The problem with rooftop solar is that it is very, very, expensive compared to utility grade solar:
>…Rooftop solar photovoltaic installations on residential buildings and nuclear power have the highest unsubsidized levelized costs of energy generation in the United States. If not for federal and state subsidies, rooftop solar PV would come with a price tag between 117 and 282 U.S. dollars per megawatt hour.
If we want to subsidize a renewable energy source, why should we subsidize rooftop solar when we could subsidize utility grade solar or wind? Money is fungible and not unlimited - a dollar that goes to subsidize residential rooftop solar is a dollar that would go much, much further if it was used to subsidize utility grade solar or wind.
Rooftop solar subsidies are also unusual in that much of the subsidy is often paid by less well-off households to subsidize their wealthier neighbors - sort of a reverse Robinhood scheme.
