The company reports a global production capacity of about 13 GW annually, with manufacturing bases in China and South Africa, and has shipped more than 25 GW of modules to over 100 countries. Suntech, founded in 2001 by Shi Zhengrong, was once one of the world's largest PV shipment leaders but went through a well documented 2013 bankruptcy restructuring, and as of 2025 its Wuxi unit is again in a pre-restructuring process under Chinese court oversight, even though it still formally carries Tier 1 status. On institutional footing and corporate continuity, Seraphim currently looks steadier. Both brands center their current lineups on N-type TOPCon cells and cover a broad power range - Seraphim roughly 400W to 730W, Suntech 395W to 720W - offered in bifacial and all-black variants suited to residential rooftops as well as commercial and utility-scale ground-mount projects. Seraphim markets dual-glass series such as Nebula and Sable aimed at utility-scale deployments, while Suntech's compact Ultra V Mini/Pro modules are pitched specifically at pitched residential roofs, with average efficiency around 22 percent and a notably long 29-year performance warranty, though its standard product warranty of 12 years trails some premium peers. For a typical international buyer, Seraphim is the more comfortable default given its longer unbroken bankability record and absence of active corporate distress, whereas anyone considering Suntech should verify the manufacturer's current legal and warranty standing before committing to a large project, even though the underlying panel technology and specifications of the two brands are largely comparable.
