Good points ... "how often ..." and "partial charge" (using solar).
But think carefully "how often" you'll be doing this. You might end up with a LEAF that gets 4 mpe, but also only 20 mpg
It might be worth using the (cough!) g
as car !
If you end up with solar ... and the utility has good rates ... when you're not at the cabin (if you can get the grid connected) you can MAKE money selling to the utility ...
