【０００１】
【発明の属する技術分野】
本発明は、太陽電池モジュールの取付け施工方法に関する。
【０００２】
【従来の技術】
近年のＣＯ2 の増加による地球温暖化現象の問題は深刻な状況にあり、又今後世界的にエネルギー消費量が予想されるなか資源の枯渇化が重大な問題となっている。そこで、ＣＯ2 を排出せず、資源の制約や環境負荷の少ない太陽光エネルギーは重要な位置を占めるものである。この太陽光エネルギーを電気に変換する太陽電池モジュールが現在注目されている。この太陽電池モジュール３は、図６に示すようにフレームレスモジュール３１の周縁部を、アルミニウムからなる枠体３０で嵌め込み、その枠体３０同志を連結してなっている。このフレームレスモジュール３１は、多数個の太陽電池セル３２をインターコネクタ等により直列又は並列に接続した太陽電池セル列を、透明樹脂からなる充填材を介在させて、白板強化ガラス板と耐候性フィルムとで挟み込んだ構造であって、白板強化ガラス板が受光面となっている。
【０００３】
この太陽電池モジュールを瓦棒を有する屋根に取り付ける従来例の施工方法を、図７及び図８に従って説明する。図７は平面図を示し、図８は図７のＡ−Ａ’断面図を示すものである。各図に示すように、先ず屋根の瓦棒６に屋根上取付具１を据え付ける。この屋根上取付具１は、図５に示す斜視図のようになっている。その屋根上取付具１上面の偏平部に２つのアングル材を合わせてなる取付部材３０を取り付け、それに太陽電池モジュール３の枠体３０を取り付けるものであった。
【０００４】
しかしながら、この取付部材３０は高さが５０ｍｍ程度あり、建築限界間際に施工された建築物の屋根に設置する際には、この高さが問題になることがあり、又２つのアングル材を合わせなければならないため、手間がかかり、経済性についても問題がある。
【０００５】
【発明が解決しようとする課題】
そこで上記の問題を解決するため、高さが低く、経済性についても有利で、更に屋根への取り付けを容易なようにした太陽電池モジュールの取付け施工方法を提供することにある。
【０００６】
本発明によれば、瓦棒を有する屋根に太陽電池モジュールを取り付ける施工方法であって、瓦棒の上面を偏平に確保するための屋根上取付具を瓦棒に嵌め込むように取り付け、横辺と、横辺の両側から横辺に対して垂直にのびる縦辺とによって形成された開口部を有し、断面がコ形状の長尺部材からなるモジュール取付具を準備し、モジュール取付具を長尺方向が瓦棒に直交するように配置し、このモジュール取付具をコ形状の開口部が上になるようにして屋根上取付具に取り付け、ケーブルを配線するためのスペースが、縦辺と、太陽電池モジュールの枠体とによって、開口部に設けられるように、モジュール取付具の横辺に太陽電池モジュールの枠体を取り付けることを特徴としている。
【０００７】
好ましくは、断面がＬ形状の固定具の一辺を前記モジュール取付具の横辺に固定し、その他辺を太陽電池モジュールの枠体に固定することにより、モジュール取付具に太陽電池モジュールの枠体を取り付けてもよい。
【０００８】
【発明の実施の形態】
以下、本発明の詳細を図面に基づいて説明する。
【０００９】
図１及び図２は、本発明の第１実施例を示すものであって、図１は平面図を示し、図２は図１のＡ−Ａ’断面図を示す。先ず瓦棒６を有する屋根に屋根上取付具１を瓦棒６に嵌め込むようにして取り付ける。この屋根上取付具１は、瓦棒６の上面形状が丸型であったり尖端が尖っている場合があるため、上面形状を偏平に確保するものであって、図５に示すように屋根上取付具１の上面が偏平形状となっている。この屋根上取付具１は、高さが８５ｍｍ、長さが１４０ｍｍ程度のステンレス製からなっており、瓦棒６の長さ方向に５０ｃｍ程度のピッチで設置する。そして、断面がコ形状の長尺なモジュール取付具２を準備する。このモジュール取付具２はコ形状の開口部２０を上にして用いるものである。その状態における、モジュール取付具２の横辺２１の幅が１７０ｍｍ、両側の縦辺２２の高さが２０ｍｍ程度となっており、これもステンレス製からなっている。そして、このモジュール取付具２の長さ方向が、瓦棒６の直角方向になるように配置し、各瓦棒６に設置された屋根上取付具１にボルト２Ａで固定する。その後、モジュール取付具２の開口部２０に、太陽電池モジュール３の枠体３０を位置させる。その際、１つのモジュール取付具２には２つの太陽電池モジュール３の枠体３０の一辺及び他辺が配置されている。そして、断面がＬ形状の固定具４を準備し、その縦辺４０を太陽電池モジュール３の枠体３０に、横辺４１をモジュール取付具２の開口部２０にボルト２Ｂ，３Ａで固定する。その結果、瓦棒６、屋根上取付具１、モジュール取付具２及び太陽電池モジュール３が一体化し、屋根に太陽電池モジュール３を取り付けることができるようになっている。そして、このモジュール取付具２の開口部２０は、ケーブルを配線するのに適した形状となっている。それは、モジュール取付具２に備えられた両側の縦辺２２が壁の役目をして、ケーブルの大きな位置ずれを防ぐことができるようになっている。
【００１０】
図３及び図４は、本発明の第２実施例を示すものであって、図３は平面図を示し、図４は図３のＡ−Ａ’断面図を示す。以下、第２実施例について説明するが、上記した第１実施例と同様の構成からなるものは説明を省略する。上記の第１実施例と相違する点は、太陽電池モジュール３の枠体３０の裏面に接着剤５を塗布し、その接着剤５で枠体３０をモジュール取付具２の開口部２０に接着する。好ましくは、枠体３０の裏面に数個のスペーサー（厚さ５ｍｍ、幅及び長さ３０ｍｍ程度）を取り付けておくことにより、通気性を良くし、接着剤５の硬化率を向上させることができる。又接着剤５に厚みを持たせているため、接着剤５を切断して太陽電池モジュール３を取り外すことが容易なようになっている。
【００１１】
【発明の効果】
以上説明したように、本発明の太陽電池モジュールを屋根に取り付ける施工方法によると、屋根と太陽電池モジュールの設置高さを抑えることができるため、建築限界間際に施工された建築物の屋根に太陽電池モジュールを取り付ける際、特に有利に作用する。又従来例に比較して手間がかからず、経済性についても有利なようになっている。更にケーブルの位置ずれを防止することができるため、ケーブルの取り換えの際、ケーブルを探す手間が無くなる。
