Here is a portable, modular solar panel that you can use to generate power from sunlight anywhere. The Levante 500W Origami Solar Panel is lighter than comparable foldable panels and has a rigid structure when unfolded. You simply have to plug it into your portable power station to generate power for your devices.
You can increase power output by zipping on an additional module. The origami solar panel has a cell efficiency of 23.4%. You can find it on Kickstarter.
