Bluetti has some sweet backpack solar systems on sale (and some much larger ones). https://www.bluettipower.com/products/bluetti-handsfree1-backpack-power-station?variant=46443690754267 (add the solar panels to your cart separately, the bundle isn't on sale, but the pack/powerpack is, and so is the 60 watt solar panel) (EDIT) Sale is over for now, but will resume March 10th per their website. I'm not affiliated with them. @datum@zeroes.ca
