VIABILIDADE TÉCNICA E ECONÔMICA DE TELHAS FOTOVOLTAICAS APLICADAS A UMA RESIDÊNCIA UNIFAMILIAR EM BELO HORIZONTE-MG

Abstract

One of the biggest challenges in today's society is maintaining the pace of economic growth without damaging the environment and inhabitants living conditions. In this scenario, considering the renewable energy sources relevance and its importance on energy sector, we highlight the electricity generation through photovoltaic systems. Among the most recent technologies that use the photovoltaic effect, photovoltaic tiles can be evident. A technical and economic feasibility study of its application was carried out in a singlefamily residence located in Belo Horizonte (MG, Brazil), in comparison to photovoltaic panel technology, considering both system connected to the local grid. The results pointed out that both systems present technical feasibility to be applied in this case study, since the technologies were able to meet 100% of its energy needs. However, only photovoltaic panels were viable when evaluated under an economic bias. This may be due to the high photovoltaic tiles cost and also the lack of subsidies and government programs to encourage solar technologies adoption and, consequently, reduce initial investment costs as well as increase the positive cash flow balance. This work presents a contribution to foster photovoltaic tiles technology, as a sustainable option to generated green energy and also reduce greenhouse gas emissions through as well as contribute to Brazilian energy matrix diversification.
