One problem though... You can't mine at night
Though I joked about stealing solar panels, they won't work because of their payback time. When you have payed them off, in savings, and start getting free electricity difficulty has risen and you have to invest in more mining gear and solar panels.
So instead of just having a payback time on your ASICS, you also have it on your power source, proportional power costs without money up front, from the wall, makes more sense!
So you have to steal solar panels to make them worth while.
