20W 12V Semi-Flexible Monocrystalline Solar Panel for 12V
The panel uses a more expensive material (imported from Japan) called ETFE (Ethylene Tetrafluoroethylene) versus PET (Polyethylene terephthalate). The ETFE film layer absorbs light better with less reflection leading to more power per square inch.
Made of Aluminium back sheet. The ETFE material bonded with the aluminium back sheet makes a stronger panel than a cheaper PET film one with less chance of cracking or water intrusion.
Highly stain-resistant and easily gets cleaned by the rain.
Highly resistant to seawater corrosion.
Waterproof and highly resistant to the harsh operating conditions of a marine environment.
The Features of Lensun Semi-flexible Solar Panels: Thin and Semi-flexible Panels Ultra lightweight and durable High Stain Resistant, Easy to Clean High Transmission offer excellent efficiency Longer life, Ageing resistance Resistance to seawater corrosion High flame retardancy, Safe installation
