Comparação técnico-económica entre sistemas com inversores centrais e sistemas com inversores string

Abstract

Devido ao aumento da importância da energia solar a nível mundial e à crescente demanda energética, tem-se verificado uma contínua aposta em parques fotovoltaicos cada vez maiores por todo o mundo, sendo necessário otimizar cada vez mais as soluções para que a eficiência seja maior e consequentemente o lucro também. Contudo, em países onde fatores de radiação, temperatura, condições climatéricas e de construção, vão influenciar a decisão na escolha do sistema de inversor, há que escolher a mais acertada. Foi realizado um estudo para quatro geografias distintas (Chile, Índia, Portugal e Roménia) e três potências diferentes (1MW, 7.5MW e 15MW) das instalações fotovoltaicas para cada país, sendo ainda estudado para cada país e potência dois tipos de sistema: inversor central e inversor string. Foi simulada a produção e dimensionada toda a instalação para cada caso. Neste estudo comparou-se a produção específica e custo final da instalação por watt pico para cada país e potência em cada tipo de sistema. Verifica-se uma relação entre o tipo de sistema a selecionar e a geografia da instalação.
