Yair . . . In Australia anyway I see the possibility and advantage of solar installations on a town/village level. In theory it would be more reliable and save the cost and maintenance of thousands of miles of transmission line.
This once was the case. Many towns had their own local generation and distribution system providing a few local jobs remote from the main grid . . . it could happen again with solar.
I must say though that these last few years have seen a considerable improvement in grid reliability and, even in the stormy season our power seldom goes down . . . it is obvious though that this happy state would be in jeopardy if there was a severe downturn in world and local affairs.
Cheers.
