Yes and No.
It still applies in that grid storage of renewables via EVs is probably gonna be a big thing. What's different is that you personally might not benefit from it so much. Obviously if your car ain't at home you ain't charging it from your own panels. You'd get less of a benefit 'cause in the day your panels would be going into the grind instead, at whatever feed in rate you can get.
However, as Harry alluded to, there's every chance that the power companies will want to incentivise taking power off you at peak times. I.e. they'll reduce your rate, or maybe even pay you (hah!) to use power at certain times, which will be much more possible if you've got a big battery available.
Put it this way. IMO grid storage is The Next Big Thing™ in power distribution, at least in western Europe. If you've got a bunch of people (i.e. me and you) willing to buy big expensive batteries and plug them into the grid (we have EVs) someone is gonna find a way to take advantage of that.
