Solar glass content requirements

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 are the characteristics of glass for solar applications?

For solar applications the main attributes of glass are transmission, mechanical strength and specific weight. Transmission factors measure the ratio of energy of the transmitted to the incoming light for a specific glass and glass width. Ratio of the total energy from an AM1-5 source over whole solar spectrum from 300 - 2,500nm wavelength.

What is a solar glass substrate?

Manufacturers of crystalline silicon solar modules apply glass substrates on the front side of the solar modules. This front glass will either be a patterned glass or a glass with anti-reflective coating (AR). As in all other glass manufacturing processes, solar glass substrates are subject to defects during produc-tion.

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.
