## Summary

Jinko Solar, founded in 2006 and listed on the NYSE, is the world's leading solar module manufacturer by shipments - having delivered 86.8 GW in 2025, its seventh consecutive year at the top of global rankings. The company employs over 33,800 people and maintains a production capacity of 130 GW across 12 global manufacturing facilities, giving it unmatched scale and supply chain reach. Tongwei, founded in 2013 and listed on the Shanghai Stock Exchange (SSE), is a younger but fast-growing competitor with a more focused portfolio of 122 panel models. Critically, Tongwei is also a major upstream player in the solar value chain, holding significant polysilicon and cell manufacturing capacity - a degree of vertical integration that strengthens its cost position. Both manufacturers hold Tier 1 bankable status, making them eligible for project financing from leading international institutions.

Jinko Solar's broad 545-model portfolio, spanning a maximum output of 735 Wp and an average of 511 Wp, serves the full range of installation types - residential rooftop installs, commercial and industrial (C&I) systems, and large-scale utility-scale ground-mount projects. Its primary cell technology is TOPCon (39.4% of portfolio), with a maximum module efficiency of 24.8% and an average of 22.0%. Tongwei differentiates itself through a strongly bifacial-oriented lineup: 68.9% of its modules are bifacial, compared to just 31.9% for Jinko, making Tongwei particularly compelling for utility-scale ground-mount projects where rear-side irradiance gains can materially improve energy yield. Tongwei also leads on temperature coefficient (-0.284%/°C vs. -0.308%/°C), average module power (584 Wp vs. 511 Wp), average efficiency (22.6% vs. 22.0%), and average warranty length (29.5 years vs. 28.5 years). Its TNC 2.0 series earned PVEL Top Performer recognition in 2025 across all tested reliability categories.

For buyers prioritizing brand recognition, product breadth, and proven global supply chain reliability, Jinko Solar remains the default choice - especially for residential rooftop and C&I projects where a wide model selection and strong bankability matter most. Tongwei is the stronger candidate for utility-scale or ground-mount deployments where bifacial performance, lower temperature losses, and a longer warranty horizon can meaningfully reduce LCOE over a 25-30 year project lifetime. Both are credible, bankable options, but Tongwei's technical metrics position it as optimized for high-performance large-scale projects rather than the full breadth of installation types where Jinko excels.
