“…Furthermore, monitoring systems [10][11][12][13][14][15] are often needed in PV plants for collecting power production and performance data [16][17][18] as well as weather information. In this way, it is possible to track the working conditions of each module recognizing faulty units [19,20], preventing mismatch [21] and partial shading, avoiding significant power losses [22] through suitable control actions.…”

Abstract:In order to reduce the mismatch effect caused by non-uniform shadows in PV arrays, reconfigurable interconnections approaches have been recently proposed in the literature. These systems usually require the knowledge of the solar radiation affecting every solar module. The aim of this work is to evaluate the effectiveness of three irradiance estimation approaches in order to define which can be well suited for reconfigurable PV arrays. It is presented a real-time solar irradiance estimation device (IrradEst), implementing the three different estimation methods. The proposed system is based on mathematical models of PV modules enabling to estimate irradiation values by sensing a combination of temperature, voltage and current of a PV module. Experimental results showed generally good agreement between the estimated irradiances and the measurements performed by a standard pyranometer taken as reference. Finally one of the three methods was selected as possible solution for a reconfigurable PV system.
