Abstract
In the last years, great concerns about climate change and Earth's resources shortage are being created with continuous population growth and CO² emissions. In that sense, renewables energies sources have increased the planet attention for R&D. Governments have been creating incentives and/or regulations in order to increase the shares of clean energy and develop new forms of cleaner technologies. This work studied the viability, by technological and economic analysis, of a photovoltaic generation system in a commercial company and a residential case at Rio de Janeiro. To analyzes the profitability of the project, the economic analysis is carried out by the Net Present Value and Payback period. Both scenarios indicate viability with paybacks lesser than 7 years for a system that is supposed to last 25 years. It is expected mean energy production of 315 kWh/month and 1316 kWh/month for the 2.7 kWp residential and 11.7 kWp commercial PV system, respectively. Leading to a cumulative electricity billing saving of almost R$43,000.00 (residential) and R$ 200,000.00 (commercial) over its lifetime. Since the net metering mechanism implementation in Brazil, there are great expectations in the country's photovoltaic market growth because of its great solar resource.
