Estudo de implantação de sistema fotovoltaico em empreendimento comercial na cidade de Franca-SP

Abstract

The use of photovoltaic solar energy has proven to be an increasingly viable alternative both in Brazil and other locations, driven by the growing demand for energy and the high costs of electricity tariffs. Brazil, with its high solar radiation levels, offers great potential for the generation of this renewable energy, which stands out for its sustainability and low environmental impact. Photovoltaic energy has established itself as an efficient and clean solution that can be integrated into urban and rural systems, significantly reducing electricity costs. In this study, three quotes from local companies were analyzed for the implementation of a photovoltaic system, considering the energy demand identified through the analysis of electricity bills. Based on this data, the proposed values, energy generation capacity, and financial return of each proposal were evaluated to determine the most advantageous option. Technical and economic feasibility studies indicate that implementing photovoltaic systems offers attractive financial returns, with relatively short payback periods of around 3.6 years and high Internal Rates of Return (IRR). In urban areas, installing these systems in residential and commercial enterprises has proven to be an effective solution, especially in neighborhoods with high demand and good solar incidence. In rural properties, the benefits are also evident, with energy cost reductions being an additional attraction for farmers. Furthermore, the photovoltaic systems market in Brazil has been stimulated by new government incentives and regulations, facilitating the adoption of commercial enterprises and condominiums into distributed generation. Economic studies conducted in rural properties and commercial buildings confirm that investments in photovoltaic systems are financially viable, providing a good return on investment and significantly contributing to long-term energy sustainability.
