Thin Film (RollToRoll) Solar Module Inspection

Optical inspection systems play an important part when it comes to the optimization of the production process to improve yield and maximize the output quality.

SolarInspect for Thin Film (RollToRoll) inspection from Dr. Schenk has been designed to fulfill the special requirements throughout the production of flexible thin film 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.

Fully integrated after relevant production steps, the SolarInspect RollToRoll systems detect, pinpoint and accurately classify defects or irregularities on the surfaces of incoming flexible base materials through to the finished flexible solar module. The user-friendly graphical interface provides clear diagrams and analyzing tools, displaying detailed defect information together with high-resolution images.
