Two-year performance monitoring of amorphous-Silicon Grid-Connected Photovoltaic system

Abstract

This paper presents the thin-film performance with a total nominal array of 0.9 kWp Grid-Connected Photovoltaic system using single-junction amorphous-Silicon for two years of operation in Malaysia. Since the operation, the system has injected into the Tenaga Nasional Berhad's grid with the total energy production of about 2,232.8 kWh. Additionally, the daily average for the final PV system yield, the efficiencies of system and inverter were recorded at 3.39 kWh/kWp.d, 5.08% and 89.6%, respectively. The daily operation showed that it has been operating in better condition under Malaysian climate with the performance ratio measured at 80.6% during the monitored period.
