I just put 14.4 kW of solar up, one of the largest installs in my community. I put 25 or so kWh of battery capacity, also respectable. Problem is, there are plenty of days where my system only generates 10-20 kWh of energy. Which is not even enough to run my house, much less my cars. And this is sunny California. Obviously I like the tech which is why I invested but I'm not sure it is going to help alleviate this issue completely (enough generation that's centralized).
