Détermination des conditions expérimentales permettant de mesurer l'effet de panneaux photovoltaïques, réfléchissant la lumière, sur une culture hydroponique d'armoise en annuelle en serre

Abstract

With the advent of agrivoltaics, technologies designed to minimize light losses are becoming increasingly relevant. A new type of photovoltaic panel, equipped with a surface film, is taking its place in the field of BiPV (building façade photovoltaics). This technology could be interesting in reflecting part of the sun's light. In this context, our study highlights the optimum experimental conditions for measuring this reflection effectively in greenhouses. The photovoltaic panels's impact has been tested in an experimental set-up combining four distinct factors, studied on a hydroponic culture of Artemisia annua. These factors led to the conclusion that the incorporation of this technology, while promising, was subject to certain limitations, such as fluctuations in the quality and quantity of light inside a greenhouse. Moreover, experiments carried out during the summer months showed that additional light from panel reflection was irrelevant. This is why another protocol, this time with basil in winter, was envisaged to determine the added value of this technology in another study context.
