Iron content of solar glass

How much iron is in solar glass?

As one of the most crucial components of solar installations, photovoltaic glass demands high transparency. Therefore, strict requirements are imposed on the iron content in the silicon raw materials used for producing solar glass, with Fe2O3 content typically ranging from 140 to 150 ppm.

What is low iron solar glass?

Low iron solar glass offers numerous compelling advantages that make it the preferred choice for solar energy applications. First and foremost, its exceptional transparency allows for up to 91% light transmission, significantly higher than conventional glass, directly translating to improved solar panel efficiency and increased energy generation.

What is Solar Photovoltaic Glass?

This article explores the classification and applications of solar photovoltaic glass. Photovoltaic glass substrates used in solar cells typically include ultra-thin glass, surface-coated glass, and low-iron (extra-clear) glass.

How does iron affect the color of glass?

The presence of iron impurities not only causes the glass to become colored but also increases its heat absorption rate, thereby reducing its light transmission. Iron in glass comes from raw materials, refractory materials, or metal equipment used in production, and it is impossible to completely avoid its presence.
