Yesterday was my systems 2 year anniversary and I did some quick figuring. It's produced 17983 KWH which is 7-8% more than predicted and it's saved me $2928.56 which is roughly 11% of the total investment and 17% of the investment after tax credits. Much better than my .08% IRA.
With the 2 raises my utility has taken in that time I anticipate a better return in the future. Still planning an additional 4-5K system to help in the winter months.

    Congratulations! My 6500w system went active Oct 28, 2013, and I'm looking forward not only to payback but also achieving Net 0 for our household energy use. PVWatts predicts my system at 9900 kwh/year. Nov-Dec were at about 65%, Jan at 85%, and Feb will end at about 112% which will erase the Jan deficit. In these 4 worst months of the year in our area, the system payback already is beating 1 year CD rates.
