## Summary

LONGi Solar is a Chinese manufacturer headquartered in Xi'an, founded in 2000, and widely ranked among the world's largest solar module producers. The company holds BloombergNEF "Double Tier 1" status - recognized for both module and storage bankability - and reported total shipments exceeding 63 GW in the first nine months of 2025, a scale that very few rivals approach. That combination of volume and financial recognition gives LONGi one of the strongest institutional footprints in the global solar market.

Sunpro Power - formally Zhejiang Sunpro Power Technology Co., Ltd. - is a Chinese manufacturer based in Zhejiang province, founded in 2008. Smaller in overall output, it nonetheless has maintained BloombergNEF Tier 1 status for five consecutive years through Q1 2026 and has grown its capacity meaningfully in recent years. The company operates a "1+2" manufacturing layout, with its core factory in Zhejiang and overseas production lines in Poland and Indonesia, which offers a partial hedge against single-country supply risk for buyers in Europe or Southeast Asia.

LONGi's current flagship line, the Hi-MO X6 series, uses proprietary HPBC (Hybrid Passivated Back Contact) cell technology - a busbar-free design that increases light absorption - and targets premium residential rooftops and commercial installations where high power density is a priority. Sunpro Power covers a broader technology mix including TOPCon, HJT, and back-contact cells, making its catalog suited to a wider range of applications from budget commercial rooftops to high-efficiency residential systems. For most buyers in 2025, LONGi is the stronger default choice given its production scale, longer track record, and deeper bankability credentials; Sunpro Power is a credible Tier 1 alternative, particularly for buyers in markets served by its overseas facilities who also value technology diversity in their sourcing.
