JA Solar DeepBlue 4.0 Pro JAM66D45 LB 620W Bifacial Solar Panel
The JA Solar DeepBlue 4.0 Pro JAM66D45 LB 620W is a premium high-output photovoltaic module designed for commercial rooftops, industrial projects, ground-mounted solar systems, and utility-scale installations.
Built with advanced N-type bifacial cells, 16BB half-cell technology, and a durable double-glass structure, the panel provides high conversion efficiency, strong low-light performance, reduced degradation, and dependable long-term energy production.
Its bifacial design allows electricity generation from direct sunlight reaching the front surface and reflected light reaching the rear surface. Actual rear-side energy gain depends on the mounting height, surface reflectivity, row spacing, tilt angle, and site conditions.
High 620W Power Output
The JAM66D45-620/LB provides a rated output of 620W with a module efficiency of 23.0%, making it suitable for projects where high power generation and efficient use of installation space are important.
Electrical Performance at STC
Rated maximum power: 620W
Module efficiency: 23.0%
Maximum power voltage: 40.21V
Maximum power current: 15.42A
Open-circuit voltage: 48.50V
Short-circuit current: 16.13A
Power tolerance: 0 to +3%
N-Type Bifacial Cell Technology
The panel uses advanced N-type bifacial cell technology to provide excellent energy production and stable performance under different operating conditions.
Main Benefits
Lower light-induced degradation
High module conversion efficiency
Better low-irradiance response
Improved performance in high temperatures
Front and rear-side electricity generation
Stable long-term output
Bifaciality of 80% ±5%
Additional Rear-Side Power Generation
Under the datasheet test condition of 10% rear-side solar irradiation, the 620W model can produce approximately 670W of combined output.
Performance with 10% Rear Irradiation
Combined maximum power: 670W
Maximum power voltage: 40.21V
Maximum power current: 16.65A
Open-circuit voltage: 48.50V
Short-circuit current: 17.42A
Actual bifacial power gain will vary depending on the installation design and environmental conditions.
Double-Glass Construction
The solar cells are protected by 2.0mm front glass and 2.0mm rear glass, creating a strong double-glass module structure.
This construction provides enhanced protection against:
Moisture and humidity
Temperature changes
Mechanical stress
Harsh outdoor conditions
Long-term environmental exposure
Potential degradation
Excellent Temperature Performance
The panel has a maximum-power temperature coefficient of -0.290% per °C, helping reduce power losses when module temperature increases.
This makes it suitable for hot and sunny environments where solar panels regularly operate above standard testing temperatures.
Strong Low-Light Performance
The N-type cell design provides reliable generation during lower solar-irradiance conditions, including:
Early morning
Late afternoon
Cloudy weather
Hazy conditions
Indirect sunlight
This helps extend useful solar production throughout the day.
High Mechanical Strength
The module is engineered to withstand demanding environmental and structural conditions when correctly installed.
Maximum front static load: 5400Pa
Maximum rear static load: 2400Pa
Module dimensions: 2382 × 1134 × 30mm
Module weight: 33.1kg
Reliable Outdoor Operation
The panel includes an IP68 junction box with three bypass diodes and supports photovoltaic systems operating at up to 1500V DC.
Operating Conditions
