まず、本実施形態に係る太陽光発電装置100の構成について説明する。
次に、本実施形態に係る太陽光発電装置100の製造方法について説明する。
本実施形態に係る太陽光発電装置100の製造治具50は、一対のレール20を有する太陽電池アレイ1を保持するための太陽光発電装置100の製造治具50である。図9に示されるように、本実施形態に係る太陽光発電装置100の製造治具50は、一対のレール取付け部52(一対の取付け部52)と、中央領域51とを有している。一対のレール取付け部52は、一対のレール20が取り付けられる部分である。中央領域51は、一対のレール取付け部52の間に設けられている。つまり、中央領域51は、一対のレール取付け部52によって挟まれている。中央領域51には、挿通孔54が設けられている。挿通孔54の断面形状は、円形である。製造治具50の材料は、特に限定されないが、たとえばアルミニウムまたはステンレスである。
