Análise de viabilidade econômica de um potencial modelo de negócio baseado na geração de energia solar fotovoltaica

Abstract

With growing environmental concerns related to the use of fossil fuels, the need arises to promote solutions that explore the energy potential of renewable. In this context, photovoltaic systems are becoming an increasingly popular option. more viable for clean energy generation in Brazil, due to abundant solar resources from the country. This study analyzes the use of photovoltaic solar energy in generation systems distributed to offset energy credits, focusing on the residential sector. before the exposed, the present study aims to analyze the economic and financial viability of a photovoltaic project focused on the sale of photovoltaic models for complexes housing. The project aims to offer solar energy generation solutions through the sale of photovoltaic systems, providing the opportunity to become self-sufficient in energetic terms. The research is justified by the importance of exploring the potential of business of companies that operate in the sale of residential photovoltaic systems, aiming at energy savings for residents and reduced electricity costs. The analysis of economic viability of this business model will provide valuable insights into the sustainability and the potential financial return that this sector can offer. A technical viability of the systems and their economic potential are evaluated through the net present value (NPV), internal rate of return (IRR) and time of return on investment (payback). A system with an installed capacity of 46.2 kW is proposed, scaled and simulated with the System Advisor Model tool. The study was carried out in ten Brazilian cities, which were selected taking into account the strong potential for the generation of electricity through photovoltaic systems in different regions of the national territory, also considering the existence of a significant number condominiums and residential buildings. From a technical point of view, even if some cities have not met their demand target, it is still possible to reap the benefits of deployment of photovoltaic systems, reducing energy costs and reducing the reliance on conventional energy sources. When analyzing the economy, ten projects had different NPV and IRR. However, considering these indicators, all proved to be profitable, and the IRR exceeded the minimum value of the Minimum Attraction Index (MAI). Per Finally, the impact of changes in the price of energy in kWh and taxes was observed. related in different regions. Where the higher the energy value, the shorter the period. of return and the higher the NPV and the IRR of the projects.
