We need both. Utility scale solar has it's own set of problems related to land use. There is nothing about rooftop solar that makes it make less sense than utility scale if it's done well. There is a promising future ahead of us where building regulations will take into account cosine losses and start mandating equatorial facing rooftops, solar trackers, etc. It just seems weird now because we haven't seen it done yet with any kind of aesthetic vigor.

By the way, it's not commonly acknowledged but in my experience solar panels are very underrated as effective insulators, reducing A/C costs.
