Unsupervised Classification of Solar Radiation Daily Data
Abstract
In this work we present the applicability of cluster analysis in the issue of determining the behaviour and structure of daily solar radiation in a specific emplacement. In solar radiation assessment, classifications of the days according to the radiation integrate are often used. However it is known that this kind of classifications usually presents deficiencies. They don't collect all the aspects that could distinguish days, and also, they can classify days in the same group but presenting, for example, different behaviour in an energy production sense.
