Évaluation de l’utilisation de l’énergie photovoltaïque directe pour le chauffage et l’éclairage des serres agricoles

Abstract

The greenhouse sector is growing at an accelerated rate to meet the increased demand for food and to sustain food self-sufficiency. Several types of greenhouses have been developed to increase production such as vertical and opaque greenhouse which ensures a period of cultivation throughout the year with a higher quantity of production thanks vertically stacked layers. Producers are turning to the use of renewable energy sources recognized for their low environmental footprint to modernize their facilities, reduce greenhouse gas emissions and reduce the costs of heating, lighting, and any other climate management device. Among these renewable energies, photovoltaic energy has gained great interest in agricultural greenhouses since it is an inexhaustible and clean source with a cheap cost of panels. In this thesis, a model which calculate the energy need for heating and lighting of a transparent and opaque greenhouse, to size the direct photovoltaic system supplying the lighting and heating system is proposed. The model is based on a set of input entered by the user which are the hourly meteorological data, the growing conditions, the properties of the greenhouse, the photovoltaic system and the lighting lamps. Simulations were launched by varying the input data to compare the energy need for heating and lighting of several types of greenhouses, geographical positions, types of crops and number of layers. Basically, the model allows to evaluate the integration of the photovoltaic system without and with the alternation of the layers by analyzing the rate of use of the photovoltaic energy produced and the percentage of the energy drawn from the network, to determine the photoperiod and the number of panels to be installed to have the least consumption or the highest rate of use of photovoltaic energy
