“Parameter extraction” refers to identifying the key electrical parameters such as series resistance, shunt resistance, diode ideality factor, photocurrent, and saturation current in the single- and double-diode photovoltaic models, based on current–voltage (I–V) characteristics. . In the world of solar technology, precisely extracting photovoltaic cell and panel parameters is key to efficient energy production. The operation of these optoelectronic component is often described by the I-V characteristic, which depends on several electrical parameters [1-3]. Accurately determining these parameters remains a. . This paper presents a new method for parameter extraction in PV systems, specifically single- and three-junction solar modules. Someof these factors are the intensity and the spectral composition of illumination as well as the ambient temperature together with the temperature and contamination of the solar panel and the atmosphere.
