Efficient Photovoltaic System Maximum Power Point Tracking Using a New Technique

Energies, 2016
Partial shading is an unavoidable condition which significantly reduces the efficiency and stability of a photovoltaic (PV) system. When partial shading occurs the system has multiple-peak output power characteristics.
