Yoha Solar has delivered and commissioned its self-developed YHCT-AAA solar cell IV sorter, which is officially in mass production operation on a domestic semi-automatic PV module line. Delivering high-precision, high-stability cell performance testing and sorting, the equipment upgrades final product quality and verifies Yoha Solar’s professional strength in intelligent PV inspection manufacturing.
YHCT-AAA solar cell IV sorter
As a core end-of-line quality control device for solar cell production, the YHCT-AAA IV sorter accurately captures I-V curves and calculates key parameters including open-circuit voltage, short-circuit current, maximum power, fill factor and conversion efficiency. It supports monocrystalline and polycrystalline cells, as well as mainstream PERC, TOPCon, HJT and SUNPOWER technologies, fully adapting to diverse modern PV manufacturing testing demands.
Fully compliant with the IEC60904-9:2020 international standard, the tester adopts imported Heraeus pulsed xenon lamps with a 300~1200nm spectrum that perfectly matches AM1.5 irradiance distribution. It features adjustable irradiance from 700W/m² to 1200W/m² (standard 1000W/m²), with both irradiance non-uniformity and instability controlled within ±2%. The 10ms short pulse design guarantees consistent, repeatable testing results.
High-precision electrical performance testing
Equipped with four-wire measurement technology and a 16-bit 4-channel high-speed synchronous acquisition card, the device collects up to 8,000 data points per test. It achieves 1mV voltage resolution and 1mA current resolution, with overall measurement error and inconsistency within ±1%, precisely identifying minor cell performance differences. Covering a 0.1W–15W power range and completing single tests within 5 seconds, it perfectly matches high-frequency mass production inspection rhythms.
Featuring user-friendly intelligent configuration, the device integrates a touch screen and self-developed testing software to auto-generate I-V and P-V curves, with real-time irradiance and temperature dual compensation. It supports Chinese/English bilingual interfaces, voice prompts, automatic data storage, statistical summary, Excel export and serial number increment, enabling full data traceability and refined production management.
Focusing on intelligent PV inspection equipment, Yoha Solar insists on strict quality control and customer-centric services. With mature technologies, stable equipment performance and comprehensive pre-sales and after-sales support, the company has earned solid industry reputation and widespread client trust.
This successful on-site operation fully recognizes Yoha Solar’s premium product quality and technical competitiveness. Moving forward, Yoha Solar will continuously iterate intelligent PV testing technologies and optimize equipment performance, empowering high-quality and sustainable development of the global PV industry with high-precision, high-stability inspection solutions.
