An Algorithm for Enhanced Performance of Photovoltaic Array Under Partial Shading Condition

IEEE Access, 2020
The partial shading on photovoltaic (PV) modules causes a reduction in generated power and multiple peak points in their electrical characteristics. If the number of shaded modules of two or more rows are different then electrical characteristics exhibit

Maximizing Power Output of a Partially Shaded Total-Cross-Tied Photovoltaic array

Transactions on Environment and Electrical Engineering, 2017
Non-uniform conditions on the modules of the PV array, especially, partial shading reduces the output of the PV array to a large extent. The shaded module in a string limits the current of the entire string and hence, the output power of the string.

Enhanced power generation for total‐cross‐tied PV array using simulated annealing under partial shading conditions

IET Renewable Power Generation, 2020
Shade phenomena affect the PV module's power output, introduce multiple peak points in PV characteristics, and shorten the expected life cycle of the module. In order to prevent this issue, PV modules should reconfigure, namely, altering the electrical connections between PV modules based on the irradiance without changing their physical locations.
