## Summary

Corab is a Polish company founded in 1991 and based in Olsztyn, Poland, with production in Bartoszyce. It began as an electronics and steel-processing business before pivoting into photovoltaics, and it has grown into one of the largest European manufacturers of PV mounting structures, ballasts and racking systems, while also distributing solar modules, inverters and storage under its own and partner brands across more than 30 countries. It was acquired by MS Galleon in December 2024. Corab does not appear on the standard BloombergNEF Tier 1 module manufacturer lists, reflecting its identity as primarily a structures and components specialist rather than a large-scale cell and panel producer. Q-Cells, formally Hanwha Q Cells, has a longer and more internationally recognized manufacturing pedigree, combining German engineering origins, Korean corporate ownership under Hanwha, and an expanding US production base, and it consistently holds Bloomberg Tier 1 bankability status, giving it the stronger institutional footprint of the two.

Corab's core product lines are built around mounting and installation infrastructure for pitched roofs, flat roofs, ground-mount and carport systems, along with trackers, making it a go-to supplier for installers who need adaptable racking hardware for varied European rooftops and ground installations rather than a single flagship module line. Q-Cells is a pure module manufacturer known for its Q.ANTUM and Q.ANTUM DUO cell technology, based on PERC architecture, delivering panels in the roughly 20 to 22.5 percent efficiency range at mid-range pricing near 0.7 to 1 dollar per watt, with 25 to 30 year performance warranties. Its panels are typically positioned for premium residential and light commercial rooftops where bankability, warranty strength and consistent performance data matter to installers and financiers.

For a typical buyer choosing panels specifically, Q-Cells is the more directly comparable and better-documented choice, given its Tier 1 status, established efficiency and warranty data, and broad installer familiarity. Corab is better understood as a complementary player, valuable when sourcing racking, mounting systems or a full European balance-of-system package rather than as a head-to-head module competitor, so the two brands are not strictly interchangeable but often coexist in the same installation.
