## Summary

Peimar is an Italian photovoltaic manufacturer founded in 2007 and headquartered in Brescia, Italy. It operates a primary production facility in Castegnato, Brescia rated at approximately 150 MW of annual capacity, alongside a secondary plant in Ningbo, China at around 300 MW. Despite its European heritage and solid market presence, Peimar does not appear on the BloombergNEF Tier 1 bankability list. Q CELLS, originally a German company founded in Bitterfeld-Wolfen, is now a subsidiary of South Korean industrial conglomerate Hanwha Group; it carries confirmed BloombergNEF Tier 1 status and operates global module production capacity reported above 11 GW per year, including major US plants in Georgia with a combined capacity of 8.4 GW. On institutional scale and lender confidence, Q CELLS holds a considerably stronger position.

Peimar focuses on European residential rooftops and small commercial systems, competing primarily on the appeal of Italian-quality manufacturing and affordable pricing. Its warranty package - 20 years on product and 30 years on linear power output - is a genuine differentiator in the mid-tier segment. Q CELLS addresses a broader range of applications, from premium residential installations to large commercial and utility-scale ground-mount projects. Its Q.ANTUM cell platform, a PERC-based technology, has long been a flagship differentiator, and the company is actively expanding into TOPCon production. Panel efficiencies across the Q CELLS lineup are generally reported between 20% and 22.5%, placing them above typical industry averages.

For most buyers in 2025, Q CELLS is the lower-risk default choice: its Tier 1 bankability, multi-gigawatt manufacturing base, and broad global installer network provide stronger warranty backstop and supply continuity. Peimar is a credible alternative for cost-conscious European buyers who prioritize domestic manufacturing provenance and are comfortable working with a smaller, non-Tier-1 supplier. The two brands are not interchangeable at the institutional level, though Peimar's product quality and warranty terms remain competitive within its own market segment.
