## Summary

Canadian Solar is a Canadian manufacturer founded in 2001 by Dr. Shawn Qu, now headquartered in Kitchener, Ontario, and listed on Nasdaq under CSIQ since 2006. The company has been named to S&P Global Commodity Insights Premier List of Tier 1 Cleantech Companies for both 2025 and 2026, and its manufacturing footprint is substantial, with planned module capacity around 51 GW by the end of 2025. Sunket New Energy, by contrast, is a Chinese manufacturer based in Wuxi, founded in 2007 and backed by Delin Holding Group, operating at a much smaller scale with roughly 5 GW of annual module capacity plus about 1 GWh of energy storage production. In terms of institutional footprint and bankability, Canadian Solar is clearly the more established and globally recognized player.

Canadian Solar's current lineup centers on N-type TOPCon modules under the HiKu and TOPHiKu/TOPBiHiKu families, spanning monofacial and bifacial designs for residential, commercial and industrial (C&I), and utility-scale ground-mount projects, with efficiencies up to 24.4 percent and warranties extending to 25 years on product and 30 years on performance. Sunket New Energy has also adopted TOPCon technology alongside older PERC lines, offering panels across a wide power range from 110W to 700W with average efficiency around 21 percent and top models reaching 23 percent, holding certifications such as TUV, CE, IEC and CQC, positioning it as a smaller, export-oriented brand aimed at price-sensitive residential and commercial buyers rather than large utility developers.

For a typical buyer prioritizing long-term bankability, warranty backing, and a manufacturer with decades of track record and public financial disclosure, Canadian Solar is the safer default choice. Sunket New Energy may be worth considering for smaller-scale or budget-conscious projects, but without a confirmed BloombergNEF Tier 1 listing, it carries more uncertainty around long-term supplier stability.
