First, the quote, and my comment, are in the context of commercial solar projects, not residential. Think about a company installing solar on the roof of a factory. Second, I am sure there are many different ways to implement the nudge. Indeed, maybe instead of subsidizing solar we should rather stop subsidizing fossil. Finally, talking about residential, currently almost every house has a gas pipe connected to it forcibly. And that pipe also requires maintenance. And sometimes gas leaks and your house blows up. And I don't see how forced solar would in theory be different to the current gas situation.
