Study on the development, implementation and validation of a design model simulated for photovoltaic water pumping systems (PVPS)

Abstract

In this thesis work a C++ (Programming language) Codelite, V9.0.1 Software was used to design a stand-alone Photo Voltaic Pumping System (PVPS). An algorithm was developed, which would design a stand-alone Photo Voltaic system for pumping underground water. The algorithm calculates the amount of energy required to draw the water for the specified height to give pump rating and the flow rate. The inputs required are amount of water required per day, number of autonomy days, the total dynamic height and the pump efficiency. To design the solar array the inverter voltage, single panel voltage and current (dependent on the individual panel power) is used to design the series and parallel array. The developed sizing method has been validated by applying it to one real scenario case where PVPS was already present. The obtained results was (1000 cubic meter water in 7.7 hours was pumped using 10 HP pump with 21 solar panel in series and 3 parallel arrays) have been compared with the characteristics of the real PVPS. The reliability of the design procedure has been verified, observing the similarity between the calculated out puts and the respective real values.
