When there is only 50% totality, photovoltaic also makes 50% less. You just do not notice it when looking around, because your eyes adjust to the changed brightness. So a photovoltaic produces less for a longer time. What I found, for the 2017 eclipse, was that around 16GW were impacted with at most a reduction of 5GW in one moment.
