## Summary

Lefeng Solar, formally Ningbo Lefeng New Energy Co., Ltd., is a Chinese manufacturer headquartered in Ningbo, Zhejiang, that has been producing photovoltaic modules since 2005. The company reports an annual production capacity of approximately 2 GW and holds TUV certification for its modules, but it does not appear on BloombergNEF Tier 1 bankability lists available for 2025, placing it in the category of smaller or emerging-tier exporters. Q-Cells, operating as Hanwha Q CELLS under South Korea's Hanwha Group, traces its roots to a German company founded in 1999 and has since grown into one of the most bankable module suppliers worldwide, confirmed at BloombergNEF Top Tier class and projecting shipments exceeding 9 GW in 2025. Q-Cells also operates one of the largest solar manufacturing complexes in the Western Hemisphere in Dalton and Cartersville, Georgia, giving it a unique domestic supply-chain footprint in the U.S. market. On institutional scale and verified bankability, Q-Cells is substantially stronger.

Lefeng Solar concentrates on export-oriented commercial and utility-scale projects, offering N-type TOPCon bifacial modules in power classes broadly spanning 465 W to 670 W, targeting buyers in price-sensitive or emerging markets. Q-Cells serves a wider range of segments: its Q.TRON series applies TOPCon cell technology to premium residential rooftop installations, while the Q.PEAK DUO line remains a broadly installed option for residential and commercial rooftops alike. Independent reviews cite Q.TRON efficiency reaching up to 23.7% in advanced configurations, backed by 25-year product warranties and customer-service satisfaction scores above the industry average.

For most buyers in 2025, Q-Cells is the clearer default choice: its confirmed Tier 1 status, substantially larger manufacturing scale, strong track record with project financiers, and robust warranty terms together reduce both technical and financial risk. Lefeng Solar may suit price-sensitive commercial or utility developers willing to accept less brand recognition and limited third-party coverage, but for lender-financed or bankability-critical projects, Q-Cells is the more defensible selection.
