Solar radiation models for predicting the average daily and hourly global radiation, beam radiation and diffuse radiation are reviewed in this paper. Seven models using the Ångström–Prescott equation to predict the average daily global radiation with hours of sunshine are considered. The average ...
Solar radiation incident on the top of atmosphere can be treated as a traveling plane wave normal to the line between the centers of the Earth and the Sun. The solar radiation propagating through the atmosphere can be partitioned into direct and diffuse radiation. Direct radiation is sunlight th...

The solar radiation is first computed for clear-sky conditions, considering the different components of radiation: beam, diffuse and reflected radiations. The predicted real-sky radiation is computed daily starting from the results of clear-sky radiation, in terms of the clear-sky index, which ...

Finally, global solar radiation is the sum of the direct and diffuse solar radiation irradiating a flat horizontal surface. In this case, the contribution of the direct beam component is proportional to the cosine of the angle between the position of the sun in the sky and the normal (...

In this study the optimum tilt angle for south-facing solar surfaces in Tabass, Iran, for the fixed monthly, seasonal, semi-yearly and yearly adjustments were calculated. Due to lack of measured diffuse solar radiation data, to predict the horizontal diffuse radiation nine diffuse models from th...
A number of hourly measurements of global solar radiation on a horizontal surface, taken during the period 1981–1986 in Burgos, Spain, have been analyzed into diffuse and beam components. The components of global solar radiation were used to calculate the monthly average hourly and daily values ...
