Photovoltaic (PV) systems, leveraging the photoelectric conversion of solar radiation into electrical energy, have undergone substantial technological advancements in recent decades. These advancements have yielded increased conversion efficiencies and an expansion of large-scale deployments, ranging from utility-scale power plants to in-situ distributed micro-systems. This paper presents a technical analysis of the efficiency of terrestrial photovoltaic (PV) panels. The study evaluates their power performance, focusing on the variable factors that introduce uncertainty in predicting incident solar radiation and its subsequent conversion into electrical energy. Consequently, to optimize the operating point of a photovoltaic (PV) system intended for powering an in-situ Internet of Things (IoT) station, a focused laboratory investigation is necessary. This study aims to determine the optimal utilization of a specific solar panel for powering a soil characteristic monitoring station. Furthermore, this paper will explore the potential and evolutionary trends of IoT applications, encompassing communication technologies and air-to-ground sensors, in enhancing the operating point of in-situ mounted PV systems. The results demonstrate the suitability of the proposed PV system for the autonomous powering of the soil monitoring station. This presents a promising solution for realizing an autonomous IoT pilot station, integrating a solar photovoltaic system for intelligent remote and real-time monitoring of soil parameters.
