Jinko Solar N-Type Bifacial 455 W (48HL4M-BDV-Z2)
Jinko Solar N-Type Bifacial 455 W (48HL4M-BDV-Z2)
A bifacial dual-glass module built on N-type TOPCon cells, compact and light enough for two installers to handle on a pitched roof, a carport canopy or a ground-mounted row. Its clear rear face collects the light bouncing off the surface below, adding roughly a tenth again to the day's harvest over bright ground. Glass on both sides, an anodized aluminium frame and certified snow and uplift loading keep it producing through decades of weather.
Key Features
- Two working faces, one panel — The clear rear glass turns light reflected off the roof or ground into extra output, worth about a tenth again on bright surfaces.
- Holds its output when the roof is hot — N-type TOPCon cells give up less power as temperatures climb, so summer afternoons stay productive.
- Built for weather, not for the showroom — Glass front and back, an anodized frame, an anti-PID guarantee and certified resistance to salt mist and ammonia for coastal and farm sites.
- Starts earlier, finishes later — Fine multi-busbar cells collect current more evenly and work better in weak light, stretching the productive hours at both ends of the day.

FAQs
How much extra energy does the bifacial back really give me?
It depends on what sits beneath the panel. The rear face converts light at about 80% of the front's efficiency, and under the published bifacial test conditions the module measures roughly 10-11% above its front-only rating. Light gravel, a white membrane roof or a raised ground mount give the most; a dark roof sitting flush to the tiles gives the least.
What warranty comes with the panel?
15 years on the product itself against manufacturing and material defects, and 30 years on performance: no more than 0.40% loss in the first year, with 87.4% of the rated output still guaranteed in year thirty.
How big and heavy is it, and will it suit my mounting rails?
Each module measures 1762 x 1134 x 30 mm and weighs 24 kg - a comfortable two-person lift, and short enough to sit portrait on most domestic roofs. The 30 mm anodized frame takes standard clamps and is certified for 6000 Pa of front load and 4000 Pa of rear uplift, so it suits snowy and windy sites alike.
