“…Currently all countries are seeking for alternate sources of energy, among of them, the solar energy is the most numerously exist form of renewable energy [1], [2]. Compared with other systems reliant upon renewable energy whether it is wind, geothermal, or biomass energy, photovoltaic systems are becoming more widespread [3], [4]. Solar PV power is represented to be a common renewable energy source in the industrial and residential sectors.…”

Solar energy is a prompt creating source of energy worldwide. Airports are typically large, shade-free structures and have great areas, which offer the idealistic platform for installing large surfaces of photovoltaic panels generating more than 20 GW/yr. Optimization of the photovoltaic system is a main factor to promote the power conversion efficiency. Solar-radiation amount depends on an essential factor, which is the orientation of the photovoltaic modules. The azimuth and tilt angles for the photovoltaic panels are important factors that impact the receiving of the solar radiation, accordingly have a major influence on the photovoltaic system performance. PVsyst software is an important simulation software for the design of the photovoltaic system. Also, PVsyst enables the calculation of the amount of energy generated. This study provides a proposal for installing a photovoltaic plant in Cairo International Airport. Moreover, the study gives several orientation cases to get the optimal yearly tilt and azimuth angles. The optimal tilt and azimuth angles should be obtained to enhance the annual energy yield. The study also improves the energy generation by carrying out optimization to obtain the dualseasonal optimal tilt angles for summer and winter. The simulation for the energy generation and the orientation-optimization analysis was done by the PVsyst software. The optimization results indicated that the optimal azimuth angle is 0°, the optimal yearly tilt angle is 30°, and the generated energy is around 35 GWh/yr. The optimal dual-seasonal tilt angles are 10° in summer and 50° in winter that maximized the generated energy to be about 36.5 GWh/yr. This optimization study contributes effectively to increase the energy production by installing a photovoltaic plant and using an optimal photovoltaic panel-orientation, as well as being able to save about 50% of Cairo-International-Airport Terminal-Building 3 yearly electrical consumption.

“…The generation efficiency is mainly influenced by the amount of solar radiation incidence on PV panels. Solar-radiation magnitude depends on two important factors, azimuth and tilt angles of panels [16], [17], [3], [18]. Figure 3 illustrates azimuth and tilt angles [19].…”

“…where m is the weight of the solar modules; e is the eccentricity, which is the distance from the center of the modules to the center of rotation of the system in a direction perpendicular to the modules, and α is the angle between the solar modules and the vertical axis. The aerodynamic torque from ambient wind corresponding to the axis of the rotation system [27] can be given by:…”

“…where C M is a coefficient that depends on the angle between the wind direction and the solar modules; v wind (m/s) is the wind speed; A(m 2 ) is the surface area of the solar modules, and a (m) is the width of each solar modules. Typically, during the calculation of the aerodynamic torque, its maximum value is chosen as C M = 0.6 [27]. We assume that the tracking system is activated when the wind is at level 6 (associated with a maximum speed of 13.8 m/s).…”

“…The performance of the PV system equipped with a single-axis sun tracking system in Saudi Arabia generates 28-32% more energy as compared to that of a fixed PV system [26]. The improvements effected by sun trackers is approximately 15.13% in Taiwan (single-axis) [27], 20-50% in Europe (single-axis) [28], 30.79% in Turkey (dual-axis) [29], 5.76% in Tunisia (dual-axis and single-axis) [30], and 12-25% in United States of America (single-axis) [31]. Although the sun tracking system could improve the energies gain by the PV modules in many cases, some studies suggest that it is not applicable in hot regions [32].…”

Recently, the demand for small grid-connected photovoltaic (PV) systems has been rapidly increasing; this is due to the reduction in the costs of grid-connected storage systems as compared to those of the stand-alone ones. Notably, the performance of the solar tracking system is not only depending on the types but also the region that they are set up and used. To understand how solar tracking systems work globally, we need to know their performance in each country and even the different parts of a country. In this study, two grid-connected PV systems with 250 W solar modules were used to investigate the efficient improvement of a single-axis sun tracking system in Central Vietnam. First, a mechanical tracking device with a linear actuator and a controller was designed and then its performance was comprehensively investigated with a grid-connected PV system. In addition to evaluating the energy gain by the tracking system, this study also considered the energy consumption of the linear actuator with its controller and a small grid-connected PV system; this has generally been omitted in previous works. Experimental results indicate that the total energy consumption of the tracking system was approximately 2–8% of the energy generated by the grid-connected PV system. The maximum overall energy generation was confirmed to have increased by up to 30.3% on a sunny day upon using the proposed tracking system; further, the net energy gain by using the sun tracker was ascertained to be 15.2% in average weather conditions. Based on the success of this work, we will keep experimenting with other parts of Vietnam. Also, we will collaborate with colleagues in other countries to create a guideline for understanding and using the solar tracker regionally and globally.
