PROBLEM TO BE SOLVED: To provide a resin composition for a solar cell sealing material which includes, as a base, an ethylene-polar monomer copolymer, and enables the suppression of PID phenomenon, and by which a solar cell module of which the electric property is stable over a long period of time can be obtained.SOLUTION: A resin composition for a solar cell sealing material comprises: an ethylene-polar monomer copolymer; a silane coupling agent; and a hindered-amine based photostabilizer. The hindered-amine based photostabilizer measured according to a measurement method below is pH 9.0 or less. (Measurement method), in which the pH is measured with a potential difference measuring device using, as a sample, a solution including 10 g of acetone, 1 g of water, and 0.01 g of the hindered-amine based photostabilizer. |
