Technical FAQs 4

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.

Why do solar panels need to be inspected?

Especially critical are those defects that occur at the edges of the glass sheets – an area usually not covered by standard vision systems. Micro-cracks and chips of the solar glass panels are a major cause of glass breakage and their detection is important for assuring highest quality standards.

What happens if a solar glass substrate is defective?

As in all other glass manufacturing processes, solar glass substrates are subject to defects during produc-tion. Depending on the defect type and intensity, the impact of these defects can range from a reduced transmission to a considerable negative influence on the mechanical glass characteristics.

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.
