Abstract: According to the present invention, a resin composition for a solar-cell encapsulating material includes an ethylene·±-olefin copolymer of which an MFR measured based on ASTM D123 8 under conditions of 190°C and a load of 2.16 kg is equal to or less than 10 g/10 minutes, a silane coupling agent, and a hindered amine-based photostabilizer. pH of the hindered amine-based photostabilizer, which is measured by using the following measuring method is equal to or less than 9.0. In the measuring method, the pH is measured by using a potential difference measuring device and by using a solution which contains 10 g of acetone, 1 g of water, and 0.01 g of the hindered amine-based photostabilizer, as a sample.
