## Summary

MY Solar is a Chinese manufacturer founded around 2010 and operating under the MY Solar Group umbrella, with MYPVTECH as its primary production entity. The company produces solar modules alongside inverters and energy storage systems, targeting a broad range of project types. Based on available sourcing, MY Solar does not appear on published BloombergNEF Tier 1 module lists, which places it in a lower bankability tier compared to the industry's most institutionally recognized names. Q-Cells, by contrast, traces its origins to Germany in the late 1990s and is now a flagship brand of the South Korean conglomerate Hanwha Group. Hanwha Q CELLS holds confirmed BloombergNEF Tier 1 status and was named an S&P Global 2025 Tier 1 Cleantech Company. Its combined global module production capacity has been reported at over 11 GW per year, with U.S.-based capacity in Georgia alone reaching 8.4 GW - making it the largest solar manufacturer in the Western Hemisphere by domestic output. On institutional footprint, Q-Cells is the clear leader.

In terms of product positioning, MY Solar serves primarily value-oriented commercial and small-scale utility segments with a catalog that includes standard crystalline modules and bundled balance-of-system components. Specific cell technology details for MY Solar are not readily confirmed by independent reviews. Q-Cells targets both the residential premium and utility-scale markets with two well-documented product families: the Q.ANTUM line based on PERC cell technology, and the newer Q.ANTUM NEO and QTron series built on N-type TOPCon cells. Top QTron models reach efficiency ratings around 23.7%, and the company backs all current residential panels with a 25-year product warranty covering replacement labor. The temperature coefficient for leading Q-Cells models (-0.29%/°C) outperforms the industry average, which matters in hot climates.

For a typical buyer in 2025, Q-Cells is the more defensible default - it offers independently verified performance data, strong bankability for project financing, domestic U.S. manufacturing options, and widely available installer support. MY Solar may appeal to budget-driven procurement where upfront cost is the primary constraint, but the limited third-party review coverage makes it harder to validate long-term reliability claims.
