## Summary

Canadian Solar was founded in 2001 in Guelph, Ontario by Dr. Shawn Qu and has been listed on NASDAQ (CSIQ) since 2006, having shipped close to 180 GW of modules cumulatively with module manufacturing capacity reported around 50 GW annually. The company appears on BloombergNEF Tier 1 bankability lists and was named to S&P Global Commodity Insights' Premier List of Tier 1 Cleantech Companies for both 2025 and 2026, reflecting strong financial standing and project bankability. Ocean Solar, by contrast, is a much smaller Chinese manufacturer headquartered in Changzhou, Jiangsu Province, founded in 2012, with one plant reporting roughly 1 GW of annual capacity - a scale far below global tier-1 players, and no confirmed Tier 1 listing was found in available sources. On institutional footprint and track record, Canadian Solar is clearly the stronger of the two.

Both manufacturers focus primarily on monocrystalline modules, but Canadian Solar's lineup spans residential PERC-based HiKu6 panels, higher-efficiency TOPCon-based TOPHiKu6 panels for space-constrained roofs, and bifacial TOPBiHiKu6/TOPBiHiKu7 modules built for commercial and utility-scale ground-mount projects. Ocean Solar's catalog centers on PERC and N-type TOPCon panels in the 400-750W range, largely sold through OEM/ODM channels to installers and distributors, typically backed by 15-year product warranties and up to 30-year linear performance warranties.

For a typical international buyer, Canadian Solar is the safer default choice given its confirmed bankability, long operating history, and established warranty support network across multiple continents. Ocean Solar may suit smaller OEM-driven or price-sensitive projects, but its limited production scale and unverified tier-1 status mean buyers should perform closer due diligence before committing to large or long-term installations.
