Power from both faces
The rear side works at 85% of the front's output, turning light reflected off the surface below into extra kilowatt-hours.

Solar PanelsModel JKM670N-66QL6-BDX-SafetyKing-F2
A dual-glass N-Type Bifacial 670 W SafetyKing that harvests light on both faces, so every row of the array turns more of the day into usable power.
What sets the JKM670N-66QL6-BDX-SafetyKing-F2 apart from the other 5 models in the family: Maximum Power - Pmax 670 W; Maximum Power Voltage - Vmp 42.92 V; Maximum Power Current - Imp 15.61 A; Short-circuit Current - Isc 16.34 A; Open-circuit Voltage - Voc 50.60 V; Module Efficiency STC 24.80 %; Specifications (STC) Maximum Power - Pmax 670.

The rear side works at 85% of the front's output, turning light reflected off the surface below into extra kilowatt-hours.
Output falls only 0.26% per degree above test temperature, and the module is rated to run from -40 to +70 degrees.
Carries a Class A IEC fire type test report, the highest rating the standard awards.
Tested against 55 mm hailstones and certified to 7000 Pa of front-side and 5000 Pa of rear-side load.
Built on Jinko's N-type TOPCon cells and sealed between two 2.5 mm sheets of glass, this bifacial module also collects the light bouncing off the ground or roof beneath it, adding roughly a tenth again to what the front face alone delivers. It belongs on ground-mounted plants, carports and flat commercial roofs where that reflected light is real. A Class A fire rating, 55 mm hail testing and 7000 Pa front-load certification keep it earning through weather that stops lesser panels. This model: Module Efficiency 24.80%, Maximum Power (Pmax) 670W.
