## Summary

Canadian Solar is a Canadian-headquartered manufacturer founded in 2001 and listed on NASDAQ since 2006, with manufacturing concentrated mainly in China. It appears on S&P Global Commodity Insights' Tier 1 list for both PV modules and battery storage systems, and its annual production capacity reached roughly 61 GW according to 2025 BloombergNEF Tier 1 data. Hanersun is a younger Chinese manufacturer headquartered in Nanjing, founded in 2015, also recognized on the BNEF Tier 1 list and awarded Top Performer status by Kiwa PVEL, but its scale - cumulative shipments surpassing 16 GW by the end of 2025 - is noticeably smaller than Canadian Solar's, which holds a clearly stronger institutional footprint and longer track record in the industry.

Canadian Solar's portfolio spans the HiKu and TOPHiKu lines built on PERC and N-type TOPCon cells for rooftop and commercial installations, plus bifacial TOPBiHiKu modules aimed at utility-scale ground-mount projects, topped by the premium HiHero series using HJT cells reaching up to 24.4 percent efficiency. Hanersun's lineup leans heavily on TOPCon cells (around 56 percent of its catalog) alongside PERC (44 percent), with bifacial panels making up roughly 40 percent of the range, in power classes from 385W to 705W - suitable for both residential rooftops and ground-mounted commercial arrays, backed by an average 27-year performance warranty.

For a typical international buyer, whether residential or commercial, Canadian Solar remains the safer default choice thanks to its longer operating history, larger production scale, and stronger bankability, which matters for project financing. Hanersun is nonetheless a credible technology alternative, particularly where competitively priced, modern TOPCon hardware is the priority, and the brand is steadily gaining industry recognition.
