I mean, there are parts of Alaska where for part of the year it's light non-stop for literally weeks at a time. Plus they don't have to buy them, and as solar panels are getting more efficient there will be a point where they'll be able to get almost as much as someone from a place like California.
And "I want the solar energy to power my phone too, so that I don't have to recharge it with electricity" may be the dumbest thing you've ever said in these boards, which is saying something.
