Will a PowerWall allow fast charging?
Is fast charging desirable or destructive?
How many PowerWalls are needed to fully charge your 'average' Tesla?
Irrespective, solar us a logical step with an electric car. BUT in one of the possible futures we won't have a car, garage or driveway. Indeed there won't be cars parking out the roads as the cars will be stationed/charged somewhere else and summoned on demand. In that possible future, the PowerWall would still be available for the house and grid so that future works.
Ok, I should order my solar/ PowerWall now then.
