Increasing the total productivity of a land by combining mobile photovoltaic panels and food crops

摘要: Abstract Agrivoltaic systems, consisting of the combination photovoltaic panels (PVPs) with crops on same land, recently emerged as an opportunity to resolve competition for land use between food and energy production. Such systems have proved efficient when using stationary PVPs at half their usual density. Dynamic agrivoltaic improved concept by orientable derived from solar trackers. They offer possibility intercept variable part radiation, well new means increase productivity. The matter was analysed in this work comparing fixed dynamic two different orientation policies. Performances resulting were studied varieties lettuce over three seasons. Solar tracking placed all plants a microclimate where light shade bands alternated several times day any plant position, while split surface into more stable shaded sunlit areas. In spite these differences, transient shading conditions increased leaf area compared full-sun conditions, higher conversion transmitted radiation crop. This benefit lower during seasons high under controlled As expected, regular largely electric production but also slightly hence crop biomass. A large achieved restricting around midday, which resulted biomass spring counterbalanced efficiency summer. result, productivity per unit reached trackers instead maintaining close or even similar that obtained conditions.
