## Summary

Canadian Solar is a Canadian-founded company, incorporated in Ontario in 2001 and publicly listed on NASDAQ since 2006, that has grown into one of the five largest solar module manufacturers in the world. It carries confirmed Tier 1 bankability status - appearing on the S&P Global Commodity Insights Premier List of Tier 1 Cleantech Companies in 2025 - and reported module production capacity exceeding 50 GW per year as of late 2025. Zun Power, operating under the GMA Solar brand, is a Montreal-based manufacturer that positions itself as the only solar PV module maker in Quebec. No Tier 1 or BloombergNEF bankability listing for Zun Power emerged from available sources, and its production scale appears to be that of a small regional supplier rather than a global volume player. Canadian Solar has a substantially larger institutional footprint by every measurable dimension.

Canadian Solar's current product lineup spans several distinct families. The HiKu6 and TOPHiKu6 lines target residential rooftops, with the TOPHiKu6 using confirmed N-type TOPCon cell technology, reaching efficiencies up to 23%, and carrying a 30-year performance warranty. The larger-format HiKu7 and TOPBiHiKu7 series - the latter a bifacial TOPCon module rated above 700W - are aimed at commercial and utility-scale ground-mount projects. Zun Power's GMA Solar range spans a wide wattage band from small off-grid panels to modules around 420-670W, with the company claiming PERC, TOPCon, and bifacial variants suited to commercial, agricultural, RV, and off-grid uses. Independent performance data and installer reviews for Zun Power are scarce in major industry media.

For most buyers in 2025 - whether residential, commercial, or utility - Canadian Solar is the stronger default choice, backed by decades of documented bankability, a mature global supply chain, and well-reviewed product lines at competitive pricing. Zun Power may appeal to Canadian buyers who specifically want domestically assembled panels or need a local supplier relationship, but its lack of verifiable Tier 1 status and limited third-party review coverage make direct performance comparison difficult.
