Longi solar panel featureas:

• Positive power tolerance (0~+5W) guaranteed High module conversion efficiency (up to 21.5%) 
• 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
