Low iron solar glass (ultra clear photovoltaic glass), with lightly textured pattern surface, provides excellent light diffusion, which decreases reflection, allows higher light transmission at acute incidence angle and lower absorption by the glass itself.  Our green batch formula assures the product iron content less than 150ppm and conforming to environmental restriction of Europe, America and Japan market. The ultra clear glass is excellent for solar panels.
