Modelling spatial light distribution in an agrivoltaic system for an ecological vineyard

Abstract

Traditional viticulture is one of the agriculture sectors most significantly affected by the challenges of climate change. Traditional winemaking regions, such as Spain and southern France, are struggling with scarce precipitation and extreme heat. Conversely, areas at more northern latitudes are becoming more suitable for wine production. Multiple approaches, such as the use of shading nets, are being implemented nowadays in southern European countries to adapt viticulture to climate change issues. In this context, agrivoltaics (APV) offer promising solutions by smartly providing shading to vines, protecting them from harsh conditions while promoting a correct development. This work evaluates the spatial distribution of light in an APV installation located in a vineyard in Almería (southern Spain) with the help of raytracing simulations.
