KSUN folding solar panels are ideal for bug out bags and other outdoor activities due to their being exceptionally portable, lightweight, durable, and efficient. Their flexibility makes for a variety of possibilities in terms of how they can be set up, throw it on a tent, hang it from a tree, backpack, or just roll it out on the ground. Most monocrystalline panels I've seen are too heavy to be thrown over shelter setups like tents, or too awkward or inefficient in variable light conditions to be effectively mounted to a backpack when mobile. The quality of KSUN’s products are second to none, always supports KSUN’s design and manufacturing technique.
