Investigation on Impact of Partial Shading on Solar PV Array

Partial shading can have a significant impact on the output of a photovoltaic system. The nature of the functioning of photovoltaic systems, which rely on solar irradiation to make electricity, leads to the implicit belief that the maximum power of a partially shaded system always drops as the system gets darker. Although it has been indicated in the literature that this may not be the case, When a critical point is reached, partial shading patterns may become quite resistant to shading heaviness, allowing a solar-photovoltaic system to produce its maximum power even when partially shaded. This research looks at how the introduction of partial shading affects the locus of interest.
