I installed my own 10.125KW system 45 225W REC Solar REC225PE-US panels with Enphase mirco inverters. 7 panels face south, 26 face West, 12 face East.
The system officially went on-line 11-2-2010. The first year I made 8,842KWhrs. I also have a EcoDog energy monitoring system installed, I used about 3,300KWhrs so I have a lot of excess energy I can use to charge my Leaf.
Total install cost (I did it all myself) was about $38K.

Leaf delivery is due end of June, looking forward to a 100% SOLAR driving solution.
