Product Introduction

The OPT-M950B/M951B Automatic Solar Panel EL & VI Defect Tester represents the pinnacle of solar module quality inspection technology. This advanced testing system combines Electroluminescence (EL) and Visual Inspection (VI) capabilities to provide comprehensive defect detection for solar manufacturing lines. Designed by Ooitech (www.ooitech.com), a leading provider of solar panel production line equipment from 5MW to 1GW capacity, this system ensures the highest quality standards in photovoltaic module production.
The system utilizes sophisticated SONY industrial cameras and intelligent image processing algorithms to detect various defects including cracks, breakage, black spots, mixed wafers, process defects, and cold solder joints. With its dual-mode capability (M950B with EL+VI, M951B with EL only), manufacturers can choose the configuration that best suits their quality control requirements. The tester seamlessly integrates into existing production lines, supporting conventional modules, double-glazed modules, thin film modules, and half-cell modules.
