We already have vast plots of land being taken up by parking lots and buildings. There is a hospital in my area that put solar panels over the parking lot. It is really nice. Your car interior stays cooler. Many buildings have their AC cooling fans on the roof. Solar panels would also shade those and help make them more efficient. All of these areas already have a hookup to the grid. Substation may need to be modified but it isn’t as dramatic as you make it sound.
yeah but check the economics. climbing on roofs to install 3 m² of solar panels is just not worth it. the total cost of the system is not just the cost of solar panels + land area, but rather solar panels + land area + installation workers cost. and installation work costs significantly more on a roof than on a flat plain area, which is why the plain land is cheaper overall.








i think that it should be able to be sold, but not as food, i.e. only if it has special warnings on it that it’s not safe for human consumption.
