Caracterización de la irradiancia solar difusa sobre superficies verticales (characterisation of solar diffuse irradiance on vertical surfaces)

Abstract

TITLE: Characterisation of Solar Diffuse Irradiance on Vertical Surfaces. This Thesis is focused on the characterisation of solar diffuse irradiance on vertical surfaces pointing the cardinal directions. Obtained results are worth of interest in Energy Engineering. Observations have been obtained by the MK6 device, a designed multidirectional radiometric station prototype. Moreover, the optimal correction factor for the taken measures has been provided. Through the taken measures, we have identified skies in Burgos from september 2014 to april 2015 according to the CIE 2004 Standard classification. Furthermore, a study comparing 9 classical clear indexes with the CIE Standards has been carried out. On the other hand, albedo's irradiance has been characterised according to 4 models. Finally, an exhaustive review of transposition models have been studied for 10-minutes inteval difuse irradiance values on North, South, East and West pointing to surfaces, and three types of sky conditions. The analysis comprises the results of several statistical estimators, including a new one proposed by the author. KEYWORDS: Solar energy, diffuse irradiance, measurement, modelling, statistics.
