On March 17, customized PV testing equipment from Wuhan Yoha Solar Technology Co., Ltd. was successfully packed and shipped to an overseas 50MW PV module production line for large-scale production. These three self-developed core devices cover cell performance testing, module IV characteristic measurement and module defect inspection. With precise, efficient and reliable performance, they build a solid quality control barrier for overseas PV lines and further highlight Yoha Solar’s technical prowess and overseas service capacity in the PV testing field.
The delivered core equipment is tailored to the full-process quality inspection needs of the 50MW overseas PV module line. Each device is professionally R&D-designed with compliant parameters, superior performance and strict adherence to PV industry testing standards, boosting efficient line operation.
YHCT-AAA Solar Cell Sorter/IV Tester: Precisely Controlling Core Performance of Solar Cells
Designed for single solar cell photoelectric performance testing, this device targets industry pain points of inaccurate, slow and inconvenient testing. Equipped with high-precision modules and professional algorithms, it delivers ±0.5% measurement accuracy and collects full-dimensional IV parameters (open-circuit voltage, short-circuit current, conversion efficiency) at millisecond speed. Featuring a lightweight manual design, it requires no complex installation and supports instant testing. Compatible with monocrystalline, polycrystalline, PERC, TOPCon and HJT cells (125mm-210mm sizes), it covers incoming inspection, sampling testing and process debugging, providing accurate data for cell quality screening and efficiency evaluation.

YHMT-AAA Long-Pulse Module IV Tester: Solving Testing Challenges of High-Capacitance Photovoltaic Modules
Targeting high-capacitance modules (large-size, double-sided, laminated), this tester adopts a long-pulse light source to simulate real solar irradiation, eliminating capacitance and thermal effect errors of traditional flash testers for more realistic outdoor testing conditions. Its light source meets IEC 60904-9:2020 Class A spectrum standards, with light intensity non-uniformity and instability ≤±2%, and electrical performance measurement error ≤2%. It accurately calculates core parameters like module power point and fill factor, adapts to automated line testing, enables rapid module grading and meets high-efficiency module testing demands.

YHEL-2400 Solar Module EL Defect Detector: Non-Destructive Detection of Micro Quality Hidden Dangers
Leveraging electroluminescence (EL) non-destructive imaging, this detector conducts non-contact internal defect testing for PV modules in dark environments. Fitted with a 48-megapixel customized high-sensitivity infrared camera, it identifies micro-cracks, broken grid fingers and cold solder joints smaller than 0.03mm with clear imaging and precise positioning. Supporting single/dual-camera modes (2600*1500mm effective test area), it adapts to pre- and post-lamination testing, covers raw material inspection, production and finished product delivery, blocks defective products upstream and ensures long-term module power reliability.
