For this, an overview of the literature and the Ecuadorian, American, and European regulations concerning power quality was carried out to determine the regulatory parameters and admissible limits. From the quality records, it is concluded that, in general, there are no power quality problems, except for momentary current balances. In one of the cases, violations of voltage parameters, voltage unbalance, current unbalance and flicker were found. There commended parameters to be included in the Ecuadorian quality standards are individual harmonic distortion and frequency have been registered.es-ESPhotovoltaicPower qualityGrid qualityARTÍCULO DE CONFERENCIA10.24084/repqj21.451
