Decade Performance of a Roof-Mounted Photovoltaic Array Conference Paper uri icon


  • The Georgia Institute of Technology's Aquatic's Center is equipped with a 342kW roof-mounted photovoltaic array. This array will reach its ten year anniversary in July of 2006. It is therefore an appropriate time to review its performance. This system is closely monitored and studied with the help of a data acquisition system. Data collected from this system is stored and analyzed. Meteorogical parameters such as plane of array insolation are analyzed and compared with predicted values. Additionally, system parameters such as AC energy production, system efficiency, and module temperature are also monitored. The relationship between certain parameters, such as inverter efficiency and inverter loading, are also examined. With the collected data, the reliability of the system may be analyzed using data from system downtimes. From the analysis, we conclude that the system is operating well and in line with expectations. 2006 IEEE.
