Experimental energy analysis of a stand-alone photovoltaic-based water pumping installation

摘要

Maturity of the photovoltaic (PV) technology is emphasized by the numerous types of applications encountered nowadays. One of the most interesting applications, however, is the use of PV units for pumping water, i.e. the implementation of PV pumping systems (PVPSs) in order to cover both irrigation and potable water needs, especially in remote areas where connection to the local grid is not always feasible. To further establish the utilization of such systems, the performance of a typical PVPS is currently examined. For this purpose, both the efficiency of the system and the ability to transfer water are determined. Detailed measurements provided by a series of experiments are used, while for increased reliability of the results presented, an error analysis is accordingly carried out. Finally, from the results obtained, one may argue that a similar PVPS not only comprises an environmentally friendly solution but also contributes substantially to the satisfaction of remote communities' water consumption needs.
