An experimental research is carried out on a 500 watts Solar Photovoltaic Powered Irrigation System (SPPIS) powered by two 250 watts PV panels to measure the performance of solar irrigation system. This performance measurement of SPPIS is analyzed as a function of weather, time, day and orientation at Wright State University, Dayton OH. The system is comprised of three basic blocks i.e. power production system, irrigation system and diagnostic or Data Acquisition (DAQ) system. The power production system includes solar photovoltaic panels, solar translator and electronics. The irrigation system consists of 100 watts DC pump and irrigation tubing etc. The diagnostic part contains the sensors to collect real time data as temperature, pressure, voltage, current, flow rate, solar insolation and water level.
The goal of this project is to examine the behavior of system and resulting effects caused by associated parameters such as temperature, solar insolation, and characteristics of voltage and current, etc. on overall performance of system. The diagnostics or DAQ of the system is structured in such a way that every single component’s behavior can be evaluated and its corresponding effects on irrigation system. The acquired data will be studied to assess the conditions under which the SPPIS performs at its best. The important part of this research is to identify the factors that regulate the current-voltage curve characteristics. Based on the acquired data of optimum performance of the system results such tilt angle, temperature effect on power output, and characteristics of voltage and current, the functions of electronics as Maximum Power Point Tracking (MPPT) and the battery performance under various load or weather conditions could be assessed.
