SOLAR RADIATION MAPS FOR ANDALUCIA BASED ON NEURAL NETWORKS PREDICTIONS

摘要

In this work an application of a methodology for obtaining solar radiation maps is presented. This work is an extension of the results obtained before when radiation maps for a province of Spain (Jaen) where developed. For obtaining a solar radiation map is necessary to know the solar radiation of many points wide spread the zone of the map where it is going to be drawn. For most of the locations all over the world the records of these data (solar radiation in whatever scale, daily or hourly values) are non existent. Only very few locations have the privilege of having good meteorological stations where records of solar radiation have being registered. But even in those locations with historical records of solar data, the quality of these solar series is not as good as it should be for most of the purposes. In addition to, for drawing a solar radiation map, the amount of points of the maps (real sites) that it is necessary to work with makes this problem difficult to solve. Nevertheless, with the application of the methodology proposed in this article, this problem has been solved and solar radiation maps have been obtained for Andalucia, the most southern region of Spain situated between the parallels 38°40′ N and 36°00′ N, and the meridians 7°30′ W and 1°40′ W.
