No! those are monthly totals for the various years! A good day for me here is 13 kWh.
A good way to look at production is total energy produced divided by the rated power of the panels. So, for a sunny day production of 13.3 kWh divided by 2.17 kW I get 6.13 hours of rated production. Of more interest is the annual total divided by days and rated power. For 2016 I got:
3227 kWh/365 days = 8.84 kWh/day average
8.84 kWh/2.17 kW = 4.07 hours, which is pretty good for my latitude, 38ºN, and climate zone (mountain snowbelt; lots of clouds in the mountains).
This is a good way to compare the overall production of a system to installations in other geographic areas.
