Impact of Uneven Shading by Neighboring Buildings and Clouds on the Conventional and Hybrid Configurations of Roof-Top PV Arrays

IEEE Access, 2021
Partial shading is the commonly encountered scenario of building roof-top based PV arrays that mainly occur due to the shadow of the neighbouring buildings and clouds resulting in unexpected losses and deteriorated system performance.

L-Shape Propagated Array Configuration With Dynamic Reconfiguration Algorithm for Enhancing Energy Conversion Rate of Partial Shaded Photovoltaic Systems

IEEE Access, 2021
Partial shading is an unavoidable factor that reduces the performance of solar PV systems. The PV system receives uneven irradiation due to partial shading which causes the mismatch loss.

Hybrid interconnection schemes for output power enhancement of solar photovoltaic array under partial shading conditions

IET Renewable Power Generation, 2022
Partial shading conditions (PSC) across the solar photovoltaic (PV) array reduce the overall power yield of the PV plant. Therefore, it is essential to decrease mismatch power loss (MPL) incurred under PSC. For this purpose, total‐cross‐tied (TCT)‐based ‘

A Novel Benzene Structured Array Configuration for Harnessing Maximum Power From PV Array Under Partial Shading Condition With Reduced Number of Cross Ties

IEEE Access, 2022
Partial shading (PS) phenomena significantly degrade the power output from the photovoltaic (PV) array. Due to the PS effect, there is a mismatch in current between the PV modules of a series-connected PV string.
