The thesis shows the process of sizing and optimizing a solar Photovoltaics (PV) system for an off-grid resort with desalination loads in Marsa Alam, Egypt. Through load profile management, an optimal hybrid solar PV-diesel system, in the sense of maximum solar share that could be achieved without using energy storage while avoiding surpluses, is analyzed and presented. The self- consumption analysis aim was to determine the optimal PV system size in two load profile case scenarios that would give a SCR of not less than 90 percent to avoid surpluses in the hybrid system. Then an economic analysis for the optimal system sizes was conducted to measure and compare the economic benefits of implementing a hybrid solar PV-diesel system. It accounts for three different scenarios for the projection of future diesel prices in Egypt.
