This 0.6 Watt 6 Volt small solar panel is a lightweight, waterproof, solar panel produced by Voltaic Systems that has been designed for five to seven year outdoor applications. This panel will charge 1S LiIon or LiPO4 cell. The panel features high-efficiency SunPower solar cells mounted to a PCB using an SMT Process, scratch-resistant ETFE(Teflon™ ethylene tetrafluoroethylene) coating with UV-resistant EVA, and two solder pads.
But what is ETFE coating: It's considered one of the most durable fluoropolymer coatings, used widely across the chemical, power, energy production, and semiconductor industries.
It should go without saying but, for maximum power output, orient the panel towards the sun.
