Sounds good. You'll like the micro inverters (Enphase?). Lots of data available. 

I have a roof top array on my hay shed which offsets my winter electric bill on the waterer over there. It is interesting to compare the pay back periods on roof top, ground mount and the tracker.

Roof top has a very good payback if you've got a nice south facing roof at about a 40 degree angle which it appears you have. I calculated about 7 years here on a DIY installation. Good luck with yours.
