## Summary

JA Solar is one of the world's largest solar panel manufacturers, founded in 2005 and headquartered in China, with shares listed on the Shenzhen Stock Exchange. With over 37,000 employees and a production capacity exceeding 100 GW annually, the company consistently ranks among the top global module suppliers by shipment volume. JA Solar has held Tier 1 bankable status with BloombergNEF for over a decade, reaffirmed by S&P Global Commodity Insights in 2025, and has been recognized as a PVEL Top Performer for the tenth consecutive time. Mogen Solar, by contrast, is a considerably smaller manufacturer with no Tier 1 bankable designation, a public product portfolio of just 5 modules, and limited publicly available information regarding its founding history, employee headcount, or annual production scale.

JA Solar's broad portfolio of 524 models delivers an average module power of 441.7 Wp, a maximum efficiency of 24.4%, and an average efficiency of 20.87%, with 44.27% of its lineup comprising bifacial panels. Its technology mix is predominantly PERC - representing over 52% of models - alongside a growing TOPCon segment, making it well-suited for residential rooftop installs, commercial and industrial (C&I) projects, and large utility-scale ground-mount farms. Mogen Solar's compact five-model range is built entirely on TOPCon technology with 100% bifacial modules, achieving an average efficiency of 21.52% - slightly above JA Solar's portfolio average - and a marginally better temperature coefficient of -0.3%/°C versus JA Solar's -0.3226%/°C. This focused positioning makes Mogen Solar a candidate for ground-mount or flat-roof applications where rear-side irradiance gain is achievable and buyers specifically require modern N-type bifacial modules.

For most international buyers operating under project finance or EPC contracts with bankability requirements, JA Solar represents the lower-risk choice, backed by its Tier 1 status, global distribution infrastructure, and independently verified reliability credentials. Mogen Solar may appeal to smaller integrators or cost-sensitive buyers who prioritize an all-bifacial TOPCon lineup and face fewer bankability constraints, but the limited public track record and absence of Tier 1 recognition introduce meaningful counterparty and long-term warranty risk for larger or finance-dependent projects.
