Yaohua Laser’s YH-EL8 PV Module EL & Visual Defect Detector Shipped Smoothly, Empowering Overseas 100MW Production Line

Wuhan, China – March 12, 2026 – Wuhan Yaohua Laser Technology Co., Ltd. has successfully completed the shipment of a batch of core photovoltaic (PV) testing equipment. The independently developed YH-EL8 PV Module Electroluminescence (EL) & Visual Defect Detector has officially set off for an overseas 100MW automated PV module production line, where it will be put into mass production. This equipment delivery marks another key achievement of Yaohua Laser’s deep cultivation in the PV intelligent testing sector. With robust product performance and high adaptability, it builds a solid quality control defense line for overseas PV manufacturing links, facilitating the efficient advancement and stable commissioning of overseas PV projects.
Quality control of PV modules is directly linked to the power generation efficiency and long service life of power stations. Internal hidden defects such as hidden cracks, broken grid fingers and poor soldering, as well as visual flaws including scratches, contamination and poor packaging, are all critical hidden dangers affecting module reliability. The YH-EL8 PV Module EL & Visual Defect Detector shipped by Yaohua Laser this time is a high-end automated equipment integrating dual functions of electroluminescence (EL) detection and visible light visual detection. It precisely caters to the full-process quality inspection needs of PV modules, enabling one-stop intelligent identification, positioning and analysis of internal and external defects of modules, making it an indispensable core quality testing device for modern PV production lines.

Robust Performance Delivers Comprehensive Solutions to Module Testing Pain Points

Backed by industry-leading technical configurations, the equipment has achieved comprehensive upgrades in testing accuracy, efficiency and intelligence. Adopting an 8-camera area array shooting mode and equipped with professional industrial cameras, it boasts an EL detection resolution of 60 megapixels and a visual detection resolution of up to 240 megapixels. In a darkroom environment, it can accurately capture luminous images of energized modules with extremely high sensitivity, effectively detecting tiny cracks with a width of less than 0.03mm and completely eliminating the risk of missing minor defects.
Meanwhile, the equipment integrates advanced image processing and AI intelligent algorithms, abandoning the inefficiency and errors of traditional manual testing. It automatically completes defect classification, analysis and judgment, coupled with millisecond-level image acquisition and processing speed – the image collection time only takes 100 to 700ms. This perfectly matches the high-throughput, fast-paced production demands of the overseas 100MW production line, balancing testing accuracy and production efficiency to ensure a steady improvement in module yield.
In terms of functional adaptability, the YH-EL8 detector covers the testing of various monocrystalline and polycrystalline battery modules, supporting full-process defect screening of modules before and after lamination. It can accurately identify internal microscopic defects such as hidden cracks, fragments, broken grid fingers, poor soldering and black chips, and efficiently detect visual flaws including scratches, edge chipping, contamination, color difference and ribbon offset, realizing integrated and all-dimensional testing.
The equipment adopts an automatic loading/unloading and online automatic testing mode, with an effective testing area of 2600*1500mm that matches mainstream PV module specifications. It can also generate clear and intuitive defect reports and visualized data, providing a reliable basis for production process optimization and quality traceability, and fully meeting the standardized and refined quality inspection requirements of overseas production lines.
