The nature of solar calls for a decentralized model, with each house having solar panels and a battery - just like most houses in the US have their own heating systems.
Big, entrenched utility companies don't like it because this would take much of their profits away. That said, the grid would not completely go away - it could still serve as a means to sell/buy extra energy if need be.
The problem with this is that the economics of our grid infrastructure and more importantly, the economics of existing generating capacity depends on it running most of the time. Imagine if you had to amortise all those fixed costs over the 5% of the time that you need them.
