Análise das tecnologias de módulos fotovoltaicos Fullcell e Halfcell

Abstract

In this work the difference between the fullcell and halfcell module technology was studied in three different shading cases. For this study, was used the Matlab Simulink simulation environment, where the mathematical equations of the photovoltaic cell were used for ride one fullcell module and one halfcell module. Two commercial modules from the Resun brand have been chosen, one was the monocrystalline 400Wp Resun RS6S-M, made of 72 photovoltaic cells with fullcell technology, and the other was the 400Wp monocrystalline Resun RS6I-M, made of 144 photovoltaic cells with the halfcell technology. The two modules were chosen because they are from the same brand, same generation power and same semiconductor features (monocrystalline silicon), so, the difference between the modules are the construction, photovoltaic cell features, and fullcell or halfcell technology, providing a fair comparison between the two technologies. The chosen model presented a good precision, with a maximum error of 5% when compared with the manufacturer datasheet. When the three cases of shading were studied, the halfcell module was more efficient, with 9,5%, 14,1% and 36,2% of more power when compared with the fullcell module for the case 1, case 2 and case 3.
