Evaluation of uncertainty sources and propagation from irradiance sensors to PV energy production Francesco Mariottini Tom Betts Jiang Zhu Ralph Gottschalg 2134/33092 https://repository.lboro.ac.uk/articles/conference_contribution/Evaluation_of_uncertainty_sources_and_propagation_from_irradiance_sensors_to_PV_energy_production/9555833 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. 2018-05-22 13:38:04 Pyranometer Radiometer calibration Global horizontal irradiance Uncertainty evaluation Data availability Mechanical Engineering not elsewhere classified Photodetectors, Optical Sensors and Solar Cells
