Influência da Irradiação Solar na Análise de Viabilidade Econômica de Sistemas Fotovoltaicos

Abstract

Resumo A instalação de sistemas fotovoltaicos mostra-se uma alternativa promissora para a geração sustentável de energia elétrica. A realização de estudos de viabilidade de instalações fotovoltaicas é de extrema importância para se verificar a disponibilidade do recurso solar no local de instalação. Esta pesquisa tem como objetivo comparar os resultados da análise econômica de um sistema fotovoltaico com diferentes estimativas de geração de energia elétrica, utilizando diferentes bases de dados de irradiação solar. Tendo como objeto de estudo o sistema fotovoltaico do campus Floriano do IFPI, foram obtidos dados de irradiação solar a partir de diferentes bancos e softwares dedicados, e estimada a produção de energia elétrica. Esta foi comparada com os dados reais de geração, obtidos através do software de monitoramento dos inversores do sistema, e submetida a testes estatísticos. Para cada amostra foi realizado um estudo econômico, utilizando os conceitos da engenharia econômica. Os resultados mostram que a escolha da metodologia de cálculo das estimativas de geração pode influenciar diretamente nos resultados das análises de viabilidade, o que pode levar a escolhas erradas. Dependendo do tamanho do erro, problemas podem surgir durante a utilização do sistema a curto, médio e longo prazo.
