Design and Analysis of Solar Water Pumping with Storage for Irrigation in Iran

Abstract

In this project, two kinds of solar-powered water pump systems for micro-irrigation of a 14.7 -hectare grape garden located in Iran were designed and studied. The difference between the systems is the storage type. One system uses a battery bank, and the other is with a water tank storage. The first system is designed using Lorentz compass3 software and includes a 6-inch 18.5 KW submersible pump. HOMER Pro software was used to model the second system and resulted in a 6-inch 11 KW submersible pump, and 44.4kw PV modules rated capacity and 144 KWh Battery Bank size. This research indicates using a storage system allows constant water flow for irrigation in solar water pumping and comparing the results, the research shows that using a battery bank is more economical than a water tank storage system.
