Analysis of Ecosole HCPV system performances during two operation years

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.
