In the month of August we produced over 1.8 MWh (Megawatt hours) of power on the farm. During the summer I expect to see some of the highest values of solar power production. But our loads have also been quite high, running the air conditioners and such. But when the loads are low, the extra solar power goes into the batteries for using later and during the night time.
We may see some completely different trends this winter with power usage. As we heat using a central wood furnace, but I also plan on growing indoors again so we shall see. And probably the wattage that comes into the panels will drop as well when the sun drops further down during the winter time.
But during late the summer, this is probably the max this array will see until next summer around June and July.
Array A production stats:
PV: 756.3 kWh
Load: 1823 kWh
Grid Import: 1104.2 kWh
Battery Charge: 232.1 kWh
Battery Discharge: 207.3 kWh
Array B production stats:
PV: 1071.8 kWh
Load: 1842.8 kWh
Grid Import: 917.6 kWh
Battery Charge: 334.7 kWh
Battery Discharge: 281.7 kWh
Totals combined for all arrays:
1828.1 kWh (1.8 MWh) produced for the month of August
As a comparison, here are some things you can power with 1828 kilowatt hours a month:
You can charge and drive an electric vehicle 5687.7 miles a month.
You can run a refrigerator for an entire month without issue.
You can do 20-40 loads of laundry a month.
You can power 25 LED light bulbs for 12 hours each day a month.
You can cut 3625 wood logs using an electric chainsaw.
You can charge a cell phone 16,216 times in a month.
You can power around 5 server racks (really depends on the servers in that rack though)
You can run 0 ASIC Bitcoin miners continuously.
disclaimer: all of the above statements were formed from answers based on queries to iask.ai... so I have no idea how accurate some of these comparisons are

I plan on doing these solar production posts once a month, as a journal and for people interested in the stats of my solar aray. Will do a September update a few days into November.
Thanks to @ksteem for inspiring me to make a post like this, along with using their posts for some good guidelines for producing my build lists. And figuring out how I want to format all of this information.
