Flexible Solar Battery Chargers

 Models:

  • USF-32
  • USF-11
  • USF-5

Each UNI-SOLAR flexible solar battery charger uses United Solar's proprietary Triple Junction spectrum-splitting amorphous silicon cell design to achieve high performance. The thin-film cells are made in a patented continuous roll-to-roll deposition process on a flexible stainless steel sheet. The result is a unique, flexible, light-weight cell.

  

 Features:

  • Module Ratings -- 32, 11, 5 Watts
  • Polymer Laminated
  • Weather-Resistant
  • Three-Year Limited Warranty
  • Blocking Diodes for Battery Protection
The vinyl and foam modules are exceptionally durable. They are encapsulated in UV stabilized polmers and bonded and stitched to a cushioned backing material. The polymer encapsulation includes EVA and fluoropolymer Tefzel, a DuPont film similar to Teflon. Bypass diodes are connected across each cell, allowing the modules (excluding the USF-5) to produce power even when partially shaded.
