Photovoltaic-green roofs: An experimental evaluation of system performance

The research focused on the experimental evaluation of Photovoltaic (PV) – green roofs under Mediterranean climate summer conditions. Two autochthonous plants, Gazania rigens and Sedum clavatum, were selected for the PV-green systems while a PV-gravel configuration was used as the reference roof. Th...
