Angström-Prescott empirical model to estimate solar radiation in Norte de Santander, Colombia

The document shows the application of empirical Angström-Prescott model in different places Norte de Santander, Colombia. estimates solar radiation from hours sunlight, at a site where brightness and are measured. data were obtained Institute Hydrology, Meteorology Environmental Studies, IDEAM; algorithms developed RStudio to process analyze information. establishes linear relationship between specific geographic location. Therefore, regression analyzes performed for three sites, using historical records radiation, obtaining R-squared coefficients of: 0.73, 0.78, 0.42. models then extrapolated nearby regions with records, but without data, obtain an estimate these locations. Finally, database was created monthly average information on various subregions which can be used design implementation photovoltaic systems.
