PowerShield PV325

The PowerShield PV325 is a reflective white material that protects photovoltaic (PV) solar cells, and all their sunlight-to-electricity conversion components, from such tough conditions as humid environments. PV modules typically have a 25-yr lifespan and must serve as a reliable energy source that offsets high-peak electrical demands and costs. PowerShield has a five-layer design that includes two outer protective layers based on ethylene-chlorotrifluoroethylene (ECTFE) fluoropolymer film and a core polyethylene terephtalate (PET) layer, as well as two inner bonding layers of proprietary adhesive materials. It provides a suitable alternative to the polyvinyl-backed materials commonly used as coatings today.
