Description

LONGi Hi-MO 7 LR7-72HGD-620M 620W Bifacial Solar Panel
The LONGi Hi-MO 7 LR7-72HGD-620M is a premium 620W bifacial dual-glass solar panel engineered for high-capacity commercial, industrial, and utility-scale photovoltaic systems.

Built using LONGi’s advanced HPDC cell technology, the module delivers high conversion efficiency, excellent bifacial performance, reduced temperature-related losses, and reliable long-term power generation. Its high-output design helps reduce the number of panels required for large solar projects while maximising energy production from the available installation area.

High 620W Power Output
The LR7-72HGD-620M provides a rated maximum power output of 620W with a module efficiency of 23.0%.

Electrical Performance at STC
Rated maximum power: 620W
Module efficiency: 23.0%
Voltage at maximum power: 44.33V
Current at maximum power: 13.99A
Open-circuit voltage: 52.77V
Short-circuit current: 14.85A
Positive power tolerance: 0 to +3%
The high power density makes this module suitable for projects where strong system output and efficient use of mounting space are important.

Advanced HPDC Cell Technology
LONGi’s advanced HPDC cell technology is designed to provide superior module efficiency and dependable energy production.

Its half-cell configuration helps reduce operating temperature and electrical losses while improving performance under real-world conditions.

Main Performance Benefits
High power conversion efficiency
Lower operating temperature
Excellent low-light performance
Reduced temperature-related power losses
Strong long-term energy yield
Improved performance in hot climates
Stable power production throughout the day
Bifacial Power Generation
The module can generate electricity from both the front and rear surfaces. Direct sunlight is converted on the front side, while reflected light reaching the rear side contributes additional energy.

The panel has a stated bifaciality of 80% ±5%. Actual rear-side gain depends on:

Surface reflectivity
Mounting height
Row spacing
Panel tilt angle
Rear-side shading
Ground conditions
Installation design
This bifacial technology can increase total system yield compared with conventional monofacial modules when installed under suitable conditions.

Durable Dual-Glass Construction
The solar cells are protected by 2.0mm front glass and 2.0mm rear glass, creating a strong dual-glass module structure.

The panel also features an anodised aluminium alloy frame and an IP68 junction box with three bypass diodes.

Mechanical Construction
Cell orientation: 144 cells, 6 × 24
Glass: 2.0mm + 2.0mm heat-strengthened dual glass
Frame: Anodised aluminium alloy
Junction box: IP68 with three diodes
Cable cross-section: 4mm²
Dimensions: 2382 × 1134 × 30mm
Weight: 33.5kg
Excellent High-Temperature Performance
The module has a maximum-power temperature coefficient of -0.280% per °C. This helps reduce output losses as panel temperature increases, making it suitable for hot and sunny environments.

Temperature Coefficients
Temperature coefficient of Pmax: -0.280%/°C
Temperature coefficient of Voc: -0.230%/°C
Temperature coefficient of Isc: +0.045%/°C
Operating temperature: -40°C to +85°C
Strong Mechanical Load Resistance
The LONGi Hi-MO 7 module is engineered to withstand demanding environmental conditions when correctly mounted.

Maximum front static load: 5400Pa
Maximum rear static load: 2400Pa
Hail resistance: 25mm hailstone at 23m/s
This makes it suitable for exposed commercial rooftops, ground-mounted solar farms, and large-scale outdoor installations.
