド２０は他の太陽電池モジュール１０をスライドし易くさせるため滑り性の良い四フッ化エチレン樹脂、ポリテトラフルオロエチレン樹脂、または前述樹脂を表面にコーティングした金属材料を使用するのが望ましい。このようなガイドと突出の組み合わせにより、複数枚の重ね合わせた太陽電池モジュールが連結され展開する際に抜け落ち単独となることはない。
【００１３】
突出片１５は、太陽電池モジュール１０の上両角部１３に位置し太陽電池モジュール１０の横端面１７から太陽電池モジュール１０を発電使用時方向にスライドさせた時に重なり合う他の太陽電池モジュール１０上に装着したガイド２０に引っ掛かる程度の突出長さで横方向に突出しており太陽電池モジュール１０に加工形成される。
これらのガイド２０と突出片１５を設けることにより、複数枚の太陽電池モジュール１０各々を端子部３０から突出片１５の間でスライドさせることが可能となる。また、収縮時（収納時）には各々の太陽電池モジュール１０に設けられたガイド２０どうしがストッパとなり太陽電池モジュール１０が抜け落ち単独となることを防止でき、発電使用時には各々の太陽電池モジュール１０に設けられたガイド２０と突出片１５がストッパとなり太陽電池モジュール１０が抜け落ち単独となることを防止できる。
【００１４】
端子部３０は、複数枚の連結された太陽電池モジュール１０が収縮方向（収納方向）にスライドし重ね合わされた時に重ね合わせを阻害しない、受光面１６側の下辺１８と太陽電池下辺１９の間上で下両角部１４付近に設けられ接着またはネジなどにより装着される。この端子部３０を設けることにより、太陽電池モジュール１０で発電された電力を外部に導くことが可能となる。
端子部間配線４０は、各々の太陽電池モジュール１０に設けられた端子部３０間を電気的に接続するものであり、展開時には、端子部３０から太陽電池モジュール１０の横端面１７方向に向かってから、太陽電池モジュール１０の横端面１７付近に沿ってから次の端子部３０に逆の形状で接続され、浅いＵの字型の形状となり、端子部間配線４０の長さは複数枚の太陽電池モジュール１０が発電使用時方向にスライドした展開時には引っ張らない程度の長さとする。そのため複数枚の連結した太陽電池モジュールがスライドし収縮した時に各々の太陽電池モジュールの重ね合わせを阻害することはない。
【００１５】
この端子部３０と端子部間配線４０を設けることにより各々の太陽電池モジュール１０で発電した電力を図示しないインバータに導くことが可能となる。
取っ手５０は、複数枚の連結された太陽電池モジュール１０の先頭に位置する先頭太陽電池モジュール１１と最後尾に位置する最後尾太陽電池モジュール１２のスライド方向中央に配置しネジなどの機械的な接続により取り付けられる。
この取っ手５０を設けることにより、複数枚の連結された太陽電池モジュール１０のスライドを容易に行うことができるようになる。
実施例２
図７は本発明に係る他の太陽電池パネルの展開している状態の斜視図である。図８は本発明に係る他の太陽電池パネルの収縮方向に重ね合わせた時のガイド部斜視図である。
【００１６】
この例では既に、図１、３、５、６に示した端子部間配線４０の変形例として配線の端末部以外がコイル状に形成された端子部間コイル状配線４１を用いた。端子部間コイル状配線４１は、各々の太陽電池モジュール１０に設けられた端子部３０間を電気的に接続するものであり、展開時には、端子部３０から太陽電池モジュール１０の下辺１８に沿って、横端面１７に向かう直線状の端末部に続いて太陽電池モジュール１０の横端面１７付近に沿ってから次の端子部３０に逆の形状で接続される。端子部間コイル状配線４１の形状は配線の端末部以外がコイル状に形成されており、複数枚の太陽電池モジュール１０が発電使用のためにスライド展開した時に滑らかに追従して伸びるものである。
【００１７】
端子部間コイル状配線４１は、端子部３０から太陽電池モジュール１０の横端面１７方向に向かって接続され形状は配線の端末部以外がコイル状に形成されているため、収縮方向（収納方向）にスライドされ重ね合わされた時でもコイル状部が収縮し無駄な収納スペースが不要となる。複数枚の連結した太陽電池モジュールがスライド収縮した時に各々の太陽電池モジュールの重ね合わせを阻害しない。
この端子部３０と端子部間コイル状配線４１を用いた場合においても、各々の太陽電池モジュール１０で発電した電力を図示しないインバータに導くことが可能となる。
【００１８】
取っ手５０は、複数枚の連結された太陽電池モジュール１０の先頭に位置する先頭太陽電池モジュール１１と最後尾に位置する最後尾太陽電池モジュール１２のスライド方向中央に配置しネジなどの機械的な接続により取り付けられる。
この取っ手５０を設けることにより、複数枚の連結された太陽電池モジュール１０のスライドが伸縮時に容易にできるようになると同時に、複数枚の太陽電池モジュールを重ね合わせ収納し搬送するときの搬送用取っ手にも使用される。
固定バンド５１は、複数枚の連結された太陽電池モジュール１０の先頭に位置する先頭太陽電池モジュール１１のスライド方向に配置しネジやリベットなどの機械的な接続により複数個取り付けられる。
【００１９】
この固定バンド５１を設けることにより、図６に示すような複数枚の太陽電池モジュールを重ね合せた収納時に重ね合わせた収納形態が保持でき、太陽電池モジュールの搬送が容易になる。
【００２０】
【発明の効果】
本発明によれば、太陽電池を挟んで表面（受光面）には保護層が裏面には補強板が一体化され、また電力を外部に取り出す端子部を有し、端子部間には端子部間配線がされた平板状の太陽電池モジュールが複数連結されてなり、太陽電池モジュールは展開時には平面状並列配置され、収納時には重ね合わされる可搬型太陽電池パネルにおいて、前記太陽電池モジュールの同じ側の両角部（下両角部という）に太陽電池モジュールのスライドを補助するガイドを設け、そのガイド隙間に他の太陽電池モジュールの板厚方向側面を挟み込む構造であり、展開時には複数枚の太陽電池モジュールが連結されほぼ平面状になり、収納時には全ての太陽電池モジュールは重ねあわされた形態としたため、レールがなくとも、太陽電池パネルの展開収納は容易にできるようになる。
【００２１】
叉、複数枚の太陽電池モジュールを各々ガイドで連結し伸縮可能にしたことにより、例えば、災害時などの緊急用小型電源などとして使用する場合、搬送時においては太陽電池モジュールをスライドさせ収縮し重ね合わせ搬送時形態を小さくすることが可能であり、限られた車両等の収納スペースに対し太陽電池モジュールを多数積載でき効率的であり搬送に掛かる費用も安価となる。また、現地において太陽電池モジュールを発電使用する時には、発電使用方向にスライドさせ太陽電池モジュールを伸ばすことで発電を行うことが可能となる。また、太陽電池モジュールの端子部を繋ぐ端子間配線が常設されているため、現地での配線接続作業が少なく容易に設置でき太陽電池モジュール設置作業費用も安価となる。

[0002]
[Prior art]
Currently, research and development of clean energy is being promoted from the standpoint of securing energy resources and protecting the environment. Above all, solar cells are attracting attention because of their infinite resources (sunlight) and no pollution. Yes. Among solar cells, thin-film solar cells formed on a single substrate using a plasma CVD device, etc. will become the mainstream of future solar cells because they are thin and lightweight, inexpensive to manufacture, and easy to increase in area.

[Problems to be solved by the invention]
The above panels are originally intended to be permanently installed in buildings and large areas, so rails and frames are built into the panels themselves, making them easy to handle and light in weight. Etc. were not considered.
An object of the present invention is to provide a portable solar cell panel that can be easily deployed and stored and can be easily transported in a stored state.
[0008]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, a protective layer is integrated on the front surface (light-receiving surface) with a solar cell in between, and a reinforcing plate is integrated on the back surface. Is composed of a plurality of planar solar cell modules (hereinafter referred to as solar cell modules) with wiring between terminals, and the solar cell modules are arranged in parallel in a planar shape when deployed, and are stacked when stored. In the solar cell module, a guide for assisting the slide of the solar cell module is provided at both corners (referred to as lower corners) on the same side of the solar cell module, and the thickness direction side surfaces of the other solar cell modules are sandwiched between the guide gaps When deployed, a plurality of solar cell modules are connected to form a substantially flat shape, and all the solar cell modules are stacked when stored.
[0009]

[0016]
In this example, as a modification of the inter-terminal wiring 40 shown in FIGS. 1, 3, 5, and 6, the inter-terminal coil wiring 41 formed in a coil shape other than the terminal portion of the wiring is used. The inter-terminal coiled wiring 41 electrically connects the terminal portions 30 provided in each solar cell module 10, and extends from the terminal portion 30 along the lower side 18 of the solar cell module 10 when deployed. Then, following the linear terminal portion toward the lateral end surface 17, the solar cell module 10 is connected to the next terminal portion 30 in the opposite shape after being along the vicinity of the lateral end surface 17 of the solar cell module 10. The terminal-to-terminal coiled wiring 41 is formed in a coil shape except for the terminal part of the wiring, and smoothly follows and extends when a plurality of solar cell modules 10 are slid and deployed for power generation use. .
[0017]
The inter-terminal coiled wiring 41 is connected from the terminal 30 toward the lateral end surface 17 of the solar cell module 10 and the shape is formed in a coil shape except for the terminal portion of the wiring. Even when they are slid and overlapped, the coil-shaped portion contracts, so that useless storage space becomes unnecessary. When a plurality of connected solar cell modules are slid and contracted, the overlapping of the solar cell modules is not hindered.
Even when this terminal portion 30 and the coil wiring 41 between the terminal portions are used, it is possible to guide the power generated by each solar cell module 10 to an inverter (not shown).
