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. date_type: published date: 2013-05 publication: Renewable and Sustainable Energy Reviews volume: 21 pagerange: 248-261 id_number: 10.1016/j.rser.2012.12.033 institution: E_Industrial department: Ingenieria_Electrica refereed: TRUE issn: 1364-0321 official_url: http://www.sciencedirect.com/science/article/pii/S1364032112007368 citation: Antoñanzas Torres, Fernando and Cañizares Jover, Federico and Perpiñan Lamigueiro, Oscar (2013).
