The article presents the implementation of an autoregressive model for predicting solar radiation data. An experiment was carried out with some approaches to data imputation and the choice of the MICE (Multiple Imputation by Chained Equation) approach was justified. A comparative experiment was also carried out for predicting solar radiation based on initial data and based on data in which imputation was applied.
