RESUMO:

Partial shading decreases the power generated by solar panel arrangements. In this condition, some panels end up receiving solar radiation different from others, causing multiple peaks in P-V and I-V, resulting in losses. This work aims to reduce the losses caused by partial shading from reconfigurations of the panel arrangements, in conjunction with an adaptive P & O MPPT algorithm. The modeling of the solar panels is carried out in a Matlab & Simulink simulation environment. The modeling of the adaptive MPPT P&O method is also performed. The tested arrangements are of the Total Cross-Tied (TCT), Total Cross-Tied (SP-TCT), Bridge-Linked - Total Cross-Tied (BL-TCT), Bridge-Linked-Honey-Comb (BL-HC), plus a Magic Square (MS) equivalent for each of the arrangements presented. Magic Square is a way to rearrange the solar panels in different positions, in order to mitigate the losses caused by shading. The performances of all configurations are tested for different shading situations and demonstrated from V-P graphics. In addition to the MS, in order to make the system more efficient, it implements the adaptive MPPT P&O that has a faster response time than the standard P&O.
