Bifacial PV modules are progressively used in a multitude of fields like as building integrated or applied photovoltaic, agrivoltaic systems, and on-field PV plants. The assessment of the power increase generated by bifacial photovoltaic (bPV) modules is essential for the design of installation based on this technology. However, experimental data on the electrical and thermal behavior of bifacial modules are not as widespread as for monofacial modules. In this context, monitoring the operating variables and calculating the performance indices is becoming fundamental to analyze online the module/system efficiency and detecting faulty conditions. The purpose of this paper is to design a monitoring system, which can measure, display, and store weather data (i.e., ambient temperature, irradiances, and wind speed) and electrical parameters (current, voltage, and power). The developed applications allow us to trace the current–voltage curve and track the global maximum power point. An application of the designed monitoring system to a naturally ventilated façade realized with bifacial photovoltaic modules is presented. The realization of a so particular application of bPV module may represent a step forward in the application of this relatively new technology.

Abstract
Bifacial PV modules are progressively used in a multitude of fields like as building integrated or applied photovoltaic, agrivoltaic systems, and on-field PV plants. The assessment of the power increase generated by bifacial photovoltaic (bPV) modules is essential for the design of installation based on this technology. However, experimental data on the electrical and thermal behavior of bifacial modules are not as widespread as for monofacial modules. In this context, monitoring the operating variables and calculating the performance indices is becoming fundamental to analyze online the module/system efficiency and detecting faulty conditions. The purpose of this paper is to design a monitoring system, which can measure, display, and store weather data (i.e., ambient temperature, irradiances, and wind speed) and electrical parameters (current, voltage, and power). The developed applications allow us to trace the current–voltage curve and track the global maximum power point. An application of the designed monitoring system to a naturally ventilated façade realized with bifacial photovoltaic modules is presented. The realization of a so particular application of bPV module may represent a step forward in the application of this relatively new technology.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
