Two faces, one panel
The rear face is rated at 85% of the front, so it keeps earning wherever the ground under the array is bright.

Solar PanelsModel JKM650N-66QL6-BDV-F2
A dual-glass bifacial panel that generates from its back face too, so bright ground beneath the array is turned into extra daily output. This model: Module Efficiency 24.06%, Maximum Power (Pmax) 650W.
What sets the JKM650N-66QL6-BDV-F2 apart from the other 4 models in the family: Maximum Power - Pmax 650 W; Maximum Power Voltage - Vmp 42.57 V; Maximum Power Current - Imp 15.27 A; Short-circuit Current - Isc 15.98 A; Open-circuit Voltage - Voc 50.26 V; Module Efficiency STC 24.06 %.

The rear face is rated at 85% of the front, so it keeps earning wherever the ground under the array is bright.
Two millimetres of glass on each side replace the usual plastic backsheet, leaving moisture and abrasion nothing to attack.
It gives up only 0.26% of its power per degree above 25 °C and is rated for service from -40 °C to +70 °C.
Qualified against PID, LID/LeTID and UV degradation, and separately against salt mist, ammonia and blown sand.
Built on Jinko's N-type cell platform and sealed between two sheets of glass rather than a plastic backsheet, this bifacial module suits commercial rooftops, car park canopies and ground-mounted farms where light bounces back off the surface below. The rear face works at 85% of the front's rating, and the frame is certified to hold 5400 Pa of downward load and 2400 Pa of uplift. Twelve years of product cover and thirty years of performance cover come with every panel. This model: Module Efficiency 24.06%, Maximum Power (Pmax) 650W.
