ANÁLISE DA VIABILIDADE ECONÔMICO-FINANCEIRA DE SISTEMAS FOTOVOLTAICOS

Abstract

The growing demand for renewable energy sources, along with advancements in photovoltaic systems and rising energy costs, underscores the need to assess the economic viability of different solar system configurations. The aim of this study is to conduct an economic analysis and comparison of three types of photovoltaic systems, including On-grid, Off-grid, and hybrid. For this purpose, financial analysis metrics such as Payback and Net Present Value (NPV) were used, evaluating initial investment, operating and maintenance costs, and the time required for investment return. The results indicated that the On-grid system showed positive Payback and NPV, proving viable in areas with available electrical infrastructure. Conversely, the Off-grid system did not present positive Payback or NPV, proving disadvantageous for most applications. The hybrid system, however, achieved positive Payback and NPV, making it suitable for consumption profiles with significant demand variations. It concludes that the choice between systems depends on contextual variables and energy consumption profiles.
