This study concludes that the maximum PV penetration will be equal to whatever the minimum load is on that specific feeder. That minimum load was assumed to be 25% of the maximum load on the feeder in [13], and if the PV penetration were 25% of the maximum load, only insignificant overvoltages occurred.
