PHOTOVOLTAIC GLASS STUDY - Vindico PV+ - Glass solutions for increasing photovoltaic productivity (patent pending)
Vindico PV+ (patent pending) Simple Steps leading to Simply Amazing Results Increasing light transmission with anti-reflective coating Protection of the AR coating using Vindico HP, a sol-gel technology Low-soiling, easy-maintenance properties on glass and AR Reducing glass contamination and pollutants Increased energy production Durability for the lifetime of the module High Return of Investment
Problem 1: Glass corrosion begins damaging watt peak before production of photovoltaic panel even begins Glass examined at time of float production Air side/tin side 38 days later Air side/tin side untouched Atomic Force Microscope (AFM) pictures
Problem 2: Air-born contamination further reduces light transmission Contamination Takes Many Forms: Unburned Hydro-carbon Mineral Deposits/Water spots Dust All contaminants reduce light transmission All reduce Watt-peak production
