LONGi’s Wuhu production base has been awarded China Manufacturing Maturity Model (CMMM) Level 4 certification, becoming the first module factory in the PV industry to receive such recognition, following its Jiaxing production base being recognized as a “Lighthouse Factory” by the World Economic Forum.
CMMM is a national standard system for evaluating smart manufacturing levels. Assessments are conducted based on two national standards, the maturity model of intelligent manufacturing capability (GB/T 39116-2020) and the maturity assessment method of intelligent manufacturing capability (GB/T 39117-2020), the system classifying smart manufacturing capabilities into five levels.
To date, no domestic business has achieved the highest Level 5, with Level 4 considered the “Optimized” level, requiring a company to realize data-driven self-learning, self-adaptation and continuous optimization in core production and manufacturing processes.
As the core production base for BC modules including Hi-MO 9 and Hi-MO X10, LONGi’s Wuhu base has deployed seven major AI engines, applied respectively to employee skill management, production scheduling, quality inspection, equipment maintenance, process optimization, energy management and warehousing and logistics.
Data shows that the base’s full-chain AI quality inspection platform has increased defect detection efficiency by 80% and reduced the incidence of quality issues across the entire production line by 40%. Through equipment and process upgrades in the four major workstations of screen printing, welding, layout and repair, production efficiency has increased by 21%. The intelligent dispatch system has improved efficiency by 60%, and the “air-water coordinated” AI intelligent control system has reduced overall energy consumption by 7%.
The smart manufacturing capabilities of the Wuhu base ultimately translate into shorter delivery lead times, more stable quality performance and more transparent carbon footprint data. The Hi-MO 9 module, which previously earned the PV industry’s first “all-scenario reliability” certification, rolled off the production line at this very plant. Its high reliability across different climate and terrain conditions is underpinned by smart manufacturing capabilities such as AI quality inspection, predictive maintenance and flexible production scheduling. For end customers, the Wuhu base provides not just a module, but a traceable and verifiable assurance of quality and carbon footprint. Behind all of this lies the production strength brought by LONGi’s smart manufacturing, and it is precisely this strong support that enables the genuine practice of being “customer-centric.”
