The easy solution is an inverter connected to any truck or van's alternator. Solar does not have energy density to realistically work.

Also, contractors can mandate access to an outdoor AC outlet while they work. It’s cleaner power than ICE alternator -> inverter, and also cheaper for the contractors.

Anyway EGo has a whole day backpack battery for this use case. Not sure how heavy/sweaty/uncomfortable it is, but it lets the tools be much, much lighter than ICE versions.
