## Summary

Q CELLS, now operating under the Hanwha Qcells brand, traces its origins to a German manufacturer founded in 1999 before South Korea's Hanwha Group acquired it in 2012. Today the company is headquartered in Seoul with major module production facilities in Dalton and Cartersville, Georgia, giving it the largest solar manufacturing footprint in the United States. It holds a long-standing Bloomberg New Energy Finance Tier 1 listing and its combined US capacity across those two plants reaches 8.4 GW per year, with global module shipments expected to exceed 9 GW in 2025. Sunpro Power - formally Zhejiang Sunpro Power Technology Co., Ltd. - is a Chinese manufacturer headquartered in Yuhuan, Zhejiang province, with a second production base in Wuxi. Founded around 2018, it has maintained Tier 1 status on the BloombergNEF list continuously since Q2 2022 and expanded annual production capacity to 3 GW as of Q1 2025. On scale, institutional history, and geographic reach, Q CELLS carries the distinctly stronger footprint.

Q CELLS serves residential through utility segments, with its current flagship being the Q.TRON line - an N-type TOPCon module built on the company's proprietary Q.ANTUM NEO technology, rated up to 22.5% efficiency and designed for premium residential and light-commercial rooftops. Older PERC-based Q.ANTUM products remain available for cost-sensitive commercial buyers, and US-assembled panels qualify for Inflation Reduction Act domestic content incentives. Sunpro Power offers a notably wider catalog, covering PERC, TOPCon, and HJT cell technologies in both monofacial and bifacial configurations across a broad wattage range. That flexibility positions it primarily as a value-oriented supplier for international commercial and small utility projects, typically sold through EPC contractors and module resellers rather than direct retail.

For most buyers in 2025 - particularly in North America or Western Europe - Q CELLS is the more defensible choice: its Tier 1 standing is well-established, its US-made panels attract domestic content bonuses, and its after-sales network in Western markets is widely documented. Sunpro Power is a credible budget alternative for markets where procurement price is the primary driver and supply-chain provenance is a secondary concern; its Tier 1 certification provides enough assurance for project finance in those contexts. The two brands are not interchangeable - Q CELLS competes as a premium institutionally trusted name, while Sunpro Power occupies a mid-market niche with a broader technology menu but a shorter commercial track record.
