Sources of uncertainty in annual global horizontal irradiance data [PDF]

open access: yesSolar Energy, 2018
Abstract The major sources of uncertainty in short-term assessment of global horizontal radiation (G) are the pyranometer type and their operation conditions for measurements, whereas the modeling approach and the geographic location are critical for estimations.
