An Algorithm for Enhanced Performance of Photovoltaic Array Under Partial Shading Condition

IEEE Access, 2020
The partial shading on photovoltaic (PV) modules causes a reduction in generated power and multiple peak points in their electrical characteristics. If the number of shaded modules of two or more rows are different then electrical characteristics exhibit
