## Summary

Mysolar USA is a brand under Mamibot, positioned as an emerging US-based panel manufacturer that is actively working toward Tier 1 classification rather than having secured it yet. The company promotes state-of-the-art HJT and shingled cell technology, including bifacial N-type HJT modules, but it lacks the long operating history and BloombergNEF bankability record that established players have. Silfab Solar, by contrast, is a well-established North American manufacturer headquartered in Ontario, Canada, with additional production in Washington State and a newer fully integrated cell-and-panel facility in Fort Mill, South Carolina. Silfab is recognized as a Tier 1 bankable manufacturer and has secured significant capital, including 100 million dollars in financing in late 2024 and 110 million dollars in 45X Advanced Manufacturing Tax Credits in 2025, reflecting a much stronger institutional footprint and financial backing than Mysolar USA currently has.

Mysolar USA's catalog spans poly, mono, bifacial and shingled panels using full-cell and half-cut architectures, with power ratings reported from roughly 340W up to 720W on premium HJT models, suggesting an emphasis on high-wattage bifacial products for a mix of residential and commercial installs, though independent field data is limited. Silfab's lineup is more thoroughly documented by third-party reviewers, with around a dozen models averaging about 22.6 percent efficiency and top modules reaching into the high 20s in efficiency claims; the company is frequently ranked among the top solar brands sold in the US and Canada, and its panels are commonly specified for premium residential rooftops as well as commercial projects, supported by domestic manufacturing that appeals to buyers seeking US or North American content.

For a typical 2025 buyer prioritizing bankability, warranty support, and a proven installation track record, Silfab is the more conservative and better-documented choice, given its Tier 1 status, larger manufacturing footprint, and consistent presence in independent buyer's guides. Mysolar USA may appeal to buyers interested in cutting-edge HJT technology or high-wattage bifacial modules, but its shorter track record and pending Tier 1 status mean it currently carries more due-diligence risk and less third-party verification than Silfab.
