Abstract
In this paper, we introduce a detailed photovoltaic panel (PV) model that includes Bishop circuit representation for the hot spot phenomena. The hot spot phenomenon is considered as preliminary damage occurring in solar panels. The main reasons are shading and possibly dust accumulation. The hot spot reduces the output power of the panel and it life time. The developed model was based on Matlab /Simulink tool. The model simulation results confirm the shading rate control on the amount output power. The hot spot, current distribution detailed picture was reached under several testing conditions. The presented detailed has shown its capability to follow the switching action of the bypass diode during the event of shading in a panel string. The details about shunt current, string current and bypass diode current along with the corresponding power dissipation in a panel string are newly introduced in this work.
