The area under the curve matters more than the peak.Did you draw that symmetrical bell curve?
It only shows a peak of 8 kW though.
And this system is outputting 2K at 4 PM in Illinois, which is impressive.

its only a 10.2 KW system, so 80 % of the max is good isn't it in Feb?
Also my best day since install . Actually the past week in Illinois has been great.
I'm 6.12 kW with 18 panels facing south

My bad. I thought I read 15 and that was in my head. Yes, it is great performance for this part of the year.
I also thought the curve would be a different shape due to the split directions of the panels..
In summer if it clips which it might, not to worry, you will be producing a bunch.

You are lucky to face south! We too had a full sun day here in Massachusetts, and my production total and curve is identical to yours. Unfortunately for me I have an east/west split 12.24kwp system of 36 panels. So really only have of my system is working at a given time. So I paid twice as much for the system for the same production because of my roof orientation.
I kinda have the same issue. 1/3 of my panels face west, but for the first half of the day they are block by my house. Now they do face west so I guess better than nothing, but a lot of money for 1/2 the productionYou are lucky to face south!

Had to put them on the front side of the house. Not what I wanted to do initially looks wise, but don't mind it now.

Simple, turn the house.

@ChicagoSox How's the production today? Mine over in northeast Iowa is a tad lower today despite the sunny blue sky. There is a healthy stream of water vapor coming in from the Rockies. If you are in northern Illinois, you might have noticed a slight reduction.
