CSG low iron solar glass, designed and developed independently by CSG, is the new generation of glass for solar modules and CSG reserves the products’ Intellectual Property Rights. The glass observes the properties of high solar transmittance, superior physical strength and significant flatness. Besides, with other performances and specifications equal to or better than those of similar products on global market, the products will adequately meet the solar industries booming demands on high quality low iron glass. Therefore, the solar modules manufacturers’ competitive ability will tremendously hike in solar energy markets.

Anti-reflective Coating
Low-iron solar glass, combined with nanometer anti-reflective coating technology, is applied for solar modules. It increases solar transmittance by way of decreasing light reflectance, thus increasing the solar cell efficiency. Besides, it reduces the reflected glare of the glass and the pollution caused by the reflectance to the environment. The super water-wet behavior of the coating could in some degree protect the dust and dirt from shading the light and improve the self-cleaning of the glass so that the solar cell could maintain high efficiency. Light Transmittance：Increase by above 2%（400-1100nm）Module Output：Increase by above 2%
