In this work, a statistical correction of the distribution of solar radiation in Cuba is obtained, estimated by the Heliosat method, using the images collected from the GOES-13 satellite, for the period 2012-2017. The need arises for an improvement in the update of the distribution of solar radiation in the country, because taking into account that the last characterization for the national territory, of the distribution of this resource, refers to the research of the year 2018 and prior to this, to that of the 1986-1991 period; when the maps obtained are compared with the values ​​of the stations, a certain overestimation of the solar radiation values ​​is observed. An improvement in the estimation of said resource, is required as a result of the problem raised in question, given the importance of this information as a renewable source of energy and its use in the evaluation of the helioenergic potential of Cuba.
