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.

Analysis of Dynamic Characteristic for Solar Arrays in Series and Global Maximum Power Point Tracking Based on Optimal Initial Value Incremental Conductance Strategy under Partially Shaded Conditions

Energies, 2017
Partial shading (PS) is an unavoidable condition which significantly reduces the efficiency and stability of a photovoltaic (PV) system. With PS, the system usually exhibits multiple-peak output power characteristics, but single-peak is also possible ...

Performance analysis of PV array configurations (SP, BL, HC and TT) to enhance maximum power under non‐uniform shading conditions

Engineering Reports, 2020
Partial shading condition (PSC) causes the significant increase in power losses of solar photovoltaic arrays. Partial shading is due to the shadows of passing clouds, chimneys, trees, bird droppings, various tall building structures etc. At the PSCs, the
