Today’s solar eclipse took a healthy bite out of our solar energy production for the day. According to the details on timeanddate.com, the partial eclipse in our area lasted from 2:04 pm until 4:32 pm (Eastern).
Those times line up perfectly with the dip shown on our dashboard:

Unfortunately we couldn’t find our solar eclipse glasses, so we had to fall back to ye olde pinhole method.
Update (2024-04-09): Several comments on this Ars Technica article also show dips in solar energy production.
