Resumo: | In the context of energy security and climate change, the deployment of renewable energy sources is key. Access to electricity and water availability can be an obstacle to the development and improvement of the quality of life of certain regions. Therefore, photovoltaic pumping along with localized irrigation systems, brings a new scope for the generation of clean energy of low maintenance and accessible to remote places, replacing the combustion engines. On the other hand, the irrigation system allows greater productivity and development for areas with low rainfall. In this way, this work had the objective of evaluating the performance of a micro sprinkler irrigation system due to the use of an amorphous photovoltaic system without energy storage unit. The influence of the photovoltaic system of water pumping in the micro sprinkler irrigation system was evaluated by the distribution uniformity coefficients (DUC) and the Christiansen uniformity coefficient (CUC). The experiment was composed of two amorphous photovoltaic panels connected in parallel, connected directly to a submersible pump, located in a water tank, with the settling to an irrigation system composed of four micro speakers. The parameters of power generated by the system, global solar radiation, water volume, wind speed and direction, relative humidity, temperature and water metering by the collectors were measured. The experiment was conducted at the State University of the West of Paraná, UNIOESTE, Campus of Cascavel, for a total of four hours in relation to the photovoltaic part and pumping, from 10:00 am to 11:00 am, 11:05 am to 12:05 pm, 2:00 pm to 3:00 pm, and 3:05 pm to 4:05 pm and two spacing with respect to irrigation, varying the spacing between the micro sprinklers, 2.0 x 2.0 m and 2.0 x 1.6 m. Values were obtained for the average efficiency of the amorphous photovoltaic system of 4.107% and pumping of 0. 0.792%. A value of 59.66% for CUC and 58.86% for CUD was found in spacing 1, and in spacing 2 it was obtained for CUC, 68.85%, and CUD with 68.05%. Therefore, it was concluded that the best time to use the photovoltaic pumping system is from 11:05 am to 12:05 p.m., due to the higher panel efficiency of 4.57% and pumping of 1.12%, and one spacing of 2.0 x 1.6 m between microsprinklers, which obtained values greater than 68% in both coefficients of uniformity.
