Photovoltaic Model Uncertainties Based on Field Measurements. Makrides, G., Zinsser, B., Phinikarides, A., Norton, M., Georghiou, G. E, Schubert, M., & Werner, J. H In 37th IEEE PVSC, pages 2386–2390, Seattle, WA, 2011. doi abstract bibtex Mathematical and empirical models have long been used to describe the output behaviour of photovoltaic (PV) systems. The purpose of this paper is to compare the combined uncertainties inherent in the results when using three of these models; the single-point efficiency, the single-point efficiency with temperature correction and the PVUSA model. This evaluation was performed using outdoor measurement data from 12 different grid- connected PV systems of 1 kWp each, operating in Cyprus since June 2006 along with measurement data from the meteorological sensor network on-site. The models showed a wide variation in combined uncertainties, demonstrating the dependence of accurate energy yield predictions on the model and sensing equipment. In particular, it was shown that the application of temperature correction on the single-point efficiency model using the manufacturer provided temperature coefficients ($\ gamma$MPP) resulted in a reduction of the combined uncertainty. In the case of the single-point efficiency model, the uncertainties were in the name-plate efficiency at standard test conditions ($\ eta$STC) and the global irradiation measured on the plane of array (GPOA), producing a combined uncertainty of $±$7\%\ on the annual dc energy yield of all PV systems. By applying temperature correction on the model, the combined uncertainties dropped to an average of $±$5.60\%\, despite the introduction of additional uncertainties from $\ gamma$MPP and Tmodule. Lastly, the PVUSA model showed even lower combined uncertainties, in the realm of $±$1.60\%\. The paper also presents the combined uncertainties inherent in the three models separately for four different years (2006-2007, 2007-2008, 2008-2009 and 2009-2010).
