The non-decline in the associated costs for individual installs has to be thought about. If this is a true reflection of unavoidable costs, home installs are unlikely to break a cost barrier, and won't make substantive differences in centralized generation. If on the other hand they are mutable costs, and can be brought down, then microgrids and local power has more chance of becoming something of substance.
The bigger "win" in this is the transmission loss. Consumption close to generation has lower transmission loss so it's innately higher efficiency in that one regard.
PHES and Battery technology probably matter more now than PV as a the cost problem in generation: we need time shifting for solar power to replace other forms of generation, to get to serving demand outside of the sun.
