Abstract
Description
すなわち、特許文献2に記載の集光型太陽発電装置では、入射する光の光軸を確認するための装置が取り付けられている。
本発明の実施形態の要旨としては、少なくとも以下に列記するものが含まれる。
この場合、上から落ちてくる塵埃、水滴、異物、その他通気孔には入れたくない物を、庇部によって排除することができる。
この場合、付着した塵埃が滑り落ち易くなるので、塵埃が、庇部の上面に堆積しにくい。
この場合、庇部が、通気孔を外側正面から全部隠す(但し、下方に隙間はある。)ことにならない。従って、庇部による塵埃等の排除と、通気孔の良好な通気性とを、両立させることができる。
このように、筐体の側壁に通気孔が設けられる構成により、筐体の上面または底面に通気孔が設けられる構成に比べて、雨水、水滴または虫などの異物の侵入を効果的に抑制することができる。さらに、異物侵入抑制部が設けられていることにより、空気の出入りを確保しながら異物の侵入をより確実に抑制することができる。従って、より優れた太陽光発電モジュールを提供することができる。
このように、異物が筐体の側壁とフレーム部材との隙間を経由しない限り筐体内へ侵入しない構成であることにより、異物の侵入を一層抑制することができる。また、筐体の側壁とフレーム部材との隙間を異物侵入抑制部として利用することにより、新たな部材を別途用いることなく異物の侵入を抑制することができるため、低コストを実現することができる。
このように、筐体のフランジがフレーム部材に接触することにより、筐体の側壁とフレーム部材との隙間の一部がフランジにより塞がれ、異物の侵入経路がさらに制限されるため、異物の侵入を一層抑制することができる。
このような構成により、複数の太陽光発電モジュールを連結させる際、嵌合部を目視しながら施工を行うことができるため、連結作業を行いやすい。また、フランジに嵌合部を設けることにより、嵌合のための構造を比較的容易に作製することができる。
このような構成により、複数の太陽光発電モジュールをフレーム部材に固定するための作業を効率良く行うことができる。
この構成によれば、集光する太陽光が発電素子から外れた場合に、遮蔽板によって、側壁の内面や、通気孔に設けられるフィルタの焼損を防止することができる。
また、樹脂製の側壁を有する太陽光発電モジュールであっても、パネル筐体への装着により、十分な機械的強度を発揮する。
以下、本発明の実施の形態について図面を用いて説明する。便宜上、説明したいポイントに沿って、第1部、第2部に分けて説明する。
第2部は、主として、上述の(1)~(4)、(12)に関連する。
但し、第1部の構成、及び、第2部の構成は、相互に任意に組み合わせることができる。
[太陽光発電装置の構成]
図1は、第1の実施の形態に係る太陽光発電装置の外観を示す斜視図である。また、図2は、図1に示す架台の構成を示す斜視図である。
図3は、第1の実施の形態に係る太陽光発電モジュールの外観を示す斜視図である。また、図4は、第1の実施の形態に係る太陽光発電モジュールの平面図である。
このように、筐体21の側壁24に通気孔24hが設けられる構成により、筐体21内の温度を気温に近づけ、過度な温度上昇を抑制することができる。
なお、筐体21全体で少なくとも2つの通気孔があれば、空気の入口と出口がある状態となるので好ましい。但し、筐体21全体で通気孔が1つであっても、筐体21内が密閉した空間になることは避けられ、筐体内と外気との圧力バランスを保つことができる。また、通気孔の開口面積や形状を工夫することで最低限の通気性は確保することができる。
図7は、図5に示す通気孔の拡大図である。
第2の実施の形態に係る太陽光発電モジュール1は、他の太陽光発電モジュール1の筐体21と嵌合可能な構成を含む。ここでは、上述した第1の実施の形態に係る太陽光発電モジュール1と異なる点について主に説明する。
[付記1]
発電素子と、
前記発電素子が収容される筐体とを備え、
前記筐体の側壁には通気孔が形成され、
さらに、
前記通気孔を介した前記筐体の内部空間への異物侵入を抑制する異物侵入抑制部を備え、
前記筐体の上面にはフレネルレンズが設けられ、前記筐体の底面には前記発電素子が設けられ、
前記筐体の前記側壁は樹脂により形成され、前記通気孔は、射出成型により前記筐体の前記側壁と一体成型される、太陽光発電モジュール。
発電素子と、
前記発電素子が収容される筐体とを備える太陽光発電モジュールであって、
前記筐体は、他の前記太陽光発電モジュールの前記筐体と嵌合可能な嵌合部を含み、
前記筐体の上面にはフレネルレンズが設けられ、前記筐体の底面には前記発電素子が設けられ、
前記筐体の前記側壁は樹脂により形成され、前記嵌合部は、射出成型により前記筐体の前記側壁と一体成型される、太陽光発電モジュール。
すなわち、第1部と同様に、太陽光発電モジュール1は、光を受けて発電する発電素子30と、発電素子30を収容する閉鎖された筐体21とを備えている。筐体21は、太陽光を集光するレンズ(フレネルレンズ22f)が設けられた集光部22、発電素子30が配置される底部23、および、底部23の外枠を成し、集光部30を支持する側壁24を有する。
図13において、この庇部60は、通気孔24hの上から側壁24の外側へ張り出す張り出し部60aと、張り出した先端側から、通気孔24hの外側に沿って下へ垂れる垂下部60bとを有する形状である。
図14において、この庇部60は、通気孔24hの上から側壁24の外側へ張り出し、かつ、通気孔24hの外側で下へ垂れる滑らかに連続した形状である。
このような庇部60の形態は、図13の形態よりもさらに、付着した塵埃が滑り落ち易くなるので、塵埃等が、庇部の上面に堆積しにくいという利点がある。
通気孔24hに格子部24gを設ける点は、図15と同様であり、格子部24gは同様の作用効果を奏する。当該第5例が、図15の第4例と異なるのは、庇部60が、通気孔24hの上側の一部を隠す形状である点である。言い換えれば、庇部60は、通気孔24hを外側正面から全部隠す(但し、下方に隙間はある。)ことにならない。従って、庇部60による塵埃等の排除と、通気孔24hの良好な通気性とを、両立させることができる。
追尾機構2dは、方位角及び仰角の2軸に駆動可能な機構を有し、制御盤2cに設けられた制御部(図示せず。)の制御によって、常に、太陽を追尾するように制御される。
なお、第1部、第2部のそれぞれにおいて、開示された実施の形態(実施例)はすべての点で例示であって制限的なものではないと考えられるべきである。本発明の範囲は特許請求の範囲によって示され、特許請求の範囲と均等の意味及び範囲内での全ての変更が含まれることが意図される。
