DAH vs MY Solar - solar panel manufacturer comparison

DAH is a Chinese solar module manufacturer that has repeatedly appeared on BloombergNEF's Tier 1 PV module manufacturer list, including the Q1 2025 and Q4 2025 rankings, a status it has held since at least 2023. The company has invested heavily in n-type TOPCon capacity, with announced projects including a 10 GW vertically integrated plant in Shanxi and additional wafer and cell expansions in Anhui province, though exact current totals vary across reports and likely sit in the multi-gigawatt range per year. MY Solar, by contrast, operates under the Horay Solar corporate umbrella, founded around 2010 and based in Wuxi, China, with a Malaysia factory added in 2019 to serve the North American market; its reported annual capacity figures range from roughly 500 MW to 2.5 GW depending on the source, and no confirmed BloombergNEF Tier 1 listing for the brand turned up in available records. On institutional footprint, DAH clearly has the stronger and better-documented position, with consistent third-party Tier 1 recognition and larger-scale, publicly tracked manufacturing expansion.

In terms of product focus, DAH's lineup centers on n-type TOPCon bifacial glass-glass modules spanning residential, commercial and utility-scale use, including higher-wattage large-format panels (up to roughly 700 W+ in some utility-oriented series) and a "Full-Screen" rectangular-cell TOPCon line aimed at C&I and utility projects, alongside a smaller residential kit branded as a compact "Solar Unit." MY Solar's catalog, built on the same Horay Solar manufacturing base, also leans on monocrystalline and bifacial TOPCon modules, positioned more generically across residential and commercial rooftops, with warranty terms that vary noticeably between datasheets (some citing 15-year product warranties, others 30 years), suggesting a less standardized product strategy than DAH's.

For a typical buyer in 2025, DAH is the safer default choice for most installations, particularly anything requiring bank or lender financing, given its sustained, independently verified Tier 1 bankability status and larger, more consistently documented production scale. MY Solar may still be a reasonable option for smaller, cash-financed residential or commercial jobs where bankability is less critical, but buyers should independently verify warranty terms and request current certification and test data, since available information on the brand is thinner and less consistent than for DAH.
