## Summary

AIKO is a Chinese manufacturer founded in Guangzhou and is one of the fastest-rising names in the solar industry, having achieved BloombergNEF Tier 1 status in Q3 2024 - a distinction held by fewer than 2% of the world's solar companies. The company has reported cumulative cell and module shipments exceeding 190 GW and employs more than 10,000 people globally. Peimar, by contrast, is a European niche manufacturer founded in 2007 and headquartered in Castegnato, near Brescia, Italy. Its combined annual output across Italian and Chinese factories is well under 500 MW, placing it in a substantially smaller league than AIKO in terms of institutional scale and global presence. AIKO carries the stronger footprint by a wide margin.

AIKO's defining technology is its ABC (All Back Contact) cell architecture, in which both electrical contacts are moved to the rear of the cell, eliminating front-side shading losses. Independent reviewers and installers have noted panel efficiencies averaging around 23-24%, with flagship models reportedly reaching 25%, placing AIKO near the top of the mass-production efficiency rankings worldwide. The product range targets premium residential and commercial rooftops where maximizing output per square metre justifies a higher upfront cost. Peimar's catalog covers monocrystalline products aimed at residential and light commercial segments, with efficiency figures more typical of conventional PERC-era modules in the 17-19% range. Peimar's "Made in Italy" branding and longstanding European distribution network give it appeal in markets where local manufacturing origin carries regulatory or reputational weight.

For most buyers in 2025, AIKO is the stronger default choice if peak efficiency and bankability are the primary criteria - the BloombergNEF Tier 1 rating, technology leadership in ABC cells, and installer recognition all point in that direction. Peimar remains a credible option for European procurement contexts where a verified Italian manufacturing origin or a smaller, relationship-based supplier is preferred over a high-volume Chinese exporter.
