Optimisation of energy and vegetable production in Lubumbashi by using agri-photovoltaics systems (Research)

In Lubumbashi, the second largest city in the Democratic Republic of Congo, Some vegetable crops are exotic and come from temperate climates. These include cucumbers and zucchinis. They produce fruits that are widely consumed and have a high nutritional value. But these fruits are relatively expensive. Their production yields are low due to Lubumbashi's dry soils and strong sunshine. This is why pump irrigation is regularly used. This irrigation system requires a permanent power supply, which increases the cost of vegetable production. In addition, Lubumbashi faces an electricity supply deficit of over 24%. In this context, the installation of photovoltaic systems above the surfaces of these market garden crops could be envisaged as a means of regulating soil humidity and temperature. These AgriPV systems could help to improve the yield of these market garden crops in Lubumbashi's climatic conditions, while also serving to supply electricity to other equipment and agricultural production units. However, there is little research on the application of agriPV systems specifically adapted to the agro-climatic conditions and farming practices prevalent in Lubumbashi. This study therefore seeks to fill this gap. The aim of this project is to analyse the potential use of agri-photovoltaic systems to help improve horticultural production in Lubumbashi's climatic conditions and the supply of electricity. To achieve this, surveys of market gardeners perception and simulations of the energy and agricultural performance of agriPV systems are planned.
