The present investigation in this thesis aims to analyze and compare the performance of a photovoltaic-powered submersible pump under three various climatic conditions in Egypt. The pump is employed to irrigate wheat and maize crops in a one-feddan farm by adopting the actual well depth and crop water requirement in the proposed locations. Furthermore, the total power of solar modules required to operate this pump is computed to reveal the auxiliary power needed for these crops at the proposed locations during their irrigation season. Several runs were carried out by using TRNSYS simulation program on the proposed system under different weather data of three Egyptian cities to investigate the performance of the system. The selected cities were Aswan, Giza and Alexandria. At the introduced weather conditions, an economic analysis is conducted to examine the feasibility of the solar powered pump versus that operated by traditional diesel generator. The results reveal that the net generated power via the PV panels to operate a pump used to irrigate wheat crop is 325, 495 and 17 kW and for maize crop is 1786, 1767 and 266 kW in Aswan, Alexandria and Giza cities, respectively. In Alexandria, Giza, and Aswan cities, utilizing solar PV panels as a power source for the pump used to irrigate wheat crop has proven its economic feasibility as it is expected to dramatically reduce the total cost by around 49, 46, and 76%, respectively and for maize crop cost is reduced by 47, 48 and 66% in the same locations compared to diesel generators.<
