Yes, it's cheaper for utility scale solar because the environmental cost of dedicating land to an industrial purpose is ignored. In the case of solar it is still preferable to do fields of solar to replace carbon-emitting power generation though. But I do think governments should subsidize rooftop solar to within shouting distance of "utility" solar. Heck I think they should be subsidizing solar and storage regardless of location. Once tech curves make existing utility installations obsolete in a few decades, then maybe move them back to rooftop.
