Floating solar makes sense in some dams that want to reduce evaporation, as they need something floating there anyway and it's almost always freshwater.
I don't think land is more than 10% of the cost of solar in most places anyway - rooftop solar can cost $5000, and I'd expect rural areas to cost less than $500 for a paddock with the area of a house.
