The objective of this work is to study and evaluate the impacts and challenges of the insertion of distributed generation (DG) linked to photovoltaic (PV) technology in Brazil and to verify its impact in a residence energy bill. The Brazilian panorama of the generation PV, the obstacles for its implantation, as well as its technical and regulatory solutions are analyzed. Since 2012 there was an increase in the installation of DG due to regulatory changes. The exemption from taxes such as PIS/COFINS and ICMS caused a growth of 233% in PV installations between 2015- 2016. In relation to tariff changes, the appearance of the white tariff in 2018 may negatively influence the growth of PV photovoltaic, because, for those who adopt the tariff, it would reduce the off-peak energy offset credit, being in this period of the day the biggest PV generation. Thus, it will reduce the savings of its monthly bill in relation to the conventional tariff. The white tariff comes as a financial stimulus to the consumers change their load curve, shifting their maximum demand out of the peak hours, however it reduces the economy generated by the DG PV, because the reduction of the residential energy bill with the installation of DG PV is 90% in relation to the conventional tariff, however, the reduction of the energy bill with the change of habits added to DG FV and with the white tariff is 78%. Thus, the implementation of DG PV is directly linked to its cost and the consumer who choose to install DG PV should remain with the conventional tariff.
