My last 12 months have been about 28 megawatt hours. House is about 15,240 square feet if you also include the pool house. That is with us using air-conditioning sparingly (mostly having it off, but when it is on, it is on 77 degrees, and only in a few rooms). My goal is to be able to just leave the AC on 75. Though I have already failed at that, because my wife keeps on shutting it off.
Also I may have a Tesla in about two years. If so, that will use about 3.5 megawatts per year.
So I would like to have about 32 megawatts per year.
I used PV-Watts for each string, and guesstimated shade for each string, and I think this will produce 26 megawatt-hours the first year. So it is really not big enough.
