Intelligent Performance Optimization of Photovoltaic Stations on the Roofs of Public Buildings in Egypt

Abstract

Many public and religious buildings in Egypt, particularly public schools (31,290 public schools), have empty roofs that are not being utilized. The demand to generate electricity from photovoltaic units is to confront the severe climate changes that have been occurring over the previous ten years. This research proposes installing small-sized stations on the rooftops of public and religious buildings. The roofs of these buildings can be used to produce clean electrical energy to power those buildings as well as the government's electrical grid. This research uses a variety of artificial intelligence programs, including Google Earth, Skelion, and PVsyst software (photovoltaic systems), to deduce the following variables: site coordinates, dimensions, surrounding obstacles, daily sun angle during the year, and climatic factors for that area. The research is dependent on numerous variables, including angles and heights of the sun in that area, building dimensions, surface area available for establishing the station, and dust. The search results showed that the average production of the station installed on the roofs of school buildings ranges from 270 to 450 KW annually. Therefore, exploiting the roofs of Egyptian public schools is expected to produce renewable electrical energy ranging from 8,448 MW to 14,080 MW annually.
