## Summary

I have enough distinct information on both brands to write a hedged, qualitative comparison.

MY Solar, operating as MY Solar Technology Co., Ltd (MYPVTECH), is a China-based manufacturer founded in 2010 and headquartered in Guangzhou. It is primarily known as a supplier of portable solar panels, off-grid inverters, and smaller solar power system components rather than as a large-scale rooftop or utility module producer, and it does not appear on major Tier 1 or BloombergNEF bankability lists. Mysolar USA, marketed under the iMysolar brand, is a sub-brand of Mamibot, a manufacturer positioning itself in the HJT and TOPCon module segment for residential, commercial rooftop, and utility-scale projects; the company states an ambition to reach Tier 1 status and reports early production milestones, including over 200 MW delivered globally by the end of 2023, though independent confirmation of current Tier 1 or BloombergNEF listing was not found. Between the two, Mysolar USA shows the stronger institutional footprint, with a clearer manufacturing roadmap, named factory operations, and a documented push toward bankable-tier status, while MY Solar's public presence centers more on trade-fair participation and smaller-format products.

Product-wise, MY Solar's catalog leans toward portable and off-grid solutions, such as foldable or compact panels, small inverters, and energy storage batteries suited to camping, RVs, and off-grid power rather than grid-tied rooftop installations. Mysolar USA, by contrast, offers full-size high-efficiency modules, including HJT half-cell and bifacial panels with reported outputs in the 410W to 740W range, aimed at premium residential rooftops, commercial rooftops, and utility-scale ground-mount deployments, with manufacturer claims of salt-mist and ammonia resistance for harsh climates. This makes the two brands largely non-overlapping in typical use case despite the similar naming.

For a typical homeowner or installer evaluating grid-tied rooftop or utility-scale solar in 2025, Mysolar USA is the more relevant and better-documented option, given its named HJT and TOPCon product lines and stated Tier 1 ambitions, though buyers should independently verify current bankability status before large installations. MY Solar is better suited to buyers seeking portable or off-grid power equipment rather than a primary rooftop solar supplier, so the two are not truly interchangeable and the choice should be driven by application rather than brand similarity.
