## Summary

Seraphim is a Chinese solar manufacturer founded in 2011 and headquartered in Changzhou, Jiangsu. It has held Bloomberg NEF Tier 1 status for 11 consecutive years and has earned six PVEL Top Performer awards, signaling consistent manufacturing quality. The company reported approximately 12 GW in module shipments in 2024 and broke ground in 2024 on a new 10 GW factory in Guangzhou, targeting production capacity of roughly 13 GW. Tongwei, by contrast, is a far larger conglomerate founded in 1982 and based in Chengdu, Sichuan. It holds both BNEF Tier 1 status and a PV ModuleTech "A" bankability rating, and as of 2025 it operates solar cell capacity of approximately 150 GW and module capacity of roughly 90 GW, making it one of the biggest vertically integrated solar producers on the planet and a Fortune Global 500 member. On institutional scale alone, Tongwei dwarfs Seraphim.

Both companies compete across the mainstream N-type segment. Seraphim's current lineup spans TOPCon and HJT modules, with efficiencies reported up to 22.5%, and the brand is broadly positioned as a mid-tier value option for commercial rooftops and utility-scale ground mounts in markets such as Europe, Japan, and Australia. Tongwei's TW Solar range leans heavily on TOPCon technology - including its high-output TNC3.0 series reaching 770 W and 24.8% efficiency - alongside an HJT line peaking near 715 W. Tongwei modules are pitched primarily at utility developers and larger commercial projects where output density and bankability with project lenders are priorities.

For most buyers in 2025, Tongwei carries the stronger bankability narrative and more advanced high-wattage product options, making it the safer default for utility-scale or institutionally financed projects. Seraphim remains a reasonable choice for cost-conscious commercial deployments, but prospective buyers in markets such as Australia should verify current warranty-support arrangements independently before committing, given documented concerns raised by local industry reviewers.
