Jinko Solar vs TCL Zhonghuan - solar panel manufacturer comparison

Jinko Solar and TCL Zhonghuan are both China-headquartered, Tier 1 bankable solar module manufacturers, but they differ substantially in scale, market footprint, and strategic focus. Jinko Solar was founded in 2006 and is listed on the NYSE, making it one of the few Chinese solar companies with a primary listing on a major Western exchange. It is the undisputed global shipment leader, having delivered approximately 93 GW in 2024 alone and accumulating close to 370 GW in cumulative shipments. Its annual module production capacity stands at 130 GW, supported by a workforce of over 33,800 employees. TCL Zhonghuan traces its origins to 1981 and is listed on the Shenzhen Stock Exchange. Its core business has traditionally been silicon wafers - it is one of the world's largest wafer suppliers - and its module segment, branded as TCL Solar, is a more recent and still-growing operation that shipped approximately 15 GW in 2025, up more than 80% year-on-year. The company reported a significant financial loss in 2025 and underwent an executive reshuffle, signaling that its module scaling ambitions are still being stress-tested.

On the technology side, Jinko Solar's portfolio of 545 modules is anchored by TOPCon N-type cells, which represent the leading technology category at 39.4% of its lineup. Its maximum module efficiency reaches 24.8%, average efficiency sits at 22.0%, and the company holds a verified world record for a TOPCon cell at 27.79%. With 11 consecutive PVEL Top Performer certifications, Jinko's manufacturing consistency is well-documented. Its broad power range makes it suitable for residential rooftop installs, commercial C&I projects, and large-scale utility ground-mount arrays alike. TCL Zhonghuan's narrower catalog of 65 modules leans heavily on Back Contact (BC) technology, which eliminates front-side electrode grids, improving aesthetics and increasing active cell area. The results are visible in the numbers: TCL Zhonghuan's average module efficiency is 23.1% versus Jinko's 22.0%, average output is 584 Wp versus 511 Wp, bifaciality penetration is 64.6% versus 31.9%, and the temperature coefficient for Pmax is a notably lower -0.272%/°C versus -0.308%/°C, meaning smaller power losses on hot summer days. Its average warranty term of 30 years also edges out Jinko's 28.5 years. TCL Zhonghuan's BC modules are best suited to space-constrained commercial rooftops and premium residential installations where per-square-meter yield matters most.

For international buyers and project developers choosing between the two, Jinko Solar is the lower-risk procurement choice: unmatched supply chain depth, global bankability, and a track record across every project segment. TCL Zhonghuan represents a higher-performance, higher-differentiation option for buyers willing to accept a smaller supplier with a still-maturing module business in exchange for superior efficiency metrics, better bifaciality, and a lower temperature coefficient - attributes that translate directly into higher energy yield in warm climates or high-irradiance locations.
