Abstract
Renewable energy sources are steadily becoming more popular as an alternative to conventional sources. Moreover, cities increasingly rely on solar energy to reduce the negative impacts of climate change. Therefore, renewable energy projects are conducted worldwide but face many challenges and barriers, leading to failures. Thus, this thesis had 2 main objectives: to determine the factors affecting renewable energy in Egyptian industry and to focus on solar energy and its significance. It is also interesting to compare the factors that affect and are affected by the renewable energy sector in Egypt and other countries. According to the results, the most important factors are: Studying the positive or negative impact of the population on the air and water, the positive effective of solar systems on the environment, and the Execution laborers’ skills. These findings contribute to understanding the critical factors for renewable energy projects in Egypt and are useful references for countries planning to promote renewable energy projects in Egypt. The second was that choosing the best design alternative could save a lot of time and money. Various structural systems have been used to construct solar energy systems over the past few decades. The solar energy system has a different purpose, and there is a strategic trend and a plan whereby a significant portion of government and private resources are allocated to renewable energy projects in particular due to its different uses. Construction cost, installation cost, manufacturing or import cost, project schedule, and construction method are crucial factors in the design phase of a project. analysis determines the optimal design based on a balance between cost, performance, and reliability. This thesis identifies basic factors and information for decision-makers, solar energy specialists, and structural engineers. In this study, a Decision Support System (DSS) is integrated to support the decision process of selecting the optimal alternatives of a set of steel structure solar energy systems that consider the contracted power, cover the required area based on the function of the area, and produce exactly the required amount of energy. Also, this study developing a web application for a DSS for ground-mounted solar systems. Moreover, prescribers can choose the optimal structure for solar panels based on customer satisfaction, needs, and the solar panel system’s intended function and conduct analytical investigations to facilitate decision-making in solar structural systems. The conclusions presented in this research are based on a comprehensive body of work supported by a review of scientific literature, quantitative analysis for choosing the optimal structural system for solar energy using web application based of different alternatives for structural systems, and qualitative analysis of expert opinions to identify the most important factors affecting the field of renewable energy, especially solar energy. Based on the results, the application is imperative for helping the user choose the best alternative and demonstrating the importance of reducing the weight of steel structures for solar panels. The selection of the appropriate structural system must consider the necessary energy generation, as well as whether there is surplus energy produced by the structural structures within the available area, and considering the required energy production. These are discussed in detail in case studies.
