Okay, but in the suburbs I see every house with hundreds of square feet of unused lawn, which is useless at best, and and ecological disaster at worst [1] [1]

  Isn’t the point of a lawn that it’s “unused” space? That’s where kids can play soccer and all that. I have 10k square feet total plot, most of it not occupied by garden, buildings and would still not prefer to have panels there rather than on the roof where the space is “free” because I can’t use it for anything else. Even at 60 degs north lots of people do have solar on the roof here (but haven’t seen any north facing)

    Oh, children actually play outside on the lawn in your area; that's wonderful. But using an inefficient roof angle isn't free. That loss of output has a cost. I would think that in some cases it is a significant cost, so I'm just surprised that ground based mounting is so rarely mentioned.
