## Summary

Q-Cells, operating under the Hanwha Q CELLS brand since South Korean conglomerate Hanwha acquired the original German Q-Cells GmbH in 2012, is headquartered in Seoul, South Korea, with significant manufacturing operations in Dalton, Georgia - the largest solar factory in the Western Hemisphere. The company holds confirmed BloombergNEF Tier 1 bankability status and has reported a combined global production capacity exceeding 11 GW per year across its Korean, Malaysian, and U.S. facilities. Green Energy Supplier, by contrast, does not appear in any of the major industry databases, Tier 1 lists, or independent review outlets consulted for this analysis. It is likely a regional reseller, distributor, or private-label operation rather than a vertically integrated panel manufacturer; no production capacity figures, founding history, or bankability designation could be verified through credible external sources. On institutional footprint, Q-Cells is substantially stronger.

Q-Cells' primary product families are well documented. Its Q.TRON series - built on the company's proprietary Q.ANTUM NEO cell platform, which layers TOPCon architecture with an ultra-reflective rear coating - targets premium residential rooftops and smaller commercial installations, with efficiency ratings confirmed at up to 22.5%. The Q.PEAK DUO series covers mid-range residential and light commercial work, while larger bifacial modules serve utility-scale and agri-solar ground-mount projects. The company's U.S. manufacturing gives it a supply-chain advantage for buyers concerned about trade policy exposure. For Green Energy Supplier, no independently verified product families, dominant cell technology, or use-case focus could be established.

Given the available evidence, Q-Cells is the clear default recommendation for any buyer seeking transparency, long-term warranty backing, and independently verified performance data. It consistently ranks among the top three manufacturers on aggregator platforms such as SolarReviews and carries Tier 1 status that lenders and insurers will recognize. A buyer considering Green Energy Supplier should first verify whether the entity is a licensed manufacturer or a reseller, confirm who underwrites the product warranty, and request third-party test reports before proceeding.
