## Summary

Canadian Solar was founded in 2001 by Dr. Shawn Qu and is headquartered in Guelph, Ontario, with the bulk of its manufacturing located in China. The company is publicly listed on NASDAQ and has maintained a consistent presence on the BloombergNEF Tier 1 bankability list, meaning that independent lenders have repeatedly financed projects using its modules on a non-recourse basis - a strong institutional endorsement. Its planned module production capacity was targeting over 51 GW by the end of 2025, placing it firmly among the top five solar manufacturers globally. JS Solar, operating as Yixing JS Solar Co., Ltd., was established in 2004 and is headquartered in Yixing, Jiangsu Province, China. The company claims a production capacity of up to 20 GW and states that it exports to more than 100 countries, with distribution partners in the EU, South Asia, and Latin America. However, JS Solar does not appear in the available BloombergNEF Tier 1 lists, which means its bankability standing is substantially less established than Canadian Solar's.

Canadian Solar's product portfolio spans residential rooftop, commercial and industrial, and utility-scale ground-mount applications. Its TOPCon 3.0 modules - confirmed by the company and covered in industry press - achieve up to 670 W output and 24.8% efficiency, while its Low Carbon HJT series reaches up to 660 Wp at 24.4% module efficiency. These are well-documented, commercially available products entering mass shipment in 2025 and 2026. JS Solar's product range is generally described as covering a broad set of solar applications, but independent technical reviews of specific module families are scarce, and confirmed cell technology details for current series are not readily available from credible industry sources.

For most international buyers - particularly those working on financed utility or C&I projects - Canadian Solar is the safer default: its Tier 1 status, public financial disclosure, and global service network reduce counterparty and warranty risk considerably. JS Solar may represent a cost-competitive option for buyers with strong local distributor relationships and shorter payback horizons, but the absence of confirmed bankability and limited independent field data are meaningful risk factors for any long-term investment analysis.
