## Summary

Q-SUN Solar is a Chinese manufacturer founded in 2014, headquartered in Chuzhou, Anhui Province, with its international marketing center in Nanjing. The company operates production facilities across China (Tianchang, Yancheng) and has expanded internationally to Oman and Bulgaria. It reports annual module output in the range of 4 GW or above, giving it a meaningful mid-tier footprint in global PV supply. Q-SUN holds ISO 9001, ISO 14001, and ISO 45001 certifications, and its manufacturing processes carry TUV Germany approval under IEC standards. However, no explicit BloombergNEF Tier 1 bankability classification was confirmed through available sources as of mid-2026. A.B. Energy did not surface in any credible industry database, analyst report, or independent review consulted for this comparison, which strongly suggests it is either a very small regional brand, a recently incorporated entity, or operates under a different trade name in major markets. On institutional footprint, Q-SUN Solar holds the clearer advantage by a wide margin.

Q-SUN Solar's current lineup centers on its Mercury Series, an N-type TOPCon product line covering outputs from roughly 400 W to 720 W in mono-facial, bifacial transparent-backsheet, and bifacial double-glass configurations. The company also offers the Onyx Series, a full-black aesthetic module aimed at residential rooftops, and has announced mass production of 0BB (zero busbar) technology. These products span utility-scale ground mounts, commercial rooftops, and premium residential applications. Because no verified product information is available for A.B. Energy, no equivalent technology or use-case breakdown can be offered without risk of misrepresentation.

For a typical buyer in 2025-2026, Q-SUN Solar is the more documentable choice between the two: it has verifiable production scale, confirmed certifications, and an established TOPCon roadmap. A.B. Energy cannot be recommended or dismissed on merit until independent sourcing confirms its existence and product specifications. Buyers should request certified datasheets and third-party test results directly from A.B. Energy before any procurement decision.
