A guy in Florida quoted 48 years pay back time. I ran
the numbers for my home - over 40 years, and I pay 13
cents per kwh. A 2 kW system costs $15000. Assuming
an average of 8 hours per day of 2kW per hour, that
solar system would give me 16 kWh. I pay 16*.13 or
$2.08 for 16 kWh. Works out to 19+ years for payback,
if you don't count on mortgage payments for the system.
Add that in, and the cost of a $15000 system is
much worse - over 30,000 in a 25 year, 7% mortgage.
You have to take into account that the cost of a kWh from
the grid in 25 years will be a LOT higher too, if there
still is a grid during and after WW3 that is.

I would say that so far during WW# there is still a grid.
