About an hour after sunrise the v2 variable is shifted to an hour later as if it started recording at that time but the first hour is recorded at the correct time and added to the total. Here is a screen shot of the behavior. It stated on Feb 6th. This continues till sunset and the last data recorded an hour after sunset.
Here is the complete plot:
This shows the complete production for today with v2 plotted against the solar sensor on my weather station just a few feet away for the panels. v2 is offset by one hour after the first hour after sunrise until sunset. Any Idea as to what is happening? Before the 6th the solar sensor tracked very closely with the v2 values.
