Prediction of the intensity of direct solar irradiation

Abstract

This article contains instructions for calculating the maximum intensity of solar irradiation reaching Earth's surface every minute of the day throughout the year. This radiation can be measured and subsequently used for prediction of solar irradiation. But due to frequent occurrence of days with cloud cover are not the measured data complete. Therefore, to calculate the missing values using the appropriate functions to the measured values that could reach the solar irradiance in clear sky. Methods were necessary to clarify the effects of weather prediction for the optimal consumption of thermal energy for district heating in urban areas.
