An average over a catalogue describes the range a manufacturer publishes, not the module you would buy. A brand with two flagship panels and eighty older ones averages worse than one that has retired its back catalogue.

Written summary

Q-SUN Solar is a Chinese photovoltaic manufacturer founded in 2014 and headquartered in Nanjing, Jiangsu, operating manufacturing hubs delivering more than 4 GW of modules annually to customers in over 50 countries. 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.
