2 years of production with 6K system and still going strong :D

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.

Re: 2 years of production with 6K system and still going strong
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.
