Tier-1 status confirms full bankability — project finance lenders accept these modules without additional credit enhancements, lowering the cost of capital for investors. - **Half-cut 182mm cells – shade tolerance** - The half-cut cell layout halves the operating current, significantly reducing resistive losses (I²R). Under partial shading from chimneys, antennas, or roof ridges, output losses are substantially lower than with full-cell modules. The M10 (182 mm) format strikes an optimal balance between power output and logistics/installation practicality. - **Up to 21.48% efficiency – top of the PERC class** - The peak module efficiency of 21.48% matches the highest result among PERC-class peer comparables (JS Solar JS182MHC120: 21.48%, Vikram Solar SOMERA: 20.91%). The series is fully competitive with direct peers at the same 465 Wp nameplate power. - **Active series – supply continuity assured** - The series remains in active production (released 2021, discontinued: false), ensuring replacement module availability in case of mechanical failure and maintained distributor inventory. This is material when planning service continuity over the 25-year operational horizon. - **25-year linear power warranty** - JinkoSolar provides a 25-year linear power output warranty, confirmed by official warranty documentation (JinkoSolar Limited Warranty REV. EN20240521-LINEAR). The product (workmanship) warranty stands at a typical 12 years — one of the longer coverages in the mainstream PERC module segment. ## Cons - **PERC – previous-generation technology** - Since 2024, TOPCon has surpassed 66% of global production capacity and is becoming the new market standard. Peer comparable Luxor Solar ECO LINE TOPCon achieves 23.6% efficiency vs. this series' maximum of 21.48% — a gap of 2.1 percentage points. TOPCon also features a superior temperature coefficient (-0.29%/°C vs. -0.34%/°C for PERC), translating to approximately 1.5–2.5% higher annual energy yield under real operating conditions. - **Monofacial only – lost bifacial energy potential** - The series is monofacial (is\_bifacial: false), while the direct peer comparable Luxor Solar ECO LINE TOPCon is a bifacial glass-glass module. Ground-mount and light-colored roof installations can capture an additional 5–15% energy from reflected irradiance on the module's rear side — a yield gain unavailable with this series. ## About this series The Jinko Solar JS182MHC120 series is designed to maximize energy yield while maintaining a convenient mounting format - these modules feature **monocrystalline cells** in a **half-cut** configuration, which helps to mitigate the effects of partial shading and reduces losses due to heating. In practice, this translates to more stable operation of the installation in real-roof conditions, where shadows from chimneys, antennas, or roof edges can reduce production. The JS182MHC120 stands out due to its well-engineered design focused on **higher reliability** - a robust frame, anti-reflective glass, and a sealed junction box with a high level of protection are standard features, which make it easy to operate in the Polish climate (wind, snow, humidity). This is a good option for both residential and commercial installations, where **long-term profitability** and predictable production are important, rather than just meeting catalog specifications. Compared to many competing modules in the same class, the JS182MHC120 series places a strong emphasis on practical loss reduction and resistance to typical field-related problems. ## Notable figures - Efficiency of 21.0% matches the \*\*PERC 450-500W\*\* median - Power density of 210.2 W/m² matches the \*\*PERC 450-500W\*\* median - Temperature coefficient of -0.34%/°C matches the \*\*PERC 450-500W\*\* median - 23.0 kg weight - 1.5 kg lighter than \*\*PERC 450-500W\*\* median (24.5 kg), reducing installation effort - #9696 for efficiency, #8778 for temperature performance out of 14005 panels ## Questions ### What is the power warranty on the Jinko Solar JS182MHC120 panels? The JS182MHC120 series comes with a 25-year linear power output warranty — the manufacturer guarantees that over a quarter century the panel will not exceed specified degradation thresholds. As a Tier 1 manufacturer, Jinko Solar also provides a separate product workmanship warranty (typically 10–12 years) covering manufacturing defects. This is one of the longer warranty packages available in this price class. ### Do the half-cut cells in the JS182MHC120 actually reduce shading losses? Yes. In a half-cut cell layout, each cell is split in half, reducing internal resistance and limiting hot-spot formation. When a chimney, antenna, or roof edge shades part of the module, energy losses are noticeably smaller than with conventional full-cell designs. For a typical residential rooftop with various obstructions, this translates to a real gain — estimated at a few percentage points of additional annual energy yield compared to older module architectures. ### Is the JS182MHC120 a monofacial or bifacial module? The JS182MHC120 series is a monofacial module — it captures solar energy from the front side only and does not feature a transparent backsheet. For the vast majority of pitched roof installations this is the optimal choice, as bifacial gain is most significant in ground-mounted systems with highly reflective albedo surfaces where the module's rear side receives meaningful irradiance. ### Are the Jinko Solar JS182MHC120 panels suitable for pitched roof installations in Central European climates? Yes, the JS182MHC120 series is well suited for rooftop installations in Central Europe. Its aluminum frame, anti-reflective coated glass, and a high IP-rated weatherproof junction box handle Polish and Central European conditions reliably — including snow loads, wind, and humidity. The PERC technology combined with the half-cut cell layout ensures stable production even under the variable cloud cover typical of the region. ### What does the 182 designation in JS182MHC120 mean and how does it affect power output? The number 182 refers to the cell size of 182×182 mm (M10 wafer format). Larger cells have a greater active surface area, which directly translates to higher module power output — hence the up to 465 Wp rating of this series. The M10 format is currently one of the dominant industry standards, ensuring broad component availability and full compatibility with standard racking and mounting systems on the market. ### How do the PERC cells in the JS182MHC120 differ from older BSF technology and does it matter in practice? PERC (Passivated Emitter and Rear Cell) cells feature an additional passivation layer on the rear surface that reflects photons back into the active layer instead of losing them as heat. Compared to conventional BSF cells, PERC efficiency is approximately 1–2 percentage points higher. In practice, this means the JS182MHC120 delivers greater power output in the same physical footprint and a better energy yield per square meter of available roof area. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/JS182MHC120-465W-a9e1b038c637.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, +3.8 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +50 W, cooler, +3.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, +3.5 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, +3.5 pp, +5 yr warranty | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | Cooler, +3.5 pp, +5 yr warranty | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | Cooler, +3.5 pp, +5 yr warranty | | [Jinko Solar JKM440M-60HL4](https://comparepv.com/panel/jinko-solar-jkm440m-60hl4) | 440 W | -15 W, heavier, -0.6 pp | | [Jinko Solar JKM445M-60HL4](https://comparepv.com/panel/jinko-solar-jkm445m-60hl4) | 445 W | -10 W, heavier, -0.4 pp | | [Jinko Solar JKM450M-60HL4-V](https://comparepv.com/panel/jinko-solar-jkm450m-60hl4-v) | 450 W | Heavier | | [Jinko Solar JS182MHC120-450](https://comparepv.com/panel/jinko-solar-js182mhc120-450) | 450 W | -0.2 pp | | [Jinko Solar JKM455M-60HL4](https://comparepv.com/panel/jinko-solar-jkm455m-60hl4) | 455 W | Heavier | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +105 W, cooler, +3.8 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +100 W, cooler, +3.6 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +95 W, cooler, +3.4 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +85 W, cooler, +3.4 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +85 W, cooler, +3.4 pp | --- Source: https://comparepv.com/panel/jinko-solar-js182mhc120-455 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
