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

This paper presents the performance indices with total nominal array power of 0.9 kWp Grid-Connected Photovoltaic (GCPV) system using amorphous-Silicon (a-Si) for the first year of operation in Malaysia. Since operation, a-Si GC system injected into the grid with the total energy production about 1,138.2 kWh. In addition, the annual array yield, final yield, and inverter efficiency were operated at 1,401 kWh/kWp, 1,261 kWh/kWp, and 90.2 %, respectively. The operation of a-Si GC system indicates that the system was operated well with the measured performance ratio at 85 % during the study period.
