Performance evaluation of two pv water pumping systems in the state of Ceará, Brazil

Francisco Samuel Portela Vidal and Lutero Carmo de Lima

Abstract: 

The present study was developed with the purpose of evaluating the performance of two photovoltaic water pumping systems located at the State University of Ceará, Fortaleza, Brazil (latitude 3.40°S, longitude 38.33°W). One of the systems has 50 Wp of nominal power and the other 100 Wp of nominal power. The results presented were based on data collected weekly in 56 days, scattered in the months of April/2018, August/2018 and September/2018. The photovoltaic pumping system of 100 Wp had the highest daily average flow in liters, reaching a value of 3,223 liters/day, while the smaller system averaged 1,669 liters/day. The 50 Wp system had low power generation, with an average of 136.27 Wh/day, equivalent to only 39.24% of the average of the 100 Wp system. The efficiency of photovoltaic conversion was 6.18% in the 50 Wp system and 7.84% in the 100 Wp system.
