## Summary

Q-Cells, now operating as Hanwha Q CELLS, began as a German photovoltaic pioneer before being acquired by South Korea's Hanwha Group. It holds confirmed BloombergNEF Tier 1 bankability status and operates at a global module production scale of roughly 11 GW per year, with 8.4 GW of that capacity located in Dalton and Cartersville, Georgia - making it the largest solar manufacturer in the Western Hemisphere. Suniva is a fully American company, founded in 2007 as a spinout of Georgia Tech's photovoltaics research center. After filing for bankruptcy in 2017 and emerging under new ownership in 2019, Suniva restarted domestic cell manufacturing in Norcross, Georgia in 2024 at an initial capacity of around 1 GW, with plans for a larger facility in South Carolina. No BloombergNEF Tier 1 designation for Suniva was found in available sources. On institutional scale and financial track record, Q-Cells holds a substantially stronger position.

Q-Cells' current flagship lines - such as the Q.TRON G2, built on its proprietary Q.ANTUM NEO cell platform - target premium residential rooftops and mid-size commercial installations, with confirmed module efficiencies above 22.5%. The brand also serves utility-scale developers through its broader portfolio. Suniva's restarted product line centers on high-efficiency monocrystalline cells, with cell-level efficiencies reported above 23%, and the company is developing PERC production lines in collaboration with ISC Konstanz. Its modules incorporate more than 80 percent US-made content, qualifying them for Buy America procurement programs - a meaningful differentiator for federally funded projects.

For a typical residential or commercial buyer in 2025, Q-Cells is the lower-risk default choice, given its established warranties, broad installer network, Tier 1 bankability, and proven manufacturing scale. Suniva is a compelling option specifically for buyers who require domestic content compliance or want to support a recovering US supply chain, but its institutional track record is still being rebuilt after the bankruptcy period.
