MY Solar vs Trina Solar - solar panel manufacturer comparison

MY Solar, operating under the MYPVTECH brand and part of MY Solar Group, is a Chinese manufacturer founded in 2010. The company produces approximately 3 GW of solar modules per year and complements its module offer with inverters, energy storage batteries, and complete solar power systems. Its customer base spans Europe, the Americas, Asia, and Africa, though no confirmed BloombergNEF Tier 1 bankability listing was found in available sources. Trina Solar, founded in 1997 in Changzhou, Jiangsu Province by Jifan Gao, ranks among the top three global module manufacturers, with cumulative shipments exceeding 205 GW and a presence in over 100 countries. The company holds confirmed BloombergNEF Tier 1 status as of Q1 2026 and reports annual production exceeding 80 GW. On institutional footprint and bankability, Trina Solar holds a decisive advantage.

MY Solar's catalog covers mono- and polycrystalline modules in the 600 W to 700 W range, certified to TUV and CE standards, serving residential rooftop and smaller commercial installations. Its bundled inverter and storage offer positions it as a one-stop system supplier, which can be practical for off-grid or small on-grid deployments where a single vendor is preferred. Trina Solar organises its lineup around the Vertex product family. The Vertex N series uses i-TOPCon Ultra cell technology and reaches up to 740 W per module, making it well suited to utility-scale ground-mount projects where maximising power density is critical. The Vertex S+ targets residential and C&I commercial rooftops at up to 22.5% module efficiency, while the budget-oriented Honey series addresses cost-sensitive buyers. Trina is also the only manufacturer to achieve a perfect score in PVEL third-party module testing, a meaningful indicator of long-term reliability.

For most international buyers, Trina Solar is the stronger default choice given its proven bankability, manufacturing scale, and depth of product range across all market segments. MY Solar may suit buyers seeking a competitively priced bundled system for residential or off-grid use where project financing and Tier 1 status are not a requirement. The two brands are not interchangeable in terms of institutional credibility or addressable scale.
