For the calender month of September, our 6.810 kW arrays made 823 kWh. Several low-light days toward the end of the month.
Will edit to post our usage based on our power bill which is always from the 19th to the 19th when it gets here in the next couple of days. We were on vacation with most of the circuit breakers in the house turned off from 6am 9/6 to 5pm 9/12, so this month should be an unusually low usage month. I even unplugged my alarm clock (and removed the backup battery) to keep from having that miniscule load. My wife, of course, thinks I get carried away....
Our consumption for last month was 317 kWh. Just because I could, I divided the total production of 27317 {coincidence} since we went live by the 1019 days {almost 2.8 years} and got an average of 26.808 kWh daily average. Also checked the percentage paid back {including the 30% tax credit}, and we are 48.949% paid back. I expect full payback in just barely over 10 years. And yes, I include any repairs or replacement items I have to buy as part of the cost equation.
