Why not use the many shut down malls as a solar farm? The expense of set up would be much cheaper than on land.
3 Phase power is available on every building, and connecting multiple buildings together in a mall would be relatively inexpensive.
Batteries could be placed on ground floors to reduce roof weight.
I realize that flat roofs are not designed for foot traffic, but with proper design of the system, leaks could be prevented.
Land is expensive to purchase and incurs a lot of cost to prepare.
Rooftop solar sounds like a win-win situation to me.
Constructive comments are always welcome.
