## Summary

Gokin Solar is a Chinese manufacturer founded in 2019, focused on photovoltaic module production with an emphasis on back-contact (BC) technology. By the end of 2024, the company had scaled module production capacity to approximately 4 GW per year and entered Solarbe's 2025 global PV module shipment rankings, placing 10th in the PVBL Global Top 20 PV Brands. Q-Cells was founded in Germany in 1999, acquired by South Korea's Hanwha Group in 2012, and today operates as Hanwha Q CELLS. It holds a BloombergNEF Tier 1 rating, was named an S&P Global 2025 Tier 1 Cleantech company, and reports global module production capacity of roughly 11 GW, supplemented by a 3.3 GW factory in Cartersville, Georgia that qualifies for U.S. domestic content incentives. On institutional credibility and bankability, Q-Cells holds a clear advantage.

Gokin has concentrated its lineup on BC modules - where rear-mounted contacts eliminate front-side shading and can deliver meaningfully higher energy yield per unit area compared with standard TOPCon designs. Its 2025 portfolio covers a residential all-black series, a commercial and industrial rooftop format, and a dual-glass utility-scale version. Q-Cells targets a broader range: its Q.TRON residential line is built on TOPCon cells with rated efficiencies confirmed above 22%, while the Q.PEAK DUO series addresses cost-sensitive commercial and rooftop buyers. Q-Cells also carries a 25-year combined product and labor warranty - a benchmark that many smaller manufacturers cannot match.

For most buyers in 2025, Q-Cells is the more straightforward choice. Its Tier 1 status, long warranty, and U.S. domestic production simplify project financing and insurance underwriting. Gokin is a genuine emerging competitor whose BC technology is credible and independently noted, but its shorter operating history and narrower installer network favor buyers who have already confirmed strong local after-sales support.
