## Summary

Canadian Solar is a Canadian manufacturer founded in 2001 and publicly listed on NASDAQ since 2006, giving it a long track record of financial transparency and bankability. It was named to S&P Global Commodity Insights' Tier 1 Cleantech Companies list in both 2025 and 2026, and its module production capacity stood at roughly 61 GW as of early 2025. HY SOLAR, formerly Wuxi Shangji Automation, is a Chinese manufacturer headquartered in Wuxi that has operated since 2002 across the full PV value chain - from wafers to cells to finished modules - and by 2026 reported around 21 GW of module capacity alongside 30 GW of n-type TOPCon cell capacity, with plans to expand cell output to 50 GW. In terms of institutional footprint and public-market accountability, Canadian Solar clearly has the stronger position.

Both companies now center their offerings on TOPCon cell technology. Canadian Solar serves a broad range of use cases, from residential rooftops to commercial and industrial (C&I) installations and utility-scale ground-mount plants, with product lines including the TOPBiHiKu series (up to 690 W, around 25 percent efficiency) and the HJT-based HiHero series aimed at projects needing maximum bifacial gain. HY SOLAR is pushing an aggressive n-type TOPCon roadmap, most recently unveiling its HT3.0 modules rated up to 670 W with cell efficiencies approaching 27.5 percent, though it lacks the extensive residential and utility track record that Canadian Solar has built over two decades.

For an international buyer prioritizing bankability, long-term warranty support, and a proven installed base, Canadian Solar remains the safer default choice. HY SOLAR's newer high-efficiency TOPCon modules can be attractive on technical specs and price, but buyers should vet the local distributor and warranty terms more carefully given the brand's shorter global track record.
