Optimization of Solar Water Pumping Systems for Agricultural Irrigation: Comparative Analysis and Design of an Ideal Solution

This study details the optimal characteristics of these systems to design an ideal pumping solution that maximizes agricultural productivity while reducing costs and ecological footprint. The designed system is an off-grid solar pump control device equipped with an MPPT controller for 24V DC photovoltaic panels operating within a 30-48V range. This system operates directly under solar irradiation, eliminating the need for energy storage. A major innovation of this system is its ability to regulate the filling of the water tank based on the measured water flow. When sensors detect low flow, the system automatically activates the water tank recharge and stops its activity when the flow reaches a predetermined threshold, thus optimizing the efficiency of water use for irrigation. The advanced architecture of the system integrates controllers capable of compensating for solar power fluctuations and intelligent sensors to automate the pumping process according to crop water needs. This systemic approach offers a robust and sustainable method to improve water management in agricultural operations, contributing to sustainable development goals and resilience to climate change.
