A new interconnection technique for PV panel cells using cubic topology

Abstract EN

This paper presents a new cells connection topology of the photovoltaic panel.

the idea is to interconnect the cells under a cubic topology.

this configuration will be used to assess the impact of the shading scenarios on the performance of the panel and precisely the influence on the characteristics i-v and p-v.

the cubic and series-parallel configurations are studied using simulation models to compare their performances.

also, we studied their characteristic parameters as a function of the shading variations.

this study concerns the open circuit voltage v, the short-circuit current is, and the maximum power pa, in order to find the best configuration that minimizes the effect of partial shade.

the study of these performances is initiated for different shading scenarios : horizontal, vertical, diagonal, and random shading.

the obtained results show that cubic topology can be considered as a solution for the problem of shading.
