Newly Black ETFE flexible solar panel solar cell 20w solar panels ETFE Coating battery charger 12V solar battery

 

20W 18V ETFE Semi-Flexible Monocrystalline Solar Panel with  Connectors for 12V Charge Battery on Boats, Motor 

 

 

Technical Specification

 

High efficiency Flexible(bendable) solar panel

High efficiency bendable solar module adopts the highest efficiency cell in the world from the USA, with efficiency up to 20% or higher,

which enable 25-30% higher power generation than the conventional PV modules at the same size.

 

By adopting the back contact technique, the cell can be coated with flexible materials and finally forms a high efficiency flexible solar panel.

This kind of solar panel can be widely used in the field of Electric Golf Car, Patrol Car, Travel Tourism Car, Yacht, Roof Power generation, Backpack, Tent and so on.
