図1は、本発明にかかる太陽電池モジュールの組み立ての初期工程の様子を示す斜視図である。図2は、太陽電池パネルの外縁部に枠状フレームを取り付けた中間組立体に裏面から補強フレームを取り付ける様子を示す斜視図である。図3は、中間組立体への補強フレームの取り付けが完了した様子を示す斜視図である。
図8は、本発明にかかる太陽電池モジュールの実施の形態2の緩衝材が太陽電池パネルと補強フレームとの間に挟まれて配置される様子を示す斜視図である。図9は、実施の形態2の緩衝材を3方向から見た様子を示す図である。図8及び図9に示すように、本実施の形態の緩衝材32においては、太陽電池パネル20と対向する第1主面は、太陽電池パネル20とフラットに接するように概ね平らな平坦面32aとなっている。
図11は、本発明にかかる太陽電池モジュールの実施の形態3の緩衝材の斜視図である。図12は、本実施の形態の緩衝材により補強フレーム側からの反力が分散された様子を示す模式図である。本実施の形態の緩衝材33は、概略直方体の平板状を成し太陽電池パネル20と対向する第1主面は平坦面33aである。そして、補強フレーム3に対向する第2主面の補強フレーム3の長手方向両端部の中央部に、それぞれ切り欠き33bが設けられている。別な言い方をすれば、切り欠き33bは、補強フレーム3の長手方向両端面の補強フレーム3側の辺の中央部に設けられている。すなわち、切り欠き33bは、従来局所応力集中点P(図6)があった補強フレーム3の長手方向両端面の太陽電池パネル20側の辺に対向する辺の中央部に設けられている。
図13は、本発明にかかる太陽電池モジュールの実施の形態4の緩衝材の斜視図である。図14は、本実施の形態の緩衝材を3方向から見た様子を示す図である。本実施の形態の緩衝材34は全体的に蛇腹状になっている。本実施の形態の緩衝材33においては、太陽電池パネル20と対向する第1主面と補強フレーム3に対向する第2主面の両主面の全体に補強フレーム3の短手方向に延びる複数のひだ34aが形成されており、補強フレーム3の長手方向に伸縮するとともに、厚さ方向に弾性を有するようになっている。
