The initials appear in product catalogs only as a module-series prefix associated with Adani Solar's PERC line, but no independent company trading under the brand name ASM could be confirmed. For that reason, a full head-to-head comparison is not possible, and the profile below concentrates on what research could verify. Q-SUN Solar is a Chinese manufacturer founded in 2014, headquartered in Chuzhou, Anhui province, with its international marketing center in Nanjing. The company reports roughly 8 GW of annual module output across four production centers and supplies customers in more than 50 countries. Its facilities hold ISO 9001, ISO 14001, and ISO 45001 certifications, and its manufacturing processes carry TUV Germany approval under IEC standards. No confirmed placement on the BloombergNEF Tier 1 bankability list was found in current public sources, which is a meaningful gap for project-finance contexts. On institutional footprint alone, Q-SUN Solar has a clearer public record than ASM. Q-SUN Solar's current flagship range is the Mercury Series, an N-type TOPCon line covering residential, commercial, and utility segments, with higher-wattage bifacial double-glass variants suited to ground-mount projects. The company also produces PERC modules in its older portfolio. Its claimed mass-production cell efficiency exceeds 22.5 percent for the TOPCon line, with first-year degradation below 1 percent and annual linear degradation below 0.4 percent. For a buyer in 2025, Q-SUN Solar is a credible mid-tier Chinese supplier with verifiable certifications and a sizable production base, but the absence of a confirmed Tier 1 rating means additional due diligence is warranted before committing to large financed installations. ASM cannot be recommended or assessed without a verifiable brand identity. \---LINKS--- \- https://www.enfsolar.com/q-sun-solar \| Q-SUN Anhui Co. company profile - ENF Solar directory \| review \- https://www.enfsolar.com/pv/panel-datasheet/crystalline/52439 \| Q-SUN QNHT-02 N-type 600-620W module datasheet - ENF Solar \| review \- https://energypal.com/best-solar-panels-for-homes/q-sun \| Q-SUN Solar buyer overview - EnergyPal \| review Sources: \- \[Q-SUN Anhui Co., Ltd - ENF Solar\](https://www.enfsolar.com/q-sun-solar) \- \[Q-SUN QNHT-02 N-type datasheet - ENF Solar\](https://www.enfsolar.com/pv/panel-datasheet/crystalline/52439) \- \[Q-SUN Solar - EnergyPal\](https://energypal.com/best-solar-panels-for-homes/q-sun) \- \[ASM-7-PERC-350 by Adani Solar - SolarHub\](http://www.solarhub.com/product-catalog/pv-modules/63034-ASM-7-PERC-350-Adani-Solar) Written by claude-sonnet from the figures above. ## Other comparisons - [ASM vs A.B.
