## Summary

DAH Solar and Gamko New Energy are both Chinese solar module manufacturers, but they occupy markedly different positions in the global market. DAH Solar was founded in 2009, employs over 2,000 people, and has built a production capacity of 10 GW, placing it firmly among large-scale tier manufacturers. The company holds BloombergNEF Tier 1 status - confirmed across multiple quarters through 2025 - and distributes products to over 120 countries, with Europe and Latin America as its primary export markets. Gamko New Energy was founded a year earlier in 2008 and is headquartered in Nantong, but operates at a substantially smaller scale with 201-300 employees and a production capacity of 1.2 GW. Gamko does not appear on the BNEF Tier 1 list, positioning it as a niche mid-tier supplier rather than a broadly bankable global player.

DAH Solar's portfolio of 363 panel models is anchored by TOPCon technology, which accounts for nearly 80% of its lineup and delivers an average module efficiency of 22.1% with maximum output reaching 725 Wp. The company's patented Full-Screen frameless module design differentiates it in residential rooftop and commercial C&I installations where aesthetics and reduced dust accumulation are priorities. With 87% of its catalog being bifacial, DAH Solar is equally well-suited for utility-scale ground-mount projects where rear-side energy gain is a meaningful contributor to overall yield. Gamko New Energy's 255-panel catalog is led by PERC technology (51% of models), though it also includes TOPCon variants. Its standout specification is a maximum recorded module efficiency of 24.14% - higher than DAH Solar's maximum - and it offers a full 30-year product warranty across its range. However, Gamko's average temperature coefficient of Pmax (-0.332%/°C versus -0.299%/°C for DAH Solar) signals greater power sensitivity to heat, a relevant consideration for warm-climate deployments or south-facing rooftops during peak summer conditions.

For international buyers selecting between the two, DAH Solar is the lower-risk choice wherever project financing, bankability, or long-term supply reliability are required - its Tier 1 certification, 10 GW scale, and established European distribution network make it suitable for residential, C&I, and utility-scale projects alike. Gamko New Energy can serve cost-sensitive buyers or smaller-volume orders where a competitive unit price justifies accepting a less-established supplier profile, but the absence of Tier 1 status and limited independent performance data mean that due diligence on supply continuity and after-sales support is especially important before committing to significant volumes.
