The architecture design of the city is accomplished by Sketchup software which was used to design buildings and facilities within this city integrated with Skelion solar design plugin renewable energy extension. The PVsyst Solar Energy Software is used to simulate and analyze the generated electric solar power of the world's first solar city. Matlab/Simulink simulation is used to study the efficiency of the Solar Photovoltaic (PV) system under different climates in Egypt. Also, Lumion software is used for rendering and 3D animation of the solar city in live scenarios. The main contribution of this research work is to produce electricity that exceeds the consumption of the residents of this solar city or what is called the over-unity system. Keywords— Solar energy, Solar Photovoltaic, first solar city, Renewable energy, solar on-grid system, PV efficiency I. INTRODUCTION Nowadays, the world's need for electricity generation is increasing rapidly. The main reasons for the increasing energy demand are population growth, economic growth, rapid depletion of fossils fuels based on energy reserve, as well as the raising concerns over climate change because of CO2 emission. Thus, we must search for alternative sources for electrical power generation. One of these sources is solar energy which possibly has no harm to the environment. The choice of solar energy as the best alternative for the Egyptian environment is clear because a large part of the Egyptian area is desert and the whole region of the Middle East and North Africa is highly exposed to solar energy, which is a great opportunity to create completely solar, green and environmentally friendly cities. Egypt’s demand for electricity is growing rapidly and the need to develop alternative power resources is becoming ever more urgent. It is estimated that the demand is increasing at a rate of 1,500 to 2,000 MW a year, because of the rapid urbanization and economic growth. The development of the renewable energy industry has become a priority over recent years for the Egyptian government. Egypt’s present energy strategy aims at increasing the share of renewable energy, a target expected to be met largely by scaling-up of renewable energy projects. Due to its location, topography, and climate, Egypt has an average level of solar radiation between 2,000 to 3,200 kWh per square meter a year, giving it a significant potential for utilizing this form of renewable energy. Egypt is recognized as having a vast potential for solar energy applications [1-4]. Fig. 1 shows the amount of solar radiation falling on the Arab Republic of Egypt during June, as an example of one of the months of the year. It is noted that the average amount of solar radiation is approximately about 1380 watts per square meter (W/m 2 ) [8-10]. Therefore, the idea of designing the first complete solar city in the Egyptian environment that depends on solar energy is very suitable for implementation on the ground, This proposal will be detailed and evaluated in this paper. A model of a city is designed in the new administrative capital of Egypt where photovoltaic cells cover most of the surface areas as well as the facades of buildings to provide the electrical energy needed for residents of this city. The design is built using one of the structural design programs, which is the Sketchup program. The maximum power of this station is calculated using the PVSEST program, and the produced electrical capacity exceeded 3.620 GWP [4-7]. The research in this paper relies on several academic articles that have dealt with the use of the PVsyst program in simulating the use of solar energy and photovoltaic cells for the production of electrical energy. Ahmed Alnoosani et al [1] presented a design of a 100MW Solar PV on-Grid Connected Power Plant Using (PVsyst) in Umm Al-Qura University. Sanae Dahbi et al [2] presented a design of a new clean storage device for a photovoltaic system (PV) supported by the electrical grid. The photovoltaic system supplies power to a DC load, and when the power is insufficient, the electrical grid compensates for the energy deficit. Phlip Y. Najeeb et al. [3] proposed a simulation model for the PV module applied to various Egyptian environments to characterize appropriate locations to build PV panels. Mohamed Araby et al. [4] presented a study of applying Thermo-Electric Generator (TEG) in different regions in the Egyptian environment where several advanced applications of the use of TEG were proposed and discussed. Kyrillos K. Selim et al. [5-6] proposed a technique for power extraction from acoustic energy scavenging from noise sources. Fig. 1. Solar Radiation on Egypt during the month of june
