## Summary

Canadian Solar is a Canadian manufacturer headquartered in Guelph, Ontario, founded in 2001 and NASDAQ-listed since 2006. It consistently appears on Tier 1 bankability lists (including S&P Global Commodity Insights) and operates at very large scale, with module capacity around 50 GW per year and nearly 170 GW of modules shipped cumulatively worldwide. Solaria, by contrast, is a name that has undergone significant restructuring in recent years: the US-based Solaria (Fremont, California), known for its shingled-cell PowerXT panels, merged with Complete Solar in 2022, sold its shingled-cell patents to Maxeon in 2023, and in April 2025 the combined entity, Complete Solaria, rebranded entirely as SunPower. A separate, unrelated company, Solaria Energia y Medio Ambiente of Madrid, closed its own module production lines years ago and now focuses on developing and operating utility-scale solar plants rather than manufacturing panels. As a result, Canadian Solar today holds a far stronger and clearer institutional footprint as an active module producer.

Canadian Solar's product range spans TOPCon modules (the TopHiKu6 series, reaching roughly 22.5 percent efficiency) as its high-volume offering for residential and commercial rooftops, alongside the HiHero HJT line positioned as a premium, high-bifaciality option (up to around 95 percent) for projects prioritizing maximum yield. The company serves both rooftop and utility-scale ground-mount segments, and it also supplies battery storage through its e-STORAGE division. Solaria's PowerXT panels, built on shingled-cell technology, were once well regarded for high power density in compact roof spaces, but that brand no longer exists as an independent panel manufacturer.

For a typical buyer today, Canadian Solar is clearly the safer default given its active production, Tier 1 status, and established distribution network. Solaria is no longer a functioning standalone solar panel brand, so this comparison is largely historical rather than a reflection of current market competition - buyers previously considering Solaria panels should look at SunPower's current lineup instead.
