## Summary

DMEGC is a Chinese manufacturer headquartered in Hengdian, Zhejiang province, with over 45 years of experience in magnetic materials and electronics and a solar photovoltaics division operating since 2009. The company has scaled into the top tier of global module production, shipping 13.4 GW in the first half of 2025 alone, with annual cell capacity of 23 GW and module capacity of 21 GW. It holds both Bloomberg NEF Tier 1 and S&P Global Tier 1 designations, confirming that major lending institutions are willing to finance projects built around its panels, and Wood Mackenzie ranked it fifth among all global module manufacturers in 2025. MY Solar Technology Co., Ltd. is also a China-based producer, visible on international trade platforms such as Made-in-China.com, offering monocrystalline modules across a wattage range from roughly 280 W to 700 W with standard certifications including TUV, CE, IEC, and ISO. As of mid-2025, MY Solar does not appear on any publicly available Tier 1 list, and its annual production scale and institutional backing cannot be independently verified from industry sources. On institutional footprint alone, DMEGC holds a substantially stronger position.

DMEGC's product lineup centres on N-type TOPCon technology, with the Infinity RT series serving as its flagship family. Independent testing organisations have recognised the series as a Kiwa PVEL Top Performer and RETC Overall Highest Achiever, with confirmed module efficiencies reaching up to 22.3% in third-party evaluations. The portfolio spans residential rooftop, commercial and industrial rooftop, and utility-scale ground-mount segments, and the brand carries DIBt certification for markets with strict building-authority requirements as well as VKF hail resistance certification. MY Solar's broad wattage range points toward smaller residential and mid-scale commercial applications, though no independently reviewed performance data or field-test results for its products could be confirmed through industry publications.

For most international buyers evaluating these two brands, DMEGC is the straightforward default. Its verified bankability, top-five global volume ranking, independent performance awards, and the breadth of available installer reviews provide a level of due-diligence support that MY Solar currently cannot match. MY Solar may be considered for budget-constrained off-grid or small residential projects where lender approval is not required, but for any commercial installation, financed project, or situation where long-term warranty enforcement matters, DMEGC is the more dependable choice.
