## Summary

Canadian Solar is a Canadian-founded company (headquartered in Guelph, Ontario) that has been manufacturing solar panels since 2001 and has grown into one of the largest module producers in the world. It is publicly listed on NASDAQ and holds confirmed Tier 1 status, appearing on S&P Global Commodity Insights' Premier List of Tier 1 Cleantech Companies for 2025. Its nameplate module capacity reached approximately 59 GW annually as of mid-2025, placing it firmly among the handful of manufacturers operating at genuine utility scale. Corab, by contrast, is a Polish company founded in 1991 and headquartered in Olsztyn, acquired by MS Galleon in late 2024. It is primarily known as a manufacturer of photovoltaic mounting structures and balance-of-system components, with solar modules sold under the Corab Encor brand produced to its specifications rather than in a vertically integrated factory. With roughly 300 employees and exports to around 20 countries, Corab operates at a regional European scale with no presence on standard Tier 1 or BloombergNEF bankability lists. Canadian Solar has the far stronger institutional footprint.

Canadian Solar offers a broad product portfolio spanning residential, commercial, and utility-scale segments. Its current lines include the TOPHiKu6 and TOPBiHiKu7 for high-efficiency N-type TOPCon applications, the HiHero series based on HJT cell technology reaching module efficiencies around 23.9%, and more affordable PERC-based lines for cost-sensitive projects. SolarReviews ranked it the top solar panel brand of 2025, citing its combination of reliability and competitive pricing averaging near $2.96 per watt for residential installs. Corab's Encor modules, such as the bifacial double-glass EC415M at 415 W, also use N-type TOPCon cells and carry a 12-year product warranty alongside a 25-year linear performance warranty. They are positioned as a value proposition for European residential and commercial rooftop installers who already work with Corab's mounting systems.

For most buyers in 2025 - especially outside central Europe - Canadian Solar is the clearer default. Its scale, third-party bankability ratings, global installer network, and diverse product families make it suitable for projects of any size. Corab Encor panels may be a reasonable choice within Europe for installers who source mounting hardware from Corab and benefit from consolidated supply and support, but the brand lacks the independent audit trail and global after-sales infrastructure that larger project financiers typically require.
