Solid all-round for its segment
The Jinko Solar JS210MC120 series is designed to maximize energy yield from the same roof or ground-mounted structure. The use of a larger wafer-based architecture and the arrangement of multiple cut cells allows for efficient operation even when the installation is partially shaded, and losses in the string are minimized. In practice, this means more stable production throughout the day and better utilization of morning and afternoon sunlight.
Compared to the competition, these modules stand out due to their high conversion efficiency in a format compatible with standard mounting structures and favorable performance at elevated temperatures, which is important for roofs with limited ventilation. An additional advantage is resistance to environmental conditions and a high level of workmanship, which facilitates long-term operation.
This solution is ideal for investors who want to build a high-density residential, commercial, or utility-scale solar installation, prioritizing reliable performance and predictable yields over many years.
Ranking
Signals from the data
Residential, commercial and shaded-installations.
The top-bin JS210MC120-405 variant reaches 21.1% module efficiency, outperforming all peer comparables: EGing PV STAR Series (20.74%), VSUN405-108BMH-DG (20.74%), and Goldi Solar GS10-M108-BF (20.66%). The ~0.36 pp gap over the nearest competitor translates into measurably higher energy yield per unit of roof or ground area.
JinkoSolar is the only module manufacturer rated 100% bankable in the Bloomberg BNEF 2025 Bankability Report, holding the #1 position for 10 consecutive years. For investors and project lenders, this translates to the lowest counterparty risk and the strongest assurance that a 25-year power warranty will be honored.
Splitting cells in half reduces operating current by 50%, lowering resistive (I²R) losses in strings and limiting the impact of partial shading: when the upper half of the module is shaded, the lower half continues to operate unimpaired. The 210 mm wafer format delivers 405 Wp within a module footprint compatible with standard racking systems.
Jinko Solar guarantees a linear degradation profile over 25 years with a minimum retained output of ~80.7% of nameplate power (standard for their PERC lineup), providing predictable LCOE modeling and long-term bankable performance documentation.
P-type PERC cells exhibit light-induced degradation (LID) of approximately 2% in the first year of operation, compared to <0.5% for N-type TOPCon, which had become the market mainstream by 2026. After 25 years, PERC modules retain roughly 83% of nameplate power vs. ~86% for TOPCon. The JS210MC120 series was released in 2021 and its cell technology trails Jinko's own current Tiger Neo N-type lineup.
The module is monofacial, whereas peer comparable Goldi Solar GS10-M108-BF offers a bifacial variant at the same 405 Wp nameplate power. In ground-mount or white-membrane rooftop installations, bifacial gain can add 5-15% to annual energy yield from rear-side irradiance - an advantage the JS210MC120 series cannot capture.
- At 20.8% efficiency, this panel is on par with typical PERC 400-450W modules
- Power density of 208.1 W/m² matches the PERC 400-450W median
- Temperature coefficient of -0.35%/°C matches the PERC 400-450W median
- Weight of 21.0 kg is typical for PERC 400-450W panels
- #10533 for efficiency, #10489 for temperature performance out of 14129 panels
