LONGi Hi-MO X10 LR7-72HVD 645M Solar Panel: Ultimate Power and Efficiency with Advanced BC-Cell Technology

The LONGi Hi-MO X10 LR7-72HVD 645M solar panel sets a new benchmark in photovoltaic technology by combining outstanding power output with cutting-edge BC-Cell (Back Contact) design. Engineered for maximum energy yield, superior durability, and sleek aesthetics, this panel is ideal for residential, commercial, and utility-scale solar projects demanding the highest efficiency and reliability.

Exceptional Power Output and High Efficiency

Delivering a remarkable 645 Watts (W) maximum power output, the LR7-72HVD 645M ranks among the most powerful panels in the market today. This superior wattage reduces the number of panels needed to generate your desired energy, optimizing installation space and reducing overall system costs.

With an impressive 23.9% module efficiency, this panel transforms nearly one-quarter of the sunlight it receives into clean, usable electricity. This efficiency level is crucial for installations where roof or land space is limited but energy demands are high.

Innovative BC-Cell (Back Contact) Technology

The backbone of the LR7-72HVD 645M’s performance is its BC-Cell back contact technology, which relocates all electrical contacts to the rear of the solar cells. This innovative design offers multiple advantages:

• Enhanced Light Absorption: Without metal contacts on the front surface, more sunlight reaches the photovoltaic cells.

• Reduced Shading and Power Loss: The absence of front contacts reduces shading effects, thereby boosting energy output.

• Improved Durability and Longevity: Back contact design minimizes hotspot formation, prolonging the panel’s lifespan.

• Aesthetic Appeal: The smooth front surface provides a clean, uniform look favored by homeowners and businesses alike.

Precise Electrical Parameters for Optimized Energy Production

The LR7-72HVD 645M operates with an Open Circuit Voltage (Voc) of 54.10 Volts and a Short Circuit Current (Isc) of 14.97 Amperes, ensuring it can handle substantial power levels safely and efficiently.

At the Maximum Power Point (MPP), the voltage stands at 44.96 Volts with a current of 14.35 Amperes—these values are essential for system designers to optimize inverter and overall system performance.

Dimensions and Weight for Efficient Handling and Installation

The panel measures 2382 × 1134 × 30 mm, providing a large surface area for maximum sunlight capture. Despite its size, it weighs 33.5 kg, which is manageable for installation teams and compatible with most mounting systems.

Versatile Applications Across Multiple Sectors

• Residential Solar Systems: High efficiency and power output mean fewer panels, saving space and cost.

• Commercial and Industrial Installations: Reliable, high-performance energy solutions for business energy needs.

• Utility-Scale Solar Farms: High wattage modules that maximize land-use efficiency.

• Off-Grid and Hybrid Systems: Robust, dependable power generation in remote areas.

Durable Design for Long-Term Reliability

LONGi’s rigorous manufacturing standards ensure that the LR7-72HVD 645M withstands harsh environmental conditions such as strong winds, heavy snow, and temperature extremes. This durability guarantees stable energy production year after year.

Environmentally Responsible Energy Production

By choosing the LR7-72HVD 645M, users support global sustainability goals by decreasing reliance on fossil fuels. The panel is manufactured with eco-friendly processes and meets international standards for safety and environmental impact.

Easy Installation and Maintenance

The design facilitates straightforward installation with standard mounting hardware. The back contact technology also reduces potential failures, minimizing maintenance needs to simple cleaning and inspections to sustain optimal performance.
