The Dr. Schenk SolarInspect series is designed to fulfill the special requirements throughout the production of crystalline solar modules. These turnkey vision systems offer reliable quality control throughout the running production process. In addition, continuous monitoring of the production process allows timely corrective action to be taken when process deviations appear.

Instead of bare glass patterned glass substrates are used in the production of crystalline solar modules. Patterned glass increases the amount of incoming sunlight. The surface structure as used for glass substrates of silicon solar modules inclines to create similar or even stronger optical signals in the vision system then the actual inspected defect.

Dr. Schenk has developed and manufactured SolarInspect, a system specialized to precisely distinguish between glass structure and defects covering 100 percent of the material surface including the edges.

By applying an innovative optical set-up the Dr. Schenk inspection system can clearly identify the glass defects and differentiate them from the glass structure.
