Solar panels generate more energy on a green roof, because the water retained by the plants cools the panels. The solar panels do their part as well, creating more opportunity for biodiversity by providing shelter and shade for little creatures. A nice example of different rooftop functions benefiting each other. And solar panels can be combined in more ways. In cites they can be made into pergolas for people, or used as shelter by all types of animals in a more rural environment. The sedum on this rooftop was placed by TOPGROEN.
