SMBB Technology Excellent Anti-PID performance guarantee via optimized mass-production process and materials control. PID Resistance High salt mist and ammonia resistance. Durability Against Extreme Environmental Conditions 2400 Pa 5400 Pa Certified to withstand: wind load ( Pascal) and snow load ( Pascal). Enhanced Mechanical Load Optimized electrical design and lower operating current for reduced hot spot loss and better temperature coefficient. HOT Reduced Hot Spot Loss Low Pmax temp coefficient increases energy production
