## Summary

Canadian Solar was founded in 2001 in Guelph, Ontario, Canada by Dr. Shawn Qu and has been publicly listed on the Nasdaq since 2006. The company holds Tier 1 status with BloombergNEF and was named to the S&P Global Commodity Insights Premier List of Tier 1 Cleantech Companies for both 2025 and 2026. With a stated production capacity of approximately 61 GW and cumulative module deliveries of nearly 170 GW across more than 20 countries, it ranks among the top global solar manufacturers by scale. Seraphim was established in 2011 in Changzhou, China, with a reported production capacity of around 13 GW. It has maintained BNEF Tier 1 status for 11 consecutive years and earned PVEL Top Performer recognition six times, with manufacturing operations in both China and the United States and offices in Germany, Japan, Australia, and other key markets. On institutional footprint and global reach, Canadian Solar holds a clear and substantial advantage.

Canadian Solar's portfolio spans the full deployment spectrum. The residential HiKu6 line and its N-type TOPCon variant, the TOPHiKu6 - with efficiencies confirmed by independent reviewers at up to around 22.5% - serve rooftop installations, while the utility-focused HiKu7 series and bifacial BiHiKu modules address large ground-mount and commercial C&I projects. Seraphim's current lineup centers on the TOPCon Nebula series, also built on N-type cells with comparable peak efficiency figures, supplemented by a PERC-based range that competes on price. Reviewers consistently note that Seraphim modules are priced roughly 15-20% below premium-tier brands while retaining Tier 1 bankability, positioning the brand as a strong value choice for residential rooftops and small-to-medium commercial systems where upfront module cost is the primary decision factor.

For buyers financing utility-scale or larger commercial projects where lender and insurer approval is a requirement, Canadian Solar is the safer default, backed by its Nasdaq listing, output scale, and two-decade track record in project development. For residential or small C&I buyers prioritising cost efficiency, Seraphim is a fully bankable and technically competitive alternative. On a standard rooftop installation the two brands are broadly interchangeable; the decision tips firmly toward Canadian Solar only when institutional project bankability is explicitly on the table.
