In my case, I added enough panels to lower my consumption to less than 125 KWH per month on average. Now my highest bill for a two month period was close to $500 pesos and my smallest bill was $81 pesos.
I would recommend that you get a large enough inverter (DC to AC) to allow you add a panel or four, should that be necessary to lower your bill to a few hundred pesos per billing period. Why? Because it turned out that in my case, I was using a little more electricity than anticipated and I was able to add an additional 2 panels. (Without needing to upgrade to a larger inverter.)
