## Summary

Q-Cells, now operating as Hanwha Qcells under South Korea's Hanwha Group, traces its roots to a German manufacturer founded in Bitterfeld-Wolfen in the late 1990s. It holds Bloomberg NEF Tier 1 bankability status and, as of 2025, anticipates total module shipments exceeding 9 GW annually, supported by a large U.S. manufacturing base in Georgia that combines more than 8 GW of domestic module production capacity. Tescom Solar is a Turkish manufacturer headquartered in Izmir, operating under Tescom A.S., a company originally established in 1980 for power electronics and UPS systems that later expanded into photovoltaic modules. Tescom holds ISO 9001 and 14001 certifications and carries TSE and CE marks, but no Bloomberg NEF Tier 1 designation was found in available sources. On institutional footprint alone, Q-Cells is significantly the larger and more bankable entity at the global level.

Hanwha Qcells currently leads with its Q.TRON line, which uses N-type TOPCon cell architecture under the company's Q.ANTUM NEO platform, reaching efficiencies up to roughly 22.5% and targeting premium residential rooftops as well as light commercial installations. Earlier PERC-based Q.PEAK modules remain available for cost-sensitive commercial projects. Tescom Solar's confirmed catalog spans standard mono and polycrystalline modules in the 275-315 Wp range alongside a higher-output PERC line reaching up to 550 Wp, positioning the brand primarily for residential and small commercial projects in Turkey and neighboring markets. No independent confirmation of TOPCon or HJT adoption by Tescom was found in available sources.

For a buyer outside Turkey or the wider Turkish distribution network in 2025, Hanwha Qcells is the more practical default: its Tier 1 status supports project financing, its U.S. domestic-content modules qualify for applicable incentives, and its global service infrastructure makes long-term warranty claims more straightforward. Tescom Solar is a credible regional choice for buyers within its distribution footprint who prioritize local support, but its limited international track record makes it a harder sell in markets where bankability documentation is required by lenders or EPCs.
