The solar submersible irrigation system is a good solution for Benin food problems. The solar submersible irrigation system consists of a DC submersible pump, a solar controller, and a solar photovoltaic panel. The solar submersible irrigation system is a green energy system that uses renewable energy solar-powered water pumps to pump water from deep wells for irrigation and drinking water. In Africa, solar energy resources are very rich and suitable for the promotion of solar energy systems. The system has the advantages of low operating cost, simple maintenance, energy-saving and environmental protection, and no pollution.
