Monitoring Electrical and Weather Parameters in Photovoltaic Bifacial Systems

Currently, photovoltaic technology (PV) is moving towards technologies that improve the yields for a given resource, such as PV bifacial modules. The behavior and the measured data are not as widespread as mono-facial technology. Integration of bifacial photovoltaic modules into a building with natural ventilated façade may represent a step forward in the application of this relatively new technology. In this sense, monitoring the crucial parameters in order to analyse module/system performance is becoming crucial. The purpose of this paper is to design a monitoring system for bifacial modules, which can measure, display and store weather (ambient temperature, rear and front irradiances and wind speed) and electrical (current and voltage) parameters. The developed applications allow both; trace the current–voltage curve and track the global maximum power point algorithm.
