## Summary

Q-Cells, now operating as Hanwha Qcells under the South Korean conglomerate Hanwha Group, traces its origins to a German cell-technology startup founded around 1999 and acquired by Hanwha in 2012. It holds confirmed BloombergNEF Tier 1 bankability status and has built the largest solar module manufacturing footprint in the Western Hemisphere, with reported US capacity alone reaching roughly 8.4 GW annually and global module capacity approaching 11 GW as of 2025. Sunket New Energy - formally Wuxi Sunket New Energy Technology Co., Ltd. - is a Chinese manufacturer established in 2012 and backed by Delin Holding Group, headquartered in Wuxi, Jiangsu province. It reports an annual module production capacity of around 5 GW, but its BloombergNEF Tier 1 status could not be independently confirmed through available search results. On institutional footprint and bankability track record, Q-Cells holds a clear lead.

Q-Cells is most commonly associated with premium residential rooftops and mid-scale commercial installations in North America, Europe, and Australia. Its current flagship technology is Q.ANTUM NEO, the company's proprietary N-type TOPCon implementation, with module efficiencies reported up to approximately 22.6% in the Q.TRON product line and a 25-year product warranty. Sunket New Energy targets a broader price-tier mix spanning residential, commercial rooftop, and utility-scale ground-mount applications primarily in export markets. Third-party review sources indicate that its current catalog spans TOPCon and PERC cell architectures, with a growing share of bifacial formats, though specific efficiency and warranty figures vary by series.

For a typical buyer in 2025 - particularly one financing a residential or commercial project through a bank or insurer - Q-Cells is the more defensible default, owing to its confirmed bankability status, vertically integrated US supply chain, and established warranty support infrastructure. Sunket New Energy is a credible option for cost-sensitive buyers or system integrators in markets where Q-Cells distribution is limited, but buyers should verify bankability requirements with their financiers before committing.
