Provided is a biaxially stretched polyester film in which a thickness is from 200 µm to 800 µm, fracture strength in both a longitudinal stretching direction and a lateral stretching direction is from 180 MPa to 300 MPa, an internal haze (Hin) is from 0.3% to 20%, a difference (”H = Hsur - Hin) between an external haze (Hsur) and the internal haze (Hin) is 2% or less, and an intrinsic viscosity is from 0.68 to 0.90, a method of the biaxially stretched polyester film, a solar cell power generation module using the biaxially stretched polyester film. |
