Abstract

This paper discusses a procedure that was adopted for the development of a linear regression model for estimating solar radiation on horizontal surfaces for 7 Colombian zones. The correlations, the simulated global solar radiation on tilted surface and the simulated diffuse solar radiation on a horizontal surface for each zone are shown. The values of sunshine-hours and the solar radiation were taken from January 2012 to January 2013. The solar radiation values obtained were compared with the measured values. The obtained mean absolute percentage error was below 5%. The results of the global solar radiation show that the areas of greatest solar potential are Tibú> Baranoa> ICP> GRB> Morichal> Castilla> Guamues and the months of the year with the highest solar radiation are June, July and August.
