Comparison among photovoltaic technologies: An experimental case study

This paper deals with the experimental comparison among the performance indexes of different photovoltaic technologies, which are obtained by means of a specifically designed monitoring system. A description of the monitoring system is provided by focusing attention towards its metrological management, which allows traceable results to be obtained that are qualified in terms of measurement uncertainty. Preliminary results are also described for a photovoltaic plant that includes ten sub-plants based on different technologies. Reported results refer to a time interval of nine months.
