The ~0.36 pp gap over the nearest competitor translates into measurably higher energy yield per unit of roof or ground area. - **Bloomberg BNEF bankability leader** - 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. - **120 half-cut cell architecture on 210 mm wafers** - 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. - **25-year linear power warranty** - 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. ## Cons - **PERC technology - higher LID and lower long-term retention** - 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. - **Monofacial design** - 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. ## About this series 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. ## Notable figures - 20.5% module efficiency - 1.1pp better than the \*\*PERC 0-400W\*\* median of 19.4% - Power density of 205.5 W/m² packs 11.3 W/m² more into the same footprint vs \*\*PERC 0-400W\*\* median (194.2 W/m²) - At -0.35%/°C, hot weather performance is typical for \*\*PERC 0-400W\*\* panels - #11389 for efficiency, #10489 for temperature performance out of 14129 panels ## Questions ### What is the maximum power output of the Jinko Solar JS210MC120 series and how many cells does the module contain? The JS210MC120 series reaches a peak output of up to 405 Wp. The MC120 designation refers to 120 mono-crystalline half-cut cells, meaning each full cell is split in two compared to a standard layout. This reduces internal current levels, lowers resistive losses, and improves real-world conversion efficiency under typical installation conditions. ### Is the Jinko Solar JS210MC120 with PERC technology a good choice for a residential rooftop installation? The PERC cell technology in the JS210MC120 series uses a rear-surface passivation layer to reflect unabsorbed photons back through the cell, increasing energy yield. For residential use this means better output under diffuse irradiance, which is common in Central European climates. As a Tier 1 manufacturer, Jinko Solar has the financial stability to honor its warranties throughout the full service life of the modules. ### How does the JS210MC120 series handle partial shading from a chimney or dormer window? The half-cut cell layout splits the module into two electrically independent halves. When shading falls on one section, only that half reduces output while the rest of the module continues operating at full power. Combined with the larger 210 mm wafer format, this significantly limits string power losses on rooftops where shading occurs seasonally or during morning and afternoon hours. ### What warranty comes with the Jinko Solar JS210MC120 panels and what does it cover? Jinko Solar provides a 25-year linear power output warranty for the JS210MC120 series, guaranteeing the modules retain at least 80-83% of their rated output after 25 years of operation. This is supplemented by a standard product warranty covering material defects and workmanship. As a Tier 1 manufacturer, Jinko Solar has the financial backing to make warranty claims a realistic option for the full warranty period. ### Do the JS210MC120 panels perform well in summer when the roof surface gets very hot? The JS210MC120 series features a favorable temperature coefficient of power, meaning it loses proportionally less output at elevated temperatures compared to older cell types. On a south-facing roof with limited rear ventilation, this translates into more stable production during hot summer months and a better annual energy yield compared to modules with a higher temperature sensitivity. ### Are the Jinko Solar JS210MC120 modules weather-resistant and suitable for a pitched roof installation? Yes, the JS210MC120 series is engineered for long-term outdoor service including snow load and wind pressure typical of Central European winters. The module frame dimensions and standard mounting slot spacing are compatible with widely used rail-based racking systems for pitched roofs covered with ceramic tile, metal tile, or standing-seam sheet metal, simplifying hardware selection and installation planning. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/JS210MC120-405W-12971c45aa59.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Luxor Solar LX-440M/182-108+GG](https://comparepv.com/panel/luxor-solar-lx-440m-182-108-gg) | 440 W | Cooler, +2.6 pp, +5 yr warranty | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | Lighter, +2.5 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | Lighter, +2.5 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/2\*4\*20)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-2-4-20) | 400 W | Lighter, +2.5 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/4\*4\*40)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-4-4-40) | 400 W | Lighter, +2.5 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/2\*4\*19)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-2-4-19) | 380 W | Lighter, +2.5 pp, +5 yr warranty | | [Jetion JT440SYK(B)](https://comparepv.com/panel/jetion-jt440syk-b) | 440 W | Cooler, +2.4 pp, +5 yr warranty | | [Luxor Solar LX-440M/182-108+](https://comparepv.com/panel/luxor-solar-lx-440m-182-108) | 440 W | +45 W, cooler, +2.4 pp | | [Jinko Solar JS210MC120-390](https://comparepv.com/panel/jinko-solar-js210mc120-390) | 390 W | Very close match | | [Jinko Solar JS210MC120-400](https://comparepv.com/panel/jinko-solar-js210mc120-400) | 400 W | +0.3 pp | | [Jinko Solar JS210MC120-405](https://comparepv.com/panel/jinko-solar-js210mc120-405) | 405 W | +10 W, +0.6 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +115 W, cooler, +4.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +100 W, cooler, +4.3 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +110 W, cooler, +4.2 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +110 W, cooler, +4.2 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +95 W, cooler, +4.0 pp | --- Source: https://comparepv.com/panel/jinko-solar-js210mc120-395 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
