there's another issue: The grid was designed for voltage and power schedules of traditional fossil fueled generators, and solar acts differently.
As a result, when penetration of PV power gets too high in certain locations, expensive upgrades may be needed. An analysis reported by Greentech Media says Vermont and Massachudetts are going to be among the states where that happens as early as 2017.
Traditional electromechanical equipment like voltage regulators, load tap changers and capacitor banks aren't designed to switch on and off or up and down as often as these solar PV inundated circuits will require, and can wear out much faster as a result, making them several times more expensive as long term solutions to this challenge.

this from being a problem. This is part of the reason that utilities sometimes push back against solar, along with the dislike of change that is the default reaction of most large institutions.
