I suspect you'd melt your grid infrastructure. They're already crumbling. If you start adding massive generation in places it wasn't designed, especially generation which can surge and dip as quickly as the weather. The good thing about domestic solar installations is that you can pair them with small (eg 5KWh) batteries and feed back the excess to (relatively) local demand. The home then becomes a lower burden on the grid in high demand times. Everybody wins.
