Zusammenfassung
A model of solar irradiance on arbitrarily oriented inclined surfaces
is proposed, based on fuzzy logic procedures. The behavior of the
proposed model is similar to that of other models of increased performance
such as the models of Perez or Gueymard, though it requires only
a very limited number of classes and adjustable parameters. The use
of fuzzy clustering optimizes the number and definition of the sky
categories. The model considers overlapping clusters and allows an
improved description of the sky situations close to the transition
zone between contiguous categories.
