At 1887 kWh, August 2015 was the highest August to date, even factoring in the array additions last year. It beat out 2012, which equates to ~1852 kWh assuming it were 28% larger.
The peak production day last month was August 16 at 78.4 kWh, which was just shy of last year's August record on July 15, 2014 at 79.1 kWh.
Below are all our numbers for 2011, 2012, 2013, 2014 and 2015 along with the PVWatts predictions for the old array (PVW42: good through June 2014) and the new array (PVW54: good starting with July 2014):
Since installation, our system has produced 63.828 MWh as of the end of August 2015.
Net grid consumption since August 2011 (when PV was turned on permanently) has been 12.5 MWh. Solar production during this period was 63.0 MWh. Total consumption equals 75.5 MWh. Solar has provided 83% of that total.
P.S. I split the "code" block into two parts since I noticed that the new forum has been adding scroll bars to my table.
