Study finds green roofs make solar panels more efficient
Two identical office buildings side by side in Sydney’s Barangaroo provided a perfect opportunity for solar energy researchers to test a long-held hunch. Would surrounding rooftop solar panels with green plants make them more efficient? The answer, as it turned out, was yes.
Over eight months the green roof generated an additional 9.5 MWh or $2,595 worth of renewable energy.
