Modeling of cloudiness based on the difference between the theoretical solar irradiance and the real solar irradiance on the earth's surface for the installation of photovoltaic energy projects
Abstract: Considering that the solar irradiance on the surface is a direct indicator of cloudiness [1], we proceeded to make a model that determines the cloudiness, contrasting the differences that are generated between the theoretical solar irradiance estimated on the surface [1] [2] and real solar irradiance recorded on the surface. To evaluate the quality of the model, the real cloud values and the estimates were contrasted in a dispersion diagram, both in eighths at the daily average level, obtaining a correlation coefficient of 0.7. The modeling of cloudiness is a relevant variable for the installation of photovoltaic energy projects.
