## Summary

Canadian Solar was founded in 2001 by Dr. Shawn Qu in Ontario, Canada, and is publicly listed on NASDAQ under the ticker CSIQ, with primary manufacturing operations based in China. The company holds confirmed BloombergNEF Tier 1 bankability status and reported annual module production capacity of approximately 61 GW as of 2025, placing it firmly among the top five module manufacturers worldwide. With roughly 20,000 employees and commercial operations spanning more than 20 countries, Canadian Solar carries an institutional footprint that mid-tier competitors cannot match.

Its current product lineup is built around N-type TOPCon technology under the HiKu brand family. The monofacial TOPHiKu6 series addresses residential rooftop and small commercial installations, while the bifacial TOPBiHiKu6 and the high-power TOPBiHiKu7 - topping out at 715 W - are engineered for utility-scale ground-mount and large C&I projects. The TOPCon 2.0 generation announced in 2025 achieves module efficiencies up to 24.4% and a temperature coefficient of -0.28%/°C, benefiting installations in warm climates. All series carry a 30-year performance warranty, which is increasingly a baseline expectation for institutional buyers.

Gamko New Energy, headquartered in Nantong, Jiangsu, China, is a substantially smaller manufacturer with annual production capacity of approximately 1.2 GW as reported in 2023. The company covers a wide power range from a few watts up to 800 W, offering rigid crystalline modules in both PERC and TOPCon variants alongside flexible and bifacial options. It holds standard industry certifications including IEC 61215, IEC 61730, ISO 9001, and CE. However, Gamko does not appear on the BloombergNEF Tier 1 list, which limits its suitability for projects requiring non-recourse financing or EPC-mandated bankability. For most international buyers - particularly those working on grid-tied commercial or utility projects - Canadian Solar is the more defensible default, given its verified bankability, mature TOPCon portfolio, and established global distribution. Gamko may serve cost-sensitive small-scale or off-grid applications where Tier 1 status is not a contractual requirement, but the two brands are not interchangeable for projects where lender approval matters.
