Lots of Watts

Yesterday was so clear and cool that I think the charts from my house might represent an ideal system maximum for March 17th at this location. March 16th, the day before yesterday, was almost identical.

This chart reveals that night time usage runs around .5 kWh.  That’s got to be phone chargers, DVR, and some other “phantom” loads from various small electronic devices that are plugged in.  The increase in usage just before sunrise is my irrigation system coming on.

The percentage of total electricity used from my solar panels was 108.  Yesterday and the day before the totals generated for both days were exactly 24.7 kWH. That’s why I think this is a good measure of the maximum my system can generate under ideal conditions in mid-March.  Because of differences in my usage, there is a slight difference in the percentage generated for yesterday and the day before.

 

 

 

The last ten days are shown below in both graphic and tabular form. So far, we have had three 100 percent plus days and one 90 percent plus day.
