## Summary

Q-Cells, formally Hanwha Qcells, was founded in 1999 in Germany and has been owned since 2012 by the South Korean conglomerate Hanwha, with corporate headquarters in Seoul. The company runs a global annual production capacity exceeding 11 GW, including a large module plant in Dalton, Georgia, and holds Top Tier bankability status in BloombergNEF's rankings, making it one of the more financially trusted names for utility-scale project financing. Resun Solar is a Chinese manufacturer based in Changzhou, Jiangsu province, founded between 2005 and 2007, operating at a much smaller scale with reported annual capacity in the 1-5 GW range, and it does not appear on published Tier 1 bankability lists. On institutional footing, Q-Cells is clearly the stronger of the two.

Q-Cells focuses primarily on residential and commercial rooftop segments through its Q.TRON line, built on n-type TOPCon cells with proprietary Q.ANTUM NEO technology, typically rated around 430-440 W with efficiency up to roughly 22.5 percent and backed by a 25-year product warranty. Resun Solar has likewise added TOPCon modules (up to around 580-590 W) alongside older mono- and polycrystalline lines, targeting both single-family homes and smaller commercial installations, with certifications including TUV, IEC61215 and IEC61730 and a stated performance warranty of up to 30 years.

For a typical buyer, particularly one relying on bank financing or subsidies that require bankable equipment, Q-Cells remains the safer default given its documented financial stability and long service history in Western markets. Resun Solar can be a reasonable lower-cost option for smaller residential jobs, but installers and buyers should verify warranty backing and supply continuity more carefully, since the brand lacks a comparable bankability track record.
