Rooftop solar never really made sense in the big picture kind of way. It's about 2x the cost of non-rooftop solar, so why should we be putting it on roofs when there is still plenty of non-roof space to put it? If we get to a point where we've run out of room for solar...then sure, roofs are great (although residential roofs should probably be the last roofs after big, flat industrial/commercial roofs), but the only reason it ever made sense to begin with was extremely large subsidies that probably should have gone to other renewable efforts.
