At a module temperature of 65°C (typical Polish summer), this translates to approximately 2.1% higher energy yield compared to a same-rated PERC panel. - **30-year linear power warranty** - Jinko guarantees linear degradation of ≤0.4%/year, ≥87.4% of rated power after 30 years, and first-year LID degradation ≤1%. Direct peer comparables (GCL M10/54H, Phono Solar TwinPlus) and the majority of the market offer a standard 25-year power warranty, making this series more favorable in long-horizon LCOE calculations. - **Peak efficiency 21.51% – top of all-black segment** - The 420 Wp variant reaches 21.51% STC efficiency, matching the Solarspace SS8-54HSB (21.51%) and outperforming the Phono Solar TwinPlus (20.98%). For constrained roof areas, this enables higher system capacity on the same surface versus mid-range products. - **Reinforced frame: 5,400 Pa snow, 2,400 Pa wind** - Certified mechanical load ratings of 5,400 Pa (snow) and 2,400 Pa (wind) per IEC 61215 meet or exceed market standards and are sufficient for snow load zone III per PN-EN 1991-1-3, covering most of Poland, without requiring additional protective rails. - **BNEF Tier-1 manufacturer – global market leader** - Jinko Solar holds the #1 position on the BNEF Tier-1 Q2 2026 list with 120 GW/year of production capacity, ensuring bankability for project financing and minimizing manufacturer insolvency risk across the 30-year warranty horizon. ## Cons - **Series discontinued (2023)** - The 54HL4-B series ended production in 2023 and was superseded by the 54HL4R-B (425–445 Wp). New module availability is limited to distributor stock, complicating future system expansions with identical panels and potentially extending warranty claim processing times. - **Entry-variant efficiency below peer comparables** - The lowest variant in the series (400 Wp) achieves only 20.48% efficiency, while peer comparables (GCL-M10/54H, Solarspace SS8-54HSB) report maximums of 21.5% without disclosing lower bounds — the 1.03 pp efficiency spread within the series indicates that lower-wattage variants lose their N-type technological edge over modern premium PERC cells. ## About this series The Jinko Solar Tiger Neo N-type 54HL4-B series represents a breakthrough in prosumer installation design, combining advanced technology with elegant design. At the heart of these modules is **innovative N-type TOPCon technology**, which drastically minimizes light-induced degradation, providing users with significantly higher yields over the long term. This solves the problem of efficiency loss in older cell types, offering energy stability for over 30 years. Thanks to the **full All-black aesthetics**, these panels are an ideal solution for demanding investors who value the appearance of the rooftop installation as much as its parameters. The 54HL4-B series stands out from the competition with its excellent performance in diffuse light conditions, which is crucial for the Polish climate zone. Another advantage is the **exceptionally low temperature coefficient**, which ensures the modules maintain high efficiency even during summer heatwaves. This product is primarily dedicated to modern residential construction, where limited roof space requires the installation of components with the highest power density. **Reinforced frame construction** guarantees resistance to high snow and wind loads, making these panels a reliable component of a home renewable energy system. It is an excellent choice for those seeking a technological advantage and uncompromising build quality. ## Notable figures - Efficiency of 21.5% matches the \*\*N-type 400-450W\*\* median - At 215.1 W/m², this panel generates 3.2 W/m² less per unit area than \*\*N-type 400-450W\*\* median (218.3 W/m²) - At -0.29%/°C, hot weather performance is typical for \*\*N-type 400-450W\*\* panels - Ranked #7894 out of 14005 panels for efficiency in the database ## Questions ### How does the N-type TOPCon technology in the Jinko Solar Tiger Neo 54HL4-B series differ from older PERC cells? The N-type TOPCon cells used in the 54HL4-B series exhibit significantly lower light-induced degradation (LID) compared to standard PERC modules. In practical terms, the module loses minimal efficiency in year one, and Jinko Solar guarantees at least 87.4% of nominal power output after 30 years. Older P-type PERC cells can lose up to 2–3% of rated power in the first year of operation alone. ### Are the Jinko Solar Tiger Neo 54HL4-B panels suitable for installation on a small pitched roof? Yes. The 54HL4-B All-black module rated at 420 Wp uses a 54-cell layout measuring 1722×1134×30 mm and weighing 22 kg, making it one of the more compact and lightweight high-power formats available. The high power density lets you generate more kilowatts from limited roof space — a key advantage on smaller residential rooftops. The reinforced frame handles snow loads up to 5,400 Pa. ### What warranty does Jinko Solar offer on the Tiger Neo 54HL4-B series? Jinko Solar provides a 25-year product warranty covering defects in materials and workmanship, along with a 30-year linear power warranty. Modules retain at least 91.6% of nominal power after 10 years and at least 87.4% after 30 years. As a Bloomberg NEF Tier 1 manufacturer, Jinko Solar offers strong assurance that warranty claims will actually be honored over the module's lifetime. ### How does the 54HL4-B series perform on overcast days typical of the Polish climate? The Tiger Neo 54HL4-B is engineered for low-light and diffuse irradiance conditions, which is critical in Poland where cloudy days number 160–180 per year. N-type TOPCon technology harvests photons more efficiently under weak irradiance than PERC cells do. The low temperature coefficient of approximately -0.30%/°C also means the module performs well in both winter cold and summer heat waves. ### How does the All-black Jinko Solar Tiger Neo 54HL4-B visually differ from standard solar modules? The 54HL4-B is available exclusively in a full All-black aesthetic — black cells, black anodized frame, and black backsheet create a uniform, premium appearance on the roof. This design is aimed at homeowners for whom building aesthetics are a priority. Unlike standard modules with white backsheets and silver frames, this series blends seamlessly into dark roof tiles or membranes. ### Is the Jinko Solar Tiger Neo N-type 54HL4-B series still available for purchase? The 54HL4-B series has been discontinued by Jinko Solar. Limited stock may still exist with some distributors, but it is no longer in regular production or supply. The successor product is the Tiger Neo 54HL4R-B (Hot 2.0), offering higher power outputs up to 445 W while retaining the All-black design and TOPCon technology. For new installations, we recommend choosing an actively manufactured model to ensure supply continuity and warranty support. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/JKM400-420N-54HL4-B-F3-EN-05bd87bb1cb9.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Just Solar JST-EDMH-(445-465)W-TD (465W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-465w-class) | 465 W | +45 W, lighter, +2.3 pp | | [Luxor Solar LX-465M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-465m-182r-96-gg) | 465 W | +45 W, cooler, +2.3 pp | | [Maxeon SPR-MAX7-470](https://comparepv.com/panel/maxeon-spr-max7-470) | 470 W | +50 W, +2.2 pp, +10 yr warranty | | [AIKO AIKO-A470-MAH54Mb](https://comparepv.com/panel/aiko-aiko-a470-mah54mb) | 470 W | +50 W, cooler, +2.1 pp | | [AIKO AIKO-A460-MAH54Mb](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a460-mah54mb-1) | 460 W | +40 W, lighter, +2.1 pp | | [TCL Zhonghuan HSM-BD54-LA470](https://comparepv.com/panel/tcl-zhonghuan-hsm-bd54-la470) | 470 W | +50 W, cooler, +2.1 pp | | [Jinko Solar JS182MHC108-390](https://comparepv.com/panel/jinko-solar-js182mhc108-390) | 390 W | Hotter, -1.5 pp, -5 yr warranty | | [Jinko Solar JKM395M-54HL4-V](https://comparepv.com/panel/jinko-solar-jkm395m-54hl4-v) | 395 W | Hotter, -1.3 pp, -5 yr warranty | | [Jinko Solar JS182MHC108-395](https://comparepv.com/panel/jinko-solar-js182mhc108-395) | 395 W | Hotter, -1.3 pp, -5 yr warranty | | [Jinko Solar JKM400M-54HL4-V](https://comparepv.com/panel/jinko-solar-jkm400m-54hl4-v) | 400 W | Hotter, -1.0 pp, -5 yr warranty | | [Jinko Solar JS182MHC108-400](https://comparepv.com/panel/jinko-solar-js182mhc108-400) | 400 W | Hotter, -1.0 pp, -5 yr warranty | | [Jinko Solar JKM405M-54HL4-V](https://comparepv.com/panel/jinko-solar-jkm405m-54hl4-v) | 405 W | Hotter, -0.8 pp, -5 yr warranty | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +90 W, cooler, +3.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +75 W, cooler, +3.3 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +85 W, cooler, +3.2 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +70 W, cooler, +3.0 pp | --- Source: https://comparepv.com/panel/jinko-solar-jkm420n-54hl4-b Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
