Advancements in PV Array Reconfiguration Techniques: Review Article

IEEE Access
Shadowing is a pervasive and complex issue that negatively impacts the performance of photovoltaic (PV) systems by causing a substantial reduction in output power and producing multiple power peaks in characteristic curves. These negative impacts are not

PV array reconfiguration method under partial shading conditions

International Journal of Electrical Power and Energy Systems, 2014
Abstract This paper proposes a new reconfiguration method for photovoltaic arrays under partial shading conditions. With the application the method, the array can produce higher power by reconfigured connections of array. In the proposed method, each row of an array is formed by connecting the panels with close short circuit current levels as ...

Performance of PV array configurations under dynamic partial shadings

EPJ Photovoltaics, 2023
The partial shading effect (PSE) is responsible for most power losses in a photovoltaic (PV) system. By modifying the interconnections between PV modules, called PV array reconfiguration, it is possible to improve the power output under partial shading ...

An Experimental Investigation on Output Power Enhancement With Offline Reconfiguration for Non-Uniform Aging Photovoltaic Array to Maximise Economic Benefit

IEEE Access, 2021
There are several non-uniform effects on photovoltaic (PV) modules related to aging in a PV array. These subsequently bring about non-uniform operating parameters with individual PV modules, causing a variance in the PV array performance.
