Abstract

In this study, operation and performance of grid-connected solar photovoltaic (PV) power system installed in Kocaeli University are presented. The grid-connected PV power system consists of 720 Wp thin-film PV panels, a 1 kW grid-connected inverter and a WebBox for internet connection. The PV system has been installed first 360 Wp in March 2010 and upgraded for 720 Wp in August 2011. Each has a power of 60 Wp Kaneka thin-film solar panels are installed in the PV system. The SMA Sunny Boy single-phase 1 kW grid-connected inverter is connected to perform the conversion of the direct current generated by the PV panels into mains standard alternating current. The power, voltage and current harmonic values at grid side of the inverter have been measured using Fluke 434 power quality analyzer. After March 2012, the PV system has Internet connection via SMA Sunny WebBox. The produced PV electric energy amount can be monitored in our department website (http://enerji.kocaeli.edu.tr) in hourly, daily and monthly basis.
