I was in the penumbra, and around here I would say the entire event took an hour and a half, from “any of the sun at all is covered” to “none of the sun at all is covered.” I’m sure our local solar panels did dip in output, probably to the point of producing no useful power for several minutes as it got noticeably darker.
If it really was GW, then just multiply the 30 with time the sun was covered, and boom, you have GWH. I don’t think it was even close to an hour.

I see, given the worst case scenario of 1.5h coverage, with the average of 50% coverage, gives about 30*1.5=22.5 GWH.
