Abstract :
This work experimentally evaluates some of the most referenced methods to estimate the global irradiance incident on tilted surfaces from measured global horizontal irradiance. Angular and spectral effects are also considered for the estimation of the "effective irradiance" to be used by PV modules in PV installations. Angular effects of pyranometers on horizontal surface irradiance measurements and their influence in tilted irradiance estimation are also analysed.
