Investigating the Optimum Tilt Angle of PV Modules in Al-Sherouk City, Cairo

Abstract

Energy is a crucial element that can ensure the quality of life for citizens. The consumption of energy by citizens is increasing rapidly, and future existence also became reliant on the sufficient availability of energy and its sources. Nevertheless, energy consumption is becoming a major concern due to the increase in usage rates and the lack of sufficient renewable sources of energy. Nowadays, the technological advancement that lies in the use of Photovoltaic Panels can help in generating energy and take the advantage of the sun especially in Egypt. The usage of PV’s relies on multiple factors that can ensure the highest potential generation of energy. Therefore, several studies investigated these factors including the optimum titling angle that can be different according to the location and orientation of the panel. Modifying the titling angle can play a significant role in generating high rates of power depending on the measurements and calculations. The aim of this paper was to investigate the efficient titling angle that can be used for PV panels that are installed in Al-Sherouk City in Egypt. The methodology involved the implementation of an experimental investigation that is based on position 2 similar PV panels to estimate the power generation over a period of 2 days from 9 am to 4 pm. The findings have shown that the theoretical and experimental results were similar, and the optimum tilting angle was determined to range between 54.7 degrees and 8.16 degrees. The study demonstrated the differences between an adjusted and a fixed angle, and the variable titled angle can generate more energy than the fixed one. This paper contributes to the body of knowledge by presenting the significance of a variable tilting angle to generate more power than relying on a fixed angle as demonstrated by many previous studies.
