## Summary

DMEGC is a Chinese manufacturer headquartered in Dongyang, Zhejiang, with roots in the broader DMEGC group dating back to 1980. Its solar division has held BloombergNEF Tier 1 module manufacturer status for at least six consecutive years and, in early 2025, was upgraded to an "A" rating in the PV ModuleTech Bankability Report - a recognition shared by only a handful of peers. Wood Mackenzie's 2025 global module shipment rankings placed DMEGC fifth worldwide, and the company reported full-year 2025 PV shipments of roughly 24.9 GW, a 45 percent increase over 2024, against a total module production capacity of around 21 GW. Solarspace, founded in 2011 and headquartered in Xuzhou, Jiangsu, has built a different profile: it is primarily a cell powerhouse, with more than 30 GW of cell capacity across six manufacturing bases in China, Cambodia and Laos, and a much smaller module footprint of approximately 5 GW. PV InfoLink ranked it second globally in cell shipments in H1 2025. Both carry BNEF Tier 1 module status, but DMEGC has the deeper module-level institutional track record.

On the product side, DMEGC's commercial focus is firmly on modules, and its Infinity RT series uses N-type TOPCon cells. The line targets European residential and commercial rooftop installers who need bankable modules backed by a 25-year product warranty and 30-year performance guarantee, and the company is the only Tier 1 manufacturer to hold Germany's DIBt certification for overhead installation - a niche but meaningful credential for carport and pergola applications. Solarspace's module catalog spans both PERC and N-type TOPCon formats, ranging from roughly 400 W to 720 W, which suits everything from mid-market residential to utility-scale ground mounts. The company also received PVEL's Top Performance Module designation, adding an independent quality data point. Because Solarspace's core business remains cell supply rather than module brand-building, its distribution network and installer support infrastructure are generally thinner than DMEGC's in key Western markets.

For a buyer sourcing modules through a European or Australian installer channel in 2025, DMEGC is the more straightforward choice: broader bankability recognition, a mature module warranty framework, and growing distributor support. Solarspace is a compelling option for developers and EPC contractors comfortable sourcing directly and who want access to a wide wattage range at competitive cell-backed pricing - but buyers should verify local after-sales coverage before committing to large orders.
