Solar Glass

1.Product Features

Low iron solar glass, normally in the patterns of prismatic and matt-matt, are specially designed for encapsulation material of solar modules. The design reduces the direction reflectance and increase the internal reflection that the solar energy can be absorbed effectively. It ensures the maximum transmittance of the soar and raise the efficiency of electricity generation. The glass observes the properties of high solar transmittance, low absorbance, low reflectance, superior physical strength and significant flatness, is the ideal encapsulation material for solar thermal and photovoltaic modules.

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.
