Written summary
Gamko New Energy is a Chinese photovoltaic manufacturer headquartered in Nantong, Jiangsu province, in operation since approximately 2017. The company reported an annual module production capacity of around 1.2 GW as of 2023 and offers a broad product range spanning from compact 5 W units to modules exceeding 800 W, covering mono and polycrystalline, flexible, and bifacial configurations. Gamko holds certifications including IEC 61215, IEC 61730, ISO 9001, and CE, and markets itself as a Tier 1-quality supplier; however, independent confirmation of BloombergNEF bankability listing was not found in available industry sources. Solarspace, founded in 2011 and also based in China, operates at a substantially different scale - the company reached 60 GW of cell capacity and 7.2 GW of module capacity by end of 2023, and ranked second globally in solar cell shipments for 2024 according to PV InfoLink data. Solarspace is consistently recognized among bankable manufacturers by BloombergNEF, giving it a materially stronger institutional footprint.
Gamko New Energy positions itself across residential rooftop, small commercial, and off-grid or hybrid applications, competing primarily on price flexibility and product breadth. Its portfolio includes PERC and TOPCon-based modules, making it a usable option for installers who need accessible pricing on smaller volume orders. Solarspace focuses more intensively on N-type TOPCon bifacial modules - a technology well suited to utility-scale ground-mount and commercial C&I projects - while also supplying PERC products to cover mainstream residential demand. The company's manufacturing facility in Laos further supports supply chain diversification for export markets with trade restrictions.
For most international buyers, Solarspace is the lower-risk default: its verified top-two cell shipment ranking, confirmed bankability, and established TOPCon bifacial lineup make project financing and long-term performance warranties easier to underwrite. Gamko New Energy is not without merit for budget-sensitive or smaller-scale procurement, but buyers should independently verify its current bankability standing and warranty terms with a local distributor before committing to larger volumes.
