This paper aims to analyze the harmonics generated in a system when there are different levels of penetration of solar photovoltaic generation. A real system in the city of Buzios (Brazil) was simulated in the program HarmZs with measured values of existent panels. The harmonic total distortion of voltage was evaluated and it was seen that in the scenarios with massive penetration of photovoltaic generators, the limits established were violated, indicating that it will be necessary to make new arrangements in the system, such as in filter allocation, to support the entrance of a great amount of distributed generation. This study shows that the insertion of new (small) renewable sources connected to the grid should be discussed within the context of power quality to prevent major distortions in electrical systems that are adequate and meet the existing regulations for power distribution.
