How does solar/wind get through 2020 wildfires

A region of several states (in this case, Oregon/Washington/California/Nevada) had skies like pic related continuously for about 2 months last year. If we go to mass solar panels for the bulk of energy production, how does the grid make it through that time without completely collapsing? Just have 2 months or so of energy storage on hand for the entire grid?
