Establishing new empirical models for predicting monthly mean horizontal diffuse solar radiation in city of Isfahan, Iran

Models for the estimation of diffuse solar radiation for typical cities in Turkey

“…The average values of the estimations by these models for every K T and n/N values are used to calibrate the new models. Here, the purpose is to eliminate the differences among model predictions since the selection of the appropriate model is impossible without experimental data [10,42,43].…”

“…The data of bright sunshine hours and global solar radiation was obtained from fifteen meteorological stations during the period between 1981 and 1987. Sabzpooshani and Mohammadi [10] established new empirical models for predicting the monthly mean diffuse solar radiation on a horizontal surface for city of Isfahan situated in central part of Iran. The empirical models from previous studies were nominated and, diffuse fraction was calculated from function of the relative sunshine duration and clearness index.…”

Prediction of monthly average global solar radiation based on statistical distribution of clearness index

“…[11]. The accuracy of the new model was compared with the existing models and found to be more accurate.…”

Photovoltaic forecasting through establishing solar models without using diffuse radiation measurement in Beijing

“…[1][2][3][4][5] Researchers have developed many empirical equations to estimate determine diffuse component using the empirical models including sunshine duration, global solar radiation and extraterrestrial solar radiation. The typical models are Temps and Coulson model, Liu and Jordan model, Page model and Erbs model [5][6][7][8].…”
