Written summary
Gamko New Energy is a Chinese manufacturer (Nantong Gamko New Energy Co., Ltd.) with an estimated annual production capacity of around 1.2 GW as of 2023. Its modules carry IEC 61215 and IEC 61730 certification and go through a three-stage quality control process including EL testing and flash testing, but no independent confirmation of BloombergNEF Tier 1 status was found, which weakens its bankability profile for lenders and large financed projects. Luxen Solar Energy, founded in Spain in 2005 and now operating with headquarters in Vienna and manufacturing in China, is recognized as an established Tier 1 supplier by BloombergNEF, with roughly 3 GW of current capacity that the company plans to expand toward 10 GW by 2026 through a new Industry 4.0 smart factory. On institutional footprint and financing credibility, Luxen clearly has the stronger track record.
Gamko's catalog centers on PERC and TOPCon modules with claimed efficiencies up to around 24 percent, spanning polycrystalline panels through larger 182N and 210N format modules, and is generally positioned toward price-sensitive buyers and smaller residential or light commercial rooftop projects. Luxen, by contrast, has been expanding its N-type TOPCon lineup with the 182 mm N5 series and 210 mm N6 series, offered in standard, all-black, and dual-glass configurations, backed by product warranties up to 20 years and performance guarantees up to 30 years, and marketed across residential, commercial and industrial, and utility-scale applications.
For a typical international buyer, Luxen Solar Energy is the safer default choice thanks to its confirmed Tier 1 status, longer operating history, and larger production scale, which simplifies financing and insurance for a project. Gamko New Energy can be a reasonable option for smaller, less risk-sensitive, budget-driven installations, but buyers should perform closer supplier due diligence before committing to larger-scale procurement.
