Rooftop solar is far more expensive than solar put on land. The cost of rooftop solar (particularly homeowner solar) is usually hidden by implementing a big subsidy to wealthy consumers that is paid for by less wealthy consumers - sort of a reverse robin hood scheme.
We are well past the point where anyone can argue we should subsidize rooftop solar because we need to help build a fledgling industry - yet I see solar advocates continue to advocate for this wealth transfer from the poor to the well off.

- opo 4y agoYou can see the cost differences here: https://www.lazard.com/perspective/levelized-cost-of-energy-levelized-cost-of-storage-and-levelized-cost-of-hydrogen/ https://www.lazard.com/perspective/levelized-cost-of-energy-... Rooftops are unused space, but the land use is generally a small part of the cost. Utility scale solar has real economies of scale compared to one-off small installations on someone's roof.
