An Experimental Plant of Photovoltaic Modules in the Palermo's University Campus: Analysis of the First Annuity's Data and Validation of a Rough Model of PV Converters

摘要

With the following report we present the data collected in the Oct. 2001- Oct.2002 period on several PV modules installed at Palermo University. The PV cells were mounted on the cover of a footbridge connecting two departments. The covered surface is approximately 25 m2. The system was connected to the public distribution network and the exchanged energy was continuously measured. The data acquisition system measured the total solar radiation, the ambient temperature, the module temperature and the produced energy. We also studied a valid numerical model to describe the effect of changes on the cell temperature on the conversion efficiency of the PV modules in special conditions and validated the model through the collected data.
