LONGi Hi-MO X10 LR7-72HVD 640M Solar Panel: Leading-Edge Power and Efficiency with BC-Cell Technology

The LONGi Hi-MO X10 LR7-72HVD 640M solar panel is engineered for high-performance solar energy systems that demand maximum power output and exceptional efficiency. Featuring advanced BC-Cell (Back Contact) technology, this module offers superior energy conversion, durability, and design innovation, making it ideal for residential, commercial, and utility-scale solar installations.

Superior Power Output and Efficiency

With a maximum power rating of 640 Watts (W), the LR7-72HVD 640M is among the most powerful solar panels available today. This high wattage allows solar installers to reduce the number of panels needed for a system, saving space and lowering overall costs.

The module boasts an outstanding 23.7% efficiency, meaning it converts nearly one-quarter of sunlight into usable electrical energy. This high conversion efficiency makes it perfect for areas where roof space is limited or where maximizing energy production is a priority.

Breakthrough BC-Cell (Back Contact) Technology

The hallmark of the LR7-72HVD 640M is its BC-Cell back contact technology, which relocates all electrical contacts to the back of the solar cells. This design brings several benefits:

• Maximized Light Absorption: No front-side metal contacts mean more sunlight hits the solar cells directly.

• Reduced Shading Loss: The absence of front contacts decreases shading effects, enhancing output.

• Improved Durability: Back contacts reduce hotspots and enhance panel lifespan.

• Sleek, Uniform Appearance: The panel surface looks clean and modern, appealing to consumers seeking aesthetics alongside performance.

Precise Electrical Specifications

This module features an Open Circuit Voltage (Voc) of 53.90 Volts and a Short Circuit Current (Isc) of 14.94 Amperes, indicating its capacity to handle high voltage and current safely.

At maximum power point (MPP), the voltage is 44.76 Volts with a current of 14.30 Amperes, essential metrics for system designers optimizing power electronics and system layout.

Optimized Size and Weight

The LONGi LR7-72HVD 640M measures 2382 × 1134 × 30 mm, providing a large surface area to capture sunlight efficiently. Despite its size, the panel weighs only 33.5 kg, making it relatively easy to handle and install compared to similar high-power panels.

Applications Across Sectors

• Residential Solar Systems: Ideal for homeowners wanting to maximize solar output without sacrificing space.

• Commercial & Industrial Installations: Provides robust power solutions for businesses and factories.

• Utility-Scale Solar Farms: High wattage and efficiency make it perfect for large solar farms seeking maximum land-use efficiency.

• Hybrid & Off-Grid Systems: Reliable power in remote or off-grid locations.

Robust Durability and Long-Term Reliability

Designed to withstand diverse environmental challenges, the LR7-72HVD 640M offers superior resistance to high winds, heavy snow loads, and temperature fluctuations. LONGi’s stringent manufacturing standards and quality control ensure this panel delivers stable performance year after year.

Eco-Friendly and Sustainable

By choosing the LONGi Hi-MO X10 LR7-72HVD 640M, users contribute to reducing carbon footprints and promoting clean energy adoption globally. The panel’s eco-conscious manufacturing and recyclability align with green energy initiatives and regulatory requirements worldwide.

Installation and Maintenance

The panel’s large but lightweight design allows for efficient installation using standard mounting hardware. Its back contact technology reduces potential failures and makes maintenance straightforward — mainly periodic cleaning to remove dust and debris.
