Spreadsheet for first four years of operation.

I kept daily readings of my electric meter and my charge controllers for the first four years of operation.  These thousands of data points are a valuable resource for examining the performance of my system and learning its specifics.  For example, I searched all of the total generated column for a maximum value and learned that the most my system ever generated in a day was 30 kwh.  That seems like a lot but on that particular day it was only 46 percent of our energy.  It was a hot day and the house had yet to be tweaked for energy conservation.  I also had a large RV plugged in with its air conditioner running.
