Abstract: Shadowing effect occurs when a photovoltaic system does not receive the same amount of incident irradiation level throughout the system due to obstacles. In these conditions, the cells receiving a lower level of irradiance can absorb power instead of producing it.

Partial shadowing is caused by surrounding objects casting shade on a portion of a photovoltaic (PV) array, resulting in non-uniform irradiance to the PV modules. Non-uniform shading results in an electrical mismatch between array members, resulting in a non-linear loss in energy collection.

The shading effect in photovoltaic panels affects the production of electrical energy by reducing it or even causing the destruction of some or all of the panels.

This research examines the performance calculation of different shading on PV panel under the energy-exergy analysis method. In this study, for static shading, a non-transparent substance and powder were utilized, and for dynamic shading, a chimney's time-varying shading effect was applied to the system.

Circuit-based methodologies enable the identification of cell actions as a portion of system, particularly when shading effects are present. An I source antiparallel with diode could be used to simulate the appropriate solar panel. The source's DC is indeed a part of irradiance just on the upper part of PV.
