Ziel dieser Studie ist es, die Auswirkungen solarbetriebener Wasserpumpensysteme aus technischer und wirtschaftlicher Sicht zu bewerten, die optimale Anlagengrö e zu ermitteln und diese mit herkömmlichen Dieselpumpensystemen zu vergleichen, um den Wasserbedarf für Bewässerung und Viehzucht zu decken. Als Standort wurde ein abgelegenes landwirtschaftliches Gebiet in der Stadt Fayoum in Ägypten ausgewählt, wo für eine Förderleistung von 121 m3/h eine maximale Spitzenleistung von 443 kW erforderlich ist. In dieser Studie werden drei Systeme untersucht: ein Diesel-System, ein netzunabhängiges PV-/Batterie-System und ein System zur Erweiterung des PV-Netzes (netzgebunden). Die vorgeschlagene Methodik zur Optimierungsdimensionierung wird mithilfe des Softwarepakets HOMER 3.13.8 unter Berücksichtigung der geringsten Netto-Gegenwartswertkosten und Energiekosten durchgeführt. Zudem wird die Leistung für die Pumpenanlage geschätzt. Die Ergebnisse zeigten, dass die Netto-Gegenwartswertkosten des netzgebundenen PV-Erweiterungssystems das Dreifache des netzunabhängigen PV-Batteriesystems und das Vierfache des Diesel-Systems betragen. Die Stromkosten betragen 0,07 $/kWh für das netzgekoppelte PV-Erweiterungssystem, hingegen 0,332 $/kWh für das netzunabhängige PV-Batteriesystem sowie 0,434 $/kWh für das Diesel-System. Was die CO₂-Emissionen betrifft, so ist der CO₂-Aussto des PV-Netzerweiterungssystems sechsmal geringer als der des Diesel-Systems.
