Roofs are not good places for solar panels, I’ve heard. I’m struggling to recall exactly why, but I think it’s factors like if you have sun-tracing motors, they are normally installed on a pole which is top-heavy with a motor. The pole penetrates into the ground quite a bit. And when there is a hail storm you want to be able to cover up panels which requires quick access. So in short roof installations make sun-tracing impractical especially if the roof is pitched.
The article did not give any detail on /why/ a vegetated roof is better for heating and cooling the home, but I would expect the plants to effectively add to the insolation in the winter and in the summer there would be an evaporative cooling effect on the roof.
