## Summary

Phono Solar is a Chinese photovoltaic manufacturer headquartered in Nanjing, established in 2004 as a subsidiary of SUMEC Group Corporation - itself part of SINOMACH, the Chinese state-owned industrial conglomerate ranked 281st on the 2023 Fortune 500. With an annual production capacity of approximately 3 GW and a continuous listing on Bloomberg NEF's Tier 1 bankability roster since 2014, Phono Solar carries one of the strongest institutional endorsements available in the mid-tier module segment. MY Solar is a smaller, technology-focused brand with Chinese manufacturing roots and an active distribution channel serving the Polish market; it publicly targets Tier 1 recognition but does not yet appear on BNEF's published lists, which makes project financing against its modules harder without additional lender due diligence.

Phono Solar's catalog spans residential rooftops, commercial and industrial installations, and utility-scale ground mounts, drawing on a technology mix of PERC, TOPCon, and N-type cells. Its latest Quasar back-contact bifacial module achieves a module efficiency of 23.27%, and the brand earned Top Performer recognition in the Kiwa PVEL 2025 PV Module Reliability Scorecard across multiple test categories. MY Solar differentiates itself with a narrower but technically ambitious lineup: N-type TOPCon bifacial panels up to 580W, shingled modules up to 670W, and HJT GOLD glass-glass panels up to 720W, all backed by 30-year product and performance warranties. Certifications for salt-fog and ammonia resistance make its offering genuinely competitive for floating solar, agrivoltaic projects, and coastal sites where standard modules face accelerated degradation.

For most buyers - particularly those relying on project finance or long-term warranty backstop - Phono Solar is the lower-risk default, supported by more than a decade of bankability data, independent lab validation, and a state-enterprise parent with deep financial reserves. MY Solar is a credible option for installers with specific niche requirements, but limited independent performance history means it warrants closer scrutiny before deployment at scale. The two brands are not interchangeable where bankability matters; in specialized off-grid or floating contexts, MY Solar's technical focus narrows that gap.
