I think you'd be surprised how cheap land can get outside of cities.

  But then you get increased losses when transporting the energy into the city, plus the costs for the distribution infrastructure. Rooftop solar tied to the grid can be used by your neighbours when you aren't using it, which means almost no transport loss, not even crossing a transformer.

    Sure. I was responding to a comment saying the reason rooftop solar makes sense is the sunk cost in the land overwhich the roof lives. Rooftop Solar make a lot of sense, but probably the main reason is the electricity generated does not come with the cost of having to maintain a hugely expensive grid.
