## Summary

Gamko New Energy (Nantong Gamko New Energy Co., Ltd.) is a Chinese solar module manufacturer headquartered in Nantong, Jiangsu Province, founded in 2017. The company produces monocrystalline and bifacial panels ranging from small off-grid modules up to 800 W, and self-reported annual manufacturing capacity reached 1.2 GW in 2023. Gamko holds certifications including IEC 61215, IEC 61730, CE, ISO 9001, and ISO 14001, but no independent BloombergNEF Tier 1 listing was found in available sources. ZNShine (ZNSHINE PV-TECH Co., Ltd.) is a considerably more established manufacturer, also based in Jiangsu Province, China. The company has appeared continuously on the BloombergNEF Tier 1 list since Q1 2015 - a status reconfirmed in Q3 2025, representing ten consecutive years of bankability recognition. With three production bases in Changzhou, Suqian, and Dali, ZNShine's combined manufacturing capacity stands at 10 GW. In terms of independently verified bankability, production scale, and market track record, ZNShine holds a substantially stronger institutional footprint.

Gamko's product portfolio spans PERC and TOPCon monocrystalline modules as well as bifacial variants, positioning the company primarily for residential rooftop installs, small commercial projects, and off-grid applications. ZNShine addresses a broader range of use cases: N-type TOPCon bifacial modules in the 570 W to 730 W range serve utility-scale ground-mount and commercial C&I rooftop projects, while lower-wattage and ultra-black ultra-low-carbon variants target residential demand. A proprietary feature of ZNShine modules is graphene-coated glass engineered for self-cleaning properties. Datasheets presented at ENEX 2025 in Poland indicate conversion efficiency up to 23.32% for the current N-type TOPCon bifacial line. ZNShine also markets HJT bifacial modules in higher power classes for large-scale projects and operates a European subsidiary with a local team, which is relevant to warranty servicing and after-sales support for buyers in Europe.

For international buyers choosing between the two, the central distinction is scale and institutional credibility. ZNShine is the clearly better-documented option for project developers requiring bankable modules for debt-financed utility-scale or C&I installations, given its decade-long Tier 1 classification and 10 GW production base. Gamko New Energy may appeal to buyers seeking competitive pricing for straightforward residential or off-grid projects where BloombergNEF Tier 1 status is not a lender requirement. For any project where bankability documentation is contractually required by lenders or EPCs, ZNShine is the more defensible selection of the two.
