One of the most important concerns of the energy policy is solar energy systems education and promoting solar energy applications for sustainable development. The photovoltaic panel converts solar energy to electricity and represents the main element of a photovoltaic system. Studying the characteristic curve of a panel is essential in the study of photovoltaics since it provides important details about the electrical characteristics of the panel and it is used for simulation, design, and performance analysis of photovoltaic systems.

Thus, the assessment of the effectiveness of a photovoltaic module requires knowledge of its characteristic curve.
