Solar glass transmittance quality inspection

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.

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.

Which optical inspection systems are used for quality assurance & process control?

Common optical inspection systems for quality assurance and process control are mostly designed for unstructured glass. The surface struc-ture, as used e.g. for glass substrates of silicon solar modules, tends to create similar or even stronger optical signals in the vision system than the actual inspected defect.

Why should you use solarinspect?

Furthermore, SolarInspect can detect glass defects at the edges of the substrate, which helps to avoid unexpected glass breakage in subsequent production and in the final product. 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.
