What is a good ballpark figure for the payback period of a PV system?
I am aware that this question is incredibly general question with a
bunch of parameters that can drastically effect this number, but I am
about to do some number crunching and I was hoping for a ballpark
figure (i.e. 10, 15, 20 years?).
Thanks,
Kris

15-20 years in the USA without subsidies
6-10 years in the USA with subsidies
70-80 years in Canada

Why the long period in Canada?
Is it lack of incentives? Lower utility costs? Lower solar resource?
All three?

ALl three plus honesty.
Many don't count the loss of investment funds in their missing money.
Usually you can never break even and many places.

Less sunlight.
The same would be true of northerly US states too of course.
