## Summary

JS Solar is a Chinese photovoltaic manufacturer established in 2007 and headquartered in Wuxi City, Jiangsu Province. The company produces solar cells, modules, inverters, and mounting systems, with a catalog spanning residential and commercial wattage classes. Search results did not surface JS Solar on any BloombergNEF Tier 1 list, suggesting it operates as a smaller-scale supplier rather than a top-tier bankable manufacturer. MY Solar - appearing under the brand identity MY Solar Technology and related to the mypvtech.com domain - is also based in Wuxi and was founded around 2010, with roughly 80 percent of its output reportedly exported globally. Neither brand carries the institutional footprint of the dominant Chinese players such as Jinko, Trina, or JA Solar, making them broadly comparable in market standing.

JS Solar's confirmed product lines include PERC and TOPCon modules covering a wide power range from roughly 360 W to 580 W, suited to residential rooftops, small commercial installations, and mid-scale ground mounts. Efficiency across its catalog averages around 20 percent, with higher-end TOPCon models pushing toward the low-to-mid 22 percent range. MY Solar Technology has positioned its brand around HJT and shingled cell technologies, with HJT modules reaching outputs up to 720 W and claimed efficiencies of approximately 23.8 percent - numbers that, if independently verified, would place it in the premium efficiency tier. Shingled double-glass bifacial panels round out the MY Solar portfolio, targeting applications where rear-side gain and low degradation rates matter.

For a typical buyer in 2025, MY Solar's focus on HJT and shingled technology is technically differentiated, but limited third-party review coverage and the absence of confirmed Tier 1 bankability make project financing harder to secure. JS Solar's broader PERC and TOPCon catalog is more mainstream but similarly lacks bankability credentials. Buyers needing financed utility-scale projects should look to confirmed Tier 1 brands; for smaller self-funded or commercial installations where price and availability dominate, the two brands are broadly interchangeable.
