Putting solar panels on existing structures, as is the case in this article, is much better than on undisturbed land. The upper crust in a lot of southwest desert stores a significant amount of carbon which gets released when you tear it up for a construction project. Such projects also use a lot of water, which is a scarce resource in many desert areas. Plus destroying the land harms a lot of native plants and wildlife. Putting solar panels on existing structures avoids all of those problems and produces just as much energy. There is a lot of space on existing buildings that doesn't yet have solar panels and we should be making much more of an effort to improve on that.
