There are off the shelf options for emergency power supply, even with the option to add small mobile solar-panels. But they tend to be really expensive.
For low powered laptops there are even fold-able camping solar panels that have a USB plug. I have used that to power and recharge my Pinebook Pro on some extended trips in the past. Probably also works with chromebooks and some low powered ultra-books.
If you want to try your hand at a DIY solution: the best way is to get a PicoPSU ATX power supply that can be directly connected to a 12V/24V battery. They are meant for automotive computing, but work fine with a regular battery, a cheap solar-charge controller and some panels on the roof or balcony.
I have to ask how do you like the pine book pro?
I have one of their phones but the software at the time was really under developed so it mostly sat for a few years
It is basically just another Linux laptop. Small caveats with not all software being available for ARM64, but for the most part it works fine. Contrary to the PinePhones there isn't much complicated hardware in these laptops that needs special drivers, wake on notification or other battery-optimizations.
