There would need to be a massive oversupply of energy to make a distributed model work since you can&#x27;t share the excess you have or get extra when you need it.<p>I don&#x27;t think people would be happy moving to a battery-only model where if their power usage spiked they were SOL until they installed more solar.<p>And that&#x27;s assuming everyone has the space to install enough solar; residential high rises certainly wouldn&#x27;t be able to power themselves unless they coated their sides with solar panels, and that may not even work in dense neighborhoods.<p>Unless the whole solar + battery kit was significantly cheaper than grid solar, not just on a per watt basis, but with all the overcapacity you need for fluctuations to not be brutal, I doubt the predominant model will be distributed.
