摘要:
Disclosed is a solar cell module capable of suppressing light leakage from a front plate and improving an optical confinement property. A solar cell module 1 includes a plurality of bifacial solar cell elements 2, a front plate 4 which is arranged on the front side of the solar cell elements 2, and a back plate 5 which is arranged on the back side of the solar cell elements 2 and has a light-reflecting surface 5a reflecting sunlight incident into the module from the module front side. When the refractive index of the front plate 4 is n, the inclination angle Φ (radian unit) of the light-reflecting surface 5a relative to the array direction of the solar cell elements 2 is set as follows between a cell interval center line A and a cell end line C. That is, in a region X between the cell interval center line A and a near-cell line D, the relationship (Φ>0.5×sin −1 (1/n) is established. In a region Y near the cell end line C, the relationship (Φ
