## Summary

Canadian Solar, founded in 2001 and headquartered in Canada, is one of the world's largest vertically integrated solar manufacturers. Listed on NASDAQ and employing over 17,000 people, the company operates with a production capacity of 51 GW, placing it firmly among the global top-tier players. DAH Solar, by contrast, is a younger Chinese manufacturer established in 2009, with a workforce of over 2,000 employees and a production capacity of 10 GW. Both companies hold Tier 1 bankable status, reflecting recognized financial stability and product reliability as assessed by independent analysts. Canadian Solar's two-decade track record and stock exchange listing give it a strong advantage in large-scale project financing environments, while DAH Solar has been actively expanding its footprint in European markets, including a showcase appearance at the Solar Energy Expo Poland in January 2025.

On the technology side, TOPCon is the dominant cell technology in both portfolios - accounting for 56.3% of Canadian Solar's lineup and 79.6% of DAH Solar's. Canadian Solar leads on peak power output (730 Wp vs. 725 Wp) and maximum module efficiency (24.4% vs. 23.34%), supported by a recently launched 660 W TOPCon panel rated at 24.4% efficiency. Average portfolio efficiency is nearly identical at 22.13% for Canadian Solar and 22.10% for DAH Solar. DAH Solar distinguishes itself through a notably higher share of bifacial modules - 87.1% of its portfolio versus 60.3% for Canadian Solar - making it a strong candidate for ground-mount utility-scale applications where rear-side irradiance gain is a key yield driver. Temperature coefficients for Pmax are close, at -0.305%/°C for Canadian Solar and -0.299%/°C for DAH Solar, giving DAH Solar a marginal edge in high-temperature climates. Average warranty terms are broadly comparable at approximately 29 years for both manufacturers.

For international buyers choosing between the two, Canadian Solar is the lower-risk, more conservative option for utility-scale and commercial C&I projects where lender bankability, brand recognition, and a long operational history carry significant weight. DAH Solar offers a compelling proposition for ground-mount and bifacial-focused deployments, particularly where a broader bifacial portfolio and competitive pricing relative to performance are the deciding factors. Both are credible Tier 1 suppliers, but Canadian Solar's scale and tenure give it an edge in project finance contexts, while DAH Solar's heavily bifacial TOPCon-oriented mix suits buyers prioritizing yield optimization on open-field installations.
