Jinko Solar vs Longi Solar - solar panel manufacturer comparison

Jinko Solar and LONGi Solar are two of China's largest solar PV manufacturers and perennial rivals for the title of global module shipment leader. Jinko Solar, founded in 2006 and listed on the NYSE, holds a declared production capacity of 130 GW and a portfolio spanning 545 module models - one of the broadest lineups in the industry. The company shipped 86.8 GW of modules in 2025, claiming the global sales leadership for the seventh time. LONGi Solar, founded in 2000 and listed on the Shanghai Stock Exchange, operates at 85-90 GW of production capacity and employs 37,853 people compared to Jinko's 33,830. Both manufacturers hold Tier 1 bankable status, meaning project financiers and lenders recognize them as low-risk counterparties - a critical credential for utility-scale and commercial project financing worldwide.

On the technology side, Jinko Solar has built its reputation on N-type TOPCon cells, which represent 39.4% of its current portfolio and enable a maximum module efficiency of 24.8% and a maximum panel output of 735 Wp. Its broad and competitively priced lineup makes it a natural fit for large utility-scale ground-mount projects where volume and cost per watt are decisive, as well as for residential rooftop installers who need reliable supply at scale. LONGi Solar has differentiated itself through a push into back-contact (BC) and HIBC cell architectures, achieving a portfolio maximum efficiency of 25% and a higher average module efficiency of 22.6% versus Jinko's 22.0%. LONGi's modules also carry a better average temperature coefficient of Pmax (-0.291 versus -0.308), meaning smaller output losses during hot weather, and a higher share of bifacial modules in its lineup (39.6% versus 31.9%) - advantages that are particularly compelling for commercial and industrial (C&I) rooftops and space-constrained ground-mount arrays. Its Hi-MO and HIBC product lines are positioned as premium offerings for buyers prioritizing long-term energy yield over upfront cost.

For international buyers choosing between the two, the decision typically comes down to budget versus performance premium. Jinko Solar delivers strong bankability, the widest product selection, and competitive pricing backed by a proven high-volume supply chain - making it the pragmatic choice for large procurement programs and cost-sensitive residential markets. LONGi Solar commands a price premium but offers measurably superior average efficiency, a better thermal performance profile, and a technology roadmap centered on next-generation back-contact cells - making it the preferred option for high-yield commercial projects, space-constrained installations, or buyers who prioritize long-term performance over initial outlay.
