This paper, of the network parity situation of photovoltaic solar energy with conventional electrical energy sources, such as hydroelectric and thermoelectric for Peru is analyzed. For this purpose, a review of how the electrical tariff is set for the residential end-user of conventional energy sources has been made. Furthermore, it is shown what it consists about, the cost leveled of energy for the case of photovoltaic solar energy and how this has been used for the calculation of the electric rate of this type of source. A review of the auctions of photovoltaic solar plants that are installed in: Moquegua, Tacna and Arequipa is carried out. The solar photovoltaic tariff has been obtained by auctions, between the year 2010 to 2016, these have decreased significantly until reaching network parity. The costs of both energy sources are compared.
