Abstract
The main objective of this work was to carry out a comparative study of the feasibility of implementing rural photovoltaic farms in relation to the production of beef cattle in different states in Brazil. The study aims to assist rural producers with the decision to occupy a rural area with a photovoltaic generation system, while it could be used for agricultural production. Since, due to its agricultural vocation and food supply needs, this area would be unavailable for production for the duration of the system's useful life. Therefore, data were collected in relation to production costs in beef cattle farming, as well as the costs for implementing photovoltaic systems. Based on these data, it was possible to calculate the profit for each of the activities, subtracting the costs associated with production from the revenue obtained through the sale of inputs. Finally, cash flows were prepared and the net present value - NPV for each activity was subsequently calculated. Photovoltaic energy generation resulted in the highest NPV in all states, with Paraná standing out with a VPL of R$4,340,184.85. Beef cattle farming proved to be a low-return activity, the State of Goiás obtained the best results for this activity with a NPV of R$ 12,469.65. However, both activities proved to be viable due to having VLP greater than zero.
