Quality standards for finished solar glass products

How can solarinspect ensure the quality of the finished modules?

To ensure the quality of the finished modules, the control of the dimensions and shape (rectangular-ity) of the glass substrates is essential. SolarInspect provides this capability parallel to the glass defect detection.

Why is patterned glass used in crystalline solar modules?

In the production of crystalline solar modules pat-terned glass substrates are used in lieu of bare glass. Patterned glass increases the amount of incoming sunlight. Common optical inspection systems for quality assurance and process control are mostly designed for unstructured glass.

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 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.
