The property evaluated does not have electricity supplied by distribution networks, and the photovoltaic system designed is intended to exclusively supply a 1 hp submersible motor pump and a 1/2 hp centrifugal motor pump, which were selected for this study based on data collected on the property. The sizing of the water pumps and, consequently, the photovoltaic system was carried out considering the quantity of 320 açaí plants with a consumption of 100 liters of water per plant and the solar irradiation considered at the site was 4.48 KWh/m2. When sizing the generating system, it was determined that 6 photovoltaic modules from 600 W the manufacturer Era Solar were needed, connected in series, resulting in a nominal power of 3600 Wp in the system and a daily energy generation capacity of 16.11 KWh/day. To analyze the results, an initial investment of R$12,645.18 was calculated for the purchase of motor pumps, frequency inverter, photovoltaic modules, cables and installation of the photovoltaic system. And using the kilowatt hour tariff set at 0.93845 R$/KWh for rural areas in the state of Pará in 2025, with a forecast annual increase of 5.6% in the cost of energy, and an estimated annual degradation of 0.55% in the generation capacity of the modules. A table was developed in Excel software to assess the economic viability of the project over a 25-year period using financial indexes. Using two scenarios as a comparison, the first with the investment being made by the owner and the second with financing from Pronaf Bioeconomia. Therefore, in Scenario 1 for a MRA of 14.83%, the results observed were a positive NPV of R$ 10,515.56, an IRR of 24%, which is greater than the minimum attractive rate, and a payback of 5 years and 5 months. While in Scenario 2 for the same MRA of 14.83% the results observed were a positive NPV of R$ 3,004.62, an IRR of 17%, which is also higher than the minimum attractive rate, and a payback of 8 years and 11 months. As a result, it was concluded that investing in this photovoltaic project is financially viable, both with direct investment and through PRONAF financing.Acesso AbertoSistema fotovoltaicoIrrigaçãoViabilidade financeiraÍndices financeirosQuilombo de UmarizalPhotovoltaic systemIrrigationFinancial viabilityFinancial indexesCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::SISTEMAS ELETRICOS DE POTENCIA::GERACAO DA ENERGIA ELETRICATrabalho de Curso - Graduação - MonografiaAttribution-NonCommercial-NoDerivs 3.0 Brazil
