The albedo (reflectivity) of typical desert landscape is going to be higher than that of solar collectors (which, by definition, are trying to collect sunlight). Large cities, which are not specifically trying to collect sunlight, already have climatic effects (because they absorb more heat). I'm not down on solar, just pointing out it has its own potential downsides which shouldn't be ignored.
