## Summary

Canadian Solar is a Canadian manufacturer headquartered in Guelph, Ontario, publicly listed on NASDAQ since 2006, with manufacturing concentrated in China and Southeast Asia. It appears on S&P Global's Premier List of Tier 1 Cleantech Companies and operates at massive scale, with module capacity exceeding 50 GW per year as of its 2025 plans, placing it among the largest module makers globally. Solitek, by contrast, is a Lithuanian manufacturer founded in 2009 (as Baltic Solar Solutions, rebranded Solitek in 2014), producing out of a Vilnius facility with annual capacity around 250 MW - roughly two orders of magnitude smaller than Canadian Solar. In terms of institutional footprint and financial bankability, Canadian Solar has the clear edge.

Canadian Solar's catalog spans residential rooftop modules through utility-scale ground-mount products, built on a technology mix still led by PERC alongside a growing share of N-type TOPCon (its TOPHiKu7 and TOPBiHiKu6 lines) and a small HJT allocation, with average module efficiency around 20-21%. Solitek instead positions itself in a premium, specialized niche: glass-glass and bifacial modules plus Full Black aesthetic panels, aimed largely at residential prosumer and commercial and industrial (C&I) installations across Northern Europe, backed by Cradle to Cradle Gold certification and a manufacturing process it markets as net-zero. Solitek has also expanded into Lithuanian-made battery energy storage systems for the C&I segment.

For a buyer prioritizing scale, bankability, and price competitiveness on utility or large commercial projects, Canadian Solar remains the safer default choice. Solitek suits buyers who specifically value a European supply chain, shorter logistics, a long 30-year warranty, and a sustainability-focused manufacturing story, accepting a much smaller production footprint and lower international brand recognition in exchange. The two brands are not interchangeable: the right pick depends on whether scale and cost or European origin and sustainability credentials matter more to the project.
