The efficiency of these systems relies upon determining the intensity of solar irradiation considering solar energy serves as both the foundation for the system and the main power source for numerous varieties of renewable energy systems. In the prior ten years, research has been concentrating on finding electric energy sources whose services can meet society's expanding demands while having little environmental effect and high effectiveness [1]. The existence of clouds in the sky, however, is the most unpredictable aspect that interferes with catching solar irradiation and prevents a good conversion of sunlight into power [1]. Numerous approaches to tracking and forecasting irradiation have been put forth for enhancing the effectiveness of photovoltaic cells ability to produce energy. The penetration level of solar photo voltaic generation (SPVG) must be boosted in order to satisfy the growing need for electricity [3]. It might compromise the system's stability and security, leading to problems with power quality, inadequate protection coordination, and reverse power flow, to name a few [3]. The study investigates how the PV model responds to various levels of solar irradiation as a result of environmental factors. Processing the measurements with a mathematical model of a photovoltaic cell in conjunction with a PI controller yields an estimate of the solar irradiation.
