Jinko Solar JKM650/JKM655/JKM660/JKM665/JKM670N-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.

Models Covered: JKM650N-66QL6-BDV-F2, JKM655N-66QL6-BDV-F2, JKM660N-66QL6-BDV-F2, JKM665N-66QL6-BDV-F2, JKM670N-66QL6-BDV-F2

Manufacturer: Jinko Solar Co., Ltd.

Application: 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.

Key Features & Technical Highlights

  • 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.
  • Glass front and back: Two millimetres of glass on each side replace the usual plastic backsheet, leaving moisture and abrasion nothing to attack.
  • Keeps its output when it is hot: 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.
  • Ageing is tested, not assumed: Qualified against PID, LID/LeTID and UV degradation, and separately against salt mist, ammonia and blown sand.

Frequently Asked Questions

How much does the bifacial back face really add?

Its bifaciality is 85% (±5%), so under the datasheet's own bifacial rating — a modest 135 W/m² reflected onto the rear — each panel delivers roughly 11% more than its front-only figure. The real gain depends on how bright the surface below is and how high the row sits above it.

What warranty comes with it?

Twelve years on the product itself and thirty years on power output. First-year degradation is capped at 0.35%, and at least 88.85% of the original output is still guaranteed at year 30.

What size and weight should I plan the mounting around?

Each panel is 2382 × 1134 × 30 mm and weighs 32.5 kg in an anodised aluminium frame, certified to 5400 Pa on the front and 2400 Pa on the rear. They ship 36 to a pallet, 720 in a 40 ft high-cube container.
