I Should Have Expected This

At the 1979 total solar eclipse, I watched it from a location right next to some electric power distribution equipment.  Just as totality hit, there was an enormous flash from the equipment, as (presumably) thousands of photosensors turned on lights.  Along with what sound like irrational disaster fears in many states on the totality path, this 8/7/17 CBS Philly article has a video about how the partial eclipse is going to drop 6 megawatts from California's photovoltaic grid, requiring backup power sources to come online.
