Atualmente, está na ordem do dia a subida dos preços dos combustíveis fósseis e a
problemática do aquecimento global devido ao efeito de estufa. Por essa razão a procura de
energias ditas alternativas, em complemento aos combustíveis fósseis, afigura-se como sendo
uma atividade em crescimento e desenvolvimento.
Esta dissertação insere-se no âmbito da análise económico-financeira do Decreto-Lei
nº 118-A/2010 de 25 de Outubro e da sua comparação com o anterior, o Decreto-Lei
nº363/2007 de 2 de Novembro.
Para atingir o objetivo proposto foi desenvolvida uma aplicação em “Guide MATLAB”
que permite calcular os indicadores de avaliação económico-financeira das instalações
fotovoltaicas. Foram calculados os períodos de retorno (payback), as Taxas de Rentabilidade
Interna e os Valores Atualizados Líquidos. Foram comparados os indicadores económicofinanceiros
a fim de perceber qual o Decreto-Lei mais vantajoso.
Observou-se que apesar do Decreto-Lei atual possuir uma tarifa bonificada durante um
período mais longo, e apesar dos equipamentos terem um custo mais baixo e serem mais
eficientes, é desvantajoso em relação ao anterior.
Currently, on the agenda rising fossil fuel prices and the problem of global warming due to the greenhouse effect. For this reason the demand for alternative energy said, in addition to fossil fuels, it appears as an activity for growth and development. This work falls within the scope of the economic and financial analysis of Decree-Law nº 118-A/2010 of 25 October and its comparison with the previous Decree-Law n º 363/2007 of 2 November. To reach that goal we developed an application in "MATLAB Guide" that allows calculate the indicators of economic-financial assessment of photovoltaic installations. The return periods (payback), the Internal Rate of Return and the Net Values updated were calculated. The economic and financial indicators were compared in order to determine the Decree-Law that is more advantageous to the photovoltaic energy producer. It was observed that the current Decree Law, despite presenting a subsidized rate over a longer period and the equipment has low cost and high efficiency, is disadvantageous compared to the former.
