The present invention is a method for improving the outdoor exposure properties of a resin member used in a solar power module, comprising a combination of one or two or more functional agents selected from ultraviolet absorbers, light stabilizers, antioxidants as a physical property improving agent used. It is a method of improving the physical properties of a resin member, using one kind or two or more kinds of polymers and adding them internally in the resin material or applying or pasting the surface of the resin material. According to the present invention, the resin member used in the photovoltaic module is exposed to water, steam, acidic water, alkaline water, or the like caused by ultraviolet rays, heat, rainwater, rivers, and groundwater. In addition, it is possible to provide a method of sustaining the resin physical properties in the long term. |
