Make the most out of solar energy with VoltX's handiest solar panels. The VoltX 12V 200W Mono Solar Blanket is designed for high portability with a foldable form, so you won't have to cart around a full-sized panel during travels. It has an outstanding efficiency rate of up to 23% for maximum output, thanks to the combination of monocrystalline solar cells and advanced PERC technology. PERC stands for "Passivated Emitter and Rear Contact" and works by adding extra layers to the solar cells, helping it perform better even in low-light conditions.
