Figure 1 above displays the solar output on different days. The yellow line was from August 19,2017. This line represents a nearly ideal day for solar output. The orange line was from August 21, 2017. On the 21st there was a partial solar eclipse viewed in Michigan. It was also partly cloudy, which effected the output as well. You will notice lots of spikes in the data, these are attributed to cloud cover. The data within the white circle was captured during the solar eclipse. You will notice how quickly the output drops off. If Michigan would have been in the path of "totality" you would see the power drop down to zero.
