## Summary

Gamko New Energy is a Chinese module manufacturer headquartered in Nantong, Jiangsu province, with production roots going back to roughly 2008 and a reported annual manufacturing capacity of around 1.2 GW as of 2023. The company holds standard industry certifications including IEC 61215 and IEC 61730, and markets panels across a wide wattage range - from small off-grid modules up to large-format bifacial units exceeding 700 W. No independent BloombergNEF Tier 1 bankability designation has been confirmed for Gamko in publicly available sources, which positions it as a second-tier supplier by the standards most institutional lenders and EPC contractors apply. Seraphim - formally Jiangsu Seraphim Solar System Co., Ltd., headquartered in Changzhou - was founded in 2011 and had grown to a reported 13 GW of annual manufacturing capacity by 2024, with close to 30 GW of cumulative installations across more than 100 countries. Seraphim has held BloombergNEF Tier 1 status for ten consecutive years since 2015 and has been recognized as a PVEL Top Performer on five occasions, giving it a significantly stronger institutional footprint than Gamko.

In terms of product portfolio, Gamko covers the full wattage spectrum from residential rooftop panels to high-power bifacial modules using PERC and TOPCon cell technology, and also supplies flexible modules suited to niche applications. Seraphim's current lineup centers on its TOPCon-based Sable series - reaching module efficiency of around 22.95 percent - and its HJT Hydra series pushing efficiency to approximately 23.18 percent. Both ranges are designed to serve residential rooftop, commercial and industrial (C&I), and utility-scale ground-mount segments. Seraphim's consistent presence at major trade events such as SNEC and its broad distribution agreements across Europe, Brazil, and Asia signal a more mature go-to-market operation.

For a typical international buyer - whether a residential installer seeking bankable warranties, a C&I developer requiring project financing, or a utility-scale EPC looking for lender-approved modules - Seraphim is the more defensible default choice, backed by a decade of verified Tier 1 status and a large global footprint. Buyers outside major markets should nonetheless verify local after-sales support, as warranty service limitations have been reported in certain regions. Gamko may appeal in price-sensitive, off-grid, or smaller self-funded installations where third-party bankability is not a contractual requirement, but independent long-term performance data for the brand remains limited.
