## Summary

MY Solar is a solar brand present in the Polish and Central European market, offering modules built on n-type TOPCon and shingled cell technologies; publicly available information about its own manufacturing capacity, BloombergNEF Tier 1 bankability standing, or track record in debt-financed projects is very limited. Sunova Solar Technology, founded in 2016 and headquartered in China, operates integrated manufacturing facilities across China and Vietnam, holds confirmed BloombergNEF Tier 1 status as of Q1 2024, and carries a CC+ rating from PV Tech's Module Bankability report. The company had shipped a cumulative 7.1 GW of modules worldwide by the close of 2024, supported by a TOPCon cell facility in Yibin, Sichuan with stated capacity of 9 GW. On institutional footprint and independently verified scale, Sunova holds a considerably stronger position than MY Solar.

MY Solar's documented offering centers on shingled and TOPCon modules reaching up to 670 W, with a claimed bifaciality factor of up to 70% and certifications for salt-mist and ammonia resistance - attributes that make the panels a plausible fit for floating, agrivoltaic, and coastal installations. The 30-year product and power-output warranty on its shingled series is a notable commercial claim for a brand of this size. Sunova structures its portfolio into two clearly named families - Zosma for PERC technology and Tangra for n-type TOPCon - across three module form factors (S, M, and L) that address residential rooftop, commercial and industrial, and utility-scale ground-mount applications respectively, with both monofacial and bifacial variants available in each tier.

For buyers whose projects require bankable references, lender acceptance, or independent third-party validation, Sunova is the lower-risk default: its Tier 1 certification and transparent production history reduce financing friction. MY Solar may suit buyers targeting niche technical applications such as floating or agrivoltaic systems, provided the claimed specifications are independently confirmed. The two brands are not interchangeable in terms of institutional recognition, and that gap matters most in large or financed deployments.
