I think the average home ownership in the US is 5-7 years. Depending on the size of your solar setup, you very well may not break even before moving for whatever reason. That said, it does make sense if you do plan to stay for 10+ years I think. As new houses get built, hopefully with requirements for solar, the housing stock will eventually all be upgraded to include some form of solar generation. I would expect the price to further come down and the majority of homes in the 1st world to have residential solar of some form within the next 30 years.
