Afghanistan was a testbed for this technology because remote bases were often extremely expensive to maintain if running off of generator power. The cost of fuel was astronomical since it had to be ferried in by helicopter.

I have a friend who sells containerized solar+wind+battery power systems, which is pretty handy in places where there's no grid. But still, given that PR does have a grid, repairing it plus sending in diesel for hospitals/cell cites is probably more cost-effective than sending in containerized solar now.
