Solar Water Pumping System Using IOT Monitoring System

Abstract

The Photovoltaic (PV)-powered water pumps have received considerable attention because of major developments in the field of solar-cell materials and power electronic systems technology. The motors available for the PV water pumping applications: dc motors and ac motors. AC motors are coupled to the solar panels through inverters. In solar powered PV pumps as input solar energy is freely available so it is desired that total water to be pumped out over the day, is to be maximized. Objective of the proposed system is to maximize the speed of pump and AC motor for a particular isolation (G) and temperature (T), in order to maximize the water to be pumped out. Field current speed control method is to optimize the speed of the AC motor at any value of isolation (G) and temperature (T). The dc– dc converter can be used to keep the PV- panel output voltage constant and to help in operating the solar arrays close to the maximum-power point. The proposed system is monitoring of motor speed, voltage and current range of the circuit by using IOT system.
