Monitoring the performance of single and triple junction amorphous silicon modules in two building integrated photovoltaic (BIPV) installations
Özet
Mugla is located in south west Turkey at 37 degrees 13'N latitude and 28 degrees 36'E longitude with yearly sum of horizontal global irradiation exceeding 1700 kWh per square meter. Mugla has a Mediterranean Climate which is characterized by long, hot and dry summers with cool and wet winters. Mugla Sitki Kocman University is the largest "PV Park" in Turkey consisting of 100 kWp installed Photovoltaic Power Systems (PVPSs) with different PV applications. The 40 kWp building integrated photovoltaic (BIPV) system which is the first and largest in Turkey was installed on the facade and the two towers of the "Staff Block of the Education Faculty's Building" of Mugla Sitki Kocman University in February 2008. Triple junction amorphous silicon photovoltaic modules are used on the facade and single junction amorphous silicon PV modules are used on the East and West towers of the building. In this paper, the 40 kWp BIPV system in Mugla, Turkey is presented, and its performance is evaluated. Energy rating (kW h/kWp energy yield), efficiencies and performance ratios of both applications are also evaluated for 36 months of operation. Daily, monthly and seasonal variations in performance parameters of the BIPV system in relation to solar data and meteorological parameters and outdoor performance of two reference modules (representing the modules on facade and towers) in a summer and a winter day are also investigated.
