Jinko Solar Panel 620W Bifacial Dual-Glass Solar Panel JKM615N-66HL4M-BDV

Jinko Solar Tiger Neo 620W N-Type Bifacial Solar Panel

The Jinko Solar Tiger Neo JKM620N-66HL4M-BDV is a high-performance 620W N-type TOPCon bifacial photovoltaic module designed for modern solar power systems.

Built with advanced N-type monocrystalline cells, JinkoSolar’s HOT 3.0 technology, SMBB current-collection technology, and a durable dual-glass structure, this panel delivers high conversion efficiency, dependable low-light performance, reduced degradation, and stable long-term energy production.

Its bifacial design allows the module to generate electricity from both the front and rear surfaces. Direct sunlight produces power through the front side, while reflected light reaching the rear side can provide additional energy, depending on the mounting arrangement and site conditions.

Main Benefits

• Lower LID and LeTID degradation
• Better low-irradiance performance
• Stable long-term power generation
• Improved performance in high temperatures
• Reduced risk of PID-related degradation
• Higher overall energy yield

JinkoSolar’s HOT 3.0 technology improves cell efficiency and reliability, while SMBB technology enhances light trapping and electrical current collection.

Bifacial Dual-Sided Power Generation

The bifacial design enables the module to produce energy from sunlight reaching both sides of the panel.

The datasheet specifies a bifaciality coefficient of approximately 80% ±5% for maximum power and current. Actual rear-side gain depends on:

• Ground or roof reflectivity
• Mounting height
• Panel tilt angle
• Row spacing
• Rear-side shading
• Installation orientation
• Environmental conditions

Under the datasheet’s bifacial test conditions, the 620W module can produce approximately 685W of total output.

Durable Dual-Glass Construction

The solar cells are protected by 2.0mm anti-reflective front glass and 2.0mm heat-strengthened rear glass.

This dual-glass construction provides enhanced resistance against:

• Moisture and humidity
• Temperature changes
• Mechanical stress
• Harsh outdoor environments
• Long-term environmental exposure

The module also includes an anodised aluminium-alloy frame and an IP68-rated junction box for dependable outdoor operation.

Excellent High-Temperature Performance

The module has a maximum-power temperature coefficient of -0.29% per °C, helping reduce output losses when panel temperature increases.

Temperature Characteristics

• Temperature coefficient of Pmax: -0.29%/°C
• Temperature coefficient of Voc: -0.25%/°C
• Temperature coefficient of Isc: +0.045%/°C
• Operating temperature: -40°C to +70°C

This makes the panel suitable for hot and sunny regions where photovoltaic modules frequently operate above standard laboratory temperatures.
