Hanersun vs Seraphim - solar panel manufacturer comparison

Hanersun is a Chinese manufacturer headquartered in Nanjing, founded in 2004 (formerly known as Csunpower), and has been recognized on Tier 1 PV module bankability rankings on the strength of its high-wattage 600 W+ and 700 W+ TOPCon technology. Its annual production capacity is reported at around 5 GW, with cumulative shipments exceeding 12-16 GW across roughly 90 countries. Seraphim, also Chinese, was founded in 2011 in Changzhou (as Jiangsu Seraphim Solar System Co., Ltd.) and has held BloombergNEF Tier 1 status for eleven consecutive years, a notably longer and more consistently documented bankability track record. Seraphim operates six manufacturing bases, including one in South Africa, with total capacity around 13 GW and roughly 30 GW installed worldwide by the end of 2023. On institutional footprint, Seraphim currently presents the stronger and more independently verified position, given its longer Tier 1 tenure and larger, more geographically diversified manufacturing base, though Hanersun has been closing the gap through rapid technology-led growth.

Both companies center their product lines on N-type TOPCon cells, though Seraphim's portfolio still blends TOPCon (about 49%), PERC (about 44%) and a small share of HJT modules, giving it a wider spread across budget and premium segments, including bifacial dual-glass Nebula-series modules for both residential and utility-scale ground-mount use. Hanersun has pushed more aggressively into high-wattage TOPCon modules (up to 705 W) with a reported bifacial share near 40% of its lineup, positioning it toward higher-output residential and commercial rooftops as well as project deployments in Asia-Pacific. Reported panel efficiencies for both brands sit in a comparable 20-22.7% range, and warranty terms are broadly similar, with Seraphim typically offering 15-year product and 25-30-year linear performance warranties.

For a typical 2025 buyer, the two brands are largely interchangeable on paper, but Seraphim's longer and more consistently documented Tier 1 status makes it the somewhat safer default for financed or utility-scale projects where bankability matters most, while Hanersun can be an attractive choice for buyers prioritizing very high-wattage modules for space-constrained rooftops. Buyers should still confirm local warranty support and distributor presence for either brand, as some reviews flag inconsistent after-sales service outside China for smaller Tier 1 entrants.
