Sistemas fotovoltaicos : sua aplicação viabilidade económica

Abstract

A procura e desenvolvimento de soluções energéticas alternativas de produção de energia eléctrica, viáveis e sustentáveis, assumem vital importância na agenda actual das nações desenvolvidas. Considera-se que uma solução energética alternativa é viável e sustentável quando permite suprir as necessidades de consumo energético mundial, sem danificar o meio ambiente, e com custos razoáveis. De todas as soluções energéticas renováveis e alternativas de microgeração de energia eléctrica, as energias fotovoltaica e eólica ocupam lugar de destaque; pois, quando associadas entre si, formam os sistemas energéticos renováveis e alternativos mais completos e competitivos. Nesta dissertação, realizaram-se estudos de viabilidade económica – na perspectiva/vertente microeconómica, privada e individual – e técnica das aplicações de sistemas fotovoltaicos em Angola, mais propriamente nas regiões das províncias de Luanda e Huambo, a partir de simulações feitas segundo estudos teóricos de aplicações destes sistemas em Portugal, na região de Famalicão. Recorreu-se a esta alternativa em virtude de não ter sido possível efectuar directamente os estudos em Angola, como inicialmente estava previsto, por razões alheias à Universidade, aos orientadores e ao orientando. A dissertação foi estruturada em duas partes: uma primeira parte teórica, em que se descreveu extensivamente os componentes mais importantes que integram os sistemas fotovoltaicos e eólicos; e outra parte teórico-prática, contendo os estudos de caso. Com base nos resultados obtidos nos estudos de caso, foi possível concluir que os investimentos num sistema fotovoltaico dependente, para regime bonificado – com base nos regulamentos do DL nº 363/2007, de 2 de Novembro – e em sistemas fotovoltaicos independentes, para redes eléctricas domésticas situadas a menos de meio quilómetro da extensão da rede eléctrica pública de Famalicão, não são economicamente viáveis. Foi ainda possível concluir que os sistemas fotovoltaicos – nas províncias do Huambo e Luanda – apenas são viáveis para instalações eléctricas domésticas independentes.

The research and development of alternative energy solutions for electricity production, viable and sustainable, are vital in the current agenda of developed nations. It is considered that an alternative energy solution is viable and sustainable when it meets the needs of world energy consumption without harming the environment, and with reasonable costs. Among all solutions of renewable and alternative electricity microgeneration, solar and wind energy have a prominent place, because, when combined together, form the alternative renewable energy systems more comprehensive and competitive. In this thesis, have been conducted studies of the economic – in the microeconomic, private and individual view – and technical viability of the applications of photovoltaic systems in Angola – more specifically in the regions of Luanda and Huambo – from theoretical and practical simulations of the applications of these same systems in Portugal, in the city of Famalicão. Such alternative has been considered because it was not possible to directly perform the studies in Angola – as originally planned – for reasons beyond the control of the University, the guiding and tutors. The thesis is structured in two parts: one theoretical, which extensively describes the major components that integrate photovoltaic and wind systems; and other theoreticalpractical, containing the case studies. Based on the results obtained in the case studies, it has been concluded that the investment in a photovoltaic dependent system, for subsidized regime – based on regulations of DL nº 363/2007, of November the 2nd– and in independent photovoltaic systems, for electrical household situated less than half a kilometer of the public grid in Famalicão, are not economically viable. It was also possible to conclude that the photovoltaic systems – in the provinces of Huambo and Luanda – are only viable for offgrid electrical installations.
