    This Thesis entitled “Electrical characterization of standalone Solar Farm enabled by Graphene-Perovskite based PV panels under various environmental conditions” was written to study the behavior of GRAPEs (Graphene Perovskite solar panels), a new emerging technology in photovoltaics, for the first time at panel size in real outdoor conditions. To determine this behavior, they were studied and measured for the period from January to August 2021 to find out how different parameters and factors affect their electrical properties, efficiency, and long-term lifetime stability. In the following chapters, the construction of the panels, the results of the measurements during this period under different outdoor conditions and all the factors that influence and change their electrical properties are analyzed. Experiments on the light soaking effect were also carried out to study the behavior of the panels, and electrochemical impedance spectroscopy (EIS) measurements were carried out to determine the EEC of this category of photovoltaic (PV) technology and how it is affected by temperature. In addition, the temperature coefficients of the electrical characteristics of this technology were investigated in indoor experiments by taking measurements in a room with controlled environmental conditions. Furthermore, benchmarking between GRAPEs and other solar cells has been carried out to compare the behavior of this technology with other technologies already commercialized and to estimate the expected energy yields of each type of photovoltaic technology. Finally, all the meteorological data for the solar park area recorded by the weather station for the period in which the measurements were taken per month are presented.
