Abstract(s)
As crises energéticas surgidas no decorrer do último século, incluindo a crise do petróleo, obrigaram o Homem a, cada vez mais, procurar fontes de energia alternativas e preferencialmente inesgotáveis. Desta situação, resultou uma forte aposta na exploração das fontes de energias renováveis, que são uma das principais alternativas para responder a um aumento de procura, e também, além disso, face às exigências de consumos actuais, a aposta numa energia limpa e renovável promove uma forte redução dos impactos ambientais associados ao seu consumo e que outras fontes de energia não apresentam.
Sendo a energia solar relativamente bem distribuída pela superfície habitada da Terra, é uma das mais promissoras formas de energia renovável. Nas últimas décadas tem tido um enorme crescimento a nível mundial, com diversos programas governamentais a incentivarem a instalação destes sistemas.
Este trabalho teve como principal objectivo demostrar como o efeito do sombreamento afecta o desempenho dos módulos fotovoltaicos e comparar o comportamento de dois modelos matemáticos da célula fotovoltaica.
Abstract: The energetic crisis that occurred during the last century, including the oil crisis, forced Man to search for more alternative energy sources and preferably inexhaustible ones. From this situation resulted a strong bet on renewable energy sources exploration, which are one of the main alternatives to respond to the increased demand and also to meet the requirements of the current energy consumption. When betting in a clean and renewable energy we benefit from a stronger reduction in environmental impact that other energy sources do not provide. Being solar energy, relatively well distributed over the inhabited earth is one of the most promising forms of renewable energy. In the last few decades has had a huge growth worldwide, with many government programs to encourage the installation of these systems. The aim of this thesis was to demonstrate the effect of shading effects on the performance of photovoltaic modules, and compare the performance of two mathematical models of the photovoltaic cell.
