【０００４】
【発明が解決しようとする課題】
従来の屋根材一体型の太陽電池パネル装置は、シール構造を主体とする防水方法が採られている。従って、施工による固定部材間の寸法のバラツキや屋根のうねり等による高低差を吸収できず、また、太陽光や雨水等の外力に対する劣化があり、長期的に安定した防水性を確保できない。また、瓦等の屋根材との調和性に乏しく、屋根材との一体感に欠け、外観性も低いといった問題点もある。
【０００５】
本発明は、係る問題点を解決するためになされたものであって、その課題とするところは、屋根材との調和性があり、屋根材との一体感が備わり、外観性の良い太陽電池パネル装置を提供することであり、寄棟屋根面へ面積効率良く敷設できる太陽電池パネル装置を得ることであり、耐雨水性の高い太陽電池パネル装置を得ること、そして、メンテナンス性の向上を図ることである。
【０００６】
【課題を解決するための手段】
前記課題を達成するために本発明は、傾斜屋根に設置する太陽電池パネルの縦と横の大きさを、屋根材の葺き幅Ｂの方向に枚数ｎの右側屋根材の左端部と左側屋根材の右端部の幅Ａを太陽電池パネルの横幅Ｚとして、屋根傾斜方向の屋根材の葺き足Ｄ、左右の屋根材間の重ね代Ｃ、左右方向の太陽電池パネルの枚数Ｅの関係から、横幅Ｚ＝（Ｂ×ｎ）−Ｃ×Ｅ／Ｅとし、縦幅Ｙを屋根材の葺き足Ｄと同じか、葺き足Ｄの倍数に合わせ、所定の大きさの太陽電池パネルの大きさを設定し、左右の太陽電池パネル間の中央に次段の太陽電池パネルの中央を合わせ、太陽電池パネルの面を階段状に軒側から棟側に設置する手段を採用する。

【０００８】
太陽電池パネル１は、図１〜図３に示すように方形の平盤態に構成された光発電機能体である基盤２の外周縁部に枠状のフレーム３が装着された構成である。基盤２は、充填材層を形成する透明加熱融着材シートにダブ線により電気的に直列接続された複数の太陽電池セルを挟んだものを、表面保護基板と耐候性フィルム等からなる裏面保護材との間に挟持し、その後、真空引きしながら加熱して一体化し、方形の板状に構成されている。フレーム３は、それぞれ表面処理されたアルミ材等により構成され、棟側フレーム４と、軒側フレーム５及び左右の縦フレーム７により方形の枠体に構成されている。
【０００９】
この太陽電池パネル１は、下側（軒側）が開放できる方形の外部枠体８にスライド可能に収め込まれ外部枠体８に一体化されている。この外部枠体８は、太陽電池パネル１の実質的なフレームを構成し、以下に述べる外部枠体８の構成は、スライドにより抜差しできる構成を採らない場合には太陽電池パネル１のフレーム３自体に対して構成される。
【００１０】
この外部枠体８についても表面処理されたアルミ材等により構成され、棟側枠９と左右の縦枠１０と、ネジにより取外し可能に装着された軒側枠１１とにより、方形状に構成されている。棟側枠９には、その前側に太陽電池パネル１の棟側フレーム４を受承する受部と、受部の下側に、受部と一体で幅方向に連続した横水受け樋１２が形成され、後部には、上段の太陽電池パネル１の軒側フレーム５を受承する受部と、受部の下側に、受部と一体で幅方向に連続した横水受け樋１３が形成されている。横水受け樋１２，１３の中央には、垂下状に延びる支持脚部が設けられ、支持脚部の下端に形成された鍵部１４において屋根構造の野地板面１５に棟側枠９がネジによって取付けられる（図９参照）。また、支持脚部には、図１５に示すように開口穴１６が設けられている。
【００１１】
軒側枠１１には、上部にコ字状溝１７が形成され、その下部に軒側に向けて引っ掛け溝１８が形成されている。縦枠１０には、左右の縦フレーム７を受承する受部と、上面に延出する合いじゃくり継ぎにより接合できる平面部１９が形成されている（図１０参照）。縦枠１０の平面部１９の下部には、平面部１９より外側に延出するチャンネル状の受け口２０が形成され、この受け口２０の内側には角筒状の受け口２１が隣設して設けられ、これらの下部には、これらの構造を受ける形態に縦水受け樋２２が一体成形されている。縦水受け樋２２の上端は、棟側枠９より上部に延出していて、棟側枠９の横水受け樋１２の左右端が受けられている。
【００１２】
太陽電池パネル装置は、この外部枠体８と一体化した太陽電池パネル１を屋根構造の野地板面１５上に軒側から棟側に、太陽電池パネル１の上面を階段状に設置して構成される。野地板面１５には防水シート２３が全面に敷詰められ、まず、基準となる軒先部材２４が軒先に取付けられる。軒先部材２４は、野地板面１５端縁を抱込み、野地板面１５上の防水シート２３を潜って野地板面１５上から垂木２５に対してネジ付けされる取付部２６を有し、この取付部２６の軒先側に立上りが付けられた構成である。立上りの上端には棟側に突出する鍵部２７が設けられていて、この鍵部２７に太陽電池パネル１の外部枠体８の軒側枠１１の引っ掛け溝１８を嵌合わせて、軒側枠１１の取付部２６を野地板面１５の垂木２５位置にネジにより固定することにより、軒側の一段目の太陽電池パネル１が敷設される。一段目の左右方向の太陽電池パネル１は、それぞれの外部枠体８の縦枠１０を合いじゃくり継ぎにより接合させて敷設する。
【００１３】
軒先部材２４の取付部２６の野地板面１５より延出する部分には開口穴２８が開けられていて、この開口穴２８を野地板面１５側に傾斜を持って覆う反射板２９が取付けられ、軒側列の太陽電池パネル１の裏面と野地板面１５との隙間は軒側において通風可能な状態になっている。図１４に示すような全体が矩形の太陽電池パネル装置では、軒側の太陽電池パネル１の棟側枠９の受部に次段の太陽電池パネル１の軒側枠１１を受承させて、棟側枠９の鍵部１４を野地板面１５の垂木２５の位置においてネジにより固定する。順次、次段についても同様に敷設して全体として矩形の太陽電池パネル装置が構成される。棟側の外部枠体８の縦水受け樋２２の下端は、その下段の外部枠体８の棟側枠９の上側の横水受け樋１３に受けられている。隣接する横水受け樋１２，１３間の支持脚には、開口穴１６が開けられていて、外部枠体８同士の上下、左右の合わせ部分及び太陽電池パネル１と外部枠体８との隙間から入り込む雨水は、横水受け樋１２，１３と縦水受け樋２２を通じて順次下段に流下し、軒先から屋根に設けられた軒樋に排水される。
【００１４】
千鳥格子状に太陽電池パネルを敷設する太陽電池パネル装置では、図１３に示すように下段の太陽電池パネル１の中央に次段の左右の太陽電池パネル１の合わせ部分が位置するように設置される。この場合、太陽電池パネル１の縦と横の大きさを予め設定しておくことで、屋根材３０との調和性があり、一体感のある太陽電池パネル装置となる。即ち、図４に示すように屋根材３０（和瓦、洋瓦、スレート瓦等）の葺き幅Ｂの方向に枚数ｎの右側屋根材３１の左端部と左側屋根材３２の右端部の幅Ａを太陽電池パネル１の横幅Ｚとして、屋根傾斜方向の屋根材３０の葺き足Ｄ、左右の屋根材３０間の重ね代Ｃ、左右方向の太陽電池パネル１の枚数Ｅの関係から、横幅Ｚ＝（Ｂ×ｎ）−Ｃ×Ｅ／Ｅとする。そして、太陽電池パネル１の縦幅Ｙを、屋根材３０の葺き足Ｄと同じか、葺き足Ｄの倍数に合わせた寸法とする。
【００１５】
この大きさに設定した太陽電池パネル１の左右のものについての間隔Ｆは、例えば、図４のように最も上段（一段目）から二段目の二枚の太陽電池パネル１の全幅が、葺き幅Ｂ×屋根材３０の枚数ｎ×２−屋根材３０間の重ね代Ｃから横幅Ｚに太陽電池パネル１の枚数２を乗じた値を差引いた値となり、太陽電池パネル１の合わせ個所数で除すと、一定の間隔となる。三段目についても、葺き幅Ｂ×屋根材３０の枚数ｎ×３−屋根材３０間の重ね代Ｃから横幅Ｚに太陽電池パネル１の枚数３を乗じた値を差引いた値となり、太陽電池パネル１の合わせ個所数で除すと、一定の間隔となる。つまり、屋根材３０の縦方向の線と横方向の線に揃った整然とした千鳥格子状の太陽電池パネル装置が形成される。また、その間隔Ｆの中間に左右の太陽電池パネル１の合わせ部を設定することができる。
【００１６】
図１４に示すような矩形配列の太陽電池パネル装置についても、図１３に示す千鳥格子状の配列の横方向の太陽電池パネル１の枚数と同様な配列で横方向に設置し、縦方向に直列に所定の段数の太陽電池パネル１を設置することにより構成することができる。
【００１７】
図１３に示すように千鳥格子状に配列した太陽電池パネル装置では、左右に三角形状の階段状部分ができ、最も上段の太陽電池パネル１を除いた階段状部分には隅部水切り部材３３が設けられる。隅部水切り部材３３は、各段の左右端の隅部の雨水を太陽電池パネル１の上面に案内するもので、左右について対称であるため、ここでは右側のものについて説明する。隅部水切り部材３３は、図９に示すように傾斜平面部３４の左側を上側に曲げて延出させた三角形の水返し３５を有する。傾斜平面部３４は、野地板面１５から所定の傾斜をもって太陽電池パネル１の外部枠体８の棟側枠９の上部に先端部が位置し、先端部はコ字状に形成されている。コ字状の先端部には複数の開口穴３６が設けられ、固定用部材３７に引っ掛けられている。傾斜平面部３４の他端には、堰３８が設けられ、堰３８の棟側に延出する平面部において木ネジ等で野地板面１５に固定されている。水返し３５は、外部枠体８の縦枠１０の左右の鍵部３９（最も左右の太陽電池パネルの縦枠１０の場合で右側の場合は右、左側の場合は左に形成されている）内に嵌合するようにされている。
【００１８】
隅部水切り部材３３の右側には、縦にチャンネル状の隅部縦樋４０が設けられている。隅部縦樋４０は、更に下段の太陽電池パネル１の外部枠体８の縦枠１０の鍵部３９に、その立上り部４１が内側において嵌合されている。隅部縦樋４０の右方向には野地板面１５に沿って延びる平面部が形成されていて、屋根材３０の裏側まで延出されその端縁において木ネジ等で野地板面１５に固定され、下段の隅部水切り部材３３の堰３８を越えた位置に下端が配置されている。隅部縦樋４０の平面部には屋根材３０の裏側に潜込む部分に堰４２が立上り部４１に対峙して設けられ、堰４２と立上り部４１との間には屋根材３０の裏面に当て沿うパッキン材４３が介装されている。
【００１９】
固定用部材３７は、下段の太陽電池パネル１の棟側枠９の上部に一端がネジ等で固定され、その端部には凸部４４が曲げ形成されている。凸部４４の頂部には複数の開口穴３６が設けられ、その固定部分の棟側にも複数の開口穴４６が設けられている。この開口穴４６の棟側端から野地板面１５に向かって斜めに案内板４７が設けられ、案内板４７の端縁は太陽電池パネル１の棟側枠９の横水受け樋１３に臨まされている。案内板４７より棟側は、隅部水切り部材３３の傾斜平面部３４の内面に水密状態に接触され、その端部に曲げ形成された立上りにおいて野地板面１５に木ネジ等で固定されている。最も棟側の太陽電池パネル１の棟側には、棟側傾斜水切り部材４８が設けられている。この棟側傾斜水切り部材４８の先端はコ字状に形成され、その端部には複数の開口穴が設けられている。棟側傾斜水切り部材４８も、固定用部材３７に引っ掛けられる傾斜平面部を備え、左右端に野地板面１５に軒側に向けて広がる三角形状部が延出され、隅部縦樋４０の立上り部４１の内側に嵌合されている。隅部縦樋４０は下段の太陽電池パネル１の隅部水切り部材３３の堰３８を越えて下端部が位置される。さらに、棟側傾斜水切り部材４８の棟側縁には堰４９が設けられ、その棟側縁部の平面部において木ネジ等により野地板面１５に固定されている。
【００２０】
このように構成された太陽電池パネル装置は、太陽電池パネル１の縦と横の大きさを、屋根材３０の葺き幅Ｂの方向に枚数ｎの右側屋根材３１の左端部と左側屋根材３２の右端部の幅Ａを太陽電池パネルの横幅Ｚとして、屋根傾斜方向の屋根材３０の葺き足Ｄ、左右の屋根材３０間の重ね代Ｃ、左右方向の太陽電池パネルの枚数Ｅの関係から、Ａ＝Ｂ×ｎ−Ｃ×Ｅに合わせ、幅Ａを枚数Ｅで除した大きさが太陽電池パネル１の横幅Ｚと合致できるようにして、縦幅Ｙを、屋根材３０の葺き足Ｄと同じか、葺き足Ｄの倍数に合わせた寸法としているため、葺き幅Ｂ方向（左右方向）の屋根材３０は、太陽電池パネル１の外部枠体８の左右の縦枠１０の側面に合致する。葺き足Ｄ方向（傾斜方向）の屋根材３０も所定の段数について太陽電池パネル１の各ラインに合致する。
【００２１】
また、左右の太陽電池パネル１の間隔Ｆは、例えば、図４に示すように最も上段（一段目）から二段目の二枚の太陽電池パネル１の全幅がＢ×ｎ×２−Ｃから横幅Ｚに太陽電池パネル１の枚数２を乗じた値を差し引いた値となり、太陽電池パネル１の合わせ個所数で除すと一定の間隔となる。三段目は、全幅がＢ×ｎ×３−Ｃから横幅Ｚに太陽電池パネル１の枚数３を乗じた値を差し引いた値となり、太陽電池パネル１の合わせ個所数で除すと一定の間隔Ｆとなり、屋根材３０の縦のラインに合致する。つまり整然とした千鳥格子状の外観性の良い太陽電池パネル装置となる。左右の屋根材３０と太陽電池パネル１の所定の隙間を確保するためには、葺き幅Ｂを小さい値として幅Ａを設定する。そして、設定時の太陽電池パネル１の枚数Ｅで除して太陽電池パネル１の横幅Ｚを決定する。
【００２２】
この太陽電池パネル装置は、屋根構造の野地板面１５に直に敷設するものであり、その部分の屋根材は不用なため、屋根材３０の使用量も少なくなる。屋根材３０上に降った雨は、屋根材３０を流下して軒樋に流れ込むが、太陽電池パネル装置部においては、屋根材３０上から棟側傾斜水切り部材４８を経て太陽電池パネル１上を流れて軒樋に流れ込む。太陽電池パネル１の左右間に漏水があった場合には、外部枠体８の縦枠１０の受け口２０で受止められ、外部枠体８の最も軒側において、切欠き部（図示しない）から下段の太陽電池パネル１間の上面に流れ落ちる。外部枠体８と縦フレーム７との間に漏水があった場合には、外部枠体８の縦枠１０の受け口２１に受止められ、外部枠体８の最も軒側において、切欠き部（図示しない）から下段の太陽電池パネル１の棟側枠９の上面に流れ落ちる。
【００２３】
外部枠体８の棟側枠９と棟側フレーム４との間に漏水があった場合には、棟側枠９の横水受け樋１２に受止められ、その左右端から縦水受け樋２２に流れ、その下段の縦水受け樋２２へと順次流下して、最終的には軒樋に流れ込む。従って、野地板面１５の防水が長期にわたり確保されることになる。矩形配列の太陽電池パネル装置では、隅部縦樋４０と同様な部材で、棟側傾斜水切り部材４８から軒先までの間を通し、屋根材３０と太陽電池パネル１との間の防水を確保する。この場合には隅部水切り部材３３は使わない。
【００２４】
隅部水切り部材３３への風雨の侵入に関しては、太陽電池パネル１から上昇してくる水については、その多くは固定用部材３７の凸部４４で押し戻され、その一部は開口穴３６に逆昇するが、開口穴４５から案内板４７を伝い、外部枠体８の棟側枠９の横水受け樋１３に受止められる。また、棟側傾斜水切り部材４８の傾斜平面部の雨水が左右方向の風で吹付けられた場合には、外部枠体８の棟側枠９の左右の鍵部３９により水返しされ、軒側に案内されて太陽電池パネル１上に流れる。そして鍵部３９から太陽電池パネル１側へ侵入してくる雨水は、水返し３５により阻止され、軒側に導かれ、太陽電池バネル１の上面に流される。屋根材３０と太陽電池パネル１間の雨水は、隅部縦樋４０へ流れ、隅部水切り部材３３へ流れ、野地板面１５への防水が確保される。
【００２５】
太陽電池パネル装置の裏面の空気は、太陽電池パネル１が太陽光を浴びることにより温度が上昇して軽くなり、開口部から洩れ出す空気の流れができる。この太陽電池パネル装置では軒先部材２４の開口穴２８から空気が導入され、太陽電池パネル１の裏側を上昇して外部枠体８の開口穴１６を通り、一部は固定用部材３７の開口穴４６を通り、隅部水切り部材３３の開口穴３６から大気に放出され、一部は、棟側傾斜水切り部材４８の開口穴から同様にして大気に放出される。残りの空気は、太陽電池パネル装置の左右の縦枠１０との隙間などから大気に放出される。この空気の流れにより太陽電池パネル１が冷却されるとともに、野地板面１５との隙間の換気が行われ、湿度も放出され、樋構造部分等の乾燥が促進される。
【００２６】
太陽電池パネル装置の裏側のメンテナンスは、図１６に示すように外部枠体８の軒側枠１１を外し、枠を開放させて、太陽電池パネル１を外部枠体８から引抜くことで容易に行うことができる。この場合、最も軒側の太陽電池パネル１から、順次外部枠体８から引抜いていくことになる。
【００２７】
【発明の効果】
本発明によれば、屋根材との調和性があり、屋根材との一体感が備わった外観性の良い太陽電池パネル装置が得られる。

The solar cell panel 1 has a configuration in which a frame-shaped frame 3 is mounted on an outer peripheral edge of a base 2 which is a photovoltaic function body formed in a rectangular flat plate shape as shown in FIGS. The base 2 is formed by sandwiching a plurality of solar cells electrically connected in series by a dove wire on a transparent heat-sealing material sheet forming a filler layer, and protecting the back surface comprising a surface protection substrate and a weather-resistant film. It is sandwiched between materials, and then heated and integrated while being evacuated to form a rectangular plate.
