The combination of green roofs with photovoltaic pv panels has been proposed to provide synergistic benefits as the panel is cooled by the presence of the vegetation and thus produces more electricity while the solar panel enhances growing conditions for vegetation and increases abiotic heterogeneity resulting in higher plant diversity. The panels can create shaded areas underneath with rain run off making damper areas to the front and drier areas behind.
