Jinko Solar vs Ulica Solar - solar panel manufacturer comparison

Jinko Solar and Ulica Solar are both Chinese photovoltaic module manufacturers, but they occupy fundamentally different tiers of the global market. Jinko Solar, founded in 2006 and listed on the NYSE, is the world's largest solar panel manufacturer, with a declared production capacity of 130 GW and a workforce of over 33,800 employees. It holds Tier 1 bankable status, making it an accepted supplier for bank-financed and EPC-contracted projects worldwide - a position reinforced by over 300 GW of cumulative module shipments and a record 41 GW delivered in the first half of 2025 alone. Its catalog covers 545 models, with a maximum power output of 735 Wp, average module efficiency of 22.0%, and a peak efficiency of 24.8%, with TOPCon technology representing 39.4% of its lineup. Ulica Solar, founded in 2014, operates at a significantly smaller scale and does not carry Tier 1 bankable status. Its 76-model catalog is heavily concentrated in TOPCon technology at 94.7%, and its average module power of 563.6 Wp exceeds Jinko's 511.1 Wp average, reflecting a portfolio tilted toward high-wattage configurations.

On technical performance, both manufacturers are closely matched in average module efficiency - Jinko at 22.0% and Ulica at 22.3%. Ulica's temperature coefficient of Pmax at -0.303%/°C edges out Jinko's -0.308%/°C, offering a marginal real-world advantage during peak summer conditions - a consideration for residential rooftop installs in warmer climates. Ulica's bifacial panel share of 57.9% is nearly double Jinko's 31.9%, making it a natural fit for ground-mount and agrivoltaic projects that can leverage albedo gain. Ulica also provides a slightly longer average warranty at 29.3 years versus 28.5 years for Jinko. Jinko, backed by 11 consecutive PVEL Top Performer titles, a globally established distribution and service network, and proven track record across utility-scale and commercial C&I deployments, remains the lower-risk benchmark for large projects where supply chain continuity and bankability are non-negotiable.

For international buyers choosing between the two, Jinko Solar is the clear default for utility-scale, bank-financed, or EPC-contracted projects where Tier 1 status is a prerequisite. Ulica Solar may appeal to developers and installers who prioritize a high-density, TOPCon-heavy, bifacial-rich catalog at a competitive price point - particularly for commercial rooftop or open-field ground-mount projects where bankability is not a binding constraint and yield-per-watt drives procurement decisions.
