Review Mitigation Methods of Partial Shading Condition for PV System

Photovoltaic (PV) systems are becoming more popular for use both off-grid and linked to the power grid. These systems are static, flexible, and good for the environment. They also turn light from the sun, which is a clean, green energy source, into electrical energy. Because of optical and electrical losses, the PV system is less efficient, even though the energy transfer happens instantly. The optical loss caused by partial shading decreases a PV system output greatly, if not properly mitigated. Partial Shading condition (PSC) mitigation strategies are essential components of the power conditioning unit in all big PV systems. These mitigation strategies guarantee that solar energy systems can operate at their full efficiency even when faced with negative partial shadowing. Thus, the purpose of this work is to demonstrate the most advanced shade mitigation approaches currently in use.
