  Assessing the ARIMA Model for Estimating Monthly Solar Irradiance from Approximated Daily Data in Uyo, Nigeria

  By Samuel Edet Bassey

  Abstract: This study assesses ARIMA models for capturing, predicting, and visualizing solar irradiance patterns in Uyo, Nigeria. Previous studies specific to Uyo solar irradiance forecasting explored regression models, which are not suitable for advanced analysis. This gap presented a challenge for accurate energy forecasting, grid integration, and planning. This study utilizes a dataset of approximated solar irradiance values, trained and tested on ARIMA for suitability. The methodology comprises the study location …
