TRANSPARENT PROTECTIVE SHEET FOR SOLAR BATTERY MODULES

摘要

PROBLEM TO BE SOLVED: To provide a transparent protective sheet of a coating type arranged to be put on a polyester resin base material, and having a total light transmittance of 90% or larger.SOLUTION: A transparent protective sheet for solar battery modules comprises: a polyester resin base material; and a weather resistant coating layer. The weather resistant coating layer is formed on the polyester resin base material, or formed on a contact-reinforcement layer arranged on the polyester resin base material. The transparent protective sheet has a total light transmittance of 90% or larger. The weather resistant coating layer or contact-reinforcement layer, which is arranged to neighbor the polyester resin base material, contains a compound or polymer having a carbodiimide group.
