Using a natural AM1. 5G spectrum to help define an AM1. 5D spectrum appropriate for CPV purposes Conference Paper uri icon


  • Abstract: Spectral measurements were performed of direct beam and global solar irradiance at normal incidence. The measurements were taken at Sede Boqer, during noontime, on a selection of cloudless days during the period December 2001-March 2002. For those days having a low level of diffuse radiation, the ratios of direct beam to global spectra were found to follow a previously suggested, semi-empirical, 2-parameter formula based on Rayleigh scattering. For one of the days, with an unusually high level of diffuse radiation, this …
