## Summary

Silfab is a North American solar panel manufacturer founded in 2010 and headquartered in Mississauga, Ontario, Canada, with production facilities in Washington State and a new module plant under development in South Carolina. As a recognized Tier 1 bankable manufacturer, the company has built its reputation on domestically made, premium-quality modules, earning Top Performer status in the PVEL Industry Scorecard. Its manufacturing footprint is scaling toward approximately 1 GW of cell production and 1.3 GW of module output annually once the South Carolina facility reaches full operation. Trina Solar, by contrast, was founded in 1997 in Changzhou, China, and has grown into one of the world's largest solar manufacturers, with annual production capacity estimated at around 100 GW - placing it consistently among the top four Chinese producers alongside LONGi, JinkoSolar, and JA Solar. Trina Solar has maintained a continuous presence on BloombergNEF's Tier 1 list and is one of the most widely recognized names in institutional project finance globally. On sheer scale and institutional footprint, Trina Solar holds a commanding and largely uncontested advantage.

Silfab's current product portfolio centers on the Prime series, which has transitioned from mono-PERC half-cut cells to N-type TOPCon technology, covering an output range of 370 W to 430 W. The lineup targets residential rooftop and light commercial installations in North America, and the brand's domestic manufacturing credentials make it a compelling choice for U.S. buyers seeking compliance with Buy American Act requirements or domestic content adders under federal clean energy incentive programs. Trina Solar's Vertex product family addresses a much wider spectrum: the Vertex S+ line, built on N-type TOPCon cells, serves both residential and commercial rooftop applications, while the large-format Vertex N series - with module outputs up to 760 W and cell efficiencies confirmed at 24.5% by pv magazine - is engineered for utility-scale ground-mount projects. This product ladder allows Trina Solar to compete coherently across virtually every installation category and geography.

For most international buyers, Trina Solar is the stronger default given its scale, global distribution network, deep installer familiarity, and proven performance across residential, commercial, and utility segments. Silfab is a well-regarded and technically credible alternative, but one whose value proposition is closely tied to the North American market and its domestic content incentive landscape. Buyers outside that context will find Trina Solar far easier to source, finance, and service over a module's 25-plus-year lifespan.
