PROBLEM TO BE SOLVED: To provide a solar battery module having excellent impact resistance.SOLUTION: A solar battery module has a surface member having an incidence face to which sunlight is incident, and an emission face at the opposite side to the incidence face; plural solar battery cells arranged along the emission face, each solar battery cell having a front surface confronting the emission face and a back surface at the opposite side to the front surface; an interconnector for connecting the surface of a solar battery cell and the back surface of another solar battery cell adjacent to the former solar battery cell; a sealing material layer which is provided to the emission face side of the surface member and contains the plural solar battery cells and the interconnectors therein; and a back surface member provided to the back surface side of the plural solar battery cells with respect to the sealing material layer. The back surface member is configured so that the Young's modulus Eb at 23°C and the thickness Tb of the back surface member have a predetermined relationship, and the interval d1 between the solar battery cell and the back surface member and the Young's modulus Eb at 23°C of the sealing material layer have a predetermined relationship.

    【課題】優れた耐衝撃性を有する太陽電池モジュールを提供できる。【解決手段】太陽光が入射する入射面と入射面の反対側の出射面とを有する表面部材と、出射面に対向する表面と表面の反対側の裏面とを有し、出射面に沿って配列された複数の太陽電池セルと、太陽電池セルの表面と、当該太陽電池セルと隣り合う他の太陽電池セルの裏面と、を接続するインターコネクタと、表面部材の出射面側に設けられ、複数の太陽電池セル及びインターコネクタを内部に有する封止材層と、封止材層に対して複数の太陽電池セルの裏面側に設けられた裏面部材と、を備え、裏面部材は、23℃におけるヤング率Ebと裏面部材の厚さTbとが所定の関係を有すると共に、太陽電池セルと裏面部材との間隔d1と封止材層の23℃におけるヤング率Ehとが所定の関係を有する。【選択図】図2
