Charging Systems semi flexible solar panel,or flexible solar panel are mostly made by ETFE surface,the raw material is from Japan.Solar cell is either from SunPower Maxeon cells or conventional mono-crystalline solar cells,all with cell efficiency high from 20.4% to 23.7%.Pre drilled eyelets in the corner with Stainless grommets, easy installation
-With SunPower Back Contact Cells with a higher-than-average 22.6% to 24% efficiency.
-Lightweight and Corrosion resistance. No glass or frame and only 3mm thick；With ETFE Surface
- Flexible and Better heat resistance the panel can also be bent and fixed to follow a smooth curve of 30 degrees max.-Better heat resistance to keep efficiency
-Weak light tolerance to work well under the weak light
-Low cracked cells impact-ion
-High construction efficiency
-Great flexibility to be applied on irregular surface
