Do you keep it at "base camp" so to speak, like with the tent? Or do you wear it on the pack while hiking?

I’ve tried both, it’s way more efficient to set it up at camp facing the sun. I think for the future I’d rather just take it out during breaks and when setting up camp for the day.

I live 59°N, during the summer there’s plenty of time to both hike far and recharge batteries after setting up camp for the day.
