Written summary
AIKO is a Chinese manufacturer headquartered in Guangzhou, founded in 2009. The company achieved BloombergNEF Tier 1 bankability status in Q3 2024 and has since expanded rapidly, reaching approximately 20 GW of annual production capacity in early 2025. AIKO is best known for its proprietary ABC (All Back Contact) cell architecture, a technology distinct from both TOPCon and HJT. Q-SUN Solar is a smaller Chinese manufacturer founded in 2014 and based in Chuzhou, Anhui province. The company reports delivering over 4 GW of modules per year to more than 50 countries and holds ISO 9001, ISO 14001, and ISO 45001 certifications, though no BloombergNEF Tier 1 designation could be confirmed in available sources. On institutional footprint, AIKO carries a significantly stronger standing.
AIKO's product lineup is oriented firmly toward premium efficiency. Its ABC modules reach confirmed module-level efficiencies above 24%, with its Neostar and INFINITE series targeting high-density residential rooftops and space-constrained commercial installations where yield per square meter commands a premium. The ABC architecture also delivers a notably low temperature coefficient of around -0.26 degrees per Celsius, which benefits installations in hot climates. Q-SUN's catalog is broader in positioning: its Mercury series uses N-type TOPCon technology with mass-production efficiency above 22.5%, while its Onyx series - a full-black, no-visible-gridline panel - targets the European residential aesthetics market. Q-SUN's cost structure is likely more accessible, making it a plausible option for budget-sensitive commercial projects.
For a typical buyer in 2025-2026, AIKO is the stronger choice when roof space is limited, maximum yield is the priority, or project financing requires Tier 1 bankability. Q-SUN is worth considering for buyers who prioritize aesthetics or a lower entry price and are comfortable with a less institutionally recognized brand. The two are not interchangeable - AIKO occupies a clear premium-technology tier, while Q-SUN competes more broadly on value.
