Optimization of A Directly Coupled PV Water Pump for Irrigation Purposes: Bangladesh Perspective

In an Agricultural country like Bangladesh, agriculture plays a vital role in their economic growth. However, during dry seasons it is very challenging for the farmers to collect an adequate amount of water for irrigation purposes. Using a Photovoltaic system (PV) for a water pumping system is one of the most straightforward systems. The primary purpose of using this system is, it is environment friendly and cost-effective. In addition, it can be used without batteries or generators during the daytime. This study examines the improved and financially savvy plan for a solar- powered pumping framework to give adequate water for irrigation. February to April and also September to November are the planting seasons in Bangladesh. Due to deficient rainfall, the months of November and February are the most critical. The location that we considered for this study the amount required is around 220 thousand liters. This project intends to gather the necessary quantity of water for irrigation, mostly during the two crop seasons stated. In this case, an optimal tilt angle (=38.71°, south facing) is determined for the smallest needed panel size, which can provide the appropriate volume of water during the cultivation time for the irrigation system. Contribution-The main contribution of this work is to design a directly coupled PV pumping system for irrigation purposes with an optimized tilt angle considering the climate of Bangladesh.
