The grid will never be ready for that, but smart charging may be the solution. What do I mean by that: there is already a number of solar panel installations that are feeding the grid at daytime, sometime even more than what the grid can consume. There is no way currently to link the PV systems and the cars so that when the PV generates a lot of electricity all the cars in the area will start charging, maybe discharge at night to cover home consumption, practically using the cars as very large and intelligent batteries with the side effect of using all the excess PV energy to change cars for driving. Otherwise we will be in the situation of cars charging at night will fail the grid and PVs overproducing at day will fail the grid, while most cars are used less than a couple of hours per day on average (ignoring commercial vehicles and taxi/Uber, cars carry people from home to work and back, eventually with a round trip to shop for groceries).
