Abstract
Sustainable development and renewable energy sources are topics that have impacted the global scenario and are contributing to a greater awareness of the need to preserve the planet's natural resources and still being able to supply the energy demand. Government play a major role creating incentives and policies that provide the proper scenario to new renewable technologies rise. This paper presents a technological and financial analysis of a PV grid-connected system at residential and commercial scale located at Rio de Janeiro’s State. The model is evaluated considering technical aspects like safety, compatibility, energy production optimization and the economic tools payback and net present value. Both scenarios indicates viability with paybacks lesser than 7 years for a 25 years system. At the end of the 2.7 kWp residential and 11.7 kWp commercial PV system life cycle it is expected a mean energy production of 315 kWh/month and 1316 kWh/month leading to a cumulative electricity billing saving of almost R$100,000.00 and R$ 450,000.00, respectively. Since the net metering mechanism implementation in Brazil there is great expectations in the country’s photovoltaic market growth because of its great solar resource and PV’s potential for distributed generation.
