O presente Trabalho de Conclusão de Curso trata da análise dos fatores que influenciam as perdas de eficiência em um sistema de microgeração fotovoltaica, verificando os fatores de perda de eficiência, abordando as propriedades relacionadas à conversão fotovoltaica, à degradação dos componentes, às condições ambientais e operacionais, bem como à manutenção e monitoramento adequados. Assim, esta pesquisa tem como objetivo realizar uma análise dos fatores de perda de eficiência na microgeração fotovoltaica, a fim de apresentar uma perspectiva abrangente dos obstáculos enfrentados pelos sistemas de microgeração fotovoltaica e propor estratégias para mitigar as perdas, bem como otimizar a produção, eficiência e confiabilidade dos sistemas de geração fotovoltaica, contribuindo para uma geração de energia mais eficiente e confiável. Durante a pesquisa, foram identificados e analisados sete principais fatores de perda de eficiência em sistemas fotovoltaicos. O Sistema 1 apresentou a menor perda percentual, aproximando-se de um sistema ideal. Já os Sistemas 2 e 3 mostraram somas percentuais de perda semelhantes, porém com causas predominantes diferentes: a maior perda no Sistema 2 foi devido à eficiência dos inversores, enquanto no Sistema 3 foi a sujidade dos módulos. Esses achados destacam a interação complexa entre variáveis ambientais, tecnológicas e operacionais, ressaltando a necessidade de abordagens personalizadas para mitigar perdas e melhorar a eficiência e viabilidade econômica da microgeração fotovoltaica.
This Course Completion Work deals with the analysis of the factors that influence efficiency losses in a photovoltaic microgeneration system, verifying the efficiency loss factors, addressing the properties related to photovoltaic conversion, component handling, environmental conditions and operational, as well as maintenance and adequate monitoring. Thus, this research aims to carry out an analysis of efficiency loss factors in photovoltaic microgeneration, in order to present a comprehensive perspective of the obstacles faced by photovoltaic microgeneration systems and propose strategies to mitigate losses, as well as improve production, efficiency and reliability of photovoltaic generation systems, contributing to more efficient and reliable energy generation. During the research, seven main factors of loss of efficiency in photovoltaic systems were identified and analyzed. System 1 showed the lowest percentage loss, approaching an ideal system. Systems 2 and 3 showed similar loss percentages, but with predominantly different causes: the biggest loss in System 2 was due to the efficiency of investors, while in System 3 it was the dirt of the modules. These findings highlight the complex interaction between environmental, technological and operational variables, highlighting the need for specific approaches to mitigate losses and improve the efficiency and economic forecast of photovoltaic microgeneration.
