LONGi Solar LR4-72HBD-445M Solar Panel, 445W, MC4, 35mm Clear Frame, Glass Backsheet, 144 Half Cell Bifacial Mono-PERC, 25A Fuse, 1500VDC, 417.3W PTC

High Efficiency, Low LID Bifacial PERC with Half-cut Technology

The LONGi Solar LR4-72HBD-445M solar panel provides front side performance equivalent to conventional low LID mono-PERC panels while the Bifacial technology enables additional energy harvesting of up to 25% more from rear side of the panel. The panel has a clear, short frame without a C side which reduces the shade caused by the frame. By using an M6 standard wafer and upgrading to 9BB, LONGi has further improved the power of this module. The Hi-MO4m high efficiency, low LID with half-cut Mono-PERC cells slow power degradation making this module an excellent performer in low-light irradiance environments. Reliable glass to glass encapsulation/lamination ensures a 30 year product lifetime. The framed module provides a front and back side maximum static loading of 5400Pa / 2400 Pa respectively making them suitable for all projects, including tracking systems.

NOTE: These panels come with 1400mm cables.


Positive Power Tolerance

  • 0~+5W positive tolerance of maximum power guaranteed.
  • Using M6 standard wafer, part of assembly line upgrade to 9BB, further improving power

High Conversion Efficiency

  • Efficiency of 20.5%.
  • Half-cut cell technology enables higher power and lower hot spot temperatures because of low working current.

Excellent Performance in Low Irradiance

  • Unique parallel connection design for more energy yield in case of shading.
  • Outstanding power output in low irradiance conditions, such as dawn, dusk and cloudy days.

Bifacial Technology

  • Enables additional energy harvesting from the rear side of up to 25%.


  • The Anti-PID solar cell processing techniques and encapsulating material make these ideal for installation in hot and highly humid areas.
  • 1st year degradation of less than 2%

Adaptability to the Harsh Environments

  • Excellent anti-salt mist and anti-ammonia capability make these adaptable to harsh seaside environments.

Well Designed

  • Great pressure resistance with the ability to bear 2400Pa wind load and 5400Pa snow load.
  • Robust 35mm frame
  • Split junction box supporting 1500V systems and with 1400mm cables
  • 8 mounting holes for more mounting flexibilty and also with 400mm distance to match the horizontal single axis tracker
  • Glass/glass lamination ensures a 30 year product lifetime with annual power degradation < 0.45%


  • 12-year product warranty and 30-year linear warranty.
  • Certified to UL 1703, IEC 61215 and IEC 61730
  • Manufactured in an ISO 9001/14001 certified facility.
