1. A solar cell module comprising a photovoltaic element covered at the light incidence side thereof by a surface covering member comprising at least a transparent surface sealant resin layer and a transparent surface protecting film which is in contact with the transparent surface sealant resin layer and positioned at the outermost surface on the light incidence side thereof, wherein the transparent surface protecting film has a thickness of from 50 to 100 μ

  • m, wherein the use temperature of the solar cell module is 70°

    C. or more and wherein the oxygen permeability of said transparent surface protecting film is not less than 1 cc/m2·

    24 hr·

    atm and not more than 50 cc/m2·

    24 hr·

    atm at 25°

    C./90% RH, whereby the drop in output of the solar cell module caused by yellowing of the surface covering member when subjected to a thermal degradation test at 150°

    C. for 15 hours and then exposed to ultraviolet rays under the output of 100 mW/cm2 in the wavelength range of 300 to 400 nm by use of a metal halide lamp is less than 10%.
