Electric energy is essential for the development of a State. Renewable sources represented 83.75% of the Brazilian electricity matrix in 2020, however only 1.73% originated from solar energy, even though the solar irradiation rates in Brazil are above the global average. In recent years, the national electricity tariff constantly increased above inflation, so that the investment in photovoltaic solar energy became an advantageous alternative to minimize the effects of this tariff increase. Every financial operation aims at future receipts to liquidate the initial investment; thus, this study analyzed the economic feasibility of a parking lot with photovoltaic modules in the courtyard of the Infrastructure and Public Services Department of the municipality of Mundo Novo – MS. After obtaining data about the average electric consumption and the incident radiation in the locality, it was possible to dimension the photovoltaic parking lot to supply the energetic needs, besides injecting the surplus into the network and providing shading for four passenger vehicles. The efficiency losses of the photovoltaic system due to temperature, tolerance, electrical incompatibility, time of use and shading were investigated. After budgeting foundations and preliminary services using the SINAPI table, besides the carport and the photovoltaic system components through direct contact with suppliers, the final price was obtained, enabling the analysis of feasibility through financial indicators. Thus, installing a system with maximum power of 13.35 kWp on the cited locality would result in an annual rate of return of 35.29%, higher than the SELIC rate, established as the minimum attractiveness rate. Therefore, considering the value of money during time, the initial investment will be returned in 4 years and 2 months. |
