This study aims to verify the influence of the inclination of the panels of a photovoltaic solar system connected to a grid installed at Unioeste, campus of Cascavel, PR. The system consists of ten photovoltaic modules of 330 Wp each (two panels with five modules in series) and a 4 kW inverter. Both panels were washed, and the inclination of Panel 1 was changed to 26°, which was maintained for seven weeks and three days. After this period, the slope of Panel 1 was changed to 18° and maintained again for eight weeks. The data collected from Panel 2, which remained at its original tilt of 21°, were used as a reference. The analysis of variance test was applied (ANOVA) on the average of daily panel efficiencies. When Panel 1 was maintained at 18° and Panel 2 at 21°, there was a significant difference in the average efficiencies of the panels. However, when Panels 2 and 1 were maintained at angles 21° and 26°, respectively, there was no significant difference in their average efficiencies.
