Jinko Solar 620-Watt N-Type Bifacial Dual Glass Solar Panel JKM620N-66HL4M-BDV; Voc49.08V, Vmp40.74V, Imp15.22A, Isc16.08A, 22.95%

The Jinko Tiger Neo JKM620N-66HL4M-BDV is a 620W N-type bifacial dual-glass solar panel built for high-performance residential, commercial, institutional, agricultural, and utility-scale solar systems. It is designed for users who need more power per panel, better long-term energy yield, and improved reliability in demanding solar installations.

Built with N-type mono-crystalline TOPCon technology, HOT 3.0 technology, SMBB cell design, bifacial power generation, dual-glass construction, and anti-PID protection, this Jinko Tiger Neo module delivers strong performance in both standard and high-yield solar system designs. The bifacial design allows the panel to generate additional power from reflected light on the rear side when installed in suitable conditions, helping improve total energy production and reduce long-term system cost.

With 620W rated output, 22.95% module efficiency, 1500VDC maximum system voltage, 35A maximum series fuse rating, and a 30-year linear power warranty, this panel is a strong choice for serious solar projects where energy yield, durability, and trusted manufacturer quality matter.

3 Things to Consider When Buying a Solar Panel

• System design and inverter compatibility: This 620W panel has a Voc of 49.08V and Isc of 16.08A at STC, so string sizing must be checked carefully against the inverter or MPPT charge controller voltage and current limits.

• Bifacial installation conditions: Because this is a bifacial dual-glass panel, rear-side gain depends on installation height, tilt angle, ground reflectivity, shading, and mounting structure. It performs best where the rear side receives reflected light.

• Handling and mounting: This is a large, heavy module measuring 2382 x 1134 x 30mm and weighing 32.4kg, so proper mounting rails, clamps, lifting, spacing, and installer handling are important.
