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。
このような構成により、気温の変化に伴うレンズと発電素子との距離の変化量がより大きくなるため、気温の変化に伴うレンズの焦点距離の変化量に対して、レンズと発電素子との距離の変化量が追随する可能性を高めることができる。
また、入射光の光軸を確認するための新たな部材を別途用いる必要がないため、低コストを実現することができる。また、光軸の精度を確保するための高い組み付け精度が要求されることもない。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。
このような構成により、複数の視認穴の中から光が透過している視認穴を特定することで、入射光の光軸を容易に確認することができる。また、側壁と光軸確認部とを同じ材料で形成することができるため、たとえば射出成型を行うことで、これら側壁および光軸確認部を比較的容易に低コストで作製することができる。
このような構成により、光軸確認部の底面に光が到達しているか否かを確認することで、太陽光発電モジュールの上面に対して入射光が所定の角度で入射しているか否かを容易に確認することができる。また、側壁と光軸確認部とを同じ材料で形成することができるため、たとえば射出成型を行うことで、これら側壁および光軸確認部を比較的容易に低コストで作製することができる。
このような構成により、たとえば底面側から光軸確認部を目視することで、底面のいずれの位置に光が到達しているのかを確認することができるため、入射光の光軸を容易に確認することができる。また、多くの穴を形成するための加工などを必要としないため、光軸確認部を備える太陽光発電モジュールを低コストで作製することができる。
このような構成により、フレーム部材に筐体を固定する際における光軸確認部の存在を考慮する必要がなくなり、比較的低コストで単純な構成により光軸確認部を備える太陽光発電モジュールを実現することができる。
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。
