Jinko N-Type Bifacial 620 W features

Generates from both faces

Light reflected off the roof or ground reaches the glazed back and adds output, with the rear side responding at about 80% of the front.

Glass instead of a backsheet

Two 2 mm panes seal the cells, so damp, sand and UV have no soft layer to attack.

Certified for hard weather

Tested to 5400 Pa of load on the front and 2400 Pa on the rear, with salt-mist, ammonia, sand and anti-PID certification.

Keeps its power in the heat

Output slips just 0.29% per degree above 25 °C, and the module is rated to run from -40 °C to +70 °C.

About the Jinko N-Type Bifacial 620 W

A large-format dual-glass module on N-type TOPCon cells, built for commercial rooftops, carports and ground-mounted arrays where light also reaches under the panel. The glazed back face turns that reflected light into extra output — roughly a tenth more on a bright surface — without adding a single row. Two panes of glass and an anodised frame take heavy snow and storm uplift, and Jinko covers the product for 12 years and the output for 30. This model: Module Efficiency 22.95%, Maximum Power (Pmax) 620W.

Frequently Asked Questions

It depends on what sits under the array. Jinko rates the rear at 80% ±5% of the front, and at the datasheet's bifacial reference conditions (135 W/m² of rear irradiance) output rises by roughly 10%. A light roof membrane, gravel or concrete puts you near the top of that range; grass or dark asphalt gives less.

12 years on the product itself and 30 years on power output. Jinko allows 1% loss in the first year and 0.40% a year after that, which still leaves at least 87.4% of the original output in year 30.

Each module measures 2382 × 1134 × 30 mm and weighs 32.4 kg — a two-person lift on a large-format frame, so check your rail spacing and that the roof or tracker takes the span. They ship 36 to a pallet and 720 in a 40 ft high-cube container.
