The present study evaluated a photovoltaic system with a tracker of two daily positions located at the State University of Ceará (UECE), Fortaleza, Ceará. A 50 Wp rated power system with a two-position manual tracker daily was compared with a fixed system at 0º in the horizontal plane. The results of the three stages of the experiment were collected in 16 days, in July/2021 and August/2021. Several data were collected, such as solar irradiation, electricity generated, and battery charge status. Other data were calculated from the data collected, such as reference productivity, the productivity of photovoltaic arrangement, the efficiency of photovoltaic arrangement, performance ratio (PR), and capacity factor (CF). The system with the two-position daily tracker generated 23.86% more electricity than the fixed system. In an additional comparison, a system with a manual tracker of 3 daily positions generated 29.89% more electrical energy than the fixed system. Finally, a simulation was performed in the Radiasol 2 program, seeking to perform a comparison similar to the practical experiment.
