Comparison analysis of measured and estimated yield of grid-connected PV system

This paper presents estimated and measured yield of grid-connected photovoltaic (PV) system using performance estimation yield model with two year monitored data. The accuracy and validity of this estimation method is identified by compared measured with estimated value for long-term operation. These results will indicate that it is useful to estimate various loss factors causing the system performance obstruction and enhance the lifetime yield of PV system.
