32nd European Photovoltaic Solar Energy Conference and Exhibition; 1385-1389, The aim of this work is to report the results of the main characterization activities carried out on the ECOSOLE HCPV prototypal plant realized by BECAR s.r.l. and installed at ENEA Research Center located at Portici in the south of Italy. After a detailed description of the system main components, the experimental results regarding the module characterizations, the tracker accuracy, the system optical acceptance, and the module temperature survey are detailed. The second part of the paper is focused on the explanation of the performance analysis carried out on the basis of the data collected during the first three months of operation. Particular attention has been paid to the performance comparison of the two sub-arrays of the plant: the first one is realized with module using each one its-own inverter, and the second one is realized with a classic centralized inverter solution. At the end, a procedure for a detailed losses analysis is reported and the results obtained for a whole sunny day are explained.

28th European Photovoltaic Solar Energy Conference and Exhibition; 664-667, This work deals with the thermal analysis of the heat sink relative to a novel high-concentrating photovoltaic system developed in the framework of the European project ECOSOLE. The thermal analysis has been performed taking into consideration two different conditions, namely the worst condition that occurs when the module doesn’t produce energy and the tracker is in perfect alignment with the sun, and the design conditions with the module operating in its MPPT. 3D numerical simulations have been performed using the commercial software Comsol Multiphysics in order to evaluate the temperatures maps relative to the cell and the heat sink in both the considered conditions. Furthermore, the thermo-fluid-dynamics of the air inside and around the HCPV module frame have been characterized by means of 3D numerical simulation performed using the commercial software ANSYS Fluent.

This paper reports the results of a performance analysis carried out by ENEA on a CPV system, produced by BECAR srl within a European collaborative Project named ECOSOLE, and installed at ENEA Research Center of Portici. Modules degradation after two operation years has been evaluated by means of detailed characterizations; tracker system accuracy has been monitored using a specific opto-electronic device. System performances during the period has been analysed based on the production and weather data: a deep performance analysis has been carried out in order to quantify the main losses causes in DC side. The behaviours of the two sub-fields of the system, the first one realized with one centralized inverter for 16 modules and the second one with 16 modules having each one its own inverter, have been compared from technical and economical point of view.This paper reports the results of a performance analysis carried out by ENEA on a CPV system, produced by BECAR srl within a European collaborative Project named ECOSOLE, and installed at ENEA Research Center of Portici.

This paper reports the results of an experimental campaign carried out by ENEA on an innovative CPV system, produced by BECAR srl within an European collaborative Project named ECOSOLE, and installed at ENEA Research Center of Portici. The system is deeply described together with the monitoring system used to record weather and energetic parameters useful to perform a complete performance analysis of the Plant. The results of the module characterization and of the calculation of the main performance indices are detailed. © 2016, American Institute of Physics Inc. All rights reserved.

ECOSOLE is an European collaborative Project started in August 2012 that involves several industrial and institutional partners with the aim to develop a complete and innovative concentrating photovoltaic system. During the first two years of activity, several specific components as cells, optics, modules and tracker have been designed and developed. This work reports the description of these devices and the main results of the characterization campaigns carried out to define their technical features. © 2015 AIP Publishing LLC.
