    Here is a graphic to show how the power output of my solar system dipped during the eclipse, which went to about 95% here.

    The red line show eclipse. Other power dips are clouds passing by. If you have a solar system, what did it do?

    Not much for us do to the fact that it was foggy, we normally were producing around 39kWh per day and got around 35.

    Not much really: about 4-5% less output than the previous days. I see a lot more impact from a heavy marine layer, sometimes over 50%.

    System #1:
    8/20 = 18.2kWh
    8/21 = 16.5kWh

    Funny you should ask, since I was so amused by what happened with mine in southern Colorado (~90% sun coverage), I threw it into my blog post about the eclipse:

    (the afternoon dip is due to clouds rolling in.)
