The model estimates solar radiation from hours of sunlight, at a site where brightness and solar radiation are measured. The data were obtained from the Institute of Hydrology, Meteorology and Environmental Studies, IDEAM; algorithms were developed in RStudio to process and ana-lyze the information. The model establishes a linear relationship between solar radiation and the hours of sunlight, in a specific geographic location. Therefore, regression analyzes were performed for three different sites, using histori-cal records of brightness and solar radiation, ob-taining the R-squared coefficients of: 0.73, 0.78,and 0.42. The models were then extrapolated to nearby regions with solar brightness records, but without solar radiation data, to obtain an estimate of radiation at these locations. Finally, a database was created with monthly aver-age information on solar radiation for various subregions of Norte de Santander, which can be used for the design and implementation of photovoltaic systems.", year = 2021, publisher = "Revista de Investigación Desarrollo e Innovación: RIDI", url = "https://repositorio.ufps.edu.co/handle/ufps/919", }
