LONGi has upgraded its Lighthouse Factory in Jiaxing, China to produce LONGi’s back contact modules featuring the new second generation of HPBC 2.0 - Hybrid Passivated Back Contact technology. The modules include the new Hi-MO X10 which was first launched in Europe in December 2024. The X10 has been engineered to significantly improve reliability, cost-efficiency, and long-term performance. It features a multi-layer structure to increase light absorption, reduce the reflection of short-wave light, reduce UV-induced degradation and shading power loss by over 70% compared to TOPCon, and lower hotspot temperatures by 28%. A zero-bus (0BB) bar structure further enhances performance while LONGi’s new TaiRay wafers show a 16% increase in break resistance for greater reliability. The X10 delivers up to 670W of power with 24.8% efficiency, generating up to 30W more power than TOPCon under the same conditions.
LONGi plans to expand its HPBC 2.0 production capacity to 50 GW by the end of 2025. The Jiaxing factory will contribute at least 40% of this capacity, maintaining a production output above 20 GW. For the first time, LONGi has opened its HPBC 2.0 production to the public to see the Hi-MO X10 manufacturing process.

LONGi’s Lighthouse Factory is the only in the global PV industry
With the HPBC 2.0 production upgrade of the company’s Lighthouse Factory, LONGi once again demonstrates its full commitment to back contact technology.
LONGi's Jiaxing factory is currently the only "Lighthouse Factory" in the global PV industry. Recognized as "the world's most advanced factory," it serves as a benchmark for digital manufacturing and Industry 4.0, showcasing the pinnacle of intelligent manufacturing and digitalization worldwide. LONGi aims to develop it into a state-of-the-art manufacturing facility that can be replicated in the future.
The Jiaxing Production Base was recognized by the World Economic Forum (WEF) as a Global Lighthouse Factory in December 2023, becoming the world's first solar module production base to join the WEF's Global Lighthouse Network (GLN).
