Visit the first “lighthouse factory” in the global photovoltaic industry, and Longi accelerates the arrival of the full scene of BC
Achieve 43% increase in product quality and reliability, 84% reduction in product production and delivery cycle, and 20% reduction in overall unit energy consumption of the base… This is the report card obtained by the construction of “lighthouse factory” in Longji Jiaxing Base.
Longji Jiaxing Base was established in 2020, the main production of Longji BC series high-efficiency solar cell modules, Longji Jiaxing base existing Jiaxing phase I, II, III factories, a total area of more than 1300 acres, with 51 intelligent production lines, the overall module production capacity of more than 35GW, is the industry’s largest industrial cluster.
Recalling that on December 14, 2023, the World Economic Forum (WEF) released the list of the latest batch of “lighthouse network”, Longji Jiaxing Base is the only shortlisted factory in the global photovoltaic industry. This marks that Longi’s achievements in the field of intelligent manufacturing and digitalization lead the world, become a representative of advanced manufacturing, and the first world “lighthouse factory” in the photovoltaic industry has also attracted attention from all parties.
Recently, the reporter had the honor to visit the Longji Jiaxing base, in-depth lighthouse factory production line, immersive feeling the “lighthouse factory” intelligent charm, and truly feel the AI intelligence of the traditional industry subversive upgrade, Longji lighthouse factory innovation is not only in the production line automation and intelligent transformation, but also the reconstruction of production relations. Let AI intelligence become the brain of production management, based on big data models, and constantly innovate independently to achieve the true sense of intelligent upgrading of self-drive.
1. What are the main driving factors for the innovation of Longi Lighthouse Factory?
”One is to meet the changing and diversified requirements of customers, and the other is to ensure the consistency of production processes at different production bases.” Zhang Haimeng, vice president of Longi Green Energy, admitted to the observer network that Longi has two main driving factors for building a “lighthouse factory”.
As we all know, the core of photovoltaic technology moving forward has always been around improving efficiency and reducing the cost of kilowatt-hour electricity. Longi has always attached great importance to technology research and development, driven productivity by science and technology, constantly improving conversion efficiency, and constantly approaching the theoretical limit of conversion efficiency. Longi’s self-developed back-contact crystalline silicon heterojunction solar cell (HBC) achieved 27.30% conversion efficiency, creating a new world record for single-crystalline silicon solar cell efficiency; The self-developed crystalline silicon-perovskite laminated cell efficiency set a world record of 33.9%.
However, the global photovoltaic industry has entered a more customer-oriented era. With the development of the photovoltaic industry, the needs of customers began to become diversified, including Longi photovoltaic companies began to realize a problem: how to produce modules to meet the real requirements of customers.
All customer-centric Longi began to realize that in the large-scale manufacturing process of photovoltaic, not only to improve the conversion efficiency from the research and development end, but also to ensure higher efficiency in the manufacturing process, to meet the diverse requirements of customers, flexible production of components suitable for different application scenarios, and faster delivery of products to customers. The use of traditional assembly line production, to meet these needs is obviously powerless.
In addition, with the expansion of component production scale, more and more component production sites are scattered around the world, closer to the end market. How to ensure the consistency of the component production process, ensure that the component product delivery requirements are met, and meet local compliance and product certification requirements is another issue facing photovoltaic companies.
”In this process, we see not only the factory itself through the certification, but the ability to provide service to customers, and superimposed on the product, product quality, product efficiency, product performance, the formation of structured capabilities.” “This capability can be delivered as value to our customers and partners, which is one of the things we are most excited about in building the Lighthouse factory,” said Haimeng Zhang.
2. The core four elements of Longji Lighthouse factory
The combination of artificial intelligence, big data, cloud platform and industrial texture is the four elements of the achievement of Longi Lighthouse Factory, and is also the core of Longi intelligent Manufacturing. Longji BC full scene products have also moved to a new level under the blessing of Longji Intelligent manufacturing.
It is understood that Longi’s newly launched Hi-MO X6 Max components will officially start production at the base in the near future. Hi-MO X6 Max series products are based on the core value of Hi-MO X6, equipped with the new Longi Terre Inside technology, and continue the excellent gene of HPBC battery, with the M11 rectangular silicon chip known as the “gold size” and the leading industry standard 2382×1134mm module size. New breakthroughs in product stability, reliability and power generation efficiency have been achieved.
Prior to this, based on BC technology, Longi released a number of new scenario-based components Hi-MO X6 anti-ash components, Hi-MO X6 double glass moisture and heat resistance components, Hi-MO 9, whose core purpose is to meet the customized needs of customers through differentiated innovation.
In this respect, Zhang Haimeng, vice president of Longi Green Energy, said that since the official announcement of BC technology in September last year, Longi has released a number of new scenario-based components, whether it is anti-ash or humidity and heat resistance, its core purpose is to meet the customized needs of customers through differentiated innovation, all of which cannot be separated from the production of hard power confidence brought by Longi intelligent manufacturing, which is also the strong support of Longi intelligent manufacturing. So that “customer-centric” has been the real practice.
Of course, the lighthouse factory has brought far more changes to Longi. For employees, the Lighthouse factory improves their working environment, enables them to master the application of digital tools, enhances their work skills, and achieves higher quality employment. Zhang Haimeng said: “This is the lighthouse factory one of the biggest benefits.”
On the day of the event, Longi also officially announced the launch of the “Lighthouse Plan”, which will continue to rapidly expand the agile intelligent manufacturing model of Longi Jiaxing Base lighthouse factory to more manufacturing bases. “The Longji Jiaxing Lighthouse factory is just a starting point, and we hope to build it into a high standard factory that can be replicated in the future,” said Zhang Haimeng.
