Design and analysis of solar water pumping for drip irrigation in Iran

In this thesis, a solar water pumping system is designed and studied for drip irrigation of a 14.7 hectare grape garden in Iran. Firstly, two kinds of solar-powered water pump systems 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. Secondly, a cost-effective IoT-based SCADA system for a solar water pumping system was developed. The IoT-based SCADA is comprised of a raspberry pi zero W, Arduino nano, camera, SIM 5320A 3G module, voltage, current, and light sensors. We used Node-RED to design a graphical user interface and published it securely to the worldwide internet. This allows a user to connect to the server via an IP address and monitor and control the system. The implementation of the project resulted in an open-source server and cost around CAD$162.38
