Abstract
This paper presents an investigation into the variation of the performance of a PV module under different patterns of partial shading with variation in the number of bypass diodes. The investigation was performed using a MATLAB/Simulink simulation approach, which mitigates the need for complex numerical techniques. The single-diode model of a PV cell was used in the modelling. The performance is assessed in terms of the global maximum power yield and the number of local power peaks in the power-voltage characteristic of the PV module. Results indicate that increasing the number of bypass diodes can improve the energy yield of a module at the expense of increasing the number of local power peaks in the power-voltage curve. It is also found that the latter depends, not only on the pattern of partial shading, but also on its severity.
