【従来の技術】
従来の架台を使用した太陽電池アレイの架台を構成する各フレームと各太陽電池モジュール間及び架台自体に防水に関する考慮がされていないという問題点を改良するため、架台を構成する各フレーム間及び各フレームとこれらに接する太陽電池モジュール間の防水性を向上させた屋根一体型太陽電池アレイも開発されたが、アレイを構成する各太陽電池モジュールを支持固定する固定部材の構造が複雑で且つその数も多いため、その製造及びアレイの施工が煩雑になるという問題があった。更に、太陽電池モジュールの温度上昇による発電効率の低下を簡単な構成により、積極的に改善したものは少なかつた。

以下、本発明の実施の形態について説明する。
本発明の屋根一体型太陽電池アレイＳＡは、太陽電池アレイＳＡ自体が屋根瓦の役目を果たし、且つ太陽光により発電を行うもので、太陽電池アレイＳＡを構成する構成部材の部品点数を削減し、且つそれらの構造を簡単な構造にすることにより、その構成部材の製造及び太陽電池アレイＳＡの施工を簡略化し、太陽電池アレイＳＡ内部及び周囲の防水機能を向上させると共に太陽電池モジュール自身の温度上昇を防止するための通風換気機構を有するものである。
【００１４】
そして、本発明の屋根一体型太陽電池アレイＳＡは、平面形状が台形の屋根面（以下、台形屋根面という。）及び平面形状が三角形の屋根面（以下、三角形屋根面という。）からなる屋根面の家屋に適合するもので、平面形状四角形の太陽電池モジュール（以下、四角形太陽電池モジュールという。）ＳＭａ及び平面形状台形の太陽電池モジュール（以下、台形太陽電池モジュールという。）ＳＭｂを複数個縦横に配置することにより、台形屋根面４ａ又は三角形屋根面４ｂに設置が可能となる。この屋根一体型太陽電池アレイＳＡを設置することにより、少なくとも太陽電池アレイＳＡの下面の屋根面には瓦を葺く必要がなくなるので、屋根面の瓦葺き作業が軽減される。
【００１５】
本発明の屋根一体型太陽電池アレイＳＡは、台形屋根面４ａ又は三角形屋根面４ｂに設置されるもので、屋根面縦方向に長尺で太陽電池モジュールの略横寸法の間隔を隔てて屋根面に固定設置される縦樋１と、太陽電池モジュールの左右の側端を固定する部材でＳＭ左側端固定フレーム２２とＳＭ右側端固定フレーム２１とからなる縦フレーム２、太陽電池モジュールの上下端を固定する部材でＳＭ上端固定フレーム３２とＳＭ下端固定フレーム３１とからなる横フレーム３と、屋根面下端部防水機構５と屋根面上端部防水機構６と屋根面右側端部防水機構７と屋根面左側端部防水機構８とからなる太陽電池アレイＳＡと瓦との間の防水を行う防水機構と、通風換気機構９とから構成される。

【００１７】
また、実施例としては示していないが、平面形状四角形（正方形又は長方形）の屋根面の場合は、四角形の太陽電池モジュールＳＭａだけを、屋根面の縦及び横寸法に応じた数を縦横に設置することにより、平面形状四角形（正方形又は長方形）の太陽電池アレイを形成することができる。
【００１８】
本発明の屋根一体型太陽電池アレイＳＡの概略構成を以下に説明する。
本発明の屋根一体型太陽電池アレイＳＡは、図１及び図２に示すように台形屋根面４ａ又は三角形屋根面４ｂに設置されるもので、縦樋１、縦フレーム（モジュールの左右の側端を固定する部材）２、横フレーム（モジュールの上下端を固定する部材）３、屋根面下端部防水機構５、屋根面上端部防水機構６、屋根面右側端部防水機構７、屋根面左側端部防水機構８及び通風換気機構９から構成される。
【００１９】
縦フレーム２は、図１及び図２に示すように、前記台形屋根面４ａ又は三角形屋根面４ｂに設置された複数の四角形太陽電池モジュールＳＭａ及び台形太陽電池モジュールＳＭｂの縦方向１列分の複数のモジュールの左右の側端部を支持固定する部材であり、その形状は長尺で、屋根面縦方向に且つ屋根面に直接設置され屋根面縦方向に長尺の縦樋１の上に沿った状態で一定間隔（モジュールの略横寸法）で設置される。
【００２０】
なお、平面形状三角形及び等脚台形の太陽電池アレイにおいては左右両側端が、平面形状不等脚台形（例えば、一方の脚が垂直の場合）の太陽電池アレイにおいては左又は右の側端が、夫々屋根面に対して斜めに設置されるが、これについても縦フレーム２と定義する。
【００２１】
横フレーム３は、図１及び図２に示すように、前記台形又は三角形の屋根面に設置された複数の四角形太陽電池モジュールＳＭａ及び台形太陽電池モジュールＳＭｂの各モジュールの上下の端部を支持固定する部材であり、その形状は屋根面横方向に長尺で、屋根面横方向に一定間隔（モジュールの略縦寸法）で設置される。
【００２２】
屋根面防水機構は、図１及び図２に示すように、屋根面下端部防水機構５、屋根面上端部防水機構６、屋根面右側端部防水機構７及び屋根面左側端部防水機構８から構成され、これらは夫々屋根面４に設置した太陽電池モジュール群の下端部、上端部及び左右側端部周辺の瓦が葺かれていない部分の防水機能を果たす。
【００２３】
通風換気機構９は、太陽電池モジュールの温度上昇による発電効率の低下を防止する機構で、太陽電池モジュール下面と屋根面との間に隙間を設け、最上部の太陽電池モジュールの上端部を支持固定する横フレーム３、特に、図１２に示すように、ＳＭ上端固定フレーム３２内又は近傍に通風換気機構９を設けることにより、前記隙間を利用して太陽電池モジュール下端部から太陽電池モジュール上端部に向かって、矢印で示す方向に通風することにより、太陽熱等による太陽電池モジュールの温度上昇を防止する。
【００２４】
以下に太陽電池アレイＳＡを構成する各部材の詳細を説明する。

【００２５】
固定部１１は、その断面形状台形の上面がＳＭ左側端固定フレーム２２及びＳＭ右側端固定フレーム２１を固定する部分で、前記台形の２つの斜辺に該当する斜面が縦樋１自体を屋根面４に固定する部分で、これらは夫々釘、ネジ等の固定手段により固定されるものであり、第２雨樋部１３ははＳＭ左端固定フレーム２２のＳＭ左端係合部２２ａと太陽電池モジュールの左端との隙間から漏れた水を下方に流し、同様に第１雨樋部１２はＳＭ右端固定フレーム２１のＳＭ右端係合部２１ａと太陽電池モジュールの左端との隙間から漏れた水を下方に流すもので、第１雨樋部１２及び第２雨樋部１３の側壁は夫々その上端で内側（固定部１１側）に折曲がる折曲部１２ａ及び１３ａを有し、この折曲部１２ａ及び１３ａの上に横フレーム３（ＳＭ上端固定フレーム３２又はＳＭ下端固定フレーム３１）又は太陽電池モジュールＳＭの底面が設置される。
【００２６】
縦フレームカバー１４は、図６、図７及び図９に示すように、固定部１１に固定されたＳＭ左側端固定フレーム２２及びＳＭ右側端固定フレーム２１の上からこれら覆って雨水等の侵入を防止するもので、該縦フレームカバー１４は釘、ネジ等の固定手段により固定部１１に固定される。
【００２７】
縦フレーム２は、図７に示すように、太陽電池モジュールの左又は右側端を固定する部材で、ＳＭ右側端固定フレーム２１及びＳＭ左側端固定フレーム２２から構成される。
【００２８】
なお、平面形状三角形及び等脚台形の太陽電池アレイにおいては左右両側端が、平面形状不等脚台形（例えば、一方の脚が垂直の場合）の太陽電池アレイにおいては左又は右側端が屋根面に対して斜に設置されるが、これについても縦フレーム２と定義する。
【００２９】
ＳＭ右側端固定フレーム２１は太陽電池モジュールの右側端を固定する部材で、屋根面下から見た断面が略「Ｌ」字状の長尺のフレームで、ＳＭ右側端係合部２１ａと縦樋接合部２１ｂとから構成され、ＳＭ右側端係合部２１ａはＳＭ右側端固定フレーム２１の垂直壁の上端部の左方向に略水平に２つの舌片が形成され、これら舌片により太陽電池モジュールの右側端を支持固定するものであり、縦樋接合部２１ｂはＳＭ右側端固定フレーム２１の底辺であり、前記縦樋１の固定部１１の上面と接合し、ネジ又はクギＮ等の固定手段により縦樋１に固定される。
【００３０】
ＳＭ左側端固定フレーム２２は太陽電池モジュールの左側端を固定する部材で、屋根面下から見た断面が略逆「Ｌ」字状の長尺のフレームで、ＳＭ左側端係合部２２ａと縦樋接合部２２ｂとから構成され、ＳＭ左側端係合部２２ａはＳＭ左側端固定フレーム２２の垂直壁の上端部の右方向に略水平に２つの舌片が形成され、これら舌片により太陽電池モジュールの左側端を支持固定するものであり、縦樋接合部２２ｂはＳＭ左側端固定フレーム２２の底辺であり、前記縦樋１の固定部１１の上面と接合し、ネジ又はクギＮ等の固定手段により縦樋１に固定される。
【００３１】
なお、前記ＳＭ右側端固定フレーム２１とＳＭ左側端固定フレーム２２とは互いに断面形状及び寸法が左右対象なものであるので、長さ寸法が同じものであれば上下を反転することにより何れにも使用することができる。
【００３２】
横フレーム３は、図８に示すように、太陽電池モジュールの下端を支持固定するＳＭ下端固定フレーム３１と同じく太陽電池モジュールの上端を支持固定するＳＭ上端固定フレーム３２から構成される。
【００３３】
ＳＭ下端固定フレーム３１は右側面から見た断面が略「Ｌ」字状の長尺のフレームで、ＳＭ下端係合部３１ａと雨樋部３１ｂとＳＭ上端固定フレーム接合部３１ｃとＳＭ上端固定フレーム係合部３１ｄと雪止め部３１ｅとから構成され、その高い側壁の長尺方向の両端部にはＳＭ右端固定フレーム２１又はＳＭ左端固定フレーム２２と固定するためのネジ穴ｎが設けられている。
【００３４】
そのＳＭ下端係合部３１ａは高い側壁の上端部の屋根の高い側の方向に略水平に２つの舌片が形成され、これら舌片により太陽電池モジュールＳＭの下端を支持固定するものであり、雨樋部３１ｂは前記「Ｌ」字状の溝部に形成され、ＳＭ下端係合部３１ａと太陽電池モジュールＳＭの下端との間の隙間から漏れた水を流す雨樋の機能を有し、ＳＭ上端固定フレーム接合部３１ｃは前記高い側壁の上端部のＳＭ下端係合部３１ａとは反対の方向に庇（ひさし）状に延びてＳＭ上端固定フレーム３２のＳＭ下端固定フレーム接合部３２ｄの上面と接合するものであり、ＳＭ上端固定フレーム係合部３１ｄは前記高い側壁の中間位置に設けられ、ＳＭ下端係合部３１ａとは反対の方向に延び且つ下方向に折曲片からなり、ＳＭ上端固定フレーム３２のＳＭ下端固定フレーム係合部３２ｅと係合することにより、ＳＭ下端固定フレーム３１とＳＭ上端固定フレーム３２とが係合するものであり、雪止め部３１ｅは前記ＳＭ上端固定フレーム接合部３１ｃの屋根面の低い側の端部から上側に折曲する折曲片を設けることにより雪止めの機能を有する。
【００３５】
ＳＭ上端固定フレーム３２は右側面から見た断面が逆「Ｌ」字状と「Ｌ」字状のものが背中合わせ状態の略「山」字状の長尺のフレームで、ＳＭ上端係合部３２ａと第１雨樋部３２ｂと第２雨樋部３２ｃとＳＭ下端固定フレーム接合部３２ｄとから構成され、その高い側壁の長尺方向の両端部にはＳＭ右端固定フレーム２１又はＳＭ左端固定フレーム２２と固定するためのネジ穴ｎが設けられている。
【００３６】
ＳＭ上端係合部３２ａは高い側壁の上端部の屋根の低い側の方向に略水平に２つの舌片が形成され、これら舌片により太陽電池モジュールＳＭの上端を支持固定するものであり、第１雨樋部３２ｂは前記逆「Ｌ」字状の溝部に形成され、ＳＭ上端係合部３２ａと太陽電池モジュールＳＭの上端との間の隙間から漏れた水を流す雨樋の機能を有し、第２雨樋部３２ｃは前記「Ｌ」字状の溝部に形成され、ＳＭ下端固定フレーム３１とＳＭ上端固定フレーム３２（ＳＭ上端固定フレーム接合部３１ｃとＳＭ下端固定フレーム接合部３２ｄ）との間の隙間から漏れた水を流す雨樋の機能を有し、ＳＭ下端固定フレーム接合部３２ｄは前記高い側壁の上端部のＳＭ上端係合部３２ａとは反対の方向に庇（ひさし）状に延びてＳＭ下端固定フレーム３１のＳＭ上端固定フレーム接合部３１ｃの下面と接合するものであり、ＳＭ下端固定フレーム係合部３２ｅは前記第２雨樋部３２ｃを形成するＳＭ下端固定フレーム３１側の低い側壁であり、ＳＭ下端固定フレーム３１のＳＭ上端固定フレーム係合部３１ｄと係合することにより、ＳＭ上端固定フレーム３２とＳＭ下端固定フレーム３１とが係合するものである。
【００３７】
縦フレーム２と横フレーム３の接合部、特に、ＳＭ右側端固定フレーム２１及びＳＭ左側端固定フレーム２２とＳＭ下端固定フレーム３１との接合部分について図９を用いて説明する。
【００３８】
図９は屋根面下から上方向を見た図であり、縦樋１の上に固定されたＳＭ右側端固定フレーム２１及びＳＭ左側端固定フレーム２２には夫々太陽電池モジュールＳＭ１及びＳＭ２が支持固定されているが、同様に太陽電池モジュールＳＭ１及びＳＭ２の下端もＳＭ下端固定フレーム３１により支持固定されている。そして、ＳＭ下端固定フレーム３１の底面は縦樋１の第１雨樋部１２の折曲部１２ａ及び縦樋１の第２雨樋部１３の折曲部１３ａの上面に設置されるので、縦樋１とこれと一定間隔隔てて設置された他の縦樋１との間には屋根面とＳＭ下端固定フレーム３１の底面又は太陽電池モジュールＳＭの底面との間に高さＨからなる空間（隙間）が生じ、この空間が通風のために利用される。また、ＳＭ右側端固定フレーム２１と太陽電池モジュールＳＭ１の右側端との隙間、及びＳＭ左側端固定フレーム２２と太陽電池モジュールＳＭ１の左側端との隙間から漏れた雨水等は矢印の方向に流れ夫々縦樋１の第１雨樋部１２及び第２雨樋部１３に流れ落ち、同時にＳＭ下端固定フレーム３１の内側底面を流れる雨水等は矢印の方向に流れ夫々縦樋１の第１雨樋部１２及び第２雨樋部１３に流れ落ちる。
【００３９】
なお、ＳＭ右側端固定フレーム２１及びＳＭ左側端固定フレーム２２とＳＭ上端固定フレーム３２との接合部分については、同様の構成であるから、説明を省略する。
【００４０】
屋根面下端部防水機構５は、図１、図２及び図１０（屋根面右方向から見た図）に示すように、太陽電池アレイＳＡの下端部と屋根面４の下端部間を防水する機構で、耐蝕性の金属板、例えば、フッソ鋼板等からなる防水板５１を屋根面４の下端部に設置する。この防水板５１の縦寸法は屋根面４の下端部に葺いたカラーベスト等の屋根瓦４１から太陽電池アレイＳＡの下端から一定幅（雨が吹き上げた場合に耐えうる距離）までの寸法で、同横寸法は太陽電池アレイＳＡの下端の横寸法と略同じかこれより多少大きめの寸法であることが望ましい。防水板５１の下端部の下面が防水テープ５２により前記屋根瓦４１の上面と固着する。そして、防水板５１の中間部及び上端部に所定間隔で屋根面４にネジ又はクギＮ等で固定すると共に、上端部よりやや下の位置に雨が吹き上げた場合に雨水を阻止する屋根面横方向に長尺で断面形状が「Ｌ」字形の雨止めアングル５３を設置する。この雨止めアングル５３を設置する場合、その底面に防水テープ５３ａを介してネジ又はクギ等で屋根面４に固定する。
