Resumo
O contínuo desenvolvimento e aumento das necessidades energéticas globais, levaram o Homem a procurar novas formas de produzir energia elétrica, recorrendo a fontes de energia renováveis para fazer faces às necessidades. Esta atitude por parte, tem como principais objetivos reduzir a dependência de combustíveis fósseis bem como incrementar uma diminuição dos níveis de poluição resultantes da utilização de combustíveis fósseis. A energia solar fotovoltaica, é a conversão de radiação solar em eletricidade, sendo uma fonte de energia limpa, abundante e renovável com um enorme potencial para satisfazer as necessidades crescentes de eletricidade da humanidade. Do ponto de vista científico é uma área do conhecimento interdisciplinar, com enfâse na física e na química, engenharia de materiais e eletrotécnica. Os sistemas de energia solar fotovoltaica são sistemas capazes de converter a energia solar em potência elétrica para alimentar os demais equipamentos utilizados atualmente, seja em habitações ou em serviços. Esta tecnologia, que se encontra em constante desenvolvimento e com grande margem de progressão no que diz respeito à quantidade de energia produzida com recurso a células fotovoltaicas, tem visto o seu aproveitamento aumentar ao longo dos últimos anos. No que ao caso prático diz respeito, inicialmente foram analisadas as condições do local e os consumos de energia respeitantes à atividade desenvolvida nas Confeções Ómega. Tendo em conta o valor que os proprietários da unidade fabril desejavam investir, foi realizado um estudo acerca do número de módulos possíveis de instalar, disposição dos mesmos na cobertura do edifício, cablagem necessária às ligações e dimensionamento do inversor. Da análise dos resultados obtidos, podemos concluir que o dimensionamento e a solução solar adotada é apropriada à localização, podendo no futuro ser aumentada e reforçar assim o contributo que esta fonte de energia tem nos consumos de energia elétrica da instalação.
Continued development and increasing global energy needs have led humans to look for new ways to produce electricity using renewable energy sources to meet their needs. The main objective of this approach is to reduce dependence on fossil fuels as well as to decrease pollution levels resulting from the use of fossil fuels. Photovoltaic solar energy is the conversion of solar radiation into electricity, being a clean, abundant and renewable energy source with enormous potential to meet the growing electricity needs of humanity. From the scientific point of view, it is an area of interdisciplinary knowledge, with emphasis on physics and chemistry, materials engineering and electrical engineering. Photovoltaic solar energy systems are systems capable of converting solar energy into electrical power to power the other equipment currently used, whether in homes or services. This technology, which is under constant development and with a large margin of progress with regard to the amount of energy produced using photovoltaic cells, has seen its use increase over the last few years. As far the practical case is concerned, initially the conditions of the place and the energy consumption related to the activity developed in the Confeções Ómega were analyzed. Taking in account the value that the plant owners wanted to invest, a study was carried out on the number of modules possible to install, their arrangement on the building's roof, the wiring required for connections and the dimensioning of the inverter. From the analysis of the results obtained, we can conclude that the dimensioning and the adopted solar solution is appropriate to the location and may in the future be increased and thus reinforce the contribution that this energy source has to the electricity consumption of the installation.
