## Summary

Longi Solar is a Chinese manufacturer founded in 2000 and headquartered in Xi'an, and it has repeatedly confirmed its BloombergNEF Tier 1 status through 2025, most recently maintaining the designation in the Q3 and Q4 2025 lists. The company operates at a massive scale, with annual module production capacity reported in the tens of gigawatts, positioning it among the largest PV manufacturers globally. Peimar, by contrast, is a much smaller Italian manufacturer founded in 2007 and based in Brescia, with a primary production facility in Castegnato (around 150MW annual capacity) and a secondary facility in Ningbo, China (around 300MW). Peimar's Tier 1 status is less consistently documented in independent BNEF listings, and it lacks the institutional footprint, analyst coverage, and bankability record that Longi has built as a listed, large-scale global supplier.

Product-wise, Longi's catalog spans from utility-scale ground-mount modules to premium residential lines, with its Hi-MO X10 and Hi-MO 6/9 series built around HPBC (back-contact) and TOPCon cell technology, and newer HIBC modules combining heterojunction with back-contact design for high-efficiency residential rooftops. Peimar positions itself around "Made in Italy" manufacturing quality, offering monocrystalline and polycrystalline modules aimed at residential, commercial, and off-grid installations, with reported average efficiencies around 22.8% and long linear power warranties, but without the same breadth of utility-scale deployment or advanced cell-technology diversity that Longi offers.

For a typical buyer in 2025, Longi is generally the safer default where bankability, financing eligibility, and large-project track record matter, given its confirmed Tier 1 status and global manufacturing scale. Peimar can be an appealing choice for buyers who specifically value European manufacturing origin and are working at residential or small commercial scale, but it is not a like-for-like substitute for Longi's institutional footprint or utility-scale credentials.
