These are **bifacial dual glass modules**, capable of harnessing not only light falling on the front but also the reflection from the rear substrate - effectively boosting yield without increasing rooftop surface area. At the heart of this series are **N-type TOPCon cells** supported by the manufacturer's proprietary **HOT 3.0** solutions, translating to improved operational stability, reduced degradation-related losses, and higher efficiency under suboptimal lighting conditions. NeoGreen also stands out for its approach to quality and repeatability - modules from this line are associated with **zero-carbon certified factories**, which is significant for companies reporting ESG metrics. This makes it an excellent choice for residential and commercial rooftops, carports, and installations where aesthetics, durability, and predictable yield matter. ## Notable figures - Module efficiency of 21.3% is 0.6pp below average for \*\*N-type 400-450W\*\* panels (median: 21.9%) - 212.7 W/m² power density is 5.6 W/m² below \*\*N-type 400-450W\*\* median (218.3 W/m²) - requires larger installation area - At -0.29%/°C, hot weather performance is typical for \*\*N-type 400-450W\*\* panels - Weight of 24.5 kg is 2.5 kg above \*\*N-type 400-450W\*\* median (22.0 kg) - verify structural support - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface ## Questions ### What is the HOT 3.0 technology in the Jinko Solar NeoGreen 54HL4R-BDB panels and is it worth the premium? HOT 3.0 is Jinko Solar's proprietary optimization layer built on top of N-type TOPCon cells. It delivers a lower annual degradation rate, better output at elevated cell temperatures, and higher energy yield under partial shading or overcast sky conditions. For system owners, this means more predictable generation over the full 30-year power warranty period, directly improving the LCOE of the installation. ### What warranties does the Jinko Solar NeoGreen 54HL4R-BDB series carry? The NeoGreen 54HL4R-BDB includes a 25-year product warranty covering manufacturing defects and workmanship, plus a 30-year linear power warranty guaranteeing at least 87.4% of rated output after three decades of operation. The extended power warranty is among the longest in the residential and commercial PV segment and is a key input when calculating system LCOE. ### Does the bifacial design of the NeoGreen 54HL4R-BDB make sense on a standard pitched roof with dark tiles? On a pitched roof with dark-colored tiles, rear-side irradiance is limited, so bifacial gain typically stays in the 3–8% range. However, the dual-glass construction independently improves moisture resistance and mechanical durability regardless of bifacial performance. Maximum bifacial benefit is realized in carport or elevated ground-mount applications over light-colored surfaces. ### What is the peak power output of the NeoGreen 54HL4R-BDB series, and can it fit on a small roof? The top variant reaches 450 Wp within a compact 1762×1134 mm footprint. N-type TOPCon cells push module efficiency to approximately 22–23%, meaning a higher total system wattage can be fitted into the same roof area compared to older PERC-based modules. This makes the series especially practical when available roof space is limited. ### Are the Jinko Solar NeoGreen 54HL4R-BDB panels suitable for a carport or pergola structure? Yes — the dual-glass construction and bifacial cell architecture make the NeoGreen 54HL4R-BDB a strong fit for carport and canopy applications. The glass back sheet delivers a clean all-black aesthetic, while light reflected from a pale parking surface contributes measurable rear-side generation. Note that glass-glass modules are slightly heavier than glass-backsheet alternatives, so structural load capacity should be verified during design. ### Is Jinko Solar a reliable manufacturer and is the NeoGreen series available outside China? Jinko Solar is consistently rated as a Tier 1 manufacturer by BloombergNEF and has a long track record of supplying European markets. The 54HL4R-BDB (NeoGreen) series is actively distributed through European and Polish PV wholesale channels. Jinko Solar also operates zero-carbon certified factories, which is relevant for corporate buyers tracking Scope 3 emissions as part of ESG reporting. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/1827613081681d7c50a4db2-393efd35f659.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Maxeon SPR-MAX7-475](https://comparepv.com/panel/maxeon-spr-max7-475) | 475 W | +50 W, +2.7 pp, +10 yr warranty | | [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 | +40 W, lighter, +2.5 pp | | [JA Solar JAT54S40-475/LR](https://comparepv.com/panel/ja-solar-jat54s40-475-lr) | 475 W | +50 W, lighter, +2.5 pp | | [Tongwei TWMNH-48HW475](https://comparepv.com/panel/tongwei-solar-twmnh-48hw475) | 475 W | +50 W, +2.5 pp | | [Astronergy CHSM48RN(DG)/F-BH-475](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm48rn-dg-f-bh-475) | 475 W | +50 W, +2.5 pp | | [AIKO AIKO-A475-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a475-mce54mw) | 475 W | +50 W, lighter, +2.5 pp | | [AIKO AIKO-A475-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a475-mah54mw) | 475 W | +50 W, lighter, +2.5 pp | | [Jinko Solar JKM420N-54HL4R-BDV](https://comparepv.com/panel/jinko-solar-jkm420n-54hl4r-bdv) | 420 W | Lighter, -0.2 pp | | [Jinko Solar JKM430-455N-54HL4R-B-F8-EN (430W)](https://comparepv.com/panel/jinko-solar-co-ltd-jkm430-455n-54hl4r-b-f8-en-430w) | 430 W | Lighter, +0.2 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +85 W, cooler, +3.7 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +70 W, lighter, +3.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +80 W, cooler, +3.4 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +65 W, lighter, +3.2 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +75 W, cooler, +3.2 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +75 W, lighter, +3.2 pp | --- Source: https://comparepv.com/panel/jinko-solar-eu-jkm425-450n-54hl4r-bdb-g4-425w-class Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
