Spectral influences on estimations of useful irradiance for different PV technologies
conference contribution
posted on 2011-03-09, 11:32 authored by Michal Krawczynski, Matthias Strobel, Tom BettsTom Betts, Ralph GottschalgReference solar irradiance is the most
influential parameters for accuracy of PV
systems monitoring. Due to new cells
technologies a magnitude of spectral
effects is widely discussed nowadays. No
comprehensive measurements are taken
to resolve this debate. This paper discuss
utilization of the spectral measurements in
a PV system monitoring. Analysed data
come from dedicated monitoring systems
and include broadband and spectral
irradiance, module short circuit current,
module temperature, ambient temperature
humidity and wind-speed. It has been
shown what are the variations in the solar
spectrum over the different types of
overcast and how does the different
module technologies react on those
changes. Investigating distribution of the
solar spectral irradiance is a complex task.
Conclusions discuss usability of the
spectroradiometers as the reference
sensors and problems that still stays
unsolved in the field of spectroradiometry.
