## Summary

I have enough to write a grounded comparison now.

Talesun is a Chinese manufacturer founded in 2010 and headquartered in Suzhou, operating as a subsidiary of the Jiangsu Zhongli Group with manufacturing bases in China and Thailand. The company has repeatedly appeared on BloombergNEF's Tier 1 PV module maker list, most recently confirmed for 2025, and reports annual capacity in the range of roughly 7 to 10 GW of cells and modules depending on the source. Sunpro, formally Zhejiang Sunpro Power Technology, is a newer entrant founded in 2018 and based in Yuhuan and Hangzhou, Zhejiang, with additional branches in Germany, the Netherlands, Poland, the US and Brazil. Sunpro has also secured BNEF Tier 1 status, with the company citing several consecutive quarters and years on the list through 2025 and into 2026. Given its longer track record, larger production scale and older corporate lineage, Talesun currently holds the stronger institutional footprint, though Sunpro has built credible bankability relatively quickly for a company only a few years old.

Talesun's catalog centers on N-type TOPCon bifacial dual-glass modules, typically in the 435 to 620 watt range, marketed for residential, commercial and utility-scale installations, with full-black variants aimed at rooftop aesthetics. Sunpro's lineup spans a broader technology mix, including TOPCon, heterojunction (HJT) and back-contact (BC) modules with outputs from 375 to 720 watts, positioning it toward both mainstream rooftop and higher-efficiency premium segments; the company also holds a number of core patents and standard TUV, UL, CE and PID certifications. Both brands offer warranty terms in line with current industry norms, generally around 12-year product and 25-year performance coverage.

For a typical buyer in 2025, either brand should clear the basic bankability bar given their shared Tier 1 status, so the choice often comes down to specific product availability, local distributor support and pricing rather than a clear technology gap. Talesun's longer operating history and larger production base may appeal to buyers prioritizing an established supply chain, while Sunpro's broader cell technology range, including HJT and BC options, may suit buyers seeking higher-efficiency or newer-generation modules. In practice the two are close substitutes for most residential and commercial projects.
