Jinko Solar N-Type Bifacial 670 W SafetyKing
Jinko Solar N-Type Bifacial 670 W SafetyKing
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.
Key Features
- 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.
- Holds up in the heat — Output falls only 0.26% per degree above test temperature, and the module is rated to run from -40 to +70 degrees.
- Top fire classification — Carries a Class A IEC fire type test report, the highest rating the standard awards.
- Built for hail and wind — Tested against 55 mm hailstones and certified to 7000 Pa of front-side and 5000 Pa of rear-side load.

FAQs
How much extra energy does the bifacial back side actually give?
The rear face works at 85 plus or minus 5% of the front's efficiency. Measured at Jinko's bifacial conditions, with 135 W per square metre reaching the back, the module reads about 12% above its front-only rating. The real gain depends on what sits underneath: pale gravel, white membrane or a raised ground mount deliver it, dark asphalt gives back very little.
What warranty comes with the panel?
Twelve years on the product itself and thirty years of linear power output. Jinko warrants at least 88.85% of the rated power still being produced in year thirty.
What are the dimensions and weight for mounting?
Each module measures 2382 by 1134 by 30 mm and weighs 40.5 kg in an anodised aluminium frame, so plan on two people per panel on a roof. Shipping goes 36 pieces to a pallet, two pallets to a stack, and 576 pieces in a 40 ft high-cube container.
