This can power 140k homes and takes up 5 square miles. So, just to power San Diego city alone, you’d need 50 square miles. This project costs $2.2B and it costs 2.6x to generate power as a coal power plant. I’m not sure you’d have enough dessert land to produce power for everyone. Then there are the birds that will die and the animals that have their habitat wiped out. Yeah, this sounds very feasible.
