## Summary

Canadian Solar is a Canada-headquartered module manufacturer listed on NASDAQ since 2006, with manufacturing spread across Asia and a global commercial footprint. It has been named to S&P Global Commodity Insights' Tier 1 Cleantech Companies list and reports module production capacity around 61 GW annually, placing it among the largest suppliers worldwide. VSUN, owned by Japan's Abalance Group through Fuji Solar, was founded in 2015 with its main factory based in Vietnam; it is a smaller but independently confirmed Tier 1 manufacturer per BloombergNEF's 2025 rankings. In terms of institutional depth and scale, Canadian Solar clearly has the stronger footprint, backed by two decades of public listing history and a much larger production base.

Both brands center their current lineups on N-type TOPCon cell technology. Canadian Solar also fields an HJT line, and its TOPCon and HJT HP modules have earned FM 4478/4480 hail-resistance approvals, while its newest TOPCon 3.0 series pushes output to 670 W at 24.8% efficiency, targeted mainly at utility-scale and C&I projects. VSUN's catalog runs from 390 W to 715 W, with bifacial TOPCon dual-glass modules aimed at ground-mount and commercial installations alongside a more compact 380-460 W range for residential rooftops, backed by a 30-year performance warranty. For buyers, this suggests Canadian Solar is the safer default for large utility-scale portfolios needing top-tier bankability, while VSUN can be a competitive option for residential and mid-scale commercial jobs.

In practical terms the technological gap between the two is narrow - both hold Tier 1 status and rely on similar N-type architectures. The decision often comes down to local distributor support, warranty terms, and pricing rather than any fundamental advantage of one brand over the other.
