This was such useful information when I was researching solar power.
Well I decided to go with Enphase micro inverters. I donít have shade but I really like the idea if one M215 fails I will be out one panels output and if it takes a month to get a replacement it is now a huge deal. ( I have bought a spare Enphase micro inverters just in case )
I bought 40 CS6P-230P Canadian Solar panels and 40 M215 Enphase micro inverters.
I did a self-install for the 9.2kw system just like the others above did.
I had to upgrade my main load center to a 225 amp panel. The out building I installed on is about 130 feet away from my house so I had to center feed my panels. 10 panels are center feed 5 and 5 all 40 panels are done this way. I also had to run a little larger wire to the sub panel to keep the voltage rise down.
Here is a link to my system

I am still using more power than I am making so I just ordered 10 more panels/ M215 so I hope that will bring me closer to net zero.

It is now 12.5 KW 54 solar panels.
Our best day so far was 04/16/14 92.31 kWh

Update 10/31/2017
Our system is paid off 4 Ĺ years. If you only take into account just power savings no others savings.
