Lots of good answers here. I’ll add another: setting up truly giant solar farms does not present much benefit over many smaller ones, and has significant downsides.
One of the beautiful things about solar is that you don’t need giant scale projects to break even. Solar is very modular, and after a certain size the costs scale fairly linearly. It is easier to finance/plan/approve smaller projects, and the costs are similar per megawatt as absolutely massive projects.
