## Summary

Canadian Solar is a Canadian manufacturer headquartered in Guelph, Ontario, with more than two decades of operating history and confirmed Tier 1 status on S&P Global Commodity Insights' Premier Cleantech Companies lists for both 2025 and 2026. The company reports roughly 61 GW of annual production capacity and has shipped nearly 165 GW of modules worldwide to date, giving it one of the broadest global footprints in the industry alongside a sizeable energy storage business through its e-STORAGE subsidiary. SunLink PV, a Chinese manufacturer founded in 2004, operates on a much smaller scale, with over 10 GW of cumulative installed capacity across more than 60 countries and a record 5 GW produced in 2024 alone; it also holds BloombergNEF Tier 1 status as of Q1 2025. In terms of institutional footprint and production scale, Canadian Solar clearly outweighs SunLink PV.

Canadian Solar's lineup spans the TOPHiKu and TOPBiHiKu module families built on N-Type TOPCon cells for commercial and utility-scale projects, alongside older PERC-based HiKu series still sold for residential rooftops, plus newly announced HJT modules aimed at utility and C&I markets. SunLink PV has narrowed its focus mainly to N-Type TOPCon technology as well, offering bifacial modules for utility-scale ground-mount arrays and smaller-format panels for commercial and residential rooftops - a leaner catalog but technologically comparable to its larger rival.

For a typical buyer, whether residential or commercial, Canadian Solar remains the safer default given its longer track record, larger production base and stronger bankability, which tends to simplify project financing and long-term warranty support. SunLink PV can be a reasonable alternative where price competitiveness matters and the underlying cell technology is broadly similar, though buyers should weigh its shorter large-scale supply history and lower brand recognition outside its core markets.
