What they do not model is the local effect of the cities that will need to be built to service all these panels. 9,000,000 square KM is a gigantic area. Millions of people will be needed to maintain these farms. Those people will need to either live locally or be transported regularly. The study should model how the presence of those people in such a relatively underpopulated area will impact local climate.
1 person per km2 = 9million people. But I'd bet you would need a couple dozen people for every km2 of solar farm, and associate infrastructure, meaning perhaps 100 millions people. And then all the people to provide services to those people ... this is like building a few new countries from scratch.
