Analysis of the operation of PV strings at the MPP closest to the nominal MPP voltage instead of the global MPP based on measured current–voltage curves

EPJ Photovoltaics, 2022
Under non-uniform operating conditions, photovoltaic (PV) generators may have several maximum power points (MPP) and voltage of the global MPP (GMPP) may vary quickly over a wide voltage range which may cause problems for tracking of the GMPP.

Maximum power point tracking of partially shading PV system using cuckoo search algorithm [PDF]

, 2019
This paper presents a cuckoo search (CS) algorithm for determining the global maximum power point (GMPP) tracking of photovoltaic (PV) under partial shading conditions (PSC). The conventional methods are failed to track the GMPP under PSC, which decrease

A Fast-Tracking Hybrid MPPT Based on Surface-Based Polynomial Fitting and P&O Methods for Solar PV under Partial Shaded Conditions

Mathematics, 2021
The efficiency of photovoltaic (PV) systems depends directly on solar irradiation, so drastic variations in solar exposure will undoubtedly move its maximum power point (MPP). Furthermore, the presence of partial shading conditions (PSCs) generates local

Novel hybrid maximum power point tracking algorithm for PV systems under partially shaded conditions [PDF]

, 2015
Photovoltaic (PV) system has non-linear powervoltage (P-V) characteristic with single maximum power point (MPP) in uniform condition. The P-V curve would be more complicated during partially shaded (PS) conditions (PSCs) when multi-peak powers exist. The

Experimentation, Simulation & Analysis of Partial Shading Effect in Solar Modules

Energy Science &Engineering, Volume 14, Issue 1, Page 4-15, January 2026.
The Master module placed in a non‐shaded and camera view cleaning position, compensates for the loss in power due to partial shading of the slaves, improving the GMP. The enhanced PV voltage across the partially shaded arrangement reduces reverse bias conditions and thermal stress.
