Product Description

LONGi 440w Mono PERC w 144 Half-cut Cells (72 cell equivalent). Silver 35mm frame, white backsheet and MC4 compatible connectors w/ 55" (1400mm) cable.

The LONGi HPH Series combines High Efficiency, Low LID Mono PERC cells with Half-cut Muti Busbar Technology to improve performance and boost production. This module series has a max system voltage of 1500V and is Fire Rated as Class C (per UL790). 35mm frames reduce weight while still providing the strength and resilience needed to rate 5400Pa for front side static loading and 2400Pa for rear side static loading.

  • Positive power tolerance (0~ +5W) guaranteed
  • High module conversion efficiency (up to 20.5%)
  • Slower power degradation enabled by Low LID Mono PERC technology: first year <2%, 0.55% year 2-25
  • Solid PID resistance ensured by solar cell process optimization and careful module BOM selection
  • Reduced resistive loss with lower operating current
  • Higher energy yield with lower operating temperature
  • Reduced hot spot risk with optimized electrical design and lower operating current
