摘要：The Tunisian Solar Plan, a renewable energy development plan elaborated by the government, foresees a 30% share of renewable in the electricity mix by 2030. The solar photovoltaic capacity that can be installed for pumping water for irrigation is estimated at 24 MW by 2030. The water pumping system in the agricultural sector is considered among the main processes requiring the use of photovoltaic solar energy particularly in areas without an electric grid. The Photovoltaic Water Pumping System (PVWPS) contributes, in addition to the optimization of water pumping, to improve their energy performance in order to reduce their water consumption for irrigation. In Tunisia, PVWPS was adopted by the Ministry of Agriculture as a trustworthy alternative solution to cover the potable water needs of people in faraway areas, particularly in southern Tunisia. A novel real-time monitoring system for a PVWPS is proposed in this paper. The purpose of the monitoring system is to provide a useful tool for the operation and management of the PVWPS using the MODBUS communication protocol and the SIM900 module connected to ARDUINO to extend the control of the PV inverter to a distance greater than 1800m.
