Solar production affected by the Eclipse

The Eclipse of August 21 had an effect on solar power production on our systems.  It was interesting to see that just before the eclipse, power production was at its peak. Then as the sun was blocked, production dropped off by as much as 80%. Graphically there was a beautiful curve that slowly dipped and then rose back to peak production. Ridgway experienced about an 85% eclipse, so the landscape was still lit by daylight, only sightly darker than normal, but solar production was drastically reduced. I envision the sun as a faucet pouring a flow of Photons to earth and the eclipse acting as a valve to reduce that flow. Truly an amazing phenomenon.
