Availability and Variability of Solar Radiation Data for the Modelling of Solar Thermal Installations in Andalusia (Spain)
Abstract
A comprehensive analysis was carried out on the data from various weather station networks in Andalusia (Southern Spain) and standard climate data sources. Special attention was given to characterizing the different sources of uncertainty that need to be taken into account when inputting solar radiation data used for solar thermal system modelling - in terms of geographical and statistical representativeness and in terms of the estimation/measuring procedure considered in direct and diffuse fraction decomposition, a key factor in concentrating solar system simulation.
