AKCOME, also based in China (Jiangsu province, part of the Jiangsu Akcome Industrial Group), had a longer public profile and reached BloombergNEF Tier 1 status as recently as the second quarter of 2024, with historical module capacity cited around 9.4 GW at its peak, but the company's fortunes collapsed sharply afterward: it halted several subsidiary factories in mid-2024, was delisted from the Shenzhen Stock Exchange after its shares fell below 1 yuan for 20 consecutive trading days, and a subsidiary entered court-supervised bankruptcy reorganization in July 2024 amid the broader Chinese solar overcapacity crisis. On institutional footing, Q-SUN currently presents the steadier and more active manufacturing base, while AKCOME's Tier 1 credentials are now largely historical. Q-SUN's product lineup is built around N-type TOPCon technology, with its Onyx series offering full-black, half-cut bifacial double-glass modules aimed at aesthetic residential and commercial rooftops, and its Mercury series covering a broader wattage range for commercial and utility-scale use. AKCOME's historical catalog, prior to its 2024 troubles, also centered on N-type high-efficiency cells and covered module and cell manufacturing at scale for utility and commercial projects, but with the Changxing base and other facilities disrupted, current product availability and long-term supply continuity are far less certain than they were during its Tier 1 period. For a typical buyer in 2025, Q-SUN is the more defensible default: it has an active, functioning manufacturing operation and a current TOPCon-based product range, whereas AKCOME's bankruptcy proceedings and stock delisting raise real concerns about warranty servicing and long-term parts or replacement support, regardless of its past Tier 1 recognition. Buyers considering AKCOME should treat any residual inventory with caution and verify current operational status directly before purchase. \---LINKS--- \- https://www.pv-magazine.com/2024/06/17/akcome-halts-some-manufacturing-faces-possible-chinese-stock-delisting/ \| Akcome halts manufacturing, faces possible Chinese stock delisting \| article \- https://energynews.oedigital.com/environment/2024/07/30/chinese-solar-company-akcomes-subsidiary-declares-personal-bankruptcy-amidst-plunging-prices-overcapacity \| Akcome subsidiary declares bankruptcy amid price glut and overcapacity \| article \- https://www.energyconnects.com/news/renewables/2024/july/chinese-solar-firm-forced-into-bankruptcy-as-glut-deepens/ \| Chinese solar firm forced into bankruptcy as glut deepens \| article \- https://www.enfsolar.com/q-sun-solar \| Q-SUN Anhui Co., Ltd manufacturer profile \| article \- https://taiyangnews.info/topmodules/top-solar-modules-listing-january-2025 \| TOP Solar Modules Listing - January 2025 \| article Written by claude-sonnet-5 from the figures above. ## Other comparisons - [AKCOME vs A.B.
