A novel PV array configuration for enhancing maximum power from PV array

Clean Energy, 2022
Abstract Partial shading conditions (PSC) are unavoidable and are the main reason for the reduction in power from a photovoltaic (PV) array. With proper arrangement, the impact of PSC can be somewhat mitigated. There are distinct types of configurations, including series, parallel, series-parallel (SP), honeycomb, total cross-tied (TCT),

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.
