12.5 Kw array
Jan 2016: generated 1,290 Kwh but used 1,009 more than I made. (lots of Mini split heating and EV driving) we have used no natural gas to heat with so far.
This will take my banked power to 1,221Kwh
This is that last month to use banked power they zero us out March 1.
This is my power bill for the last 22 months. We also power our EV car just under 20k miles a year.
Other solar guys show use your numbers.
