Jinko Solar JKM645/JKM650/JKM655/JKM660/JKM665/JKM670N-66QL6-BDV-L-AntiDust-F1

A dual-glass bifacial panel that works on both faces and sheds dust on its own, so long rows keep earning through hot, dusty seasons.

Models Covered: JKM645N-66QL6-BDV-L-AntiDust-F1, JKM650N-66QL6-BDV-L-AntiDust-F1, JKM655N-66QL6-BDV-L-AntiDust-F1, JKM660N-66QL6-BDV-L-AntiDust-F1, JKM665N-66QL6-BDV-L-AntiDust-F1, JKM670N-66QL6-BDV-L-AntiDust-F1

Manufacturer: Jinko Solar Co., Ltd.

Application: An N-type bifacial module for large rooftops, commercial sheds and ground-mounted farms, where light bouncing off the roof or the ground is picked up by the back face and turned into extra kilowatt-hours. Glass on both sides and an anodised aluminium frame stand up to heavy snow, wind pull and salty or dusty air, while a self-cleaning surface and a sealed junction box keep output steady between service visits.

Figures on this page are the manufacturer's own, measured at the test conditions the datasheet states — they do not change by country. What changes is the approval that has to be met before the unit is energised: in Yemen that is Public Electricity Corporation (PEC), Ministry of Electricity and Energy. Confirm the grid code, import requirements and any local certification with them, or with us, before you order.

Key Features & Technical Highlights

Two working faces: The back face converts light reflected off the roof or ground, adding output the front alone would miss.
Dust slides off: A reshaped frame and self-cleaning glass stop dust settling along the edges, so yield holds between washes.
Built for rough weather: Glass on both sides and an anodised aluminium frame are certified for heavy snow at the front and strong wind pull at the rear.
Ages slowly: The cell metallisation and encapsulation are made to resist PID, LID/LeTID and UV ageing, the losses that quietly shrink an old array.

Frequently Asked Questions

How much extra energy does the back of the panel actually give?

The rear face is rated at 85% (plus or minus 5%) of the front. On the datasheet's bifacial rating, with modest light returning off the ground, each panel measures about 11% above its front-side rating; over a bright white roof or light gravel the gain is larger, over dark ground smaller.

What warranty comes with it?

Twelve years on the product itself and thirty years on output. The guarantee allows at most 1% loss in the first year and 0.35% a year after that, so the panel is still promised 88.85% of its day-one power in year 30.

What size and weight should I plan the mounting around?

Each panel is 2382 x 1134 x 30 mm and weighs 32.5 kg, in an anodised aluminium frame certified to 5400 Pa of load at the front and 2400 Pa at the rear. Panels ship 36 to a pallet, two pallets to a stack.
