Overcoming Traditional Lighting Limitations! Yoha Solar’s Upper Lighting Solar Module IV tester Deployed at Core Overseas PV Production Base
Deeply rooted in the PV inspection and intelligent manufacturing sector, Yoha Solar empowers global production capacity upgrading through overseas layout. On April 28, Yoha Solar completed factory verification, packaging and shipment of its self-developed and self-manufactured YHMT-HM-A+A+A+ Upper Lighting Solar Module IV tester. The equipment has been officially delivered to an overseas customer’s production plant and put into regular mass production inspection on the local fully automatic PV module production line. The successful overseas deployment marks a major breakthrough in the company’s global market expansion and serves as a crucial practice for Yoha Solar to facilitate high-quality, standardized production of the global PV industry with robust PV inspection equipment and solid technical strength.
Yoha Solar’s Upper Lighting Solar Module IV tester
As an essential quality inspection equipment for PV module manufacturing, the shipped Upper Lighting Solar Module IV tester adopts a dedicated top-lighting design, abandoning the conventional bottom-illumination testing mode. It can accurately simulate the real incident scenario of natural sunlight, perfectly meeting the testing requirements for framed modules, double-glass modules and modules with special installation angles, and realizing high consistency between laboratory testing conditions and outdoor actual application environments. Based on the core non-destructive testing principle, the equipment can quickly map the complete current-voltage characteristic curve and accurately calculate key performance parameters without flipping or moving the tested PV modules, fully adapting to the high-speed continuous production and testing rhythm of overseas fully automatic production lines.
In terms of core testing performance and technical standards, the equipment strictly complies with the international PV testing specification IEC60904-9:2020, with all core indicators reaching the high A+ grade. It covers a spectral range of 300~1200nm, with a standard test irradiance of 1000W/㎡ and flexible adjustment within the range of 200~1200W/㎡. The light intensity non-uniformity is ≤1%, light intensity instability ≤0.5%, test result consistency ≤0.5%, and electrical performance measurement error is strictly controlled within ≤1%, ensuring accurate, reliable, traceable and reusable test data. Meanwhile, the single flash pulse width reaches 100ms, and the effective test area is 2600*1600mm, compatible with the testing demands of mainstream large-size PV modules, with hardware configurations fully meeting the mass production quality inspection standards for overseas markets.
High-precision testing of the electrical performance of PV modules
Compared with traditional testing equipment, Yoha Solar’s Upper Lighting Solar Module IV tester features dual core advantages of high production efficiency and non-destructive protection. During on-line operation, no manual handling or flipping of modules is required, which greatly shortens the testing process time, improves the overall operational efficiency of fully automatic production lines, and eliminates production losses such as micro-cracks and damage caused by module handling and flipping, laying a solid foundation for high product yield. With stable and excellent testing performance, the equipment accurately calculates core parameters including maximum power point, open-circuit voltage, short-circuit current, fill factor and conversion efficiency, supporting overseas customers in core operations such as power sorting, factory quality inspection and incoming material verification, and ensuring consistent and stable performance and quality of batch PV modules.
As the global PV industry accelerates large-scale and standardized development, high-quality inspection equipment serves as the core support for product quality improvement and production capacity upgrading. The overseas launch of Yoha Solar’s core testing equipment fully recognizes the company’s product quality and technical strength by the global market. Moving forward, Yoha Solar will continue to focus on the R&D and innovation of PV testing equipment, adhere to refined manufacturing concepts, continuously optimize product performance and delivery service systems, and expand domestic and overseas market layout. With professional and reliable PV intelligent manufacturing and testing solutions, the company will empower the high-quality and sustainable development of the global PV industry.
