SURFACE PROTECTION SHEET FOR SOLAR CELL MODULE

PROBLEM TO BE SOLVED: To provide a low price and safe surface protection sheet for solar cell modules rich in transparency for transmitting sunlight, excellent in strength, excellent in durability such as weatherability, heat resistance, water resistance, light resistance, wind resistance, hail resistance, chemical resistance, and puncture resistance, and excellent in easiness of inventory control of materials because only one raw material is required for different applications due to the characteristics that the film thickness of a thermosetting transparent resin layer can be freely controlled. SOLUTION: The surface protection sheet for solar cell modules comprises a substrate film and a thermosetting transparent resin layer formed on the film. The thermosetting transparent resin layer comprises a resin prepared by copolymerizing a vinyl ester resin, a monomer which is copolymerizable with the vinyl ester resin and whose homopolymer has a Tg of -20°C or lower, and a monomer which is copolymerizable with the vinyl ester resin and whose homopolymer has a Tg of 120°C or high.
