DAH Solar vs MY Solar - solar panel manufacturer comparison

DAH Solar and MY Solar represent two significantly different tiers of the solar PV manufacturing market. DAH Solar, founded in 2009 and headquartered in Hefei, China, is an established manufacturer with over 2,000 employees and a production capacity of 10 GW. The company holds confirmed Tier 1 bankable status according to the Bloomberg NEF Q1 2025 list, making it eligible for project financing from institutional lenders. MY Solar, by contrast, is a smaller manufacturer with no disclosed founding year, employee count, or production capacity figures, and does not carry Tier 1 bankable status - a meaningful distinction for buyers who require third-party credit assurance or project finance.

On the technology side, DAH Solar's portfolio of 363 models is dominated by TOPCon cells (79.6% of models), delivering an average module efficiency of 22.1%, an average power output of 520.3 Wp, and an average temperature coefficient of -0.299%/°C. Some 87% of its lineup is bifacial, making it well suited to utility-scale ground-mount projects where albedo gain is relevant, as well as to commercial C&I and residential rooftop applications where high efficiency per square meter matters. The company also holds a patent on Full-Screen frameless module design, which reduces soiling accumulation. MY Solar's portfolio of 140 models is primarily PERC-based (57.9%), with an average efficiency of 19.87%, an average output of 417.7 Wp, and a less favorable temperature coefficient of -0.333%/°C. While MY Solar lists a peak panel at 740 Wp and 23.82% maximum efficiency - slightly ahead of DAH Solar's best - these are isolated portfolio peaks; the overall portfolio average is substantially lower. MY Solar's bifacial share stands at only 38.6%, and its average warranty period of 27.1 years trails DAH Solar's 29.4 years.

For international buyers choosing between the two, DAH Solar offers a clearly stronger proposition across most dimensions: Tier 1 bankability, higher average efficiency, a better temperature coefficient, a predominantly TOPCon and bifacial lineup, and longer warranty terms. MY Solar may serve cost-sensitive off-grid or small-scale applications where bankability requirements are absent, but for any project requiring lender approval, long-term yield assurance, or grid-scale deployment, DAH Solar is the more credible choice.
