Agrivoltaics is a technology that combines the production of photovoltaic energy with the underlying and surrounding agricultural production, maximizing the Land Equivalent Ratio (LER), that is the land-use efficiency. Its integration in the European landscape, with a growing scarcity of available land, is fundamental to mitigate the conflict between the agri-food sector and the energy sector. This work aims to study the convective heat transfer between the ground and the panels of an agrivoltaic system, which involves the fluid comprised between the two. In agrivoltaic systems the convective heat transfer represents a key phenomenon, as it influences the fundamental microclimatic parameters of the system: the air temperature directly affects the conversion efficiency of the photovoltaic panels, which deteriorates with the increase in the temperature of the panels, and the evapotranspiration, which is the phenomenon that regulates the exchange of water vapor between the atmosphere and the underlying plants and ground.
