## Summary

Gamko New Energy is a Chinese solar panel manufacturer founded in 2008 and headquartered in Nantong, employing between 201 and 300 people and operating at an annual production capacity of 1.2 GW. LONGi Solar (LONGi Green Energy), founded in 2000, ranks among the world's largest solar module manufacturers, is publicly listed on the Shanghai Stock Exchange, employs over 37,000 people, and operates at a production capacity of 85-90 GW. LONGi holds Tier 1 bankable status from BloombergNEF - a designation Gamko does not carry - qualifying it for non-recourse project financing and giving it a well-established presence in global utility-scale project development. These differences in scale, market standing, and financial credibility represent the most fundamental distinction between the two companies.

Gamko's portfolio is notable for its exceptionally high share of bifacial modules - 81.18% of its lineup - combined with a 30-year product warranty across all panels and a peak module output of up to 750 Wp. These attributes make it a plausible option for ground-mount agri-PV or large industrial rooftop installations where bifaciality is a priority and budget constraints apply. LONGi, by contrast, leads on thermal performance and efficiency: its panels achieve a maximum module efficiency of 25%, carry an average temperature coefficient of -0.291%/°C (versus Gamko's -0.332%/°C), and offer a higher average panel power of approximately 543 Wp compared to Gamko's roughly 500 Wp. LONGi's N-type cell technology anchors a broad product range suited to residential rooftop installs, commercial and industrial (C&I) projects, and large utility-scale ground-mount deployments alike.

For international buyers selecting between the two, LONGi Solar is the stronger choice where bankability, supply chain reliability, and technical performance are non-negotiable - particularly for utility-scale and C&I financing structures. Gamko New Energy may suit buyers focused on bifacial module availability at a competitive price point for smaller residential or light commercial projects, while accepting the trade-offs of a smaller, non-Tier-1 supplier with a significantly narrower production footprint.
