Which is why I asked about Manhattan. How do you scale up from six panels on one hippy-dippy house to x panels in a city of ten million?
Assuming the hippy-dippy house is a family of 4, (6/4)x10,000,000 = 15 million panels. Now cheaper per panel because of the economy of size.
How many automobiles (much harder to make per unit than a solar panel) are there in Manhattan? One source I got was "According to the data, only 1.4 million households in the City out of the total 3.0 million owned a car." So now we need to show that owning some 11 panels each is more expensive than buying a car, over the service lifetime of these items. ??? What is the problem?
The buildings need only do themselves, not other buildings. How many solar windows per typical building? What is the power consumption of a typical building? Do it building by building. Make it optional.
And how big would the battery be to prepare for a rainy day?
each panel array would have it's own battery/capacitor storage. It would foolish to put it all in one place (like for example, Battery Park - a target of rising sea levels). Have each building's 13th floor decked out with Elon Musk's wall units.
