"Growing city populations and limited space are driving the adoption of green
roofs and green walls covered with living plants. As well as boosting
biodiversity, green roofs could play another unexpectedly valuable role by
increasing the electricity output of solar panels.
As solar panels heat up beyond 25℃, their efficiency decreases markedly. Green
roofs moderate rooftop temperatures. So we wanted to find out: could green
roofs help with the problem of heat reducing the output of solar panels?
Our research compared a “biosolar” green roof – one that combines a solar
system with a green roof – and a comparable conventional roof with an
equivalent solar system. We measured the impacts on biodiversity and solar
output, as well as how the plants coped with having panels installed above
them.
The green roof supported much more biodiversity, as one might expect. By
reducing average maximum temperatures by about 8℃, it increased solar
generation by as much as 107% during peak periods. And while some plant species
outperformed others, the vegetation flourished.
These results show we don’t have to choose between a green roof or a solar
roof: we can combine the two and reap double the rewards."
