Product Briefing Outline: ISRA Vision has introduced an advanced optical multi-panel inspection system called Powerscan for automated inspection of glass, surface, and laminates for the photovoltaic industry. Based on its standardised modules and software, ISRA has developed a special system setup to inspect thin-film solar modules right after lamination.
Problem: In order to be able to run PV manufacturing facilities 24/7, one of the keys to success is to be able to feed the manufacturing process with materials of only the highest quality. In addition, it is necessary to protect and control these complex processes and to generate production data in order to be able to determine each available optimisation possibility, so as to ensure and increase the yield the customers are aiming for.
Solution: The original task of the Powerscan for lamination inspection is to detect laminated bubbles, shrinkage, and excessive PVB as well as edge defects and scratches on the glass itself. Based on its modular product structure in regard to the cameras, illumination, and frames, ISRA is able to solve nearly each inspection task. Additional features include state of- the-art interfaces, inspection of flexible batches, and high-performance inspection tasks within the thin-film solar industry
Applications: Inspection of laminates including incoming glass inspection, edge inspection, coating inspections (such as TCO) and scribing inspection.
Platform: ISRA Vision employs standard modules and standard components, engineered and manufactured in-house. This practice guarantees the highest level of customer flexibility. Systems are claimed to have a high acceptance and performance with safe and repeatable error recognition, unique real-time capabilities, as well as robustness and reliability.
Availability: March 2010 onwards.
