Abstract
The power produced from solar panels depends on irradiation, temperatures, number of cells, and aging impact. Moreover, extracting maximum power from solar cells is independent of load. Therefore, a maximum power point tracker (MPPT) is essential to maximize the output power from a photovoltaic (PV) module. The incremental conductance, and the equilibration algorithms have been applied to extract the MPP under partial shading condition. Partial shading on solar panels causes the power-voltage curve to have different local maximal points Among them, the largest MPP, the global maximum point, should be extracted. In this paper, a multiple-input single-ended primary inductance converter (SEPIC) is chosen to combine PV modules with an alternative source because it provides a continuous input current, and full MPP tracking range.
