Reconfiguration Method to Extract More Power from Partially Shaded Photovoltaic Arrays with Series-Parallel Topology

Energies, 2019
A photovoltaic (PV) array is composed of several panels connected in series-parallel topology in most actual applications. However, partial shading of a PV array can dramatically reduce power generation.

A Novel Array Configuration Technique for Improving the Power Output of the Partial Shaded Photovoltaic System

IEEE Access, 2022
Power conversion efficiency is the most important factor to be considered in PV systems because it is affected by various environmental conditions. The effect of partial shading is the most influenced factor in the reduction of power output.

Automatic PV Array Reconfiguration under Partial Shading Conditions

NTU Journal of Renewable Energy, 2023
Photovoltaic (PV) arrays have been recognized as one of the main clean renewable sources of electrical energy. In practice, PV arrays are subject to unavoidable non-uniform partial shading (PS) due to clouds, buildings, dust, etc. PS causes the hot spot problem, mismatch losses, and output power degradation.

A PV Array Reconfiguration Algorithm for Minimising Partial Shading Effects [PDF]

2019 10th International Renewable Energy Congress (IREC), 2019
A photovoltaic array is subject to reduction of output caused by partial shading which causes bypass diodes to turn on. This can be alleviated by partly or fully cross-tying the modules within the rows of the array, and reconfiguring the positions of modules within it.
