Smoothing of solar output, , due to geographic dispersion of systems on days of high solar variability in spring/summer and fall/winter months: (a) normalized production of a single system (blue) and the average of 14 systems (gray) on July 26, 2016; (b) reduction in the variance of solar ramp rates, , in spring/summer as a function of the number of systems over which averaging takes place; (c) normalized production of a single system and the average of 14 systems on November 4, 2016; (d) reduction in the variance of solar ramp rates in fall/winter as a function of the number of systems averaged over.
