MARIOTTINI, F. ... et al, 2018. Evaluation of uncertainty sources and propagation from irradiance sensors to PV energy production. IN: Proceedings of the 14th Photovoltaic Science, Applications and Technology Conference (PVSAT-14), London, UK, 18-19 April 2018.
This work quantifies the uncertainties of a pyranometer. Sensitivity to errors is analysed regarding the effects generated by adopting different time resolutions. Estimation of irradiance measurand and error is extended throughout an annual data set. This study represents an attempt to provide a more exhaustive overview of both systematic (i.e. physical) and random uncertainties in the evaluation of pyranometer measurements. Starting from expanded uncertainty in a monitored pyranometer, the study concludes with an evaluation of its impact on the estimation uncertainty in the performance of a photovoltaics (PV) solar farm.
