## Summary

Canadian Solar was founded in 2001 and is headquartered in Guelph, Ontario, Canada, with the majority of its manufacturing concentrated in China. The company has traded on the NASDAQ since 2006 and consistently holds Tier 1 bankability status, appearing on BloombergNEF's module rankings as well as the S&P Global Commodity Insights Premier List of Tier 1 Cleantech Companies for 2025. Its module manufacturing capacity stood at approximately 59 GW as of mid-2025, with actual shipments reaching 31.1 GW in 2024, placing it among the top global module suppliers by volume. Deye - formally Ningbo Deye Technology Co., Ltd. - is a Chinese manufacturer founded in 2007 and headquartered in Ningbo, Zhejiang; however, industry coverage consistently categorizes Deye as an inverter and energy storage system maker, not a solar module producer, and no evidence of a Deye-branded solar panel line appeared in available trade and industry sources. On institutional footprint in the solar panel market specifically, Canadian Solar holds an overwhelming advantage.

Canadian Solar's current product families center on its HiKu and TOPHiKu series, which employ TOPCon cell technology and serve residential rooftops - including an all-black aesthetic variant - as well as commercial installations and large-format utility-scale ground mounts. Deye's published catalog covers hybrid string inverters, on-grid and off-grid inverters, microinverters, and battery storage systems targeting residential, off-grid rural, and commercial/industrial applications. Its energy storage products have earned approvals such as the MOSAIC Approved Vendor List in the United States. The two brands, in other words, occupy different rungs of the solar value chain and do not compete in the same product category.

For a buyer in 2025 specifically shopping for solar modules, Deye does not offer a relevant competing product, and Canadian Solar is the default choice by default - backed by Tier 1 bankability, multi-gigawatt scale, and a product range spanning residential to utility projects. A buyer instead seeking an inverter or integrated storage system would look to Deye alongside competitors such as Sungrow or Growatt, a segment where Canadian Solar is not a primary player.
