Energy Yield Estimation, Installation and Monitoring of 3-Phase Grid Connected PV System

This paper describes installation and analysis of photovoltaic system (PV) which has been installed in Soke/Aydin, Turkey. Generally, the PV systems are installed on roof according to inclination of roof as well north facade. Therefore, large losses occur. In order to minimize losses, for the first time in Turkey the PV panels were placed both on North and South facade with 15 and 10 degree angle to the South, contrary to traditional roof installed PV systems. In this way it was determined that efficiency of PV panels especially the ones that are positioned at North facade were increased by 10%. The simulation of the system was done using different sun irradiation sources such as Geomodel, Meteocontrol, Meteonom and PVGIS. The total DC power of the system is 155.3 kWp. Annual electricity production amount and performance ratio was calculated as 243 MWh and 80.9% respectively for the first year. The uncertainty of the models and calculation steps with respect to the average specific yield and average yield is estimated to be ± 7.1% assuming a simple standard deviation. The PV system has produced 50.522 kWh energy from January to April, 2014.
