100 km2 is about 3% of NYC's area...
I'm skeptical of your figures.
3% of my yard would be about 225 square feet. At 16 watts per square foot that's 3600 watts, which is about half the electrical capacity that my house has now - and it's an old house a big yard. Even Queens would probably produce less energy per square foot.
Do you have anything but hand-waving to show that solar will scale to NYC?

If a "solution" doesn't work, it doesn't really matter how much money it saves.
