I agree completely with your doubling up panels with E/W facing rows on the same inverter, but have you really looked at the best angle? Here is what to consider: 1) The ideal southern facing array is set to your latitude. 2) But the more East or West you go, the optimum angle is lower. 3) If you are truly East or West, then almost 20 degrees is better. 4) Do not worry about overloading your grid Inverter. 5) The MPPT algorithm in your MPPT grid-tie inverter will automatically always limite your output to the rating of that inverter. So even if you get 1.414 times more solar power at noon because both sides of the "rail" is getting sun at the same time for an hour or so, still the MPPT algorithm is only going to produce the rated power of the inverter. 6) Even though it is producing TWICE the energy because it is doing it twice as long with both the East and West rails...
