Key Features of LONGi Hi-MO 7 LR8-66HGD-615M
⚡ 615W Ultra-High Power Output
With a rated output of 615W, this panel provides high power generation from a single module. Higher-wattage panels can help reduce the total number of modules required for a target system capacity and optimize installation space.
☀️ Bifacial Solar Technology
The LONGi Hi-MO 7 can generate electricity from both the front and rear sides of the module.
The additional energy produced from the rear side depends on factors such as ground reflectivity, mounting height, installation angle, shading, and overall system design. Under suitable conditions, bifacial technology can provide a meaningful increase in total energy yield.
🧪 Advanced HPBC Cell Technology
LONGi’s HPBC (Hybrid Passivated Back Contact) cell architecture is designed to improve light utilization and reduce front-side electrical shading, helping achieve high module efficiency and strong power output.
📈 Up to 21.7% Module Efficiency
With module efficiency of up to approximately 21.7%, the LR8-66HGD-615M is designed to produce more electricity from available sunlight while making efficient use of installation space.
🔲 132 Half-Cut Cells
The panel uses 132 half-cut cells in a 6×22 configuration. Half-cut technology helps reduce internal electrical losses and can improve module performance and reliability under certain shading conditions.
🌡️ Excellent Temperature Performance
With a low power temperature coefficient, the panel is designed to minimize power losses as module temperature increases—an important advantage for solar installations operating in Bangladesh’s hot summer conditions.
🌥️ Strong Low-Light Performance
The Hi-MO 7 is designed to maintain useful energy generation under lower irradiance conditions, including cloudy weather, mornings, and late afternoons.
🛡️ Double Glass Construction
The module uses 2.0mm heat-strengthened glass on both the front and rear sides. Double-glass construction provides enhanced protection against environmental stresses and can improve resistance to moisture, PID, micro-cracks, salt mist, and ammonia.
💪 High Mechanical Load Resistance
The panel is designed for significant mechanical loads, with specified resistance of up to:
- Front: 5400 Pa
- Rear: 2400 Pa
This provides additional reliability when the module is properly installed using a suitable mounting structure.
🔌 IP68 Junction Box & MC4-Compatible Connector
The IP68-rated junction box provides strong protection against dust and water ingress. MC4-compatible connectors make integration with compatible solar system components convenient and secure.
📉 Low Annual Degradation
The panel is specified with a 0.35% annual degradation rate after the first year, helping maintain strong energy production over its long operating life.
Benefits of LONGi Hi-MO 7 615W Bifacial Solar Panel
More Energy From Every Panel
The combination of 615W power output, high efficiency, and bifacial technology provides an excellent opportunity to maximize energy generation from each installed module.
Better Use of Limited Space
High power density is particularly useful for commercial and industrial rooftops where available installation space may be limited.
Increased Bifacial Energy Yield
The transparent rear side allows the module to utilize reflected sunlight. Ground surfaces with higher reflectivity and properly designed mounting structures can improve bifacial energy gain.
Long-Term Durability
Double-glass construction provides additional protection against environmental conditions, making the panel suitable for demanding outdoor solar installations.
Lower Energy Cost Over the System Lifetime
Higher energy production, high power density, and long-term performance can contribute to a lower Levelized Cost of Energy (LCOE) when the overall solar system is properly designed.
Suitable for Bangladesh’s Climate
The panel’s temperature characteristics, weather-resistant construction, and durability make it well suited for Bangladesh’s hot, humid, and changing environmental conditions.
