About product

LONGI 445W LR4-72HPH-35 is a 144 cell module with high efficiency and low LID mono PERC cells. Half-cut Multi Busbar Technology improves performance and boosts production of the solar panel. This module has a 35mm lightweight frame resilient enough to withstand 5400Pa load and 25mm hailstones at the speed of 23 m/s.

  • 445W Power Output
  • 144 Cell, Monocrystalline, 9 busbars
  • 20.5% Module Efficiency
  • 1500 Volts Max Voltage
  • Low LID mono PERC cells
  • MC4 connectors
  • Silver frame, white back

PV Module Efficiency of up to 20.5%

LONGI 445W LR4-72HPH-35 performs at 20.5% efficiency, ensuring excellent energy yields. It is achieved due to the advanced technologies, such as M6 Gallium-doped wafers and 9-busbar half-cut cell technology.

Quality and Reliability

All LONGI panels undergo a number of stringent quality control tests. LONGI 445W LR4-72HPH-35 is designed to withstand front side maximum static loading of 5400Pa and rare side maximum static loading of 2400Pa.

Slow Power Degradation

Slow power degradation is achieved due to Low LID Mono PERC technology. First year the panel degrades <2%, and 0.55% over the next 24 years.

Enhanced Frame Design

The module’s 35 mm frame design provides easy mounting and ensures robust mechanical strength, which makes LONGI 445W LR4-72HPH-35 suitable for both roof and ground installations. This module passed rigorous ammonia and salt mist resistance tests.

25-Year Power Output Warranty

LONGI 445W LR4-72HPH-35 comes with a 12-year materials and processing warranty and 25-year warranty for extra linear power output.
