Twisted Two-Step Arrangement for Maximum Power Extraction From a Partially Shaded PV Array

IEEE Journal of Photovoltaics, 2022
Partial shading is one of the biggest challenges in the optimum utilization of photovoltaic (PV) panels. Occurrence of shade on the front side of a panel affects the light transmission completely or partially, leading to its production loss.
