Abstract: World population growth is leading to an increased demand for energy and food. This is creating a conflict over land use as terrain for large renewable energy facilities is not available for agricultural. As a solution, agrivoltaics combines the use of the land for agricultural and photovoltaic exploitation. In this work, the conversion of photovoltaic installations with N–S horizontal trackers into agrivoltaic installations by cultivating tree crops in hedgerows between the rows of collectors is analysed. Specifically, the shading of the crop on the photovoltaic panels is studied. It has been proved that there is an area between the collectors in which the crop would not shade the photovoltaic panels. Likewise, a new tracking/backtracking strategy is proposed to avoid shading in cases where the crop exceeds this region of no influence. Finally, it has been found that the Land Equivalent Ratio for an agrivoltaic plant in Córdoba (Spain) with N–S horizontal trackers and olive groves in hedges up to 3.0 m high and 1.5 m wide can increase between 28.9% and 47.2%. Thus, these PV installations are potentially adaptable to agrivoltaic installations making renewable energy facilities compatible with a more efficient and sustainable agricultural model.
