Ultra clear glass for photovoltaic solar panel is made of low iron content raw materials. It is used for front cover of crystalline silicon (cSi) including mono-crystalline solar panels, polycrystalline solar panels. Ultra clear characteristic allows higher light transmission. Glass surface consists of special design pattern which further permits more light transmission. The pattern also concentrates and focus transmitted light onto energy absorbent behind the glass. Like ordinary clear float glass, solar glass could be further processed such as cutting, grinding, drilling, tempering, laminating, mirroring, coating and printing, etc.
