Design of novel IoT-based solar powered PV pumping systems for agricultural applications in diverse climatic zones of India

Abstract

Irrigation is a crucial component of the agriculture industry. The gross domestic output of India is about 15 % derived from its farmers. Crop failure is common among farmers, primarily because of inadequate irrigation techniques and irregular power and water supplies. To begin with, a survey of farmers from various parts of India was undertaken in this regard, and the results indicated that most of them lacked an effective irrigation system. An inventive solar-powered irrigation system devised and deployed to address this problem includes an automated Internet of Things (IoT) system. This IoT system, which functions based on the moisture content of the soil, plays a crucial role in ensuring that the crops receive the right amount of water at the right time. Furthermore, the PV pumping system addresses irrigation issues in various Indian climate conditions, including composite, warm and humid, cold, moderate, hot, and dry. The locations chosen for these climate conditions are Jaisalmer in Rajasthan, Bangalore in Karnataka, Itanagar in Arunachal Pradesh, Patna in Bihar, and Amaravati in Andhra Pradesh. Performance ratios range from 0.514 to 0.739, system and pump efficiencies from 61 % to 88.80 %, and 57.10 %–58.60 %, respectively.
