Abstract(s)
Neste trabalho é efetuado o dimensionamento de sistemas fotovoltaicos para serem
instalados em edificações localizadas em Angola com o objetivo de analisar a produção de
energia elétrica através de sistemas fotovoltaicos. Utilizando o software PVsyst na versão
6.3.2 foram dimensionados três sistemas fotovoltaicos, dois sistemas destinados a ser
instalados numa residência, um ligado à rede e o outro autónomo e por fim um sistema
fotovoltaico ligado à rede para uma instalação industrial.
A determinação dos custos de investimento nos três sistemas foi obtida de forma
aproximada, tendo como base preços dos equipamentos no mercado Português e
considerando os custos de importação de mercadorias no mercado Angolano.
Para os sistemas ligados à rede é analisada a rentabilidade financeira do
investimento durante o período de vida útil dos módulos fotovoltaicos considerando três
cenários distintos. No primeiro cenário o valor da remuneração pela energia vendida pelo
produtor é igual ao valor pago pela energia comprada. No segundo e terceiros cenário de
análise económica pretende-se encontrar uma tarifa de energia que torne o investimento
rentável com um período de amortização de 7 e 12 anos respetivamente.
This work is carried out the design of photovoltaic systems for installation in buildings located in Angola in order to analyze the production of electricity through photovoltaic systems. Using PVsyst software in version 6.3.2 were scaled three photovoltaic systems, two systems to be installed in a residence, one connected to the network and the other autonomous and finally a photovoltaic system connected to the network for an industrial facility. Determination of investment costs in the three systems was obtained approximately, based on prices of the equipment in the Portuguese market and considering freight import costs in the Angolan market. For systems connected to the network is analyzed the financial return on investment during the lifetime of the PV modules considering three different scenarios. In the first scenario the amount of compensation for energy sold by the producer is equal to the amount paid for purchased power. In the second and third economic scenario analysis intended to find a power rate that makes the profitable investment with a payback period of 7 and 12 years respectively.
