Written summary
Seraphim, formally Jiangsu Seraphim Solar System Co., Ltd., is a Chinese module manufacturer headquartered in Changzhou that has operated since 2011 and has held BloombergNEF Tier 1 bankable manufacturer status for eleven consecutive years, with global production capacity of roughly 12-13 GW spread across five factories in China and one in South Africa. Talesun Solar, a subsidiary of Jiangsu Zhongli Group based in Changshu near Suzhou, was founded a year earlier in 2010 and also appears on BloombergNEF's current Tier 1 list, citing comparable annual capacity near 13 GW and cumulative module shipments reported around 36 GW. Institutionally the two are closely matched, though Talesun can point to a somewhat longer shipment track record and slightly larger cumulative volume.
Both brands center their current lineups on bifacial N-type TOPCon modules built with half-cut cells, offered in full-black glass-glass designs for residential rooftops as well as high-voltage 1500V dual-glass variants aimed at commercial and utility-scale ground-mount projects. Seraphim markets its Sable and Nebula series in the roughly 440-595 W range, while Talesun's BIPRO and TM3G/TM7G series extend up to 620 W, with both companies emphasizing low LID/LeTID degradation and rear-side bifacial energy gain as selling points for C&I and utility buyers alongside homeowners.
For a typical international buyer, Seraphim and Talesun are largely interchangeable: both carry current Tier 1 bankability, similar production scale, and overlapping TOPCon bifacial product portfolios. The practical deciding factors are local distributor support, warranty servicing in the buyer's region, and per-watt pricing on the specific model in question, rather than any structural advantage of one manufacturer over the other.
