Catalogue against catalogue
An average over a catalogue describes the range a manufacturer publishes, not the module you would buy. A brand with two flagship panels and eighty older ones averages worse than one that has retired its back catalogue.

Written summary
DMEGC is a Chinese manufacturer operating under the Hengdian Group, active in the photovoltaic and magnetic-materials business since 1980 and listed on the Shenzhen Stock Exchange. It holds confirmed Tier 1 status in BloombergNEF's rankings (reaffirmed as of Q3 2025) and an A rating in the PV ModuleTech bankability report, with annual module production capacity around 21 GW and cumulative shipments exceeding 50 GW. Resun Solar, part of Resun Group (which also runs the Restar Solar brand), was founded in 2005 and is based in the Suzhou/Changzhou area of Jiangsu province, with annual module capacity estimated at roughly 5 GW - a notably smaller scale than DMEGC. Public sources do not clearly confirm Resun Solar's presence on the BloombergNEF Tier 1 list, which, absent that confirmation, marks a meaningful gap versus DMEGC in institutional footprint and project bankability.
DMEGC's product range centers on n-type TOPCon modules, including lightweight bifacial panels designed for weight-constrained residential roofs and larger utility-scale modules (such as a 580 W bifacial and a 630 W mono-facial unit rated around 22.5 percent efficiency). Resun Solar's catalog is broader but less technologically defined, spanning poly- and mono-crystalline, double-glass, and BC-type panels from just a few watts up to 720 W, serving residential, commercial and off-grid or World Bank-backed rural electrification projects across developing markets, with TUV, CE and UL certifications.
For a typical buyer weighing a bank-financed rooftop or commercial project, DMEGC is the safer default given its confirmed Tier 1 status, larger production scale and modern TOPCon lineup. Resun Solar can be a reasonable budget-oriented option for smaller or off-grid installations, but its bankability credentials warrant closer verification before use in externally financed projects.
