Irrigation is an artificial way to promote water distribution in a cultivation given area in order to compensate the plants consumption, keeping the excellent condition for cultures development, mainly, during low rainfall. To ensure a good efficiency of the irrigation system, it is necessary to understand and define factors that directly influence the crop needs, such as the evaporation, transpiration and evapotranspiration phenomena. This paper applied solar generation systems, which presents itself as a clean, renewable and economically profitable. There were presented a modern and efficient irrigation system for the maintenance of crops in São João do Paraíso - RJ. The entire photovoltaic system was dimensioned to supply the energy need, considering the climatic data of the region, geographic position and the energy consumption of the system. With an initial investment of R$ 11,641.04, the power generation system proved to be profitable, with an estimated 9 years payback. |
