Financial Impact of the Binomial Tariff in the Investment in Residential Photovoltaic Systems

The development of financial analysis methodologies for the investment return in photovoltaic distributed generation in Brazil is of interest to residential electricity consumers. In this sense, the objective of this study is to evaluate the financial impact of binomial tariff application on investment return in photovoltaic distributed generation for residential consumers, considering the changes proposed in Brazilian electric sector regulation. The paper consists in the comparison of economic indexes using the current residential tariff and tariff models proposed by the electric sector regulatory agency in recent public consultations. The methodology is based on definition of the energy generated by the photovoltaic systems, financial parameters, technical parameters and obtaining economic indexes. The investment attractiveness in photovoltaic solar generation is first calculated with the current tariff model, the second case is based on the Public Consultation nº. 33 of 2017 and the third case is developed considering the Public Consultation nº. 10 of 2018. The methodology proposed and results obtained aim to contribute to the development of a fair legislation for investors and agents in electric sector.
