The Longi 440W solar panels offer high module conversion efficiency of up to 19.8%. The panels also provide slow power degradation (first year <2%, 0.55% year 2-25).
- Positive power tolerance: (0 ~ +5W) guaranteed.
- High module conversion efficiency: up to 19.8%.
- 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 optimisation and careful module BOM selection.
- Reduced resistive loss: with lower operating current.
- Higher energy yield: with lower operating temperature.
- Reduced hot spot risk: with optimised electrical design and lower operating current.
