Jinko Solar Panels

Jinko Solar JKM625/JKM630/JKM635/JKM640/JKM645/JKM650N-66HL4M-BDV-Z4C3

A dual-glass bifacial panel that also harvests the light bouncing off your roof or the ground, so the same square metres earn more.

Models Covered: JKM625N-66HL4M-BDV-Z4C3, JKM630N-66HL4M-BDV-Z4C3, JKM635N-66HL4M-BDV-Z4C3, JKM640N-66HL4M-BDV-Z4C3, JKM645N-66HL4M-BDV-Z4C3, JKM650N-66HL4M-BDV-Z4C3

Manufacturer: Jinko Solar Co., Ltd.

Application: A full-size dual-glass bifacial module built on N-type cells, made for commercial rooftops, carports and ground-mount plants rather than small domestic arrays. The clear rear pane turns light reflected off the surface below into extra production, so a pale membrane or light gravel pays back on every sunny day. Glass on both faces, an anodised aluminium frame and a sealed junction box keep it working through storms, heavy loads and salt-laden coastal air.

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

  • Both faces generate: The clear rear glass collects light bounced up off the roof or ground, output a one-sided panel simply loses.
  • Glass front and back: Two 2 mm panes in an anodised aluminium frame, certified to 5400 Pa of downward load and 2400 Pa of uplift.
  • N-type cells: Tunnel-oxide passivated contacts give up less output in the first year and keep working in dull, early-morning light.
  • Made for hard sites: Tested against salt mist, ammonia and blown sand, with an anti-PID guarantee and an IP68 junction box.

Frequently Asked Questions

How much extra does the back of the panel really produce?

The rear face is rated at 80% (plus or minus 5%) of the front's response, and under the standard bifacial test conditions the module reads roughly 10% above its front-only rating. What you actually collect depends on how reflective the surface below is and how high the panel sits above it, so white roof membrane or pale gravel gives the most, dark asphalt the least.

What warranty comes with it?

Twelve years on the product itself and thirty years on power output. The linear warranty allows no more than 1% loss in the first year and 0.40% a year after that, which leaves at least 87.4% of the original rating still guaranteed in year 30.

What size and weight should I plan the mounting for?

Each module is 2382 x 1134 x 30 mm and weighs 32.4 kg, so it is a two-person lift and the rails need to suit a full-size 132-cell frame. Panels ship 36 to a pallet, 72 to a stack and 720 in a 40-foot high-cube container, which is the figure to use when you plan delivery and crane access.
