Modeling and detection of hot-spot in shaded photovoltaic cells [PDF]

, 2014
In this paper, we address the problem of modeling the thermal behavior of photovoltaic (PV) cells undergoing a hotspot condition. In case of shading, PV cells may experience a dramatic temperature increase, with consequent reduction of the provided power.

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

Partial shading detection and hotspot prediction in photovoltaic systems based on numerical differentiation and integration of the P − V curves

IET Renewable Power Generation, 2023
Hotspot phenomenon is an expected consequence of long‐term partial shading condition (PSC), which results in early degradation and permanent damage of the shaded cells in the photovoltaic (PV) systems.

Power enhancement in PV arrays under partial shaded conditions with different array configuration

Heliyon
Solar Photovoltaic systems are used for electrical power generation, and they provide an alternative source to non-renewable energy sources like coal, oil, natural gas and nuclear energy. Photovoltaic arrays used in PV systems may be subjected to partial
