Performance analysis of PV array configurations (SP, BL, HC and TT) to enhance maximum power under non‐uniform shading conditions

Engineering Reports, 2020
Partial shading condition (PSC) causes the significant increase in power losses of solar photovoltaic arrays. Partial shading is due to the shadows of passing clouds, chimneys, trees, bird droppings, various tall building structures etc. At the PSCs, the
