Jinko Solar EU-JKM425-450N-54HL4R-BDB-G4 (435W class)
Middle of its segment, heavy for its output
The Jinko Solar 54HL4R-BDB (NeoGreen) series was designed with investors in mind who wish to combine the all-black aesthetic with tangible energy gains. 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.
Ranking
Signals from the data
Residential and commercial.
Weight-limited structures.
Bottom 15% of the N-type 400-450 W segment, against a median of 51.2.
- Efficiency of 21.8% matches the N-type 400-450W median
- At 217.7 W/m² power density, roof space requirements are typical for N-type 400-450W panels
- Temperature coefficient of -0.29%/°C matches the N-type 400-450W median
- Weight of 24.5 kg is 2.5 kg above N-type 400-450W median (22.0 kg) - verify structural support
- 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces

Datasheet charts
Measured curves published by Jinko Solar in this model's datasheet. A chart carrying a wattage was measured on that variant alone - only the ones that describe 435 Wp appear here. The rest cover the whole series.
Simulations
Degradation from this panel's own datasheet figures. No inverter, soiling or shading losses.
Model: bifaciality × albedo × 0.6 view factor. A first-order estimate, not a yield simulation.
