This study aimed to evaluate the design of a grid-connected photovoltaic (PV) system according to the positioning of the modules which compose the generator depending on tilt and azimuth angles in Goiânia, Goiás. In that purpose, a review of the literature was carried out concerning the main methods of inverter sizing ratio analysis applied to grid-connected PV systems. Starting from an hourly average climate measurement database from Goiania, an algorithm was developed to search for the ideal local inverter sizing ratio, considering the use of polycrystalline module technology. The parameters used in the analysis were provided by the manufacturers of the componentes used in the grid-connected PV system in installation at the Electrical, Mechanical and Computational Engineering School (EMC) from Federal University of Goias (UFG), which nominal power is 33.84 kWp. An inverter sizing ratio band of 0.54 to 0.77 was obtained for a -90° to +90° azimuth angle variation and 0° to 90° tilt angle variation. The potential of financial indicators improvement was verified and it was estimated a potential reduction in the levelized cost of energy above 10% comparing the inverter sizing ratio improved system to an unitary inverter sizing ratio system.
