Yoha Solar has achieved another breakthrough in overseas market expansion. On May 26, four sets of core PV testing equipment were fully assembled and shipped to overseas PV module production lines for local mass production quality inspection. The shipment consists of two sets of YHEL-1590 Solar Mini Module EL Defect Detectors, one set of YHMT-1590 Solar Mini Module IV Tester, and one set of YHCT-AAA Solar Cell IV Tester. Covering the full-process inspection of single solar cells, mini-module performance testing and internal defect screening, these domestically developed high-precision devices empower the high-quality and efficient development of the global PV industry.
As a core quality control device for PV manufacturing, the YHEL-1590 Solar Mini Module EL Defect Detector adopts mature electroluminescence non-destructive imaging technology to realize non-contact and damage-free module inspection. Equipped with a 24-megapixel high-definition imaging system and a dedicated darkroom imaging design, the tester accurately identifies micro defects below 0.03mm, including micro-cracks, broken grids, black cells and sintering flaws, eliminating potential performance risks of PV modules. Compatible with monocrystalline and polycrystalline modules for full-process detection before and after lamination, it features an effective testing area of 1500×900mm with adjustable image acquisition time ranging from 1s to 60s. Supporting both on-line and off-line detection modes, it serves as a key device for quality control and yield improvement in PV production.
The YHMT-1590 Solar Mini Module IV Tester, delivered together with the EL detector, is specially developed for high-precision photoelectric performance testing of mini PV modules. Adopting A-class pulsed light source with a spectral range of 300–1200nm, it precisely simulates standard test environments and completes IV curve scanning within milliseconds. The equipment achieves light intensity inhomogeneity and instability within ≤2%, electrical performance measurement error ≤2%, and test result consistency ≤1%. It automatically calculates core module parameters including open-circuit voltage, short-circuit current, maximum power and conversion efficiency, supporting intelligent grading judgment and traceable data export, which perfectly adapts to batch quality inspection, power sorting and failure analysis scenarios of overseas production lines.
The supporting YHCT-AAA Solar Cell IV Tester focuses on refined single-cell detection. It is fully compatible with all types of solar cells including monocrystalline, polycrystalline, PERC, TOPCon and HJT cells, covering full cell sizes from 125mm to 210mm. With a measurement accuracy within ±0.5%, it collects full-dimensional photoelectric parameters in milliseconds. Featuring an integrated lightweight design and simplified manual operation, it is applicable to diverse scenarios such as laboratory R&D and debugging, incoming quality inspection and small-batch sampling testing. It supports one-click test report export and ensures complete cell integrity via non-destructive testing, effectively reducing testing loss and operational costs for manufacturers.
