Multiple sources describe it as a long-standing BloombergNEF Tier 1 manufacturer, with some citing eleven consecutive years on the list, though no current-quarter BNEF list was found confirming this status for 2025-2026, so the claim should be treated as plausible but not independently verified. Solarspace, also China-based with manufacturing spread across China, Cambodia and Laos, is more clearly documented on BNEF's Tier 1 list, having first appeared in Q2 2023 and rejoined in Q2 2024 after BNEF tightened its bank-financing criteria, with a vicoexport tracker placing it around 10 GW of module capacity in a 2026 quarterly ranking; the company has also claimed a very large cell production base of around 30-60 GW. Of the two, Solarspace currently has more verifiable third-party confirmation of active Tier 1 bankability status, while Seraphim's institutional footprint rests more on its longer operating history and self-reported industry awards such as PVEL Top Performer recognitions. In terms of product lines, Seraphim markets distinct families including its TOPCon-based Sable and Nebula series and an HJT-based Hydra series, with flagship modules around 580-590W and mass-production efficiency near 22.5 percent, positioning it across both residential and commercial rooftop segments as well as utility-scale TOPCon deployments. Solarspace's catalog, as seen through reseller listings, spans PERC modules in the 400-410W range alongside newer n-type TOPCon bifacial modules reaching 585-595W, suggesting a similar dual-track strategy of legacy PERC for budget-conscious buyers and TOPCon bifacial for higher-yield commercial and utility projects. Neither brand shows strong evidence of HJT dominance at Solarspace, while Seraphim's Hydra line gives it a slightly more diversified cell-technology portfolio. For a typical 2025-2026 buyer, the two brands are close enough in positioning - both Chinese Tier 1-adjacent manufacturers offering PERC-to-TOPCon product ranges for rooftop and commercial use - that the choice often comes down to local distributor support and warranty servicing rather than fundamental technology differences. Seraphim's longer market presence may offer more established installer familiarity, while Solarspace's clearer recent BNEF Tier 1 confirmation may appeal to buyers prioritizing financing bankability; some reviews note warranty support inconsistencies for both brands outside their core markets, so verifying local service infrastructure before purchase is advisable regardless of brand choice. \---LINKS--- \- https://pv-tech.org/seraphim-launches-new-topcon-series-of-solar-pv-modules \| Seraphim launches new TOPCon series of solar PV modules \| article \- https://www.pv-tech.org/editors-blog/pv-talk-jun-zhunge-executive-vice-president-seraphim-solar \| PV Talk: Jun Zhuge, Executive VP, Seraphim Solar \| article \- https://pv-magazine.com/press-releases/solarspace-rejoins-bnef-tier-1-list-for-q2-2024 \| SolarSpace rejoins BNEF Tier 1 list for Q2 2024 \| article \- https://www.pv-magazine.com/?p=59659 \| SolarSpace ranked as a Tier 1 PV Module Manufacturer by BNEF \| article \- https://www.vicoexport.com/en/65510/tier-1-list-of-solar-panel-manufacturers-q1-2026/ \| Tier 1 List of Solar Panel Manufacturers Q1 2026 \| article Written by claude-sonnet-5 from the figures above. ## Other comparisons - [Seraphim vs A.B.
