Solar radiation models

Brief:

I have reviewed some solar radiation models for predicting the average daily and hourly global radiation, beam radiation and diffuse radiation. Seven models using the Angstrom–Prescott equation to predict the average daily global radiation with hours of sunshine are considered. The average daily global radiation for Hong Kong (22.3^oN latitude, 114.3^oE longitude) is predicted. Estimations of monthly average hourly global radiation are discussed. Two parametric models are reviewed and used to predict the hourly irradiance of Hong Kong. Comparisons among model predictions with measured data are made.
