    Wouldn’t that be a less sustainable use of land?

    I guess maybe not if we are talking tall building, where the roof surface area may not be sufficient for the entire building. But it would be a waste not to make use of all the unused rooftops

      Yeah, in some countries, land is at a premium. No way would it be wasted on just solar panels. Rooftop installations make the most sense.

      They are even testing putting them afloat on dam reservoirs.
