Comparative assessment of global irradiation from a satellite estimate model (CM SAF) and on-ground measurements (SIAR): a Spanish case study
An analysis and comparison of daily and yearly solar irradiation from the satellite CM SAF
database and a set of 301 stations from the Spanish SIAR network is performed using data of
2010 and 2011. This analysis is completed with the comparison of the estimations of effective
irradiation incident on three different tilted planes (fixed, two axis tracking, north-south hori-
zontal axis) using irradiation from these two data sources. Finally, a new map of yearly values
of irradiation both on the horizontal plane and on inclined planes is produced mixing both
sources with geostatistical techniques (kriging with external drift, KED)
The Mean Absolute Difference (MAD) between CM SAF and SIAR is approximately 4% for
the irradiation on the horizontal plane and is comprised between 5% and 6% for the irradiation
incident on the inclined planes. The MAD between KED and SIAR, and KED and CM SAF is
approximately 3% for the irradiation on the horizontal plane and is comprised between 3% and
4% for the irradiation incident on the inclined planes.
The methods have been implemented using free software, available as supplementary ma-
terial, and the data sources are freely available without restrictions
