Yingli partners with Longi on mono products

Yingli Green Energy Holding Company Limited today announced that it has signed a framework agreement with Xi’an Longi Silicon Materials Corp to cooperatively manufacture monocrystalline silicon wafers, and ingots, solar cells and solar panels. The new partnership will help Longi, the world’s largest monocrystalline silicon manufacturer, expand into solar panel assembly while also enabling Yingli to integrate Longi’s technology into its production lines.

According to the agreement, the two parties will collaborate to employ their respective manufacturing capacities, technologies and resources across the full monocrystalline value chain, from monocrystalline ingots and wafers to solar cells and panels. For example, when producing ingots, Yingli will integrate Longi’s technology and cost-saving advantages into its own production lines, and Longi will supply high quality monocrystalline wafers to Yingli at a competitive price.

Under the same agreement, Yingli will preferentially procure Longi’s monocrystalline silicon wafers. In the meanwhile, both parties agreed to develop high-efficiency monocrystalline solar application markets from home and abroad and consider to use monocrystalline modules for their self-developed power plants, further to explore the possibilities to jointly develop monocrystalline silicon ingot plants.

"We are pleased to begin collaborating with Longi, a world leader in the production of monocrystalline silicon. Our partnership enables Yingli to make full use of its manufacturing capacity by both optimizing allocation and reducing costs," commented Liansheng Miao, Chairman and Chief Executive Officer of Yingli Green Energy.

Baoshen Zhong, Chairman of Xi’an Longi commented: "As the global solar industry expands and innovative new PV applications are adopted, demand for high-efficiency monocrystalline technology is growing swiftly. By working together, Yingli and Longi can more effectively meet this rising demand for high-performing, cost-effective monocrystalline PV solutions in the global marketplace."
