The scarcity of global irradiation data is the reason for using sunshine hours in order to estimate them through different correlations which have shown a good fit with the measurements data. In order to draw charts with the spatial distribution of the sunshine-hours monthly averages (and from them, global solar radiation charts also) on such a vast territory as South America, it is necessary to study the error-...
