The research involved modeling and simulating the photovoltaic system using PVSyst software, accounting for factors such as solar module capacity, inverter selection, and system layout. The economic analysis was conducted using financial indicators, including the Internal Rate of Return (IRR), Net Present Value (NPV), and discounted payback period, to determine the long-term profitability of the investment. The primary solution proposed was the installation of a solar carport structure, which not only generates energy but also provides covered parking, thereby enhancing campus infrastructure. Results indicated that the project is feasible, though the payback period was extended due to the additional costs of the carport infrastructure. However, this choice is justified by its dual benefits: clean energy generation and vehicle protection. Finally, the study underscores the role of renewable energy in promoting sustainability and reducing the institution’s operational costs, highlighting the relevance of energy efficiency initiatives for academic institutions. 2025-03-11T00:00:00Z https://repositorio.ifpe.edu.br/xmlui/handle/123456789/1751 Estudos elétricos no sistema de transmissão com inserção de usina fotovoltaica The increasing insertion of photovoltaic plants in the transmission system requires studies on their impacts on electrical stability. This work analyzes the influence of solar generation on transmission lines, considering voltage variations and reactive support. Through simulations in the ANAREDE software, three different scenarios of photovoltaic penetration were evaluated, to observe the behavior of transmission lines with the growth of the active and reactive power level. The study reinforces the importance of analyzing the interaction between renewable generation and the electrical system, ensuring operational safety and energy efficiency.

The proper disposal of this waste is essential to minimize environmental impacts, recover high-value materials and reduce production costs, promoting the transition to a model based on the circular economy. In this context, this article aims to present the main data and guidelines for the construction of a solid and sustainable recycling market, aligned with international best practices and the principles of the circular economy. The main technologies for recycling photovoltaic panels are analyzed, with an emphasis on mechanical, chemical and thermal processes, detailing their applications, advantages, limitations and development prospects. In addition, the paper discusses the international regulatory scenario, highlighting the gap that exists in Brazil regarding the formulation of specific public policies for the sector. In short, the transition to a fully circular economy in the photovoltaic sector requires not only technological advancement in recycling processes, but also the creation of a robust regulatory framework and coordinated engagement between government, industry, academia and society. 2025-04-02T00:00:00Z https://repositorio.ifpe.edu.br/xmlui/handle/123456789/1744 Desenvolvimento de um planejamento de manutenção de usinas solares fotovoltaicas: um estudo de caso aplicado no IFPE Pesqueira Due to the increasing number of photovoltaic systems installed in Brazil, there has been a growing need for regular inspections and maintenance to ensure that the equipment operates according to the designed conditions, minimizing risks to health, safety, and the environment. However, due to the lack of specialized training, a knowledge gap is observed in most companies regarding the efficient execution of such procedures. As a contribution to this topic, this article presents a maintenance plan that includes a set of best practice guidelines, with specific strategic questions for each relevant aspect of the photovoltaic system under analysis. The goal is to create a detective, preventive, and corrective maintenance plan that can be applied to photovoltaic systems, using recognized quality tools such as the Ishikawa diagram and the Action Plan based on the 5W2H method. The model was then tested at a ground- mounted distributed minigeneration plant with a fixed structure to define the necessary actions for equipment maintenance. The results highlight the importance of preventive and corrective maintenance, combined with continuous system monitoring, to ensure greater durability and energy efficiency of photovoltaic plants. 2024-12-20T00:00:00Z
