Abstract: This study explored the expansion of the generation of photovoltaic solar energy in Brazil based on a technical-economic approach. Opportunities for improving Brazilian NR 687/15, which regulates distributed generation from renewable energy sources in the country, were identified. The study was based on data regarding the potential for photovoltaic power generation in a region of Brazil; the acquisition, installation, and maintenance costs of a photovoltaic power generation system during its useful life; demand; and the consumption tariffs charged by the distributor. The economic viability of a photovoltaic system connected to the grid in Brazil was analysed. The results show that investment in such is not viable based on the current technology costs, financial conditions, and tariffs charged by the energy distributor. The case study also demonstrates that Brazils net metering scheme alone does not promote distributed generation for Group A consumers.

Keywords: photovoltaic systems; minigeneration; financial viability; NR 687/2015.
